DETAILED DESCRIPTION

[0020] The following is combined with Figures 1 to 4 The utility model is described in detail.

[0021] The utility model discloses a cooling tower with hydraulic balance capability, comprising a cooling device 1, wherein the cooling device 1 is provided with a box body 11, a water sprinkling filler 12 is provided inside the box body 11, a top cover 2 is provided on the top, a water inlet pipe 3 is provided between the top cover 2 and the box body 11, hot water enters the cooling device 1 through the water inlet pipe 3, the water inlet pipe 3 is provided outside the box body 11 with a first flow controller 31, the first flow controller 31 can detect and control the water flow of the water inlet pipe 3, the water inlet pipe 3 is provided inside the box body 11 with a plurality of nozzles 32, the hot water in the water inlet pipe 3 is sprinkled on the water sprinkling filler 12 through the nozzles 32 to form a water film, thereby cooling the water temperature, an air inlet 13 is provided in the middle of the box body 11, and cold air further cools the water film of the water sprinkling filler 12 through the air inlet 13, thereby improving the cooling rate. The bottom of the box body 11 is provided with a water tank 14, and also includes a main water tank 4 and a reserve water tank 5. The main water tank 4 is provided with a first connecting pipe 41 intercommunication with the water tank 14, a second connecting pipe 42 intercommunication with the reserve water tank 5, and a water outlet pipe 43. The two ends of the second connecting pipe 42 extend to the inner bottom of the main water tank 4 and the reserve water tank 5 respectively. The water outlet pipe 43 is provided with a second flow controller 44. The main water tank 4 is provided with a water level sensor 45, and the reserve water tank 5 is provided with an air compressor 51 for transporting the water in the reserve water tank 5 to the main water tank 4. The water of the water-spraying filler 12 flows to the water tank 14 after cooling, then enters the main water tank 4 through the first connecting pipe 41, and then is transported to the air-conditioning unit through the water outlet pipe 43 for use, and finally returns to the cooling device 1 through the water outlet pipe 43 for recycling. The first flow controller 31 and the second flow controller 44 respectively detect the water flow of the water inlet pipe 3 and the water outlet pipe 43, so that the cooling system of the air-conditioning unit is hydraulically balanced. When the water level sensor 45 senses that the water in the main water tank 4 has dropped to a certain level, the air compressor 51 starts, causing the reserve water tank 5 to replenish cooling water to the main water tank 4, so as to replenish the water evaporated during the cooling process of the cooling device 1, and stably maintain the hydraulic balance. The air compressor 51 will automatically stop after starting for a period of time, and the water capacity in the reserve water tank 5 can be determined by the number of times the air compressor 51 is started, so that workers can replenish cooling water in time.

[0022] The top of the main water tank 4 is provided with an air outlet 46, which can be opened and closed by electric control. In the scheme of the utility model, the main water tank 4 is in a semi-sealed state under normal conditions, and air and cooling water can only enter the main water tank 4 from the first connecting pipe 41 through the water tank 14. When the air compressor 51 is started, the air outlet 46 will be opened, and cooling water will enter the main water tank 4 from the reserve water tank 5, and the air in the main water tank 4 will be squeezed out from the air outlet 46. After the air compressor 51 stops, the air outlet 46 is synchronously closed to prevent debris from entering the main water tank 4.

[0023] Similarly, a choke valve a411 is provided on the first connecting pipe 41, and a choke valve b421 is provided on the second connecting pipe 42. The choke valve a411 and the choke valve b421 are opened and closed by electric control. Under normal circumstances, the choke valve b421 is in an open state to prevent the cooling water in the main water tank 4 from flowing back to the backup water tank 5. After the air compressor 51 is started, the choke valve b421 is closed, the second connecting pipe 42 is opened, and the choke valve a411 is opened synchronously to close the first connecting pipe 41 to prevent the air from flowing back from the main water tank 4 to the water tank 14 and affecting the cooling device 1. After the air compressor 51 stops, the choke valve a411 is closed synchronously to open the first connecting pipe 41, and the choke valve b421 is opened to close the second connecting pipe 42. The water tank 14 has a certain volume. After the choke valve is activated, the water in the water tank 14 cannot enter the main water tank 4. The water flowing down from the water sprinkling filler 12 can accumulate in the water tank 14 until the choke valve is closed. The water in the water tank 14 can enter the main water tank 4. The water replenishment structure of the main water tank 4 is stable and will not affect the cooling device 1.

[0024] The cooling device 1 is provided with a pressure gauge 33, which passes through the box 11 and is connected to the water inlet pipe 3. In this solution, the nozzle 32 can be opened and closed by electric control, and the hot water can be sprayed out by the nozzle 32 in atomization, so that the hot water is sprayed evenly on the water filling material 12. When the water pressure in the water inlet pipe 3 is lower than a certain value, the hot water is difficult to be atomized, and the pressure gauge 33 will control the nozzle 32 to be gradually closed until the water pressure in the water inlet pipe 3 reaches the expected value, and then control the nozzle 32 to be gradually opened, and finally the purpose of coordinating the water pressure in the water inlet pipe 3 is achieved, so that the hot water can be stably atomized and sprayed on the water filling material 12.

[0025] The top cover 2 is provided with a steam outlet 21. When the cooling device 1 cools the hot water, high-temperature water vapor can be discharged through the steam outlet 21, wherein the steam outlet 21 is a single-leaf hyperboloid structure, which can condense and collect part of the water vapor during the evaporation of the water vapor, thereby reducing the loss rate of the hot water during the cooling process.

[0026] An exhaust fan 22 is disposed in the steam outlet 21. The exhaust fan 22 can further assist in exhausting high-temperature water vapor to prevent the high-temperature water vapor from remaining for too long and affecting the cooling efficiency of the water-spraying filler 12.

[0027] The top of the water tank 5 is provided with an openable sealing cover 52. After the air compressor 51 is started a certain number of times, the staff can open the sealing cover 52 to manually replenish the water tank 5 with cooling water.

[0028] A support frame 15 is provided at the bottom of the cooling device 1. The height of the support frame 15 is similar to that of the main water tank 4. The support frame 15 is installed near the main water tank 4. The horizontal position of the water tank 14 is higher than the top of the main water tank 4. The water in the water tank 14 can flow into the main water tank 4 by gravity without the need for an additional water pump.

[0029] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
