The first housing 11 may be a combination of one or more housings.

The oil smoke absorbing component and the refrigerating component respectively form independent modules, and the refrigerating component is carried on the oil smoke absorbing component during installation, so that the refrigerating component does not occupy the space on the left side and the right side of the first shell 11 of the oil smoke absorbing component, and the influence on the oil smoke absorbing effect of the fan frame (part of the first shell 11) for arranging the main fan 12 can be avoided. 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, and a condenser 24, wherein the compressor 22, the evaporator 23, and the condenser 24 may be disposed within the second housing 21, and a path of a refrigerant is formed between the compressor 22, the evaporator 23, and the condenser 24. The working principle of the refrigeration component is the same as that of the prior art.

The condenser 24 includes a main body 241 and a refrigerant channel 242, the main body 241 is hollow and pipe-shaped, and may be cylindrical or rectangular parallelepiped, the refrigerant channel 242 is formed inside a wall portion of the main body 241, and the refrigerant channel 242 may preferably be spirally wound. The wall portion of the main body 241 includes two heat conductive plates 2411, the refrigerant channel 242 is formed between the two heat conductive plates 2411, and the two heat conductive plates 2411 have a gap only at a position where the refrigerant channel 242 is formed, and are attached to each other at other portions (gaps existing at portions other than the refrigerant channel 242 due to a processing problem, such as bubbles, etc., should be regarded as a case without gaps). Alternatively, 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 above-described coolant passages 242 therebetween, and then rolled integrally into a desired shape. The bearing pressure of the refrigerant in the 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 conventional air conditioner is of a fin type or a winding type, which is commonly used in the prior art, and the refrigerant and the heat conducting material cannot be completely in clearance fit, so that heat transfer is not smooth, the temperature of the condenser is high, and the integral refrigeration effect of the refrigeration assembly is further affected.

That is, the space surrounded by the heat-conducting plates 2411 in the inner layer of the main body 241 is configured as a smoke exhaust channel 2412 through which the smoke exhausted by the air blower 12 passes before reaching the public flue or being exhausted into the room, and the inner side wall surface of the heat-conducting plates 2411 in the inner layer (i.e., the inner side wall surface 2413 of the main body 241) and the outer side wall surface of the heat-conducting plates 2411 in the outer layer (i.e., the outer side wall surface 2414 of the main body 241) both form heat dissipation surfaces. 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. The room temperature air constitutes a heat dissipating fluid.

The front side of the second housing 21, for example, near the top, is provided with a cool air outlet 211, an evaporator 23 may be disposed near the cool air outlet 211, and cool air heat exchanged by the evaporator 23 is blown out from the cool air outlet 211 (a separate fan may be provided to provide power) into the kitchen to provide a comfortable cooking environment temperature for the user. The other side surfaces of the second housing 21, for example, the left and right sides, are provided with air inlets 212 for supplying air (room temperature air) into the second housing 21.

To further improve the heat exchange efficiency, a hollow outer shell 243 may be provided outside the main body 241 of the condenser 24, which is adapted to the shape of the main body 241 and has a size larger than the main body 241 so as to be disposed at a distance from the outer periphery of the main body 241 to form an interlayer 244 between the outer shell 243 and the outer side wall surface 2414 of the main body 241. In this embodiment, the body 241 is longitudinally, particularly vertically, arranged, and the outer casing 243 is closed with the body 241 at the upper and lower ends of the interlayer 244, respectively.

To this end, the refrigeration assembly further comprises a water collection sump 25 provided below the evaporator 23 for receiving condensed water flowing down the evaporator 23. The refrigeration assembly further includes a water pump 261, a water inlet pipe 262, and a water outlet pipe 263, the water pump 261 being in fluid communication with the sump 25 via a conduit, the water inlet pipe 262 connecting the water pump 261 and the condenser 24, respectively, thereby fluidly connecting the water pump 261 and the interlayer 244, the water outlet pipe 263 also being connected with the condenser 24, and being in fluid communication with the interlayer 244. The position where the water inlet pipe 262 is connected with the condenser 24 is higher than the position where the water outlet pipe 263 is connected with the condenser 24, as in the present embodiment, the water inlet pipe 262 is connected at the top of the corresponding interlayer 244, and the water outlet pipe 263 is connected at the bottom of the corresponding interlayer 244.

Thereby, the condensed water flowing down from the evaporator 23 is pumped into the interlayer 244, so that the condensed water flows from top to bottom along the interlayer until being discharged from the water outlet pipe 263, thereby realizing heat dissipation to the outer side wall surface of the main body 241. The hot water discharged from the water outlet pipe 263 can be recycled, and also can be discharged to an oil cup of the fume exhaust assembly, or directly discharged, etc.

Alternatively, other cooling water sources may be used instead of the condensed water, such as a separate water storage tank, and the water discharged from the water outlet pipe 263 may flow back to the water storage tank.
