[0002] The evaporator is a very important component among the four major refrigeration components. The low-temperature condensed "liquid" passes through the evaporator and exchanges heat with the outside air, "gasifying" and absorbing heat to achieve the refrigeration effect. The evaporator mainly consists of a heating chamber and an evaporation chamber. The heating chamber provides the heat required for the liquid to evaporate, promoting the liquid to boil and vaporize, and the evaporation chamber completely separates the gas-liquid two phases.

[0003] In order to ensure the stable installation of the evaporator, the bases of most evaporators are fixedly installed in the use area. During maintenance, disassembly is required. The relatively heavy base occupies a large space, and the support structure has poor adjustability, making it inconvenient to quickly remove the evaporator, which is time-consuming and laborious.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] In the first embodiment of the present utility model, as shown in Figure 1 and Figure 2 shown, an evaporation tube installed on a base 2 is provided inside an evaporator housing 1. The evaporation tube is a relatively mature existing technology, and its specific structure will not be elaborated here. A height adjustment mechanism 3 is provided on the side of the evaporator housing 1. The height adjustment mechanism 3 includes a vertically arranged adjustment frame 31. An adjustment plate 32 is slidably connected inside the adjustment frame 31. The front surface of the adjustment plate 32 is fixedly connected to the base 2 through a connecting plate 24. A fixing plate 21 extends upward on the side of the base 2 away from the height adjustment mechanism 3. A positioning mechanism 4 is provided on the side of the adjustment frame 31. Through the cooperation among the adjustment frame, the adjustment plate, and the base, when it is necessary to adjust the height of the evaporator, the operator can pull the pull ring with one hand to separate the top column from the adjustment plate, and hold the handle tightly with the other hand to apply an upward force. After moving to a suitable position, release the pull ring, and the top column is embedded in the positioning groove again to clamp the adjustment plate, enabling the installation of the evaporator at different heights and facilitating disassembly during the maintenance process.

[0021] Heat dissipation ribs 11 are cross-connected on the surface of the evaporator housing 1, increasing the heat dissipation area, enabling the heat generated by the evaporation tube to be dissipated as soon as possible, thereby reducing the generation of condensed water.

[0022] A handle 33 is fixed to the top of the adjustment plate 32, providing a force application point for the operator to lift the adjustment plate 32 to adjust the height of the evaporator.

[0023] A plurality of positioning grooves 321 arranged at equal intervals in the vertical direction are provided on the side of the adjustment plate 32 close to the positioning mechanism 4. During the height adjustment process, the top column in the positioning mechanism 4 is pressed by a return spring 44 and is embedded and clamped in the positioning grooves 321. The top column 42 is embedded in the limiting groove 321 on the corresponding side of the adjustment plate 32. The fixation of the adjustment plate 32 is achieved through the frictional force between the top column 42 and the adjustment plate 32 and the acting force between the top column 42 and the end face of the positioning groove 321. At the same time, the plurality of equally spaced positioning grooves 321 can facilitate the operator to quickly confirm the lifting height. Specifically, the height can be roughly estimated by the number and position of the positioning grooves 321 exposed above the adjustment plate 32.

[0024] First connection holes 22 are provided on the surface of the base 2 and are fixedly connected to the evaporator housing 1 through bolts. Second connection holes 23 are provided on the fixing plate 21 of the base 2 and are fixedly connected to the vehicle body through bolts, ensuring the connection strength among the evaporator housing, the base, and the vehicle body.

[0025] As shown in Figure 2 and Figure 3As shown in the figure, the positioning mechanism 4 includes a positioning plate 41 fixed to the side surface of the adjustment frame 31. A top column 42 passing through the positioning plate 41 and the adjustment frame 31 is provided in the middle of the positioning plate 41. A pull ring 43 is provided at one end of the top column 42 away from the adjustment frame 31. A return spring 44 is installed between the pull ring 43 and the positioning plate 41. The staff can pull the pull ring 43 with one hand to separate the top column 42 from the positioning groove 321 on the adjustment plate 32, and hold the handle 33 tightly with the other hand to apply an upward force. After moving to a suitable position, release the pull ring 43, and the top column 42 is embedded in the positioning groove 321 provided at other positions again to clamp the adjustment plate, realizing the installation of the evaporator at different heights.

[0026] In the second embodiment of the present application, as Figure 4 shown, the difference from the embodiment is that a sliding groove 34 is provided on one side of the adjustment plate 32 close to the connecting plate 24. The sliding groove 34 is sleeved on the outside of the connecting plate 24. The sliding groove 34 and the top of the connecting plate 24 are provided with straight groove openings corresponding in position. A support plate 35 located below the base 2 is provided at the bottom of the sliding groove 34. Through the connection relationship between the sliding groove 34 and the connecting plate 24, the horizontal position adjustment of the evaporator can be realized, avoiding the problem that the evaporator cannot be fixed due to the change of the position during the height adjustment process.
