The tube sheet has a width in the front and rear directions. The tube sheet passes through the inner side of the two tube sheets. One or more defrosting heating tubes corresponding to the tube sheet also pass through the inner side of the two tube sheets. An expansion valve, a solenoid valve, and a check valve are installed on the outer side of the front tube sheet and placed in the front cavity. A defrosting over-temperature sensor corresponding to the tube sheet is installed on the front side of the rear tube sheet and placed in the rear cavity.

[0009] The liquid inlet valve and return gas valve of this utility model are integrated into the inner plate, forming a modular assembly directly fixed to the shell. The top plate, outer plate, inner plate, bottom plate, front plate, and rear plate are directly wrapped around the two side tube plates of the evaporator, simplifying the overall space while ensuring structural connection strength. In use, the liquid inlet valve is directly connected to the solenoid valve, the other side of which is connected to the expansion valve, and the other side of the expansion valve is connected to the evaporator. Refrigerant is sent into the evaporator, where it is cooled by airflow from the outer plate fan. The refrigerant undergoes forced heat exchange with the air in the tube side, absorbing heat and becoming a low-pressure gas. It then flows through the check valve, which is connected to the return gas valve, and finally re-enters the compressor for compression and circulation. The base plate of the air cooler also features a water collection tray with a drain connector, and hangers are installed on the upper part of the inner and outer plates. Various valves are installed in the front cavity of the front plate and the front side tube plate, making full use of the installation space. Maintenance can be performed by removing the front plate. This design features a compact structure, reduced space occupation, lower manufacturing and installation costs, convenient overall equipment installation, and reduced safety hazards.
