Abstract
Description
Technical Field
[0001] The utility model relates to an air-water cooling device with an automatic temperature adjustment function, belonging to the technical field of equipment control systems. Background Art
[0002] The air-water cooling system is a crucial temperature-control device in the power distribution room. Its primary function is to regulate the temperature of high-power equipment within the distribution room, keeping it within a reasonable range. Therefore, the proper operation of the air-water cooling system is directly related to the stable operation of the power distribution room's power supply equipment. The air-water cooling system primarily consists of an air-water cooling cabinet, piping, and a ventilation hood. During operation, the air-water cooling system directs hot air from the equipment through the ventilation hood into the heat exchanger within the air-water cooling cabinet. Cooling water flows through the heat exchanger, cooling the hot air. Driven by the fan, the cooled air enters the equipment, displacing the hot air, and this cycle repeats. Simultaneously, cooler cooling water enters the heat exchanger through the water inlet, exchanges heat with the circulating air, and becomes hotter cooling water, which then flows out of the heat exchanger's outlet. Equipment temperature is primarily determined by the operating load: as the load increases, the equipment temperature rises, while as the load decreases, the equipment temperature decreases. Currently, the temperature regulation function of air-water cooling systems is mainly achieved by manually adjusting the opening of the water inlet valve. Manual adjustment often has lag and uncertainty. Once the temperature rises beyond the adjustment range, the equipment temperature will rise exponentially, causing serious damage to the equipment. If the temperature is too low, condensation will form, which will also cause damage to the equipment. Damage to the equipment will affect production, resulting in a loss of economic benefits for the enterprise. Summary of the Invention

[0028] When in use, after turning on the power switch, the air-water cooling device fan starts, and the manual valves of the inlet and outlet water pipes are opened. Cooling water enters the heat exchanger through the water inlet pipe. After exchanging heat with the indoor circulating hot air, it becomes hotter cooling water and flows out of the heat exchanger outlet. The circulating hot air is replaced by a lower temperature and re-enters the room. The temperature is measured by the indoor temperature sensor. When the indoor temperature is higher than the set upper limit temperature, the electric control valve increases the opening to 100%; when the indoor temperature is lower than the set lower limit temperature, the electric control valve decreases the opening to 50%.

When regular cleaning is required after a period of use, close the water inlet valve and the water outlet valve, open the second backwash valve and the sewage valve, and the cooling water flows from the water inlet pipe through the second backwash valve into the water outlet pipe, and reversely flushes the interior of the air cooling device. The sewage is discharged through the sewage pipe.
