摘　　要：阐述了一种汽车热管理瞬态分析方法,即通过Radtherm和Fluent软件耦合计算得到某受热零件的温度随不同工况而变化的曲线,并通过计算结果与试验结果的对比,验证了瞬态热分析的可行性。最后采用该方法对某轿车前围板上的隔音棉进行了瞬态分析,并对隔热罩进行了改进设计,进一步降低了隔音棉的温度,减小了隔热罩的面积,达到降低成本,提高经济效益的目的。A transient analysis method for vehicle thermal management is presented. The temperature curve of a thermally-loaded part changing with different working conditions is calculated by coupling RadTherm with Fluent code, and then the feasibility of transient thermal analysis is verified by test. Finally the method is applied to the transient analysis of the isolation wool on the front bulkhead of a car, based on which the isolation shroud is modi- fied. As a result, the temperature of isolation wool is further lowered with the area of isolation shroud reduced, a- chieving the goal of cost reduction and better economical benefit.
