Control method and module of coolers of water cooling system

Abstract

The invention discloses a control method of coolers in a pure water cooling system for high-power power electronic equipment. A temperature monitoring module, a cooler state monitoring module and a cooler control module for controlling the work states of all the coolers are adopted for cooler control. The method comprises the steps that 1, the temperature of a cooling medium in the cooling system and the work states of all the coolers are monitored in real time, and the running time of each cooler is calculated; 2, the collected temperature of the cooling medium in the cooling system and the calculated running time of all the coolers are compared with corresponding set values respectively, and comparison results are obtained; 3, the coolers are controlled to be started or stopped according to the temperature comparison result or the running time comparison result of all the coolers. The stability of the cooling system is improved.

Description

technical field [0001] The invention relates to the field of control of a cooling device for high-power power electronic equipment, in particular to a control method and a control module of a water cooling system cooler. Background technique [0002] The cooling system in the operation system of high-power power electronic equipment is related to the safe operation and service life of the cooled device, and is a very necessary supporting equipment. [0003] The working condition of the cooler of the water cooling system directly affects the cooling effect, which in turn affects the safe operation and load capacity of the cooled equipment. The traditional cooler control mode controls the corresponding number of groups of coolers to start and stop according to the temperature reaching the corresponding temperature start-stop setting value. When the ambient temperature is low, the cooling effect of the cooler is stronger, the cooler quickly reduces the system temperature, and t...

AI Technical Summary

Problems solved by technology

The traditional cooler control mode controls the start and stop of the corresponding groups of coolers according to the temperature reaching the corresponding temperature start-stop fixed value. In the case of low ambient temperature, the cooler has a stronger cooling effect, and the cooler quickly reduces the system temperature. Amplitude changes will cause the cooler to start and stop frequently, thereby reducing the life of the cooler; when the ambient temperature is high, the cooling effect of the cooler is weak, and the cooler must reach the corresponding temperature to start the corresponding number of coolers, and the system temperature adjustment is relatively difficult. Slow; in addition, when the temperature is kept within a certain range for a long time, the running cooler will continue to run. Under this working condition, the wear degree of the cooler will be different, which is not conducive to the long-term stable operation of the entire cooling system.
