摘　　要：本文利用STAR-CCM+流体仿真软件,完成了四种工况下热管理集成模块剂侧传热仿真及试验。工况一、二为单独测试冷、热流体通过剂侧板与环境的换热。冷流体温升1.5℃@2.2 lpm;热流体温降0.5℃@9.2 lpm左右;工况三冷流体温升5℃@1.1 lpm;热流体温降0.6℃@4.2 lpm左右;工况四冷流体温升5℃@2.2 lpm;热流体温降0.8℃@9.2 lpm左右。通过试验与仿真对标,在不同温度及流量下,出口温度误差都控制在10%以内,满足工程使用。验证了仿真网格划分、湍流模型选择、换热系数设定及边界条件设置的正确性。In this paper,STAR-CCM+fluid simulation software is used to simulate and test the heat transfer on the agent side of the integrated thermal management module under four working conditions.The first and second conditions are to separately test the heat transfer of cold and hot fluids through the agent side plate and the environment.Cold fluid temperature rise 1.5℃@2.2 lpm;The heat flow temperature drops by 0.5℃@9.2 lpm;The temperature of the third cooling fluid rises by 5℃@1.1 lpm;Heat flow body temperature drop about 0.6℃@4.2 lpm;The temperature of the fourth cooling fluid rises by 5℃@2.2 lpm;The heat flow temperature drops by 0.8℃@9.2 lpm.Through the test and simulation calibration,under different temperature and flow,the outlet temperature error is controlled within 10%,which can meet the engineering use.The correctness of simulation grid division,turbulent model selection,heat transfer coefficient setting and boundary condition setting are verified.
