And the two modules are independently installed, so that not only can new repair users be met, but also old replacement users can be met.

The refrigeration assembly includes a second housing 21, a compressor 22, an evaporator 23, a condenser 24, and a cooling fan 25, wherein the second housing 21 is disposed above the first housing 11, wherein the compressor 22, the evaporator 23, the condenser 24, and the cooling fan 25 may be disposed within the second housing 21, and a path for a refrigerant is formed between the compressor 22, the evaporator 23, and the condenser 24.

Optionally, the heat-conducting plate 2411 is a metal plate, such as preferably an aluminum plate, and the two aluminum plates are hot rolled, pressed, and inflated to form the first cooling medium channel 242 described above, and then rolled into a desired shape. The bearing pressure of the refrigerant in the first refrigerant channel 242 after hot rolling reaches 2.3MPa, and the refrigerant is in zero-clearance contact with the heat conducting material, so that the heat exchange efficiency is extremely high, and the surface temperature of the condenser in the natural environment is not higher than 50 ℃.

The inner heat radiation surface radiates heat by the oil smoke passing through the smoke exhaust passage 2412, and the outer heat radiation surface contacts room temperature air entering the second housing 21 from the kitchen indoor environment when in operation, thereby achieving a certain degree of heat radiation.

In order to further improve the heat exchange efficiency, the condenser 24 further includes a second main body 243 and a second refrigerant channel 244, which are identical in structure and molding manner to the first main body 241 and the first refrigerant channel 242, except that the pipe diameter of the second main body 243 is smaller than that of the first main body 241, and the second main body 243 is arranged in a space surrounded by the first main body 241 at intervals.

The support blocks 246 may have at least two, and are uniformly arranged along the circumferential direction of the first body 241 (the second body 243), preferably radially distributed. In addition, the heat conductive sheet 247 may be disposed in the second body 243, and the heat conductive sheet 247 may be disposed in at least two of the heat conductive sheets 247, and the heat conductive sheets 247 may extend from the pipe wall of the second body 243 to the middle (the middle of the space surrounded by the second body 243 is not strictly required to extend to the center) and be radially distributed. The heat released from the second body 243 can thus be dissipated more rapidly by the heat-conducting fins 247 radially inward with a large central wind velocity.

In the above embodiment, the first body 241 and the second body 243 have the same shape, and the first refrigerant passage 242 and the second refrigerant passage 244 have the same shape. Alternatively, the shape of the first body 241 and the second body 243 may also be different, such as may be cylindrical and/or spiral; the first refrigerant channel 242 and the second refrigerant channel 244 may also have different shapes, such as spiral and/or parallel flow back, as shown in fig. 8-11, and the first refrigerant channel 242 and the second refrigerant channel 244 are parallel flow back and are each in a divided-and-multiple structure (the inlet and the outlet are shared, and a plurality of sub-channels are therebetween).

In the process of manufacturing, referring to fig. 8, a raw aluminum plate is first hot rolled and inflated into two original plates, namely a small plate corresponding to the second main body 243 and a large plate corresponding to the first main body 241, and the first refrigerant channel 242 and the second refrigerant channel 244 are connected by a flexible pipe 245.
