基于电子风扇控制的混合动力客车散热器面积计算

摘要

混合动力客车配置电子风扇是发展趋势,但电子风扇的转速、扇叶直径、整车电流对冷却效果有较大影响。用传统方法匹配散热器,很难满足发动机的冷却需要。本文提出一种针对于电子风扇控制冷却的散热器散热面积计算方法。%Hybrid electric bus configures electronic fan is the development trend. But the electronic fan speed, fan blade diameter and vehicle electric current have greater influence on the cooling effect. Using traditional methods of matching radiator, it is difficult to meet the need of engine cooling. The authors present a calculation method of radiator area by electronic fan control cooling.
