【摘要】 燃料电池具有高效率、无污染、高可靠性的特点,汽车上广泛使用的是质子交换膜燃料电池。但燃料电池产热量大,产热部件多,且发动机舱内空间有限,导致散热困难。因此,本文选取某燃料电池汽车为研究对象,搭建GT-COOL和STAR-CCM+联合仿真平台。使用一维和三维模型联合计算150km/h工况下发动机舱内的温度特性,并找到主要热害部件。通过调整主散热器和风扇之间的距离来降低热害部件的表面温度,计算结果表明调整之后的温度特性达到了优化发动机舱内温度分布的目的。对于实车发动机舱内部件的设计与布置具有一定参考价值。更多还原

【Abstract】 Fuel cells have the characteristics of high efficiency,environmental friendly and high reliability.Proton Exchange Membrane Fuel Cell(PEMFC) is the most widely used power source in automobiles.However,fuel cells have large amount of heat dissipation in many different components.Meanwhile engine compartment space is limited by dimensions.Hence it is difficult to dissipate heat.This paper used fuel cell vehicle as research target and built joint simulation platform with GT-COOL and STAR-CCM+.Then analyzed surface temperature of different components in 150 km/h and decreased surface temperature by adjusting distance between radiator and fan.The simulation result revealed temperature characteristics has reached the optimization target.It is a valuable reference for the design and layout in practical engine compartment.更多还原
