摘　　要：以电传动履带车辆为研究目标,根据机械类和电子类热源部件工作温度不同的特点,设计了高低温双循环水路分别进行冷却散热,高温循环水路冷却机械类热源部件,低温循环水路冷却电子类热源部件,并通过对车辆常用工况和最大热负荷工况时的冷却系统性能参数进行了计算,计算内容包括:高低温循环冷却水路最大散热量、散热器迎风面积、空气流量、冷却水流量、散热器散热面积,并把计算结果与选型排风扇和选型水泵试验数据进行了匹配,计算结果表明:电传动履带车辆采用高低温双循环水路冷却热源部件的技术可行,满足车辆不同行驶工况下的冷却散热要求。Based on different operation temperatures of the mechanical and electronic components in an electric drive tracked vehicle,the cooling system which has high and low temperature double-circulation loops was designed.And the double circulation loops work separately,of which the high temperature circulation loop is for mechanical components and the low temperature circulation loop is for electronic components.The following calculations are carried out： the peak radiating heat amount in the high and low temperature circulation loops;the windward area;the air flowing amount;the cooling water flowing amount;the radiating heat area of the radiator in the case of the usual operating condition and the maximum heat load one.The calculation results were matched with the performance experimental data of the selected fan and water-pump.The results indicate that the cooling scheme with the high and low temperatures double-circulation loops in the electric drive tracked vehicle is feasible and satisfies the radiating heat requirement under different driving cycles.
