The assembly mode of the drying tank body 300 and the seat body 210 is simple, and positioning is achieved through the joint and the corresponding channel insertion, so that the assembly efficiency is high.
[0052] Optionally, the inlet joint 310 and the outlet joint 320 are both sealing joints. The inlet joint 310 and the outlet joint 320 can be made of rubber material, or the outer sides of the two are provided with rubber sealing rings, so that the inlet joint 310 and the outlet joint 320 form sealing joints. After the inlet joint 310 and the outlet joint 320 are inserted into the corresponding channels on the seat body 210, the sealing performance is good, and the refrigerant leakage is not easy to occur, so that the operation is safe and reliable.
[0053] It should be noted that the bracket 400 fixed on the bottom plate 170 can be an arc-shaped pressing strip. The arc-shaped pressing strip can be four, one end of the four arc-shaped pressing strips is fixed on the corresponding connecting lug 190 through a bolt, and the four arc-shaped pressing strips cooperate to improve the firmness of the combination of the drying tank and the bottom plate 170. It should be understood that, Figure 3 Only the structure of one arc-shaped pressing strip is shown for example.
[0054] In addition, the top plate and the bottom plate 170 of the heat exchanger body 100 can be hollow plates, which are light in weight.
[0055] In addition, in other embodiments, only one partition plate can be arranged inside the heat exchanger core 130, which also can achieve the effect of changing the direction of the flow channel.
[0056] The heat exchanger provided in the embodiment is connected with the drying tank body 300 through the connecting seat 200. When the model of the drying tank body 300 or the heat exchanger body 100 is adjusted, only the structure of the connecting seat 200 needs to be adjusted, and the structure of the heat exchanger body 100 does not need to be adjusted, so that the processing and manufacturing difficulty is simplified, and the processing and manufacturing cost is reduced.
