Based on the implementation cases in the present utility model, all other implementation cases obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present utility model.

[0017] A circulating water cooling integrated device comprises a circulating water tank 1, a circulating water supply pump 2, a water level sensor 5, a temperature sensor 6, an integrated box body 7 and a control box 9. The circulating water tank 1, the circulating water supply pump 2 and the control box 9 are arranged inside the integrated box body 7. The water inlet pipe of the circulating water supply pump 2 is connected to the circulating water tank 1, the water outlet pipe of the circulating water supply pump 2 is connected to the water inlet pipe of the cooling water user 3, the water outlet pipe of the cooling water user 3 is connected to the water inlet of the heat exchange equipment 4, and the water outlet of the heat exchange equipment 4 is connected to the circulating water tank 1; the water level sensor 5 and the temperature sensor 6 are both installed in the circulating water tank 1, and the signal output ends of the water level sensor 5 and the temperature sensor 6 are both connected to the signal input end of the control box 9, and the signal output end of the control box 9 is connected to the circulating water supply pump 2 and the water replenishment electric valve 8.

[0018] A check valve 15 is provided on the water outlet pipe of the circulating water supply pump 2 .

[0019] The water inlet pipe of the circulating water supply pump 2 is provided with a water pump inlet valve 17 , and the water outlet pipe is provided with a water pump outlet manual valve 13 and a water pump outlet electric valve 14 .

[0020] The integrated box 7 is installed on the upper part of the ground, and an equipment foundation 11 is provided at the lower part thereof.

[0021] The circulating water supply pump 2 is an electric centrifugal pump.

[0022] The material of the integrated box 7 is carbon steel or glass fiber reinforced plastic.

[0023] The circulating water supply pump 2 and the control box 9 are installed on the same side of the integrated box body 7.

[0024] The integrated box body 7 is provided with an inspection door 10 on the side where the circulating water supply pump 2 and the control box 9 are installed.

[0025] The system further comprises a flow meter 12 , which is arranged between the circulating water supply pump 2 and the cooling water user 3 .

[0026] In actual use, the circulating water tank 1, circulating water supply pump 2, water level sensor 5, temperature sensor 6, control box 9, flow meter 12, water pump outlet manual valve 13, water pump outlet electric valve 14, check valve 15, pressure sensor 16, and water pump inlet valve 17 are all mounted above ground for easy inspection and maintenance. These components are all housed within an integrated housing 7, extending the service life of each component. The integrated housing 7 is located near the cooling water user 3. The water level controls the start and stop of the circulating water supply pump 2, thereby preventing equipment damage caused by untimely cooling water supply. The exterior of the integrated housing 7 can be displayed with promotional slogans, images, etc., creating an aesthetically pleasing appearance. The circulating water supply pump 2 utilizes an electric centrifugal pump, and the integrated housing 7 can be constructed of carbon steel or fiberglass reinforced plastic. The inlet and outlet pipes of the circulating water supply pump 2 are both equipped with valves for use in emergency troubleshooting.

[0027] The circulating water supply pump 2 draws water from the circulating water tank 1 and pressurizes it to supply it to the cooling water user 3. After being used by the cooling water user 3, the high-temperature water enters the heat exchanger 4 due to the residual pressure and is cooled. The cooled water then enters the circulating water tank 1 and is then pressurized by the circulating water supply pump 2 and supplied to the cooling water user 3 for recycling. A water level sensor 5 is used to detect the water level in the circulating water tank 1. The water level sensor 5 can send two signals to the control box 9: a high water level alarm signal and a low water level alarm signal. When the control box 9 receives the high water level alarm signal, it closes the water supply electric valve 8 to prevent overflow and drainage of the circulating water tank 1. When the control box 9 receives the low water level alarm signal, it opens the water supply electric valve 8 to prevent the circulating water tank 1 from lowering its water level, which could cause the circulating water supply pump 2 to have difficulty absorbing water and thus damage the equipment. The temperature sensor 6 can send a high temperature alarm signal to the control box 9. When the control box 9 receives the high temperature alarm signal, it opens the water supply electric valve 8 to replenish low-temperature water to lower the water temperature in the circulating water tank 1 and meet the cooling water temperature requirements of the cooling water user 3.

[0028] The control box 9 is a local control box that receives high and low water level signals from the circulating water tank 1, detected by the water level sensor 5. When the control box 9 receives a high water level alarm signal, it closes the water supply valve 8 to prevent overflow from the circulating water tank 1. When the control box 9 receives a low water level alarm signal, it opens the water supply valve 8 to prevent the circulating water supply pump 2 from losing water due to a low water level in the circulating water tank 1, which could cause damage. The control box 9 also receives high temperature alarm signals from the temperature sensor 6. When this signal is received, the control box 9 opens the water supply valve 8 to replenish low-temperature water to lower the water temperature in the circulating water tank 1 and meet the cooling water temperature requirements of the cooling water user 3. The control box 9 has a remote communication interface and is manufactured by Shanghai Dongfang Pump Industry (Group) Co., Ltd., using the DFK series model.

[0029] The utility model can be promoted and used in the industry, and has significant environmental and economic benefits.
