Multiple sets of agitating fan blades 27 are fixedly connected to the outside of the fan blade shaft 6. By driving the agitating motor 5 to rotate the fan blade shaft 6 and the agitating fan blades 27, the water temperature in the cold water tank 2 can be made more uniform, resulting in better cooling. A compressor 7 is fixedly connected to the inside of the main housing 1. A condenser pipe 8 is fixedly connected to the outlet of the compressor 7. A high-pressure controller 9 and an exhaust overheat protection device 10 are installed on the outer side of the condenser pipe 8 near the compressor 7. A dryer filter 11 and an expansion valve 12 are installed on the outer side of the other end of the condenser pipe 8. The other end of the tube 8 is fixedly connected to the inlet of the evaporator fins 13, and the outlet of the evaporator fins 13 is fixedly connected to the conduit 14. An antifreeze protector 15 and a temperature sensor 16 are installed on the outside of the conduit 14. The main housing 1 has an opening at the top. A thermally conductive silicone pad 17 is fixedly connected to the inside of the main housing 1, with the top of the thermally conductive silicone pad 17 in close contact with the bottom of the cold water tank 2. Four sets of air intake fans 18 are fixedly connected to the inside of the main housing 1. A dust filter 28 is fixedly connected to the outside of the main housing 1 near the air intake fans 18. The side of the main housing 1 near the dust filter 28 has an opening. The top of the main housing 1 is fixedly connected to... The main housing 1 is connected to a drive motor 19. Two sets of horizontal slide grooves 20 are provided on the inner side of the main housing 1. A long threaded rod 21 is rotatably connected to the inner side of the horizontal slide groove 20 near the drive motor 19. A guide rod 22 is fixedly connected to the inner side of the horizontal slide groove 20 away from the drive motor 19. A movable crossbar 23 is provided between the two sets of horizontal slide grooves 20. A cleaning brush 24 is fixedly connected to the side of the movable crossbar 23. A threaded hole 25 is provided above the long threaded rod 21 near the movable crossbar 23, and a guide through hole 26 is provided above the guide rod 22 near the movable crossbar 23, which is also provided below it.

[0023] The working principle of this utility model is as follows: In the initial state, an appropriate amount of water has been injected into the cold water tank 2, the water inlet 3 is sealed by the sealing plug, the manual valve on the water outlet pipe 4 is adjusted to open or close as needed, the stirring motor 5 is not started, the stirring fan blade 27 is stationary, the compressor 7, the air intake fan 18 and the drive motor 19 are all in standby mode, the cleaning brush 24 is in the initial position, and is fixed by the relative position of the moving crossbar 23 with the long threaded rod 21 and the guide rod 22;

[0024] When the chiller unit is needed, the compressor 7 starts, drawing in low-temperature, low-pressure refrigerant gas. After compression, it becomes high-temperature, high-pressure gas, which is discharged through the condenser tube 8. The high-temperature, high-pressure gas flows in the condenser tube 8 and is monitored and protected by the high-pressure controller 9 and the exhaust overheat protection device 10 to ensure safe and stable operation. The gas is cooled in the condenser tube 8 and condenses into a room-temperature, high-pressure liquid. Then, it passes through the dryer filter 11 to remove impurities and moisture, and then passes through the expansion valve 12 to reduce pressure, becoming low-temperature, low-pressure wet vapor. The low-temperature, low-pressure wet vapor enters the evaporator fins 13, absorbs heat from the water in the chilled water tank 2, causing the water temperature to drop, and at the same time, it evaporates into gas, completing the refrigeration process. The evaporated refrigerant gas returns to the compressor 7 through the conduit 14 to continue the next refrigeration cycle.

[0025] During the cooling process, the stirring motor 5 starts, driving the fan blade shaft 6 and the stirring fan blade 27 to rotate, stirring the water in the cold water tank 2, making the water temperature more uniform and improving the cooling effect;

[0026] After absorbing heat, the temperature of the evaporator fins 13 rises. Through the opening design above the main shell 1 and the forced convection of the air intake fan 18, the heat is dissipated into the air, realizing heat recovery and heat dissipation.

[0027] The dust filter 28 prevents dust and other impurities from entering the main housing 1 and affecting the normal operation of the equipment. When it is necessary to clean the evaporator fins 13, the drive motor 19 starts and drives the long threaded rod 21 to rotate. The moving crossbar 23 moves along the horizontal plate slide groove 20 through the threaded hole 25 and the threaded engagement of the long threaded rod 21, and the sliding engagement of the guide through hole 26 and the guide rod 22. The cleaning brush 24 moves accordingly to wipe the evaporator fins 13 or other parts that need to be cleaned, thereby realizing the automatic cleaning function.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
