In order to meet the development requirements of modularization,integration,and automation of internal combustion en-gines,control the cooling water temperature of the internal combustion engine within a better working range,and simultaneously im-prove the comfort of product usage,a mode analysis of the control system for air-cooled radiators was conducted,and a centralized con-trol system for air-cooled radiators based on local area network monitoring was designed.Finally,the application effect of the central-ized control system was verified through experiments.The experimental results show that the centralized control system,through modu-larized and centralized control design,can accurately and efficiently control the cutting in and cutting out of the air-cooled radiator ac-cording to the temperature control requirements of the internal combustion engine,achieving automatic start and stop.The centralized control system can achieve local area network monitoring through Ethernet communication,with high real-time communication data,and can control the temperature within±2 ℃ of the target temperature.
