Taking the forced air-cooled radiator of an electric vehicle motor controller as the research object,the simulated heat source is introduced to solve the influence of junction temperature characteristics on the experiment during the stalled rotor test of power devices.Tthe heat dissipation performance test system of the radiator is developed,and the influence of the inlet wind speed of the radiator on the heat dissipation performance under this working condition is tested.On this basis,the experimental data results are used as the parameter input of the simulation model to analyze the global temperature field distribution of the heat sink system,which provides a basis for the performance analysis and optimization design of the heat sink.
