Design of control system for liquid cooling heat dissipation device
According to the performance requirements,device components and working principles of a liquid cooling heat dissipation device,a control system solution is pro-posed.The control system is designed in terms of electrical control,composition & layout,key programs,as well as alarm & protection procedures by analyzing the charac-teristics and action requirements of the controlled devices in the liquid cooling heat dissipa-tion device.The control system consists of a control unit and a distribution unit,with components such as relays,circuit breakers,and PLC controllers integrated into these two units.Under the operation of digital input/output modules,the start and stop control of devices such as compressors,circulation pumps,and solenoid valves are realized.Mean-while,under the operation of analog input/output modules,the adjustment of chilled wa-ter supply temperature,pressure,and PID controller is achieved.
