[0014] The working process of the utility model is:
[0015] The recovery pipeline 2 transports the cooled water of the equipment to the water collecting tank 1. The temperature sensor 6 in the water collecting tank 1 detects the water temperature inside the water collecting tank 1. When the water temperature reaches the set value, the PLC controller 5 processes the data collected by the temperature sensor 6 in real time. The PLC controller 5 outputs an execution signal, and the solenoid valve 14 and the cooling fan 9 are energized. The solenoid valve 14 opens and the cooling fan 9 starts. The water in the water collecting tank 1 is transported to the cooling mechanism 3, and the cold air enters the shell 7 through the pipeline. The cold air is distributed to the cooling coil group 8. Through heat conduction, the surface of the cooling coil group 8 exchanges heat with the cold air. Since the temperature of the air is lower than the temperature of the water in the cooling coil group 8, the heat of the water is transferred to the air in the shell 7 through the cooling coil group 8. The air outlet 10 forms a convection port, and the heat flow in the shell 7 flows out from the air outlet 10 to reduce the temperature of the water; the cooled water The water flows out from the outlet of the cooling coil group 8 and enters the water storage tank 4 through the water inlet pipe 11; the water in the water storage tank 4 rises from the bottom to the top, and the filter plate 13 realizes the filtering effect. The radar level gauge 15 monitors the water level in the water storage tank 4. When the water level reaches the upper limit setting value, the PLC controller 5 outputs a line signal, the solenoid valve 14 and the cooling fan 9 are powered off and closed, and the booster pump 16 is powered on and started to transport the water in the water storage tank 4 to the cooling water supply pipeline for use by the equipment that needs to be cooled. When the radar level gauge 15 monitors the water level in the water storage tank 4 and the water level reaches the lower limit setting value, the booster pump 16 is powered off and closed; the solenoid valve 14 and the cooling fan 9 are powered on, the solenoid valve 14 is opened, and the cooling fan 9 is started to continue to transport the water in the water collection tank 1 to the cooling coil group 8 for cooling. The steps are the same as above; the utility model realizes the function of cooling and lowering the temperature of the equipment, thereby achieving the purpose of energy saving and consumption reduction;
