[0038] Specifically, the sliding mechanism 31 can enable the plate heat exchanger to move longitudinally on the second horizontal frame 3, improve the flexibility of installation, reduce the friction between the plate heat exchanger and the second horizontal frame 3, thereby protecting the shell of the plate heat exchanger and avoiding wear and tear. At the same time, when the plate heat exchanger needs to be repaired or replaced, the plate heat exchanger can be moved to a suitable position for maintenance or replacement only by the sliding mechanism 31, which can save time and effort and reduce maintenance costs.

In addition, the design of the clamping sub-mechanism 314 enables the sliding mechanism 31 to firmly clamp the plate heat exchanger, preventing it from falling off during movement.

[0041] It should be noted that, in order to further improve the stability of the plate heat exchanger during movement of the sliding mechanism 31, one sliding mechanism 31 is arranged on each side of the shell 1; the two sliding mechanisms 31 are arranged symmetrically left and right.

[0042] In an optional embodiment, the clamping sub-mechanism 314 includes a first clamping part 3141, a second clamping part 3142, and a clamping body 3143.

The height of the outer edge part of the rotating wheel 322 is higher than the height of the edge of the sliding chute 321, and the rotating wheel 322 can rotate along the axis.

[0046] Specifically, since the height of the outer edge part of the rotating wheel 322 is higher than the height of the edge of the sliding chute 321, when the plate heat exchanger is installed on the second mounting part 52, the rotatability of the rotating wheel 322 can be used to adjust and position the plate heat exchanger through slight rotating action. This design not only makes the installation of the plate heat exchanger more convenient, but also can reduce the wear of the plate heat exchanger during installation.

[0047] It needs to be explained that more than one rotating wheel 322 is arranged in the chute 321, and two chutes 321 are arranged in the embodiment of the utility model, and the two chutes 321 are arranged in parallel on the two sides of the shell 1, and one rotating wheel 322 is arranged in the chute 321.

[0051] Specifically, L1>L2, that is, the closer the flow guide groove 23 is to the drain groove 21, the greater the depth of the flow guide groove 23. The gradually changing depth of the flow guide groove 23 can more effectively guide the flow of moisture, leaked refrigerant or other liquid impurities to the drain groove 21, and the drain groove 21 also adopts a gradually changing depth design, and this design of the flow guide groove 23 and the drain groove 21 can help reduce the residence time of moisture, leaked refrigerant or other liquid impurities, achieve rapid drainage, and ensure normal operation of the equipment.
