In this embodiment, as shown in fig. 4, the fifth extending portion 33 is formed by horizontally extending one side of the first housing 31 and the second housing 32. The sixth extension portion 34 is formed by extending the other side of the first housing 31 and the second housing 32 in parallel to the direction of the fifth extension portion 33 (which may also be formed by bending), and then the first housing 31 is placed in a right L shape, and the second housing 32 is placed in an upside-down L shape, so that the first housing 31 and the second housing 32 form a complete rectangular housing 3. At the joint position of the first casing 31 and the second casing 32, the sixth extending portion 34 and the fifth extending portion 33 are overlapped, and when the casing 3 is viewed from the inside to the outside, the sixth extending portion 34 is located outside the fifth extending portion 33, that is, the inner wall surface of the sixth extending portion 34 is attached to the outer wall surface of the fifth extending portion 33. The structure can reduce the assembly difficulty of the first shell 31 and the second shell 32, increase the welding area and improve the strength of the first shell 31 and the second shell 32 after welding.

Alternatively, the flange 35 may not be provided at the position where the fifth extension 33 and the sixth extension 34 are provided, so that the two are brazed when they are overlapped.

It will be understood, of course, that the first and

second housings

31 and 32 may also be configured in a generally C-shaped configuration assembled in the same manner as the first and

second housings

31 and 32 of the L-shaped configuration. The first housing 31 and the second housing 32 may have different shapes and structures, and only the two housings can be spliced to form one housing 3.

The housing 3 is provided with at least one set of oppositely arranged inlets (not shown) and outlets (not shown), the number of inlets and outlets being the same. It can be that the first shell 31 is provided with an inlet, and the second shell 32 is correspondingly provided with an outlet; the first shell 31 can be provided with an outlet, and the second shell 32 can be correspondingly provided with an inlet; the first housing 31 may be provided with an inlet and an outlet; the second casing 32 may be provided with an inlet and an outlet at the same time, which does not limit the present application and does not affect the smooth flow and heat exchange effect of the first medium.

Each group of inlets and outlets are arranged corresponding to part of the flow channels, and the media flowing in the passages formed by the inlets and outlets of different groups are mutually independent. As shown in fig. 4, in the present embodiment, the housing 3 is provided with a set of oppositely arranged inlets and outlets, the inlets are arranged on the first housing 31, the outlets are arranged on the second housing 32, one inlet is communicated with all the flow channels, and one outlet is communicated with all the flow channels, the first medium flows into the housing 3 from the inlets, is distributed in the flow channels to exchange heat with the heat exchange tubes 41, and then flows out from the outlets. In other embodiments, the housing 3 is provided with at least two sets of inlets and outlets, which are oppositely arranged, and the at least two media may be the same or different, and it should be noted that the number of inlets and/or outlets of the first housing 31 is the same as the number of outlets and/or inlets of the second housing 32. I.e. the first housing 31 and the second housing 32 together form at least two sets of oppositely arranged inlets and outlets.

Referring to fig. 6, the inlet includes at least one fifth through hole 37, and the outlet includes at least one sixth through hole 38. The number of the fifth through holes 37 in the same group is the same as that of the sixth through holes 38 in the group, and each flow passage communicates with one fifth through hole 37 and one sixth through hole 38. Further, a passage through which the first medium flows is formed by the fifth through hole 37, the flow channel, and the sixth through hole 38. In the present embodiment, the fifth through hole 37 and the sixth through hole 38 may be rectangular holes, circular holes, elliptical holes, or holes having other shapes, and only need to be able to satisfy the circulation of the first medium and not to cause the first medium to flow.

It is to be understood that the inlet is adapted to leading the first medium into the housing and the outlet is adapted to leading the first medium out of the housing, and that, when there is only one fifth through hole 37, this fifth through hole 37 can be understood as an inlet, and when there are two or more fifth through holes 37, the two or more fifth through holes 37 together constitute an inlet; similarly, when there is only one sixth through hole 38, the sixth through hole 38 can be understood as an outlet, and when there are two or more sixth through holes 38, the two or more sixth through holes 38 together constitute the outlet.

Illustratively, the size and shape of the fifth through holes 37 of the inlets in the same group can be the same or different according to the requirement, and the size and shape of the sixth through holes 38 of the outlets in the same group can also be the same or different according to the requirement. Of course, the size and shape of the fifth through holes 37 of the inlets of different groups can be the same or different according to the requirement, and the size and shape of the sixth through holes 38 of the outlets of different groups can also be the same or different according to the requirement.

Further, the different sets of inlets and outlets and the corresponding flow channels may form different passages, such as one set of inlets and outlets, each of the fifth through holes 37 and the corresponding flow channel are communicated with each other through the sixth through hole 38 to form a flow path for the first medium to flow through, and the same set of inlets and outlets and the corresponding flow channels may form a plurality of flow paths, the plurality of flow paths forming a passage corresponding to the set of inlets. Correspondingly, the other sets of inlets and outlets and the corresponding flow channels also form further passages. In this embodiment, the different paths formed by the different sets of inlets and outlets may be used for the circulation of different temperatures and/or types of first media. Of course, different channels may also be provided for the circulation of the same temperature and/or type of first medium. However, the same set of inlets and outlets form a passage through which only the same temperature and/or type of first medium can flow.

Further, the widths of the fifth through hole 37 and the sixth through hole 38 in the vertical direction of the first housing 31 and/or the second housing 32 are not larger than the width of a single flow channel in the vertical direction, so that each fifth through hole 37 can be ensured to be communicated with only one flow channel. That is, the first medium flowing in through each fifth through hole 37 can all flow into the single flow passage communicating therewith, and finally flow out through the corresponding sixth through hole 38 without channeling into the other flow passages.

In addition, in the present embodiment, the several fifth through holes 37 of the inlets of different groups are distributed in a staggered manner along the height direction of the housing 3, and the several sixth through holes 38 of the outlets of different groups are distributed in a staggered manner along the height direction of the housing 3, that is, the several fifth through holes 37 and/or the several sixth through holes 38 of different groups on the first housing 31 are distributed in a staggered manner.

According to another embodiment of the shell 3 of the heat exchanger of the present application, the present embodiment is different from the above-mentioned embodiments in that the number and position of the inlet and the outlet on the shell 3 of the present embodiment are different, specifically, as shown in fig. 6 to 7, in the present embodiment, the first shell 31 is provided with two inlets, the inlets include a plurality of fifth through holes 37, and correspondingly, the second shell 32 is provided with two outlets, the outlets include a plurality of sixth through holes 38.

In the present embodiment, since two different sets of inlets are disposed on the first housing 31, the fifth through holes 37 of one set of inlets and the fifth through holes 37 of the other set of inlets are distributed in a staggered manner. Through the arrangement of the structure, the different flow channels communicated with any two groups of inlets can be ensured, wherein a channel for the first medium to flow is formed among the fifth through hole 37, the sixth through hole 38 and the corresponding flow channels, the channel can be used for carrying out temperature adjustment on a certain position, another channel for the first medium to flow is formed among the fifth through hole 37, the sixth through hole 38 and the corresponding flow channels, and the channel can be used for carrying out temperature adjustment on another position.

As shown in fig. 7, two sets of inlets are disposed on the first casing 31, and the fifth through holes 37 of the left inlet and the fifth through holes 37 of the right inlet are distributed in a staggered manner. The lower edge of the uppermost fifth through hole 37 in the left inlet is slightly higher than the upper edge of the right fifth through hole 37 or is in the same horizontal line, and the fifth through holes 37 of each group of inlets are uniformly distributed, so that the fifth through holes 37 of the left inlet and the fifth through holes 37 of the right inlet are distributed in a staggered manner, and the fact that the flow channels communicated by the two groups of inlets are different can be ensured.

As shown in fig. 8, three sets of inlets are provided on the first casing 31, and all the fifth through holes 37 of the three sets of inlets are distributed in a staggered manner. The lower edge of the uppermost fifth through hole 37 in the left inlet is slightly higher than the upper edge of the uppermost fifth through hole 37 in the middle inlet or is in the same horizontal line, then the lower edge of the uppermost fifth through hole 37 in the middle inlet is slightly higher than the upper edge of the uppermost fifth through hole 37 in the right inlet or is in the same horizontal line, and as the plurality of fifth through holes 37 of each group of inlets are uniformly distributed, all the fifth through holes 37 of the three groups of inlets can be distributed in a staggered manner, so that the different flow channels communicated by the three groups of inlets can be ensured.

Alternatively, the fifth through holes 37 in the same group are arranged at equal intervals, and the sixth through holes 38 in the same group are arranged at equal intervals. Because the fifth through hole 37 and the sixth through hole 38 are communicated with the circulation channel, and the circulation channel is formed between the heat exchange tubes 41, when the fifth through hole 37 is arranged at equal intervals and the sixth through hole 38 is arranged at equal intervals, the fifth through hole 37 and the sixth through hole 38 can ensure that the heat exchange tubes 41 are arranged at equal intervals, so that the heat exchange core 4 has enough structural strength and better pressure bearing performance. Moreover, the structure can ensure that the second medium in each heat exchange tube 41 can fully exchange heat with the first medium in the circulation channel, and the heat exchange effect is good.

Referring to fig. 4-6, the housing 3 of the present embodiment further includes a distribution box 5, the distribution box 5 is fixed to the housing 3, the distribution box 5 is provided with a receiving cavity 51, the receiving cavity 51 can cover at least one inlet or outlet, the first medium can enter into the receiving cavity 51 and enter into the inlet from the receiving cavity 51; or from the outlet into the receiving chamber 51 and finally out of the receiving chamber 51.

Taking the first housing 31 with two sets of inlets and the second housing 32 with two sets of outlets as an example, two distribution boxes 5 are disposed on the first housing 31 to cover the inlets (specifically, all the fifth through holes 37 of the inlets), and two distribution boxes 5 on the second housing 32 to cover the outlets (specifically, all the sixth through holes 38 of the outlets). Here, it should be understood that the distribution box 5 covers the inlet, and means that the upper end of the distribution box 5 is higher than the upper end of the inlet, the lower end of the distribution box 5 is lower than the lower end of the inlet, and the left end of the distribution box 5 exceeds the left end of the inlet and the right end of the distribution box 5 exceeds the right end of the inlet along the width direction of the distribution box 5. Similarly, the distribution box 5 covers the outlet, that is, the upper end of the distribution box 5 is higher than the upper end of the outlet and the lower end of the distribution box 5 is lower than the lower end of the outlet along the length direction of the distribution box 5, and the left end of the distribution box 5 exceeds the left end of the outlet and the right end of the distribution box 5 exceeds the right end of the outlet along the width direction of the distribution box 5. With the above arrangement, it is possible to ensure that the first medium enters the inlet through the fifth through hole 37 or the outlet through the sixth through hole 38 of the distribution box 5.

Alternatively, a plurality of accommodating cavities 51 may be provided in the distribution box 5, each accommodating cavity 51 may be communicated with one fifth through hole 37 of one inlet, or one sixth through hole 38 of one outlet, that is, the number of accommodating cavities 51 is the same as the number of fifth through holes 37 of each group of outlets, the first medium may enter the plurality of accommodating cavities 51 and enter the fifth through holes 37 from the accommodating cavities 51, or the first medium only enters the plurality of accommodating cavities 51 from the sixth through holes 38 and finally flows out from the accommodating cavities 51.

It is understood that when the housing 3 has more than 36 sets of inlets and outlets, one distribution box 5 may be disposed for each inlet and outlet, or a plurality of inlets may be covered by one distribution box 5, and a plurality of outlets may be covered by one distribution box 5, in which case the first medium in the accommodating chamber 51 of the distribution box 5 enters the plurality of inlets, and the first medium flowing out from the plurality of outlets converges in the accommodating chamber 51 of the distribution box 5 and flows out from the accommodating chamber 51.

In this embodiment, referring to fig. 5, the accommodating cavity 51 of the distribution box 5 may be formed by stamping an aluminum plate, and the accommodating cavity 51 is connected to a pipe orifice 52, and the pipe orifice 52 is used for being connected to a pipeline to realize the inflow or outflow of the first medium.

Optionally, a first positioning portion 53 is disposed at an edge of one side of the distribution box 5, and correspondingly, a second positioning portion 36 (shown in fig. 4) is disposed at a position on the housing 3 where the distribution box 5 is mounted, where the first positioning portion 53 can cooperate with the second positioning portion 36 to achieve positioning when the distribution box 5 is mounted, so as to reduce a problem of inclination when the distribution box 5 is mounted, and make mounting of the distribution box 5 simpler. In this embodiment, the first positioning portion 53 may be a semicircular opening or a circular hole, and correspondingly, the second positioning portion 36 may be a positioning column capable of being engaged with the semicircular opening or the circular hole. The first positioning portion 53 and the second positioning portion 36 may be grooves provided in the same direction, and at this time, the first positioning portion 53 is fitted in the second positioning portion 36, or the second positioning portion 36 is fitted in the first positioning portion 53, so that positioning at the time of mounting the distribution box 5 can be similarly achieved.

When the heat exchanger of the embodiment is used, a second medium firstly enters the first header 1, then enters the plurality of heat exchange tubes 41 through the first header 1, and flows into the second header 2 from the heat exchange tubes 41, and then flows out through the second header 2, at least one path of first medium (which may be the same in temperature and type, or different in temperature and type) flows into the accommodating cavity 51 of the distribution box 5 from the tube opening 5242 of the distribution box 5, then enters the flow channel through the inlet, exchanges heat with a second medium in the heat exchange tubes 41 in the flow channel, (meanwhile, the heat exchange effect between the first medium and the second medium is improved by the heat exchange fins 11), then enters the accommodating cavity 51 of the distribution box 5 through the outlet, and finally flows to a position where temperature adjustment is needed through the tube opening 5242 of the distribution box 5, so as to perform temperature adjustment.

The two outlets are distributed up and down in the vertical direction of the second housing 32, and the two outlets may be coaxially arranged (i.e. the distance from the two outlets to the same end of the second housing 32 is the same), or may be non-coaxially arranged (i.e. the distance from the two outlets to the same end of the second housing 32 is different, and the outlets are distributed left and right as shown in fig. 10). Each of the outlets has only one sixth through hole 38, and the sixth through hole 38 communicates with at least one of the flow channels.
