摘　　要：|温控电比例变量液压风扇驱动系统与传统的定量液压风扇驱动系统相比,具有控制方式合理和节能的优点。通过原理分析和试验测试,探讨温控电比例变量液压风扇驱动系统的风扇转速的变化过程和节能机理。试验结果表明:温控电比例变量液压风扇驱动系统能够根据散热量的实际需求调整风扇转速,消耗功率的范围为1.6~27 k W,当环境温度低,散热量需求小时,由于风扇转速变低,消耗的功率也相应变小,节能效果更加突出。A variable displacement hydraulic system with thermal control power ratio for the fan drive system has better logic control and power saving when comparing with a traditional constant displacement hydraulic system. This project investigates into fan RPM variation process and power saving mechanism through principal analyses and tests.Results show that the former system can regulate the fan's RPM according to actual demand for heat radiating with a power consuming rate 1.6～27 kW. And more, when the ambient temp is low and the heat radiating demand is little the power consumption rate also becoming lesser for an outstanding result as the fan's RPM lowers.
