摘　　要：在汽车设计初期,为了更精确地计算前端风量,通过全尺寸风洞测试散热器风量,并运用仿真工具完成模型搭建与精度标定。发现散热风扇采用MRF或RBM仿真模型时,误差可控制在5%以内,符合工程应用要求。标定后的散热风扇模型通过在车型上实际应用,总结出一种散热风扇在整车环境下的性能匹配方法。At the beginning of vehicle design,this paper tests the radiator air quantity through a full-scale wind tunnel to calculate the front air quantity more accurately.It user the simulation tool to build and cali-brate the accuracy,which finds that the error can be controlled by less than 5%when the radiator fan uses MRF or RBM simulation model,the requirements of engineering application are satisfied.The calibrated ra-diator fan model is applied to the vehicle,and a method of fan performance matching in the vehicle environ-ment is summarized.
