摘　　要：文章研究对象为汽车散热器。通过CFD仿真分析,得出散热器的进出口管口设置在不同位置时散热器的内部流动阻力和流量分布均匀性的区别。基于CFD研究结果,通过制作不同进出口位置散热器的手工样件在台架进行测试,得到不同管口设置的散热器的实测性能区别。结果表明:当进出口水管位置设置不合理会对散热器水阻带来翻倍的影响。通过CFD研究和样件实测,为指导汽车散热器的进出口水管位置设计提供了优化方向。In this paper,the research object is the automotive radiator.According to CFD analysis,we get the result that the internal fl ow resistance and fl ow distribution will be different when we set different inlet and outlet port position.We make two typical prototype samples to do the bench test based on CFD result,and we get different test result due to different inlet and outlet port position.The test result indicates that when the position of inlet and outlet port is set improperly,the impact on internal fl ow resistance will be significant.Through the comparison and analysis of CFD and test data,the optimization direction is provided for guiding the detailed structure design of inlet and outlet port position for automotive radiators.
