Electromagnetic pumps can provide power for the transmission of liquid metals and are widely used in nuclear power plant fast neutron reactor cooling, metal smelting and manufacturing industries.

At present, electromagnetic pumps are mainly divided into two categories: conductive electromagnetic pumps and inductive electromagnetic pumps.

Detailed ways

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

As shown in Figures 1 and 2, the present application provides an induction electromagnetic pump 100, which is a planar induction electromagnetic pump with a pipe diameter of less than or equal to 10 mm, a flow rate of less than or equal to 20 L/h, and an output power of less than or equal to 3 W. The induction electromagnetic pump 100 of the present application can be used as a laboratory experimental pump, etc., for driving the directional flow of liquid metal.

Specifically, the induction electromagnetic pump 100 includes a base 11, a cover plate 12, a core assembly 13, a winding 14 and a flow channel 15. The base 11 and the cover plate 12 are connected to form a storage space for accommodating the core assembly 13, the winding 14 and the flow channel 15, so that the base 11 and the cover plate 12 become a basic frame supporting the core assembly 13, the winding 14 and the flow channel 15 after being connected, thereby facilitating the assembly and normal operation of the induction electromagnetic pump 100. The winding 14 is used to transmit current, and the winding 14 is wound on the core assembly 13, so that the core assembly 13 can generate a magnetic field through the current in the winding 14, thereby realizing electromagnetic induction. The flow channel 15 is used as a flow channel for liquid metal. In this application, the flow channel 15 with a rectangular cross section is used as an example.

In the present application, after the winding 14 is energized, the magnetic field generated by the core assembly 13 reacts with the liquid metal in the flow channel 15 to generate an induced current, and the liquid metal in the flow channel 15 becomes a current-carrying conductor, so that the liquid metal reacts with the magnetic field to generate electromagnetic force, thereby driving the liquid metal to flow in a directional manner.

In order to clearly illustrate the technical solution of the present application, front, back, left, right, top, and bottom are also defined as shown in FIG1 .

It should also be understood that the term "and/or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

As shown in Fig. 1 and Fig. 2, as an implementation, the core assembly 13 includes a first core 131 and a second core 132, and the first core 131 and the second core 132 are distributed along the left and right directions of the induction electromagnetic pump 100. The winding 14 is wound around the first core 131 and the second core 132, so that the first core 131 and the second core 132 can generate a magnetic field through the current in the winding 14, thereby realizing electromagnetic induction.

Specifically, along the up and down direction of the induction electromagnetic pump 100, the first iron core 131 and the second iron core 132 are at least partially located between the base 11 and the cover plate 12, and the first iron core 131 and the second iron core 132 are both abutted against the upper side of the base 11 and the lower side of the cover plate 12. Since the first iron core 131 and the second iron core 132 will attract each other, if only the first iron core 131 and the second iron core 132 are fixed to the base 11, the force generated by the mutual attraction between the first iron core 131 and the second iron core 132 will cause the base 11 to bend and deform, that is, the left and right sides of the base 11 will be bent upward. Therefore, through the setting of the cover plate 12 of the present application, the first iron core 131 and the second iron core 132 can be connected through the cover plate 12 and the base 11. At the same time, the first iron core 131 and the second iron core 132 are both abutted against the upper side of the base 11 and the lower side of the cover plate 12, so that the first iron core 131 and the second iron core 132 are fixed together by the cover plate 12 and the base 11, so that the bending stress of the base 11 caused by the first iron core 131 and the second iron core 132 is changed into the bending stress generated by the base 11 and the cover plate 12 at the same time. The bending stress generated by the base 11 and the cover plate 12 at the same time can be offset by the pressing force of the base 11 and the cover plate 12 on the first iron core 131 and the second iron core 132, so that the bending stress of the induction electromagnetic pump 100 as a whole is changed into compressive stress, so that the structural stress of the induction electromagnetic pump 100 is changed, thereby improving the overall stiffness of the induction electromagnetic pump 100, and facilitating the improvement of the service life of the induction electromagnetic pump 100.

As shown in Figures 2 and 3, more specifically, a first slot body 111 is opened on the upper side of the base 11, and the first slot body 111 at least partially protrudes upward to form a first partition 112. The height of the first partition 112 along the up and down direction of the induction electromagnetic pump 100 is greater than the depth of the first slot body 111 along the up and down direction of the induction electromagnetic pump 100, so that the first iron core 131 and the second iron core 132 are respectively abutted to the left and right sides of the first partition 112, and then the first partition 112 can position the first iron core 131 and the second iron core 132 to facilitate the assembly of the first iron core 131 and the second iron core 132.

A second slot 121 is provided on the lower side of the cover plate 12, and the second slot 121 at least partially protrudes downward to form a second partition 122. The height of the second partition 122 along the up and down direction of the induction electromagnetic pump 100 is greater than the depth of the second slot 121 along the up and down direction of the induction electromagnetic pump 100, so that the first iron core 131 and the second iron core 132 are respectively abutted to the left and right sides of the second partition 122, so that the second partition 122 can position the first iron core 131 and the second iron core 132 to facilitate the assembly of the first iron core 131 and the second iron core 132.

Among them, after the winding 14 is wound on the first iron core 131 and the second iron core 132, the upper and lower ends of the winding 14 at least partially protrude from the first iron core 131 and the second iron core 132, that is, the height of the winding 14 along the up and down direction of the induction electromagnetic pump 100 is greater than the height of the first iron core 131 along the up and down direction of the induction electromagnetic pump 100, or the height of the winding 14 along the up and down direction of the induction electromagnetic pump 100 is greater than the height of the second iron core 132 along the up and down direction of the induction electromagnetic pump 100. When the base 11 and the cover plate 12 are connected, in order to avoid the situation where the first iron core 131 and the second iron core 132 cannot abut the base 11 and/or the cover plate 12 due to the existence of the winding 14, the winding 14 of the present application is at least partially located in the first slot body 111 and the second slot body 121, so that the first slot body 111 and the second slot body 121 can provide a layout space for the winding 14, and it is beneficial for the first iron core 131 and the second iron core 132 to abut the base 11 and/or the cover plate 12, so that the base 11 and the cover plate 12 can generate a clamping force on the first iron core 131 and the second iron core 132, thereby converting the overall bending stress of the induction electromagnetic pump 100 into compressive stress, so that the structural stress of the induction electromagnetic pump 100 is changed, and it is beneficial to improve the overall stiffness and service life of the induction electromagnetic pump 100. In addition, through the above arrangement, the position of the winding 14 can be limited by the first slot body 111 and the second slot body 121, so that the first iron core 131 and the second iron core 132 can be positioned through the winding 14, which is beneficial to the normal operation of the induction electromagnetic pump 100.

In this embodiment, along the up-down direction of the induction electromagnetic pump 100, the flow channel 15 is located between the first partition 112 and the second partition 122, the flow channel 15 is respectively abutted to the upper side of the first partition 112 and the lower side of the second partition 122, and the flow channel 15 is also respectively connected to the upper side of the first partition 112 and the lower side of the second partition 122; along the left-right direction of the induction electromagnetic pump 100, the flow channel 15 is located between the first iron core 131 and the second iron core 132, the first iron core 131 and the second iron core 132 are respectively abutted to the left and right sides of the flow channel 15, and the first iron core 131 and the second iron core 132 are also respectively connected to the left and right sides of the flow channel 15. Since the flow channel 15 of the induction electromagnetic pump 100 of the present application has a small diameter, when the fluid flows through the small-section flow channel 15, according to the Bernoulli principle, the tube walls on both sides of the flow channel 15 will be adsorbed to the middle, thereby causing blockage of the flow channel 15. Through the arrangement of the present application, that is, through the first partition 112, the second partition 122, the first iron core 131 and the second iron core 132, the four sides of the flow channel 15 are connected respectively, so as to prevent the side wall 1251 of the flow channel 15 from being adsorbed toward the middle, thereby effectively reducing the influence of the Bernoulli principle on the flow channel 15, so as to improve the operating stability and overall structural rigidity of the induction electromagnetic pump 100, and help to increase the service life of the induction electromagnetic pump 100.

Exemplarily, a horizontal plane 101 perpendicular to the up and down direction of the induction electromagnetic pump 100 is defined. The induction electromagnetic pump 100 of the present application can improve the overall stiffness of the induction electromagnetic pump 100 through the structural arrangement of the base 11, the cover plate 12, the first iron core 131 and the second iron core 132, so that when the induction electromagnetic pump 100 works continuously for thirty days, if any part of the base 11, the cover plate 12, the first iron core 131 and/or the second iron core 132 is bent, the angle between the upper surface of the bent base 11, the cover plate 12, the first iron core 131 and/or the second iron core 132 and the horizontal plane 101 is less than 1°, and/or the angle between the lower surface of the bent base 11, the cover plate 12, the first iron core 131 and/or the second iron core 132 and the horizontal plane 101 is less than 1°.

As shown in FIG. 4 , as another implementation, the induction electromagnetic pump 100 includes a first partition 112 located in the first trough body 111 and a second partition 122 located in the second trough body 121, the first partition 112 is connected to the bottom of the first trough body 111 and divides the first trough body 111 into two first partition grooves, and the second partition 122 is connected to the bottom of the second trough body 121 and divides the second trough body 121 into two second partition grooves. That is, in this embodiment, the first partition 112 and the first trough body 111 are two separate parts, and the first partition 112 and the first trough body 111 are connected by glue; the second partition 122 and the second trough body 121 are two separate parts, and the second partition 122 and the second trough body 121 are connected by glue. Among them, since the induction electromagnetic pump 100 of the present application is used in a laboratory environment, and the indoor environment cannot reach a higher temperature, the glue of the present application is a high-temperature resistant glue that is resistant to 180°C, such as epoxy glue.

In this embodiment, when the first partition 112 and the first tank body 111 are two separate components, and the second partition 122 and the second tank body 121 are two separate components, the first partition 112 and the second partition 122 are made of ceramic material.

It should be noted that the first partition 112 and the first groove body 111 are defined as two separate components, and the second partition 122 and the second groove body 121 are defined as two separate components as a first structure. The first partition 112 is formed by the upward protrusion of the first groove body 111, and the second partition 122 is formed by the downward protrusion of the second groove body 121 as a second structure. The effects of the first structure and the second structure are the same and will not be repeated here.

As shown in Fig. 2, as an implementation, the induction electromagnetic pump 100 includes a fastener 16 and a connector 17, and the connector 17 is used to cooperate with the fastener 16 for fixing. The fastener 16 can be a bolt, and the connector 17 can be a nut, so that the fastener 16 and the connector 17 can be fixed to each other.

Specifically, the fastener 16 is passed through the cover plate 12 , the core assembly 13 and the base 11 and then fixed by the connecting piece 17 .

More specifically, a plurality of fasteners 16 and connectors 17 are provided, a portion of the fasteners 16 are passed through the cover plate 12, the first iron core 131 and the base 11 and are fixed by corresponding connectors 17, and another portion of the fasteners 16 are passed through the cover plate 12, the second iron core 132 and the base 11 and are fixed by corresponding connectors 17.

Through the above arrangement, the fastener 16 can pass through the first core 131 and be connected to the base 11 and the cover plate 12 at the same time, and the fastener 16 can pass through the second core 132 and be connected to the base 11 and the cover plate 12 at the same time, so that the first core 131 and the second core 132 can be fixed to avoid the mutual attraction force of the first core 131 and the second core 132 causing the base 11 and/or the cover plate 12 to bend and deform, and then the bending stress generated by the base 11 and the cover plate 12 at the same time can be offset by the pressing force of the base 11 and the cover plate 12 on the first core 131 and the second core 132, so that the structural stress of the induction electromagnetic pump 100 is changed, which is conducive to improving the overall stiffness of the induction electromagnetic pump 100 and the service life of the induction electromagnetic pump 100. In addition, through the above arrangement, the vibration and noise generated by the induction electromagnetic pump 100 during operation can also be reduced, thereby further improving the structural strength of the induction electromagnetic pump 100.

It should be noted that the fastener 16 can be set as a stud bolt, so that the fastener 16 can pass through the various components of the induction electromagnetic pump 100 from bottom to top or from top to bottom, and the two ends of the fastener 16 are fixed by two connecting pieces 17 to realize the assembly of the induction electromagnetic pump 100.

Exemplarily, a plurality of first fixed through holes 1311 and second fixed through holes 1321 are provided, and the plurality of first fixed through holes 1311 are evenly distributed on the first iron core 131 along the front-to-back direction of the induction electromagnetic pump 100, and the plurality of second fixed through holes 1321 are evenly distributed on the second iron core 132 along the front-to-back direction of the induction electromagnetic pump 100, and the first lower through hole 114 and the second lower through hole 114 are symmetrically arranged with respect to the left-to-right direction of the induction electromagnetic pump 100.

Exemplarily, the axes of the first upper through hole 123, the first lower through hole and the first fixed through hole 1311 all extend in the up-down direction of the induction electromagnetic pump 100, and the number of the first upper through hole 123, the first lower through hole and the first fixed through hole 1311 is consistent; the axes of the second upper through hole 124, the second lower through hole 114 and the second fixed through hole 1321 all extend in the up-down direction of the induction electromagnetic pump 100, and the number of the second upper through hole 124, the second lower through hole 114 and the second fixed through hole 1321 is consistent.

As an implementation method, the flow channel 15 and the first partition 112, and the flow channel 15 and the second partition 122 are connected by glue; the flow channel 15 and the first iron core 131, and the flow channel 15 and the second iron core 132 are connected by glue. Through the above arrangement, the first iron core 131, the second iron core 132, the first partition 112 and the second partition 122 can be used as the support structure of the flow channel 15, thereby reducing the influence of the Bernoulli principle on the flow channel 15, thereby improving the operation stability and overall structural rigidity of the induction electromagnetic pump 100, and facilitating the service life of the induction electromagnetic pump 100.

It should be noted that the present application only uses glue as an implementation method. The specific connection method between the flow channel 15 and the first partition 112, between the flow channel 15 and the second partition 122, and between the flow channel 15 and the first iron core 131, and between the flow channel 15 and the second iron core 132 can be selected according to actual conditions, and the present application does not impose any restrictions.

As shown in Fig. 2 and Fig. 5, as an optional implementation, the first core 131 includes a first tooth portion 1312 and a first yoke portion 1313, and the first tooth portion 1312 and the first yoke portion 1313 are integrally formed. The second core 132 includes a second tooth portion 1322 and a second yoke portion 1323, and the second tooth portion 1322 and the second yoke portion 1323 are integrally formed.

Specifically, when observing from the upper and lower directions of the induction electromagnetic pump 100, the first tooth portion 1312 and the second tooth portion 1322 both at least partially overlap with the first slot body 111, the first tooth portion 1312 and the second tooth portion 1322 both at least partially overlap with the second slot body 121, and the first slot body 111 and the second slot body 121 at least partially overlap; the winding 14 is respectively wound on the first tooth portion 1312 and the second tooth portion 1322, so that the winding 14 can be located in the first slot body 111 and the second slot body 121.

When the base 11 and the cover plate 12 are connected, the above-mentioned arrangement can prevent the part of the winding 14 protruding from the first tooth portion 1312 and the second tooth portion 1322 from affecting the connection between the base 11 and the cover plate 12, thereby avoiding the situation where the first iron core 131 and the second iron core 132 cannot fit the base 11 and/or the cover plate 12, that is, the first slot body 111 of the present application can provide an arrangement space for the winding 14 wound on the first tooth portion 1312 and the second tooth portion 1322, and the second slot body 121 can provide an arrangement space for the winding 14 wound on the first tooth portion 1312 and the second tooth portion 1322, and it is beneficial for the first iron core 131 and the second iron core 132 to fit the base 11 and/or the cover plate 12, so that the base 11 and the cover plate 12 can generate a pressing force on the first iron core 131 and the second iron core 132, thereby changing the structural stress of the induction electromagnetic pump 100, and it is beneficial to improve the overall stiffness and service life of the induction electromagnetic pump 100.

In this embodiment, the first partition portion 112 divides the first slot body 111 into two first partition slot bodies 1111, and the widths of the two first partition slot bodies 1111 along the left-right direction of the induction electromagnetic pump 100 are basically the same; the second partition portion 122 divides the second slot body 121 into two second partition slot bodies 1211, and the widths of the two second partition slot bodies 1211 along the left-right direction of the induction electromagnetic pump 100 are basically the same; the winding 14 is at least partially located in the two first partition slot bodies 1111 and the two second partition slot bodies 1211, respectively.

Among them, the first partition part 112 basically extends along the front-to-back direction of the induction electromagnetic pump 100, and the second partition part 122 basically extends along the front-to-back direction of the induction electromagnetic pump 100, so that the two first partition grooves 1111 and the two second partition grooves 1211 basically extend along the front-to-back direction of the induction electromagnetic pump 100.

Exemplarily, the two first dividing slots 1111 are used to accommodate the lower end of the winding 14, and the two second dividing slots 1211 are used to accommodate the upper end of the winding 14. More specifically, one first dividing slot 1111 is used to accommodate the lower end of the winding 14 wound on the first tooth portion 1312, another first dividing slot 1111 is used to accommodate the lower end of the winding 14 wound on the second tooth portion 1322, one second dividing slot 1211 is used to accommodate the upper end of the winding 14 wound on the first tooth portion 1312, and another second dividing slot 1211 is used to accommodate the upper end of the winding 14 wound on the second tooth portion 1322.

Through the above-mentioned arrangement, along the left-right direction of the induction electromagnetic pump 100, the first dividing slot body 1111 and the second dividing slot body 1211 located on the same side can define the position of the winding 14 on the first tooth portion 1312, and the first dividing slot body 1111 and the second dividing slot body 1211 located on the other side can define the position of the winding 14 on the second tooth portion 1322, thereby realizing the positioning of the winding 14 and further defining the position of the first iron core 131 and the second iron core 132.

As an implementation, a longitudinal plane 102 perpendicular to the left-right direction of the induction electromagnetic pump 100 is defined, the longitudinal plane 102 substantially divides the induction electromagnetic pump 100 in half, and the second tooth portion 1322 and the first tooth portion 1312 are symmetrically arranged about the longitudinal plane 102. This application takes the first tooth portion 1312 as an example for description.

As shown in Figure 6, when observed from the upper and lower directions of the induction electromagnetic pump 100, the portion where the first tooth portion 1312 overlaps with the first slot body 111 is the first portion, and the ratio of the length L1 of the first tooth portion 1312 in the left-right direction of the induction electromagnetic pump 100 to the length L2 of the first portion in the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 0.1 and less than or equal to 1; the portion where the first tooth portion 1312 overlaps with the second slot body 121 is the second portion, and the ratio of the length L1 of the first tooth portion 1312 in the left-right direction of the induction electromagnetic pump 100 to the length L3 of the second portion in the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 0.1 and less than or equal to 1. Specifically, the ratio of the length L1 of the first tooth portion 1312 in the left-right direction of the induction electromagnetic pump 100 to the length L2 of the first part in the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 0.5 and less than or equal to 0.7; the ratio of the length L1 of the first tooth portion 1312 in the left-right direction of the induction electromagnetic pump 100 to the length L3 of the second part in the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 0.5 and less than or equal to 0.7.

Through the above arrangement, it is possible to avoid the situation where the length ratio of the first tooth portion 1312 and the first part in the left-right direction of the induction electromagnetic pump 100 is too large, resulting in the inability to place the winding 14 in the first slot body 111 and the second slot body 121, thereby achieving the fitting of the first iron core 131 and the base 11, and the fitting of the first iron core 131 and the cover plate 12, and thus facilitating the fixation of the first iron core 131 by the base 11 and the cover plate 12; it is also possible to avoid the situation where the length ratio of the first tooth portion 1312 and the first part in the left-right direction of the induction electromagnetic pump 100 is too small, resulting in the inability to arrange the winding 14 that can drive the flow of liquid metal, so that the first iron core 131 can cooperate with the second iron core 132 to drive the flow of liquid metal.

It should be noted that the effect of the length ratio of the first tooth portion 1312 and the second portion in the left and right directions of the induction electromagnetic pump 100 being too large or too small is consistent with the effect of the length ratio of the first tooth portion 1312 and the first portion in the left and right directions of the induction electromagnetic pump 100 being too large or too small, and will not be repeated here.

As an implementation method, the material of the base 11 needs to be a pressure-resistant, high-temperature-resistant, non-magnetic, and non-conductive material. In the present application, the base 11 can be made of stainless steel or aluminum; the material of the cover 12 also needs to be a pressure-resistant, high-temperature-resistant, non-magnetic, and non-conductive material. In the present application, the cover 12 is made of stainless steel or aluminum; the material of the flow channel 15 needs to be a corrosion-resistant, non-conductive, and non-magnetic material. In the present application, the flow channel 15 is made of polytetrafluoroethylene.

As shown in FIG7 , as an implementation, the induction electromagnetic pump 100 further includes a connecting pipe 18, which is used to connect the flow channel 15 and the pipe of the external device, so that the induction electromagnetic pump 100 is connected to the external device for the transportation of liquid metal. The connecting pipe 18 includes a first port 181 and a second port 182, the inner contour of the first port 181 is consistent with the inner contour of the opening of the flow channel 15, the first port 181 and the opening of the flow channel 15 are connected or integrally formed, and the inner contour of the second port 182 is different from the inner contour of the first port 181, so that the second port 182 is connected to the pipe of the external device, wherein the inner contour of the pipe of the external device is different from the inner contour of the opening of the flow channel 15. Through the above-mentioned setting, the flow channel 15 can be connected to any pipe of the external device through the connecting pipe 18, thereby improving the convenience of connecting the induction electromagnetic pump 100 with the external device.

It should be noted that the inner contour of the second port 182 can be adjusted according to the shape of the pipeline of the actual external device, so as to improve the versatility of the induction electromagnetic pump 100.

Exemplarily, the second port 182 and the pipeline of the external device may also be connected via a flange, which is not limited in the present application.

As shown in FIG6 , as an implementation, the ratio of the depth H1 of the first trough 111 along the vertical direction of the induction electromagnetic pump 100 to the height H2 of the base 11 along the vertical direction of the induction electromagnetic pump 100 is greater than or equal to 0.1 and less than or equal to 0.8; the ratio of the depth H3 of the second trough 121 along the vertical direction of the induction electromagnetic pump 100 to the height H4 of the cover plate 12 along the vertical direction of the induction electromagnetic pump 100 is greater than or equal to 0.1 and less than or equal to 0.8. Specifically, the ratio of the depth H1 of the first trough 111 along the vertical direction of the induction electromagnetic pump 100 to the height H2 of the base 11 along the vertical direction of the induction electromagnetic pump 100 is greater than or equal to 0.3 and less than or equal to 0.6; the ratio of the depth H3 of the second trough 121 along the vertical direction of the induction electromagnetic pump 100 to the height H4 of the cover plate 12 along the vertical direction of the induction electromagnetic pump 100 is greater than or equal to 0.3 and less than or equal to 0.6.

Through the above arrangement, it is possible to prevent the depth H1 of the first slot body 111 from being too large, which may lead to a decrease in the structural strength of the base 11, and it is also possible to prevent the depth H1 of the first slot body 111 from being too small, which may lead to insufficient arrangement space for the winding 14, thereby improving the structural strength of the base 11 when the first slot body 111 has sufficient space to accommodate the winding 14. In addition, through the above arrangement, it is possible to prevent the depth H3 of the second slot body 121 from being too large, which may lead to a decrease in the structural strength of the cover plate 12, and it is also possible to prevent the depth H3 of the second slot body 121 from being too small, which may lead to insufficient arrangement space for the winding 14, thereby improving the structural strength of the cover plate 12 when the second slot body 121 has sufficient space to accommodate the winding 14.

In this embodiment, the ratio of the height H5 of the first partition 112 along the vertical direction of the induction electromagnetic pump 100 to the depth H1 of the first tank body 111 along the vertical direction of the induction electromagnetic pump 100 is greater than 1 and less than or equal to 1.5; the ratio of the height H6 of the second partition 122 along the vertical direction of the induction electromagnetic pump 100 to the depth H3 of the second tank body 121 along the vertical direction of the induction electromagnetic pump 100 is greater than 1 and less than or equal to 1.5. Specifically, the ratio of the height H5 of the first partition 112 along the vertical direction of the induction electromagnetic pump 100 to the depth H1 of the first tank body 111 along the vertical direction of the induction electromagnetic pump 100 is greater than or equal to 1.1 and less than or equal to 1.4; the ratio of the height H6 of the second partition 122 along the vertical direction of the induction electromagnetic pump 100 to the depth H3 of the second tank body 121 along the vertical direction of the induction electromagnetic pump 100 is greater than or equal to 1.1 and less than or equal to 1.4. Through the above arrangement, it is possible to prevent the height H5 of the first partition 112 from being too small, which causes the first iron core 131 and the second iron core 132 to be unable to abut against the first partition 112, thereby improving the positioning accuracy of the first iron core 131 and the second iron core 132; it is also possible to prevent the height H5 of the first partition 112 from being too large, which causes the distance of the flow channel 15 along the vertical direction of the induction electromagnetic pump 100 to become smaller, thereby improving the flow rate of the flow channel 15, and further improving the working efficiency of the induction electromagnetic pump 100. In addition, through the above arrangement, it is possible to prevent the height H6 of the second partition 122 from being too small, which causes the first iron core 131 and the second iron core 132 to be unable to abut against the second partition 122, thereby improving the positioning accuracy of the first iron core 131 and the second iron core 132; it is also possible to prevent the height H6 of the second partition 122 from being too small, which causes the distance of the flow channel 15 along the vertical direction of the induction electromagnetic pump 100 to become smaller, thereby improving the flow rate of the flow channel 15, and further improving the working efficiency of the induction electromagnetic pump 100.

Exemplarily, the width W1 of the first partition 112 along the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 2 mm and less than or equal to 10 mm; the width W2 of the second partition 122 along the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 2 mm and less than or equal to 10 mm. Specifically, the width W1 of the first partition 112 along the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 5 mm and less than or equal to 7 mm; the width W2 of the second partition 122 along the left-right direction of the induction electromagnetic pump 100 is greater than or equal to 5 mm and less than or equal to 7 mm. Through the above arrangement, it is possible to avoid the width of the first partition 112 and the second partition 122 being too small, resulting in a smaller space for the fixed flow channel 15, thereby providing sufficient layout space for the flow channel 15, and preventing the layout space of the flow channel 15 from being too small, resulting in a flow rate of the flow channel 15 being too small. In addition, through the above-mentioned arrangement, it is possible to avoid the width of the first partition 112 and the second partition 122 being too large, which would result in a smaller volume of the winding 14, the first iron core 131 and the second iron core 132, so that after the winding 14 is energized, the magnetic field generated by the first iron core 131 and the second iron core 132 can drive the flow of liquid metal.

As shown in Figures 8 to 10, as an implementation method, the slot type of the core assembly 13 of the present application can be an open slot, a semi-closed slot or a closed slot, and the present application does not limit it. As shown in Figures 2 and 8, the winding 14 on the core assembly 13 can be a concentrated winding 14 or a distributed winding 14, and the present application does not limit it.

As shown in Figures 11 and 12, as an implementation method, the induction electromagnetic pump 100 also includes a side heat dissipation component 19 and a heat dissipation slot component 21 (refer to Figure 1). Among them, along the up and down direction of the induction electromagnetic pump 100, the side heat dissipation component 19 is located between the base 11 and the cover plate 12, and the side heat dissipation component 19 is respectively abutted against the lower side of the cover plate 12 and the upper side of the base 11, so that the side heat dissipation component 19 is fixed by the connection between the base 11 and the cover plate 12. The heat dissipation slot component 21 is respectively located on the base 11 and the cover plate 12, that is, the base 11 and the cover plate 12 are both provided with a heat dissipation slot component 21, and the heat dissipation slot component 21 is used to cooperate with the side heat dissipation component 19 to achieve side heat dissipation of the induction electromagnetic pump 100. Specifically, the heat dissipation slot component 21 and the side heat dissipation component 19 are located on the left and right sides of the induction electromagnetic pump 100, so as to achieve heat dissipation of the iron core component 13 on the left and right sides of the induction electromagnetic pump 100.

Specifically, the side heat dissipation assembly 19 includes a first side heat sink 191 and a second side heat sink 192, the first side heat sink 191 abuts against the first iron core 131, and the second side heat sink 192 abuts against the second iron core 132, so that during the operation of the induction electromagnetic pump 100, the heat generated from the winding 14 is transferred to the first iron core 131 and then transferred to the first side heat sink 191, and the heat generated from the winding 14 is transferred to the second iron core 132 and then transferred to the second side heat sink 192, so as to facilitate the heat conduction of the induction electromagnetic pump 100, and further facilitate the external cooling device to dissipate the heat of the induction electromagnetic pump 100 through the first side heat sink 191 and the second side heat sink 192. Among them, the external cooling device can be a fan, an air conditioner, etc.

Along the left-right direction of the induction electromagnetic pump 100, the first iron core 131 is located between the first side heat sink 191 and the second side heat sink 192, and the second iron core 132 is located between the first iron core 131 and the second side heat sink 192. Along the up-down direction of the induction electromagnetic pump 100, the first side heat sink 191 and the second side heat sink 192 are both located between the base 11 and the cover plate 12.

Specifically, the heat sink assembly 21 includes a first heat sink 211 (refer to FIG. 3 ) and a second heat sink 212 (refer to FIG. 1 ), and the first heat sink 211 and the second heat sink 212 are distributed along the left and right directions of the induction electromagnetic pump 100. The first heat sink 211 is respectively opened on the upper side of the base 11 and the lower side of the cover plate 12, and the second heat sink 212 is respectively opened on the upper side of the base 11 and the lower side of the cover plate 12. The first heat sink 211 is connected to the first side heat sink 191 and the outside world, and the second heat sink 212 is connected to the second side heat sink 192 and the outside world, so that the external cooling wind delivered to the first side heat sink 191 can be output to the outside world from the first heat sink 211, and the external cooling wind delivered to the second side heat sink 192 can be output to the outside world from the second heat sink 212. Among them, the external cooling wind can be provided by an external cooling device.

More specifically, external cooling air is respectively delivered from the external cooling device to the first side heat sink 191 and the second side heat sink 192; the external cooling air delivered to the first side heat sink 191 can be directly delivered to the outside from the first heat sink 211, and/or the external cooling air delivered to the first side heat sink 191 can be first delivered to the first iron core 131 and then delivered to the outside from the first heat sink 211; the external cooling air delivered to the second side heat sink 192 can be directly delivered to the outside from the second heat sink 212, and/or the external cooling air delivered to the second side heat sink 192 can be first delivered to the second iron core 132 and then delivered to the outside from the second heat sink 212.

Through the above-mentioned arrangement, the cooperation of the side heat dissipation assembly 19 and the heat dissipation slot assembly 21 can enable external cooling air to better dissipate heat for the first iron core 131 and the second iron core 132, so that the heat transferred from the winding 14 to the first iron core 131 and the second iron core 132 can be dissipated faster, thereby improving the heat dissipation efficiency of the induction electromagnetic pump 100.

As shown in FIG. 12 and FIG. 13 , as an implementation, along the left-right direction of the induction electromagnetic pump 100, the cover plate 12 is provided with a first arc groove 125 and a second arc groove 126 on both sides, and the base 11 is provided with a third arc groove 115 and a fourth arc groove 116 on both sides. The first arc groove 125 and the third arc groove 115 are symmetrically arranged in the vertical direction of the induction electromagnetic pump 100, the second arc groove 126 and the fourth arc groove 116 are symmetrically arranged in the vertical direction of the induction electromagnetic pump 100, and the first arc groove 125 and the second arc groove 126 are symmetrically arranged in the left-right direction of the induction electromagnetic pump 100. That is, the structures of the first arc groove 125, the second arc groove 126, the third arc groove 115 and the fourth arc groove 116 are basically the same, and they differ only in the arrangement positions.

Among them, the first arc groove 125 and the third arc groove 115 constitute the first heat dissipation groove 211, and the second arc groove 126 and the fourth arc groove 116 constitute the second heat dissipation groove 212. Specifically, the first arc groove 125 is located on the upper side of the third arc groove 115, and the second arc groove 126 is located on the upper side of the fourth arc groove 116. Along the up and down direction of the induction electromagnetic pump 100, the first side heat sink 191 is located between the first arc groove 125 and the third arc groove 115, and the second side heat sink 192 is located between the second arc groove 126 and the fourth arc groove 116, so as to facilitate the cooperation between the first side heat sink 191, the first arc groove 125 and the third arc groove 115, and facilitate the cooperation between the second side heat sink 192, the second arc groove 126 and the fourth arc groove 116, so as to further improve the heat dissipation efficiency of the induction electromagnetic pump 100.

In the present application, the first arc groove 125 is taken as an example for description.

As an implementation method, the first arc-shaped groove 125 includes two side walls 1251 and a bottom surface 1252, the two side walls 1251 are connected to the bottom surface 1252, the two side walls 1251 are perpendicular to the front-to-back direction of the induction electromagnetic pump 100, and the bottom surface 1252 is an arc surface. In the direction from close to the flow channel 15 to away from the flow channel 15, the distance between the bottom surface 1252 and the lower surface of the cover plate 12 gradually increases; the first arc-shaped groove 125 is also connected to the side of the cover plate 12, so as to facilitate the external cooling air to be transported from the side of the cover plate 12 to the outside.

Specifically, after the external cooling air is delivered to the first side heat sink 191 and/or the first iron core 131, it enters the first arc-shaped groove 125 through the upper opening of the first arc-shaped groove 125 and moves along the arc-shaped bottom surface 1252 so that the bottom surface 1252 can guide the external cooling air, thereby allowing the external cooling air to be smoothly delivered to the outside from the side of the cover plate 12.

It should be noted that the principles of the second arc groove 126 , the third arc groove 115 and the fourth arc groove 116 are consistent with the principle of the first arc groove 125 , and are not repeated here.

As shown in FIG14 , as an implementation method, the first side heat sink 191 includes an integrally formed transverse sheet 1911 and a plurality of vertical sheets 1912, the plurality of vertical sheets 1912 are distributed on the transverse sheet 1911 along the front-rear direction of the induction electromagnetic pump 100, and a heat dissipation channel 1913 is formed between any two vertical sheets 1912, and the heat dissipation channel 1913 is connected to the first iron core 131, the first heat dissipation slot 211 and the outside world respectively. Through the above arrangement, the external cooling air can be transported to the first iron core 131 through the heat dissipation channel 1913, and then transported to the first heat dissipation slot 211 through the heat dissipation channel 1913, and then transported to the outside world from the first heat dissipation slot 211; and/or the external cooling air can be transported to the first heat dissipation slot 211 through the heat dissipation channel 1913, and then transported to the outside world from the first heat dissipation slot 211.

Specifically, the first heat dissipation slots 211 are provided with a plurality of vertical sheets 1912, which are abutted against the solid part between two adjacent first heat dissipation slots 211. The solid part is the lower surface of the cover plate 12 or the upper surface of the base 11. That is, the vertical sheet 1912 abuts against the part between two adjacent first heat dissipation slots 211 on the cover plate 12, and/or the vertical sheet 1912 abuts against the part between two adjacent first heat dissipation slots 211 on the base 11. Through the above arrangement, the base 11 and the cover plate 12 can be respectively abutted against the upper side and the lower side of the vertical sheet 1912, so that the base 11 and the cover plate 12 can fix the vertical sheet 1912, thereby achieving the fixation of the first side heat dissipation fins 191.

In this embodiment, the transverse sheet 1911 separates the heat dissipation channel 1913 into an upper heat dissipation channel 1913a and a lower heat dissipation channel 1913b. The upper heat dissipation channel 1913a is located on the upper side of the lower heat dissipation channel 1913b. The upper heat dissipation channel 1913a is respectively connected to the yoke of the first iron core 131, the first arc groove 125 and the outside world, and the lower heat dissipation channel 1913b is respectively connected to the yoke of the first iron core 131, the third arc groove 115 and the outside world.

Through the above-mentioned arrangement, external cooling air can be transported to the yoke of the first core 131 through the upper heat dissipation channel 1913a, and then transported to the first arc-shaped groove 125 through the upper heat dissipation channel 1913a, and then transported to the outside from the first arc-shaped groove 125; and/or external cooling air can be transported to the first arc-shaped groove 125 through the upper heat dissipation channel 1913a, and then transported to the outside from the first arc-shaped groove 125.

In addition, through the above-mentioned arrangement, external cooling air can be transported to the yoke of the first core 131 through the lower heat dissipation channel 1913b, and then transported to the third arc groove 115 through the lower heat dissipation channel 1913b, and then transported to the outside from the third arc groove 115; and/or external cooling air can be transported to the third arc groove 115 through the lower heat dissipation channel 1913b, and then transported to the outside from the third arc groove 115.

It should be noted that the structure of the second side heat sink 192 is consistent with the structure of the first side heat sink 191, so the way in which the second side heat sink 192 is connected to the base 11 and the cover 12 is consistent with the way in which the first side heat sink 191 is connected to the base 11 and the cover 12, the positional relationship between the second side heat sink 192 and the second heat dissipation groove 212 is a first positional relationship, and the positional relationship between the first side heat sink 191 and the first heat dissipation groove 211 is a second positional relationship, the first positional relationship is consistent with the second positional relationship, and this application will not go into details.

As shown in FIGS. 13 and 14 , as an implementation, the ratio of the thickness Q1 of the vertical sheet 1912 along the front-to-back direction of the induction electromagnetic pump 100 to the distance Q2 between two adjacent first heat dissipation slots 211 along the front-to-back direction of the induction electromagnetic pump 100 is greater than or equal to 0.6 and less than or equal to 1. Specifically, the ratio of the thickness Q1 of the vertical sheet 1912 along the front-to-back direction of the induction electromagnetic pump 100 to the distance Q2 between two adjacent first heat dissipation slots 211 along the front-to-back direction of the induction electromagnetic pump 100 is greater than or equal to 0.7 and less than or equal to 0.9. Through the above-mentioned arrangement, it is possible to avoid the thickness Q1 of the vertical sheet 1912 being too large, which would cause the vertical sheet 1912 to block the first heat dissipation slot 211, thereby increasing the flow rate of external cooling air and further improving the heat dissipation efficiency of the induction electromagnetic pump 100; it is also possible to avoid the thickness Q1 of the vertical sheet 1912 being too small, which would cause the strength of the vertical sheet 1912 to be unable to meet the requirements, thereby avoiding the deformation of the first side heat sink 191 due to insufficient strength of the first side heat sink 191, and further increasing the flow rate of external cooling air while meeting the use strength of the first side heat sink 191 to improve the heat dissipation efficiency of the induction electromagnetic pump 100.

In the present application, since the first iron core 131 and the second iron core 132 are also respectively abutted and connected to the left and right sides of the flow channel 15, the total width of the first side heat sink 191, the first iron core 131, the flow channel 15, the second iron core 132, and the second side heat sink 192 along the left and right direction of the induction electromagnetic pump 100 can be the overall width S1 (refer to FIG. 5), the width of the base 11 or the cover plate 12 is the pump body width S2, and the ratio of the overall width S1 to the pump body width S2 is greater than or equal to 0.8 and less than or equal to 1. Specifically, the ratio of the overall width S1 to the pump body width S2 is 0.9. Through the above-mentioned arrangement, it is possible to avoid the first side heat sink 191, the yoke of the first core 131, the yoke of the second core 132, and the second side heat sink 192 from exceeding the base 11 and the cover plate 12, thereby avoiding the first heat sink 211 and the second heat sink 212 from being unable to dissipate heat for the first side heat sink 191, the yoke of the first core 131, the yoke of the second core 132, and the second side heat sink 192, thereby improving the heat dissipation efficiency of the induction electromagnetic pump 100; it is also possible to avoid the overall width S1 being too small, resulting in too low a space utilization rate between the base 11 and the cover plate 12, thereby improving the space utilization rate of the induction electromagnetic pump 100 and improving the structural compactness of the induction electromagnetic pump 100.

For example, in the present application, the materials of the first side heat sink 191 and the second side heat sink 192 can both be aluminum, so as to improve the thermal conductivity of the first side heat sink 191 and the second side heat sink 192 .

As shown in FIG15 , as an implementation method, the induction electromagnetic pump 100 further includes a top heat sink 22 and a fixing ring 23. The top heat sink 22 is located on the upper side of the cover plate 12 and is fixedly connected to the cover plate 12 through the fixing ring 23. The fixing ring 23 is fixedly connected to the upper side of the cover plate 12. The heat generated by the winding 14 is transferred to the core assembly 13, and is transferred to the top heat sink 22 through the cover plate 12 abutting against the core assembly 13, so that the heat is transferred to the outside through the top heat sink 22, that is, the top heat sink 22 can cooperate with the side heat sink assembly 19, thereby further improving the heat dissipation efficiency of the induction electromagnetic pump 100.

Specifically, the induction electromagnetic pump 100 includes a fastener 16 and a connector 17 that cooperates with the fastener 16. The fastener 16 is passed through the fixing ring 23, the cover plate 12, the core assembly 13 and the base 11 and is fixed by the connector 17, so that the fixing ring 23, the cover plate 12, the core assembly 13 and the base 11 can be connected by the same fastener 16 to simplify the connection structure of the fixing ring 23, the cover plate 12, the core assembly 13 and the base 11, thereby simplifying the structure of the induction electromagnetic pump 100 to improve the structural compactness of the induction electromagnetic pump 100.

More specifically, the fixing ring 23 at least partially extends downward to form a plurality of fixing portions 231 , which extend substantially in an “L” shape. The fasteners 16 are passed through the fixing portions 231 , the cover plate 12 , the core assembly 13 and the base 11 and are fixed thereto via the connectors 17 .

As an implementation method, the top heat sink 22 includes a first sheet 221 extending along a first plane and a plurality of second sheets 222 extending along a second plane, the first sheet 221 and the second sheet 222 are integrally formed, the first plane is perpendicular to the left and right direction of the induction electromagnetic pump 100, and the second plane is perpendicular to the front and rear direction of the induction electromagnetic pump 100. Among them, the second sheet 222 and the inner side surfaces on the left and right sides of the fixing ring 23 are interference fit; the first sheet 221 and the inner side surfaces on the front and rear sides of the fixing ring 23 are interference fit. Through the above arrangement, the position of the top heat sink 22 can be limited by the fixing ring 23, so that the operation of the top heat sink 22 is more stable.

Specifically, a cooling channel 223 is formed between two adjacent second sheets 222, and the cooling channel 223 is connected to the outside and the upper surface of the cover plate 12, so that the external cooling air delivered to the top heat sink 22 is delivered to the upper surface of the cover plate 12 through the cooling channel 223, and then delivered to the outside through the gap between the fixing ring 23 and the upper surface of the cover plate 12. In particular, since the fixing ring 23 at least partially extends downward to form a fixing portion 231, the fixing portion 231 can make a gap between the fixing ring 23 and the upper surface of the cover plate 12, so that the external cooling air can be delivered to the outside through the gap between the fixing ring 23 and the upper surface of the cover plate 12.

In this embodiment, when observing the induction electromagnetic pump 100 from top to bottom, the top heat sink 22 and the first slot body 111 at least partially overlap, and the top heat sink 22 and the second slot body 121 at least partially overlap, so that the heat generated by the winding 14 can be transferred to the top heat sink 22 through the cover plate 12 after being transferred to the core assembly 13, and then the heat dissipation effect of the induction electromagnetic pump 100 is further improved through the cooperation of the top heat sink 22 and the side heat dissipation assembly 19.

For example, in the present application, the material of the top heat sink 22 may be aluminum, so as to improve the thermal conductivity of the top heat sink 22 ; the material of the fixing ring 23 may be aluminum or plastic.
