The condensing fan 26 is mounted on the condenser 22, and an axis of the condensing fan 26 is aligned with a normal direction of a windward side of the condenser 22.
A first end of the tee joint 28 is connected with an evaporation outlet pipe section 25a of the evaporator 25, a second end of the tee joint 28 is connected with the air suction port 21a, and a third end of the tee joint 28 is connected with one end of the filling bolt 27. The other end of the filling plug 27 is normally closed, and the refrigerant can be supplemented to the refrigeration system through the other end of the filling plug 27.
As shown in fig. 7, the housing assembly 3 is composed of a cylinder 30 and a flange 31, wherein a plurality of air inlet holes 30a and a plurality of air outlet holes 30b are formed in the side surface of the cylinder 30, and a plurality of mounting holes 31a are formed in the flange 31.

The liquid cooling device 100 is powered by the power supply terminal on the upper cover assembly 2, and then the switch 12 on the upper cover assembly 2 is pressed to start the operation of the liquid cooling device 100. At this time, a refrigeration effect is generated inside the evaporator 25, so that the evaporator 25 absorbs heat from the liquid in the container 200, thereby cooling the liquid in the container 200 and achieving the purpose of cooling the liquid. The specific working process is as follows: when the switch 12 is pressed, the controller 11 controls the micro refrigerant compressor 21 and the condensing fan 26 to be operated, respectively. When the micro refrigeration compressor 21 is operated, refrigerant gas introduced into the compressor through the suction port 21a is compressed into high-temperature and high-pressure gas, discharged from the discharge port 21b, and introduced into the condenser 22 through the condensation inlet 22 a. In the condenser 22, the refrigerant gas of high temperature and high pressure releases heat to the air flow forced to flow by the condensing fan 26, and the refrigerant is condensed and turns into liquid of high temperature and high pressure. The high-temperature and high-pressure refrigerant liquid flows out of the condenser 22 through the condensation outlet 22b and then enters the dry filter 23 through the dry filter inlet 23 a. In the dry filter 23, the refrigerant is dried, filtered to remove moisture and impurities possibly contained therein, and then flows out of the dry filter outlet 23b into the throttling element 24. The liquid refrigerant passes through the throttling element 24 and the pressure is reduced, and a portion of the refrigerant flashes out into a low pressure gas-liquid mixture. The low pressure refrigerant gas-liquid mixture passes through the base pan 20 and enters the evaporator 25 through the evaporator inlet tube 25a, where the low pressure refrigerant mixture is continuously evaporated to absorb the heat of the liquid in the container 200, thereby lowering the temperature of the liquid in the container 200 and achieving a cooling effect. The refrigerant absorbing the heat of the liquid is totally evaporated and becomes a completely gaseous refrigerant. The gaseous refrigerant is again sucked into the micro refrigerant compressor 21 through the suction port 21a, compressed again, and circulated.
In fig. 8, the shelf 300 may be a lid carried by the container 200 itself, but has a hole in the middle through which the evaporator 25 passes. Or more simply, the shelf 300 may be replaced with a grid or any form of support.

However, the present invention is not limited to the specific shape of the chassis, the cylinder and the lid, and the cross-sectional shape of the chassis, the cylinder and the lid may be rectangular, regular polygonal or any other shape.
The length of the evaporation inlet pipe section 25a and the evaporation outlet pipe section 25b of the evaporator 25 can be any length, therefore, the device can be applied to the container 200 with any depth.
In particular, the evaporation inlet pipe section 25a and the evaporation outlet pipe section 25b may be flexible pipes, i.e. the evaporator 25 may be inclined at the lower part of the refrigerator assembly 2, which makes it possible to dispense with the evaporator 25 directly below the chassis 20, thus providing more convenience in use and more applicable scenarios.
