[0040] In some embodiments, there is a fixing plate 15 in the chassis 10 for fixing the heat exchanger 20. The support and fixing structure 30 includes a first support portion 31 and a first fixing portion 33 connected to each other. The first fixing portion 33 is connected to the fixing plate 15, and the first support portion 31 and the first fixing portion 33 are disposed at an obtuse angle; the heat exchanger 20 is disposed parallel to the first support portion 31, and the heat exchanger 20 is connected to the first support portion 31 through a connecting component.

[0041] Furthermore, to enhance stability, the support and fixing structure 30 further includes a second support portion 32 and a second fixing portion 34 connected to each other. The second fixing portion 34 is connected to the fixing plate 15, and the first support portion 31 and the second support portion 32 are connected to form a structure with a V-shaped cross section.

[0042] Specifically, the fixed plate 15 can be a middle partition plate. The middle partition plate is disposed between the first side plate 11 and the third side plate 13, and is parallel to the second side plate 12 and the fourth side plate 14. It can divide the accommodation space of the chassis 10 into a first accommodation cavity 10a and a second accommodation cavity 10b.

[0043] In some embodiments, the heat exchanger 20 can be disposed in the first accommodation cavity 10a. The heat exchanger 20 can be arranged at a first set angle with the fixed plate 15. Specifically, the heat exchanger 20 can be installed in the first accommodation cavity 10a along a direction parallel to the diagonal of the first accommodation cavity 10a, thereby optimizing the component layout in the first accommodation cavity 10a and being beneficial to better realizing heat exchange.

[0044] In some embodiments, the heat exchanger 20 can include a plurality of heat exchange tubes 21 and end plates 22; in some embodiments, there can be two end plates 22, and the two end plates 22 are spaced apart, and the heat exchange tubes 21 can pass through the two end plates 22.

[0045] As Figure 5 shown, in some embodiments, the end plate 22 can include an end plate body 221 and an extension portion 222. There can be two end plate bodies 221, and the end plate bodies 221 can be generally rectangular. Through holes 2211 are provided on the end plate bodies 221, and the through holes 2211 can be used for the heat exchange tubes 21 to pass through. There can be two extension portions 222, and the two extension portions 222 are disposed on two opposite sides of the end plate body 221 and extend in a direction away from the other end plate 22, and are respectively bent with the end plate body 2211. The two extension portions 222 can be oppositely arranged. One of the extension portions 222 protrudes from the end plate body 2211 along the length direction of the end plate body 2211, and a first through hole 2221 is provided thereon. The first through hole 2221 can be used for the installation of a connection component (not shown). The angle formed by the extension portion 222 and the fixed plate 15 forms the first set angle, and the angle of the first set angle can be greater than zero degrees and less than or equal to ninety degrees. The extension portion 222 is parallel to the first support portion 31.

[0046] In some embodiments, there may be two support and fixation structures 30, and the two support and fixation structures 30 are connected to two ends of the heat exchanger 20. Specifically, the two support and fixation structures 30 may be arranged at intervals along the length direction of the fixing plate 15, and each support and fixation structure 30 may be connected to an end plate 22 of the heat exchanger 20. In some other embodiments, there may also be one support and fixation structure 30.

[0047] As Figure 3 and Figure 6 shown, in some embodiments, the support and fixation structure 30 is generally in a "V" shape and is connected to the side of the fixing plate 15 close to the lower housing (the first side plate 11).

Its installation is simple, the installation efficiency is high, and the material cost can be greatly reduced, ensuring the installation stability. Specifically, the angle of the second set angle may be greater than zero degree and less than or equal to 90 degrees, and it may be equal to the angle of the first set angle. One end of the second support portion 32 extends toward the end plate 22 and forms a third set angle with the first support portion 31, and the angle of the third set angle is greater than zero degree and less than or equal to 90 degrees. The other end of the second support portion 32 may be fixed to the fixing plate 15. In some embodiments, when the fixing plate 15 is a middle partition plate, one ends of the first support portion 31 and the second support portion 32 are both connected and fixed to the side of the middle partition plate facing the first accommodation cavity 10a.

When the heat exchanger 20 is assembled, the first through hole 2221 communicates with the second through hole 311. The connection assembly (not shown) can be a first screwing assembly, which can include a first screw and a nut. The first screw can pass through the first through hole 2221 and the second through hole 311, and the nut can be screwed with the first screw, thereby connecting the heat exchanger 20 to the first support portion 31. In some other embodiments, the nut can be omitted. The second through hole 311 can be a threaded hole, and the first screw can be fixed to the second through hole 311 by screwing.

[0049] In some embodiments, a first fixing portion 33 connected to each other is provided at one end of the first support portion 31 facing the fixing plate 15.

[0050] In this embodiment, a second fixing portion 34 is provided at one end of the second supporting portion 32 facing the fixing plate 15. The second fixing portion 34 can be bent in a direction away from the first supporting portion 31, and an elastic buffer fold can also be formed between the second fixing portion 34 and the second supporting portion 32 to improve the stability of the connection between the second fixing portion 34 and the fixing plate 15. The second fixing portion 34 can be connected to one side of the middle partition plate facing the first accommodating cavity 10a. A fourth through hole 341 is provided on the second fixing portion 34, and a second screw hole (not shown) is provided on the fixing plate 15.
