摘　　要：该文介绍了一种大型液压挖掘机液压马达风扇散热系统的温控系统设计方法,对风扇温控系统进行优化,在满足各散热器散热的前提下,使得风扇转速在工作过程中随各散热器冷却介质温度变化时以低转速运转,整机既节能又降噪。This paper introduces a design method of temperature control system for fan cooling system of hydraulic motor of large hydraulic excavator.The fan temperature control system is optimized.On the premise of meeting the heat dissipation of each radiator,the fan speed runs at low speed when it changes with the temperature of cooling medium of each radiator in the working process.The whole machine is energy-saving and noise reduction.
