[0029] Combined with appendix Figures 1-7 The chiller unit with temperature control function includes a frame 12, in which a chilled water tank 11, a heat exchange box 20, an evaporator 24 and several fan units 26 are fixedly installed in sequence.

[0030] A first water pump 15 and a second water pump 16 are fixedly installed in the cold water tank 11 between the cold water tank 11 and the heat exchange tank 20. A heat exchanger 27 is fixedly installed in the heat exchange tank 20. The heat exchanger 27 is provided with an inlet and an outlet. The water is cooled by the heat exchanger 27. The inlet of the heat exchanger 27 is fixedly connected to the first pipe 14. The outlet of the heat exchanger 27 is fixedly connected to the second pipe 18. The other end of the second pipe 18 is fixedly connected to the inlet of the second water pump 16. The outlet of the second water pump 16 is fixedly connected to the third pipe 13. One end of the third pipe 13 is fixedly connected to the cold water tank 11.

[0031] The cold water tank 11 is a cold source used to supply cold water within a certain temperature range. A temperature sensor is installed in the cold water tank 11 to monitor the temperature in real time. The cold water tank 11, the No. 3 pipe 13, the No. 2 water pump 16, the heat exchanger 27 and the No. 1 pipe 14 form a water circulation structure to control the temperature of the cold water.

[0032] Both fan units 26 are fixedly connected to one side by an air inlet pipe 25, which is fixedly connected to the evaporator 24. An evaporation chamber 33 is opened inside the evaporator 24, and the evaporation chamber 33 is fixedly connected to an air outlet pipe 21. The air outlet pipe 21 is fixedly connected to the heat exchange box 20. A water box 28 is fixedly installed inside the evaporation chamber 33. A water outlet assembly is provided inside the water box 28. The water outlet assembly includes a water tank 32 opened inside the water box 28. Multiple water outlets 48 are opened at the bottom of the water tank 32. A sealing strip 49 is slidably inserted into the water outlet 48. 9. Insert the water outlet 48 to close the water outlet 48. The top of the sealing strip 49 is provided with a crossbeam 31 fixed in the water tank 32. Two guide rods 34 slide through the crossbeam 31. The guide rods 34 are fixed to the bottom sealing strip 49. Float 30 is fixed at the top of the two guide rods 34. The bottom of each water outlet 48 is provided with a water nozzle 36 fixed to the bottom of the water box 28. The water nozzle 36 has a water outlet channel 50 that communicates with the water outlet 48. The bottom opening of the water outlet channel 50 is narrowed and the opening width is close to the width of the water box 28.

[0033] The No. 1 water pump 15 is provided with a water pump port 17, which is used to connect to an external water source for water intake. The outlet of the No. 1 water pump 15 is fixedly connected to the No. 4 pipe 29, and the other end of the No. 4 pipe 29 is inserted into the water tank 32.

[0034] The float 30 has a hollow structure. After the No. 1 water pump 15 is started, water enters through the pump port 17 and is transported to the water tank 32 through the No. 4 pipe 29. The water level in the water tank 32 rises, causing the float 30 to float. The float 30 drives the sealing strip 49 to rise and detach from the outlet 48. The water in the water tank 32 will flow out from the outlet 48 and the water outlet 50. Due to the shape of the opening of the water outlet 50, the water coming out of the water outlet 50 forms a thin water curtain. The fan unit 26 takes in air and blows it into the evaporation chamber 33 through the air inlet pipe 25. The air passes through the water curtains, accelerating the evaporation of water at the water curtains and forming cold air. The cold air is blown into the heat exchange box 20 to cool the water in the heat exchanger 27. The water curtain is used to increase the contact area with the air, but it does not directly blow out a large amount of water mist. It has a good cooling effect without increasing the burden of excessive humidity in the system.

[0035] Several opposing plates 38 are fixed at the bottom of the evaporation chamber 33. A winding drum 39 is rotatably installed between the plates 38. The number of winding drums 39 is the same as the stated number. A delay layer 40 is wound on the winding drum 39. The delay layer 40 extends out of the winding drum 39. The bottom opening of the water outlet 50 is directly opposite the delay layer 40. The surface of the delay layer 40 is rough. The water curtain discharged from the water outlet 50 will flow directly down the delay layer 40. The rough surface of the delay layer 40 is used to delay the flow of the water curtain, increase the contact time between the water curtain and the air, and improve the cooling effect.

[0036] The delay layer 40 can be made of materials such as mesh, perforated cloth, or silicon carbide film, ensuring that the water curtain can be formed normally while also having a certain gripping force to prevent the generation of spilled water mist.

[0037] The delay layer 40 is connected to a pulling mechanism, which can pull the delay layer 40 out of the take-up drum 39. A rotating shaft 53 is fixed on one side of the take-up drum 39, and a torsion spring sleeve 37 is fixed on the upright plate 38. A torsion spring 54 is fixedly installed between the rotating shaft 53 and the torsion spring sleeve 37. The torsion spring 54 is used for the reset of the take-up drum 39. The pulling mechanism includes a power shaft 44 rotatably installed in the evaporation chamber 33. The power shaft 44 is fixed to the motor shaft of the motor 23. The motor 23 is fixed to the evaporation chamber 33. Outside the evaporator 24, several winding wheels 45 are fixed on the power shaft 44. A rope 35 is wound on the winding wheels 45. The other end of the rope 35 is fixed to the connecting post 46. The delay layer 40 is fixed to the connecting post 46. The rope 35 is guided by a fixed pulley seat 42. The fixed pulley seat 42 is fixedly installed inside the evaporator 33. Tracks 41 are fixed inside the vertical plate 38. Sliding blocks 47 are slidably installed in the tracks 41. The connecting post 46 is fixedly arranged between two sliding blocks 47.

[0038] A control box 51 is fixed on the frame 12. After the temperature sensor in the cold water tank 11 detects that the temperature has stabilized above the critical value, the control box 51 controls the motor 23 to start. The motor 23 drives the power shaft 44 to rotate, and the power shaft 44 drives the winding wheel 45 to rotate. The winding wheel 45 winds the rope 35, and the rope 35 pulls the connecting column 46 down. The connecting column 46 pulls more of the delay layer 40 from the winding drum 39, thereby increasing the contact area between the water curtain and the delay layer 40, allowing the water curtain to stay for a longer time, thereby further increasing the cooling effect.

[0039] It should be noted that the bottom of the evaporator 24 is fixedly connected to the wastewater pipe 22, which is used to discharge wastewater. The wastewater is pumped away by an external water pump to prevent bacterial contamination. The heat exchange box 20 has an air outlet 19 on one side for air outlet.

[0040] How to use:

[0041] The cold water tank 11 serves as a cold source, providing cold water. A temperature sensor inside the cold water tank 11 monitors the cold water temperature in real time. When the cold water temperature exceeds a set value, the control box 51 controls the No. 1 water pump 15 to start. After starting, the No. 1 water pump 15 draws water through the pump inlet 17 and transports it to the water tank 32 through the No. 4 pipe 29. The water level in the water tank 32 rises, causing the float 30 to float. The float 30 then lifts the sealing strip 49, disengaging it from the outlet 48. Water in the water tank 32 flows out from the outlet 48 and the outlet channel 50. Due to the shape of the opening of the outlet channel 50, the outlet channel... The water coming out of the 50 is in the form of a thin water curtain. The control box 51 controls the fan unit 26 to start air intake. The fan unit 26 intakes air and blows it into the evaporation chamber 33 through the air intake pipe 25. The air passes through the water curtains, accelerating the evaporation of water at the water curtains and forming cold air. The cold air blows into the heat exchange box 20 to cool the water in the heat exchanger 27. The control box 51 controls the second water pump 16 to start. The second water pump 16 draws water from the cold water tank 11 into the heat exchanger 27 through the first pipe 14 for cooling. The cooled water flows back to the cold water tank 11 through the third pipe 13 until it drops to the set temperature range.

[0042] When the cold water temperature exceeds the critical value, the control box 51 controls the motor 23 to start. The motor 23 drives the power shaft 44 to rotate, which in turn drives the take-up reel 45 to rotate. The take-up reel 45 winds the rope 35, which pulls the connecting post 46 down. The connecting post 46 pulls more of the delay layer 40 from the take-up drum 39, thereby increasing the contact area between the water curtain and the delay layer 40 until the temperature drops to the set range. Then, the motor 23 drives the power shaft 44 to rotate in the opposite direction, which in turn drives the take-up reel 45 to rotate. The take-up reel 45 releases the rope 35, the torsion spring 54 resets, and the take-up drum 39 rotates in the opposite direction to wind the delay layer 40.

[0043] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
