While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The words "exemplary" and "such as" are used herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" and "for example" is not necessarily to be construed as superior or better than other embodiments.

In addition, in order to better illustrate the present application, numerous specific details are given in the following specific examples. It will be understood by those skilled in the art that the present application may be practiced without certain of the specific details. In some instances, methods, means, components and circuits well known to those skilled in the art have not been described in detail in order to highlight the gist of the present application.

Taking the heat exchange core used in the indirect evaporative cooling unit as an example, the sealing device S according to the present application is introduced with reference to Fig. 1 to Fig. 13 .

Referring to FIG. 1 , the indirect evaporative cooling unit includes one or more (usually multiple) heat exchange cores C. Each heat exchange core C is, for example, a substantially cuboid structure. A plurality of heat exchange cores C are fixed by the frame F and arranged in an array. There are multiple intersecting channels distributed inside the heat exchange core C. After the two fluids with different temperatures are introduced into the heat exchange core C, they can flow along their respective channels, and the two air streams will not directly contact each other in the heat exchange core C. . Each of the two air streams realizes heat exchange by exchanging heat with the heat exchange core C.

In the working state, the heat exchange core C is clamped (for example, clamped in the second direction D2 shown in FIG. 1 ) to the frame F by the sealing device S.

In the state of maintenance (including inspection and replacement), the sealing device S releases the heat exchange core C, and the heat exchange core C can be taken out from the frame F along the first direction D1 shown in FIG. 1 by pushing and pulling.

(first embodiment)

Referring to Fig. 2 to Fig. 8, the sealing device S according to the first embodiment of the present application is introduced.

In this embodiment, the sealing device S includes a main body 10 , a fixing member 20 , a hinge 30 , a first pin 40 , a spring 50 and a second pin 60 .

The fixing part 20 is used for fixed connection with the frame F. For the convenience of description below, sometimes the fixing part 20 and the frame F are not particularly distinguished.

The hinge 30 rotatably connects the main body 10 to the fixture 20 (ie, the frame F). Referring to FIG. 2 , the main body 10 can rotate (or swing) relative to the fixing member 20 in the direction indicated by the arrow ω in the figure.

The main body 10 is elongated and extends along a first direction D1 , and the heat exchange core C is disposed adjacent to the main body 10 in a second direction D2 perpendicular to the first direction D1 . When the main body 10 swings along the arrow ω, the upper end of the main body 10 in FIG. 2 is displaced in the second direction D2, so that the main body 10 can clamp or loosen the heat exchange core C in the second direction D2.

For example, it is defined that when the main body 10 swings to the first position, the heat exchange core C is in the (being) clamped state; when the main body 10 is defined to swing to the second position, the heat exchange core C is in the (being) loosened state.

When the heat exchange core C is in a clamped state, the first pin 40 and the second pin 60 are in a locked state; when the heat exchange core C is in a loose state, the first pin 40 and the second pin 60 are in an unlocked state.

Next, referring to FIG. 3 to FIG. 8 , the locking manner of the main body 10 by the first pin 40 and the second pin 60 will be described in detail.

The through holes (also referred to as the first through holes of the main body) on the plurality of mounting parts 100 are arranged along the first direction D1, and the first pin 40 passes through the through holes on these mounting parts 100 to be able to reciprocate in the first direction D1 The mobile way is installed on the main body 10 . The installation part 100 provides a guide for the movement of the first pin 40 in the first direction D1.

It should be understood that the present application does not limit the specific arrangement of the installation part 100 , and it can also be said that the main body 10 is sleeved on the outer periphery of the first pin 40 through the installation part 100 .

In the first direction D1, the length of the first pin 40 is greater than the length of the main body 10 . Both ends of the first pin 40 are respectively formed as a first pin head 41 and a first pin tail 42 , the first pin head 41 serves as an operating end, and the first pin tail 42 serves as a locking end.

The fixing part 20 includes a first fixing part 21 and a second fixing part 22 . In the first direction D1 , the first fixing part 21 is disposed close to the first pin tail 42 , and the second fixing part 22 is disposed close to the first pin head 41 (see FIG. 4 and FIG. 5 ).

Referring to Fig. 3 and Fig. 6 at the same time, a first pin hole 21a is formed on the first fixing member 21, and when the main body 10 swings to the first position, the first pin hole 21a and the through hole on the mounting part 100 are aligned along the first direction D1. alignment. In this state, the first pin tail portion 42 can pass through the first pin hole 21a, thereby locking the main body 10 at the first position. The position of the first pin 40 at this time is also called the first working position of the first pin 40 .

In order to ensure the secure locking of the first pin 40 and facilitate the operation of the first pin 40, a spring 50 is provided on the outer circumference of the first pin 40. Two ends of the spring 50 are respectively connected to the first pin 40 and the main body 10 . When the first pin 40 is in the locked state, the spring 50 exerts a pushing force (preload) on the first pin 40 toward the first fixing member 21 , so that the first pin 40 maintains a state of passing through the first pin hole 21 a.

In the case that the first pin 40 needs to be unlocked, the first pin head 41 can be pulled in the direction indicated by the hollow arrow in FIG. . The position of the first pin 40 at this time is also called the second working position of the first pin 40 .

It should be understood that during the process of switching the first pin 40 from the second working position to the first working position, the spring 50 can play the role of making the first pin tail 42 rebound automatically.

Referring to FIG. 5 and FIG. 7 simultaneously, the second pin 60 is mounted on the end of the main body 10 close to the first pin head 41 . The first pin 40 and the second pin 60 respectively play a locking role on the main body 10 at two ends of the main body 10 .

The second pin 60 extends vertically with respect to the first direction D1 , and the second pin 60 is connected to the main body 10 through a second body through hole formed in the main body 10 . The second pin 60 includes a second pin head 61 as an operating end and a second pin tail 62 as a locking end. The second pin tail portion 62 can pass through the second pin hole 22 a formed in the second fixing member 22 .

Optionally, the second pin 60 is a spring pin, and the second pin tail 62 protrudes through the second pin hole 22a in a natural state. At this time, the second pin 60 is in a locked state, and the main body 10 abuts against the heat exchange core c.

When the second pin 60 needs to be unlocked, the second pin tail 62 can be disengaged from the second pin hole 22 a by pulling the second pin head 61 .

Optionally, referring to FIG. 8 , the main body 10 is in the shape of a semi-closed sleeve, which includes a bottom plate 111 , an inner plate 112 , an outer plate 113 and an upper plate 114 . The bottom plate 111 is in the shape of a strip. In the second direction D2, the inner plate 112 is arranged on the end of the bottom plate 111 close to the heat exchange core C (not shown in FIG. 8 ), and the outer plate 113 is arranged on the end of the bottom plate 111 away from the heat exchange core C. The upper board 114 is connected to the inner board 112 , and the upper board 114 is opposite to the bottom board 111 . Thus, a semi-enclosed space is surrounded by the bottom plate 111 , the inner plate 112 , the outer plate 113 and the upper plate 114 . The mounting part 100 and the first pin 40 are disposed in the semi-enclosed space.

Optionally, the main body 10 further includes a sealing strip 10s. The sealing strip 10s is installed on the surface of the inner panel 112 facing the heat exchange core C in the second direction D2. The sealing strip 10s has the effect of strengthening the sealing effect between the main body 10 and the heat exchange core C. That is, the main body 10 can press the sealing strip 10s in the second direction D2 so that the sealing strip 10s is in close contact with the heat exchange core C. The sealing strip 10s is made of flexible material, for example, the sealing strip 10s is made of rubber or silica gel or fiber.

In the first direction D1, both the first pin head 41 and the second pin head 61 are located at the same end of the main body 10, which makes it very easy to operate the locking and unlocking of the main body 10. Especially for the main body 10 with a larger size in the first direction D1, it is not necessary to operate on two remote ends separately, but only need to operate on one end to control the locking state of both ends of the main body 10 .

It should be understood that since the first pin 40 and the second pin 60 both play a role in locking the position of the main body 10, in a possible modified embodiment, the second pin 60 can also be used at both ends of the main body 10 Or both use a structure similar to the first pin 40 .

(second embodiment)

Next, referring to FIGS. 9 to 13 , a sealing device S according to a second embodiment of the present application will be introduced. The second embodiment is a modification of the first embodiment, and for features identical or similar to those of the first embodiment, the same reference numerals are used in this embodiment, and detailed descriptions of these features are omitted.

In this embodiment, the clamping and loosening of the heat exchange core C by the main body 10 is not realized by the rotation of the main body 10 relative to the fixing part 20 (or the frame F), but by the rotation of the main body 10 relative to the fixing part 20. The reciprocating motion in the second direction D2 is realized.

In this embodiment, the sealing device S includes a main body 10 , a fixing member 20 , a rotating shaft 300 , a guide block 400 , a positioning block 500 , and a connecting member 600 .

The main body 10 includes an inner side panel 112 and a plurality of mounting parts 100 . The mounting portion 100 is disposed on a side of the inner plate 112 away from the heat exchanging core C. The rotating shaft 300 passes through the through holes of the plurality of mounting parts 100 , or the mounting part 100 is sheathed on the rotating shaft 300 . The rotating shaft 300 can rotate around its own axis relative to the main body 10 .

The guide block 400 is in the shape of a cam, and the guide block 400 is connected to the rotating shaft 300 in a non-rotatable manner.

Referring to FIG. 9 and FIG. 13 simultaneously, the fixing member 20 includes a fixing guide 200 . The fixing guide 200 is in the shape of a bracket, which includes a stop wall 201 and a guide wall 202 . The stopper wall 201 is used to provide abutting foundation for the guide block 400 , and the guide wall 202 is used to provide support and guide for the reciprocating movement of the rotating shaft 300 .

Optionally, both axial ends of the rotating shaft 300 are provided with fixed guides 200 .

The guide wall 202 is formed with a guide groove 200a extending along the second direction D2. Optionally, the guide groove 200a is formed in the shape of a long waist hole. The rotating shaft 300 passes through the guide groove 200a, and the guiding groove 200a limits the movement of the rotating shaft 300, so that (without considering the translation of the rotating shaft 300 along the first direction D1) the rotating shaft 300 can only rotate around its own axis and move along the guide. Translational movement of the slot 200a (ie, in the second direction D2).

Optionally, in order to limit the translational movement of the rotating shaft 300 along its own axis (along the first direction D1), for example, the installation part 100 and the guide wall 202 can be respectively provided on both axial sides of the guide block 400 and very close to the guide block 400 , so that the installation part 100 and the guide wall 202 can limit the rotating shaft connected to the guide block 400 in the first direction D1.

Optionally, the guide slot 200a has an opening facing the main body 10, so as to facilitate inserting the rotating shaft 300 into the guide slot 200a along the second direction D2.

In the second direction D2 , the stop wall 201 is disposed on a side of the rotating shaft 300 away from the main body 10 . The guide block 400 abuts against the stopper wall 201 . Since the guide block 400 is in the shape of a cam, during the rotation process of the guide block 400 with the rotating shaft 300, in the second direction D2, the distance between the center of the rotating shaft 300 and the stop wall 201 will change; correspondingly, the main body 10 The distance from the heat exchange core C in the second direction D2 will change, so as to achieve clamping and loosening of the heat exchange core C by the main body 10 .

Optionally, referring to FIG. 12 , the abutting surface 401 of the guide block 400 for contacting the stop wall 201 is involute in a section perpendicular to the first direction D1 . This enables smooth rotation of the guide block 400 relative to the stopper wall 201 .

It is defined that when the main body 10 moves to the first position in the second direction D2, the heat exchange core C is in a clamped state; when the main body 10 moves to a second position, the heat exchange core C is in a loose state.

Optionally, when the main body 10 moves to the first position, the positioning block 500 is fixedly connected to the guide member 200, and the rotating shaft 300 cannot move in the second direction D2 at this moment. Therefore, the rotating shaft 300 , the positioning block 500 , the guide block 400 and the main body 10 are all fixed at the first position, and the heat exchange core C is kept clamped. Specifically, for example, the positioning block 500 is formed with a through hole 500a, and the guide wall 202 is formed with a positioning hole 200b (such as a threaded hole), and a connecting member 600 (such as a screw) is used to pass through the through hole 500a and connect to the positioning hole 200b.

Optionally, the two ends of the rotating shaft 300 in the first direction D1 are formed with a hexagonal head-shaped rotating shaft end 301, and the rotating shaft end 301 can cooperate with, for example, a wrench, so that the rotating shaft 3 can be pulled (turned) using a wrench .

When the clamping state of the heat exchange core C needs to be adjusted, the connection between the positioning block 500 and the guide member 200 is loosened. Then the rotating shaft 300 is rotated, and as the contact point between the guide block 400 and the stopper wall 201 changes, the rotating shaft 300 moves along the second direction D2 under the guidance of the guide groove 200a, and the clamping state of the main body 10 to the heat exchange core C occurs. Variety.

It should be understood that at least one of the guide block 400 and the positioning block 500 may be integrally formed with the rotating shaft 300 .

It should be understood that the sealing device of the present application can be installed on both sides of the heat exchange core C in the second direction D2; it can also be installed on only one side of the heat exchange core C, and use the fixed frame F as a pair on the other side pieces.

It should be understood that the present application also provides an indirect evaporative cooling unit including the sealing device S.

It should be understood that, in addition to being used in the indirect evaporative cooling unit to seal the heat exchange core C, the sealing device according to the present invention can also be used to seal other structures (also called sealed parts) that require pulling maintenance, such as but not Restricted to: Fan modules and filter modules in indirect evaporative cooling units.

The present application has at least one of the following advantages:

(i) The sealing device of the present application can be moved conveniently relative to the sealed part, and while realizing the sealing of the sealed part, it also takes into account the requirement that the sealed part needs to be maintained by, for example, pulling.

(ii) The inner side of the main body 10 is provided with a sealing strip 10s, which can achieve a good seal by squeezing the sealing strip 10s through the main body 10, avoiding the setting of fasteners such as screws on the sealed parts, especially for the heat exchange core, effectively avoiding the The problem of small space and difficult operation for screwing the heat exchange core in high-position operation also avoids the disadvantage of repeated disassembly and assembly of fasteners to damage the original sealing performance, and further improves the sealing effect.
