The invention relates to a tractor radiator temperature control system and a fan rotating speed control method, the temperature control system comprises a plurality of radiators and temperature sensors, a silicone oil clutch is connected between a fan and an engine, and the fan rotating speed is controlled through a fan electric control unit. The combination rate of the silicone oil clutch is calculated by taking the outlet temperature of each radiator as a final control target, the upper limit adopts logic or control, the lower limit adopts logic and control, the intermediate value adopts a logic priority control strategy, the value is preferentially taken based on the air inlet temperature when the engine is in partial load, and the value is preferentially taken based on the water temperature when the engine is in full load, so that the phenomenon of unstable rotating speed is avoided; through the control of the ECU, the power consumption of the fan can be effectively reduced, the fan can work at any working point at the rotating speed, the severe fluctuation of the rotating speed of the fan cannot be generated in the fan control, and the working economy and stability of the tractor are effectively improved.

    本发明涉及一种拖拉机散热器温控系统与风扇转速控制方法,所述温控系统包括多个散热器和温度传感器,风扇与发动机之间连接硅油离合器,通过风扇电控单元控制风扇转速,以各散热器出口温度为最终控制目标计算硅油离合器结合率,上限采用逻辑或控制,下限采用逻辑与控制,中间值采用逻辑优先控制策略,在发动机部分负荷时优先基于进气温度取值,满负荷时优先基于水温取值,避免了转速不稳现象;通过ECU的控制,可有效减少风扇耗功,并能够实现风扇转速在任意工作点工作,风扇控制中不会产生风扇转速的剧烈波动,有效改善拖拉机工作的经济性和稳定性。
