For example, the connection can be fixed connection, detachable connection or integral connection; can be mechanically or electrically connected; the connection may be direct, indirect via an intermediate medium, or communication between two elements, or only surface contact. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

In the present embodiment, the heat exchange module 100 is disposed in the accommodating space 22, and the heat exchange module 100 may include the mounting frame 10, the heat exchange core 30, and the spray assembly 50. The mounting frame 10 may be fixedly coupled within the housing 20, and the mounting frame 10 is provided with a placement port 12, the placement port 12 being positioned opposite the mounting port 212. The heat exchange core 30 is detachably accommodated in the installation frame 10 through the placement port 12. The spray assembly 50 may be fixedly coupled to the outside of the mounting frame 10 and located on one side of the heat exchange core 30. The heat exchange core 30 is separated from the spray assembly 50 when detached from the mounting frame 10.

When assembling, the door 25 is opened to expose the mounting opening 212, and then the heat exchange core 30 is lifted by a lifting tool, moved to the position of the mounting opening 212 and aligned with the placement opening 12. The heat exchange core 30 is embedded into a part of the installation frame 10 through the placement opening 12, and then the hoisting tool is removed, so that the heat exchange core 30 is completely pushed into the installation frame 10. Finally, the door 25 is closed, and the assembly is completed. The spray assembly 50 is fixed outside the installation frame 10 and is not directly connected with the heat exchange core 30, if the heat exchange core 30 needs to be maintained and replaced, the heat exchange core 30 can be directly pulled out of the installation frame 10, the spray assembly 50 and other structures cannot be affected, the maintenance cost is reduced, and the convenience of maintenance and replacement is improved.

In the present embodiment, the heat exchange core 30 is installed in the case 20 through the installation frame 10, for heat exchanging the gas flowing therethrough. The heat exchange core 30 is based on the principle that two groups of mutually-intersected and non-communicated air channels are arranged on one heat exchange body, and the air in the two air channels exchanges heat when passing through the heat exchange body. The heat exchange core 30 may be provided with an inner circulation air inlet, an inner circulation air outlet, an outer circulation air inlet and an outer circulation air outlet. In this embodiment, the heat exchange core 30 is generally rectangular and block, so as to reduce the air duct and improve the heat exchange efficiency, the heat exchange core 30 may have different installation schemes according to the positions of the air duct and other elements, for example, the heat exchange core 30 may be installed in a forward direction, that is, the end face of the heat exchange core 30 is generally parallel to the bottom wall 23 when installed, or the heat exchange core 30 may be installed in a diamond shape, that is, the end face of the heat exchange core 30 intersects with the bottom wall 23 when installed, and the end face of the heat exchange core 30 is diamond-shaped when viewed from one side of the cooling unit 200 after the installation is completed.

Referring to fig. 4 and 5, in the present embodiment, the mounting frame 10 may be fixedly connected to the housing 20 for mounting the heat exchange core 30 and acting as a centering element to provide an indirect connection between the heat exchange core 30 and other structures. The mounting frame 10 may include a mounting bracket 14 and a support bracket 16. The mounting frame 14 is provided with a mounting space 11 for accommodating the heat core 30, and the mounting space 11 penetrates through one end of the mounting frame 14 to form the above-mentioned placement opening 12. The mounting frame 14 is in a hollow frame design, so that a plurality of positions of the mounting space 11 are communicated with the outside, and the heat exchange core 30 in the mounting space 11 is matched with other structures of the cooling unit 200 conveniently. The support bracket 16 is connected between the mounting bracket 14 and the inner wall of the case 20.

For the heat exchange core 30 according to different installation schemes of the positions of the air duct and other elements, the specific structure and the installation mode of the installation frame 10 are different, and as an example, the heat exchange core 30 adopts a diamond installation scheme, and then the installation frame 14 is a cubic frame with a diamond end face. In particular, in this embodiment, the mounting frame 14 is a hollowed diamond frame that conforms to the shape of the heat exchange core 30. The placement opening 12 on the diamond-shaped frame 14 is defined by four edges joined end to end such that the placement opening 12 appears as a diamond with the placement opening 12 at one end of the frame 14. The mounting frame 14 is provided with an inner diameter of one end of the placement port 12 greater than or equal to an outer dimension of one end of the heat exchange core 30 so that the heat exchange core 30 can pass through the placement port 12. The opening direction of the placement opening 12 is approximately parallel to the bottom wall 23, the placement opening 12 can be regarded as a closed annular structure, the normal line of the plane of the closed annular structure represents the opening direction of the placement opening 12, and when the heat exchange core 30 is assembled and disassembled, the heat exchange core 30 is only pushed along the opening direction, so that the operation process is convenient and quick.

Further, the mounting frame 14 has two adjacent bearing sides 141, one end of each of the two bearing sides 141 being connected to each other and being substantially perpendicular to each other to collectively define a bottom corner 143 of the mounting frame 14. The sharp corner of the bottom corner 143 is located on the side of the mounting bracket 14 facing the bottom wall 23, and the opening of the bottom corner 143 is facing the heat exchange core 30. When the heat exchange core 30 is installed in the installation frame 14, the bottom corner of the heat exchange core 30 facing the bottom wall 23 is placed in the bottom corner 143, and two adjacent end faces of the heat exchange core 30, which are close to the bottom wall 23, are respectively abutted against and placed on the two bearing sides 141.

Because the mounting frame 14 is a hollowed diamond frame conforming to the shape of the heat exchange core 30, in order to prevent the heat exchange core 30 from separating from the mounting frame 14 from the rest of the hollowed parts of the mounting frame 14, which are not provided with the openings 12, the mounting frame 10 may further include a limit bar 145, where the limit bar 145 is disposed on an end surface of the mounting frame 14. Except for one surface provided with the placement opening 12, the mounting frame 14 can be provided with limiting strips 145 on the other five surfaces so as to limit the position of the heat exchange core 30, so that the heat exchange core 30 is prevented from being separated from the mounting frame 14 from the position except for the placement opening 12, and the mounting stability of the heat exchange core 30 is improved. The limiting bars 145 are disposed at positions of the mounting frame 14 near the corners to reduce the influence on the cooperation of the heat exchange core 30 and other elements outside the mounting frame 10, for example, each corner of the mounting frame 14 corresponds to two limiting bars 145, and the two limiting bars 145 are respectively located at two sides of the corresponding corner.

A support bracket 16 is attached to the mounting bracket 14, the support bracket 16 being adapted to connect the mounting bracket 14 to the housing 20. The position where the support frame 16 is attached to the inner wall of the case 20 is not limited in this specification, and for example, the support frame 16 may be attached to the side wall 21 or may be attached to the bottom wall 23. In this embodiment, the support bracket 16 is attached to the bearing side 141 of the mounting bracket 14 and is fixedly attached to the bottom wall 23. In order to further improve the stability of the connection between the mounting frame 14 and the bottom wall 23, two support frames 16 are provided, and the two support frames 16 are respectively connected to the two bearing sides 141 and are respectively located at two opposite sides of the bottom corner 143.

The two support frames 16 are disposed substantially symmetrically about the bottom corner 143, and the support frame 16 on one bearing side 141 is described as an example, where the support frame 16 includes two support members 161, and the two support members 161 are respectively located on a side of the bearing side 141 near the mounting opening 212 and a side of the bearing side 141 far from the mounting opening 212. The support 161 may include a first support bar 1612 and a second support bar 1614, one end of the first support bar 1612 may be fixedly connected to the mounting bracket 14 and the other end may be fixedly connected to the bottom wall 23, the first support bar 1612 being disposed generally perpendicular to the bottom wall 23. One end of the second support bar 1614 is connected to the mounting frame 14 and is spaced from the connection point of the first support bar 1612 on the mounting frame 14, and the other end of the second support bar 1614 is connected to the bottom wall 23 and is close to the connection point of the first support bar 1612 on the bottom wall 23. The second support bar 1614 is inclined relative to the first support bar 1612, and the frames formed by the second support bar 1614, the first support bar 1612 and the support side 141 together form a triangle-like structure, so that the stability of the mounting rack 14 is improved.

In this application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless explicitly defined otherwise.

To further provide support to the mounting frame 14, in this embodiment, the mounting frame 10 may also include a support base 18. The support base 18 is connected to the case 20, and in particular, the support base 18 may be fixedly connected to the bottom wall 23. The limit groove 181 has been seted up to the one side of supporting seat 18 facing away from diapire 23, and limit groove 181 is the V type groove, and supporting seat 18 sets up between mounting bracket 14 and diapire 23. The mounting frame 14 is placed on the supporting seat 18, the bottom corner 143 is embedded in the limiting groove 181, and the portions, close to the bottom corner 143, of the two bearing sides 141 are respectively abutted against the two side walls of the limiting groove 181. The supporting seat 18 cooperates with the supporting frame 16 to support the mounting frame 14, and the limiting grooves 181 increase the contact area between the supporting seat 18 and the mounting frame 14, so that the supporting force and the stability are improved, and meanwhile, the damage to the mounting frame 14 is reduced.

During assembly, the supporting seat 18 is fixed on the bottom wall 23, the mounting frame 14 is erected on the supporting seat 18, and the supporting frame 16 is fixed on the bottom wall 23. When the heat exchange core 30 is installed, the heat exchange core 30 is lifted up by adopting a lifting tool in a diamond-shaped assembly mode, aligned with the placement opening 12, and then the heat exchange core 30 is pushed to enable a part of the heat exchange core 30 to enter the installation space 11, as shown in fig. 6. The lifting tool is removed and the heat exchange core 30 is pushed completely into the mounting frame 14. The spray assembly 50 and other structures may be fixed to the mounting frame 10 in advance, or may be fixed to the mounting frame 10 after the heat exchange core 30 is mounted to the mounting frame 10. Finally, the door body 25 is closed, and the assembly is completed.

When maintenance and replacement are required, the door 25 is opened, and then the heat exchange core 30 is pulled out of a part of the mounting frame 14 from the placement port 12 by a tool. A supporting tool car or other supporting tool is placed below the heat exchange core 30, and the heat exchange core is installed back in the mode after maintenance and replacement. The heat exchange core 30 is simple to install and detach, and convenient to maintain and replace.

In the description of the present application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "inner," and the like indicate orientation or positional relationships based on those shown in the drawings, and are merely used for simplifying the description of the present application, rather than indicating or implying that the apparatus or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application.

Referring to fig. 7 and 8, as another example, the heat exchange core 30 adopts a forward mounting scheme, and the mounting frame 14 is a rectangular frame. In this embodiment, the mounting frame 14 is a rectangular hollow frame that matches the shape of the heat exchange core 30. The placement opening 12 on the mounting frame 14 having a rectangular frame is defined by four edges connected end to end so that the placement opening 12 is rectangular, and the placement opening 12 is located at one end of the mounting frame 14. The mounting frame 14 is provided with an inner diameter of one end of the placement port 12 greater than or equal to an outer dimension of one end of the heat exchange core 30 so that the heat exchange core 30 can pass through the placement port 12. The opening direction of the placement opening 12 is approximately parallel to the bottom wall 23, the placement opening 12 can be regarded as a closed annular structure, the normal line of the plane of the closed annular structure represents the opening direction of the placement opening 12, and when the heat exchange core 30 is assembled and disassembled, the heat exchange core 30 is only pushed along the opening direction, so that the operation process is convenient and quick.

The mounting frame 14 is placed on the bottom wall 23 with its end face abutting against the bottom wall 23 and being fixedly connected to the bottom wall 23. Similar to the mounting frame 10 in the diamond mounting scheme, the mounting frame 10 may also include a limit bar 145, the limit bar 145 being disposed on an end surface of the mounting frame 14. Except for one surface provided with the placement opening 12, the mounting frame 14 can be provided with limiting strips 145 on the other five surfaces so as to limit the position of the heat exchange core 30, so that the heat exchange core 30 is prevented from being separated from the mounting frame 14 from the position except for the placement opening 12, and the mounting stability of the heat exchange core 30 is improved. Similarly, the limiting bars 145 are also disposed on the mounting frame 14 near each corner to reduce the influence on the cooperation of the heat exchange core 30 with other elements outside the mounting frame 10, for example, each corner of the mounting frame 14 corresponds to two limiting bars 145, and the two limiting bars 145 are respectively located at two sides of the corresponding corner.

In the present embodiment, the supporting frame 16 is connected to two sides of the mounting frame 14 and is connected to the end surface of the mounting frame 14 contacting the bottom wall 23. Similar to the diamond-shaped mounting embodiment, two support brackets 16 are provided, each support bracket 16 including two support members 161, and four support members 161 are respectively disposed at four corners of the bottom wall 23 of the mounting bracket 14. In this embodiment, the first support bar 1612 is connected to the bottom end of the mounting frame 14 and is disposed to be attached to the bottom wall 23. One end of the second support bar 1614 is connected to one side of the mounting frame 14, the other end is connected to the first support bar 1612, and the second support bar 1614 is obliquely arranged relative to the first support bar 1612. The first support bar 1612, the second support bar 1614 and the vertical frame of the mounting rack 14 together form a support structure similar to a triangle, so that the mounting stability of the mounting rack 14 is improved.

When assembled, the mounting bracket 14 and the support bracket 16 are first secured to the bottom wall 23. When the heat exchange core 30 is installed, the heat exchange core 30 is lifted up by a lifting tool in a forward assembly mode, aligned with the placement opening 12, and then the heat exchange core 30 is pushed to enable a part of the heat exchange core 30 to enter the installation space 11, as shown in fig. 9. The lifting tool is removed and the heat exchange core 30 is pushed fully into the mounting frame 14 as shown in fig. 10. When maintenance and replacement are required, the door 25 is opened, and then the heat exchange core 30 is pulled out of a part of the mounting frame 14 from the placement port 12 by a tool. A supporting tool car or other supporting tool is placed below the heat exchange core 30, and the heat exchange core is installed back in the mode after maintenance and replacement. The heat exchange core 30 is simple to install and detach, and convenient to maintain and replace.

In this embodiment, the spray assembly 50 is fixedly attached to the outside of the mounting frame 10 for spraying the heat exchange core 30.
