小功率车载逆变器的热仿真与实验研究
Thermal Analysis and Test of Small Power Car Inverter
摘要
Abstract
In order to explore the cooling performance of small power car inverter,a finite element 3D model was developed based on CFD simulation software.Then the heating situations of the whole and individual components of the inverter had been obtained through the numerical simulation calculation under different working conditions.On the basis of the numerical simulation results,the related experiments had been done under the same specifications of the numerical simulation.The test results showed the thermal characteristics of the components and the working temperature of the components was controlled around 100℃.Furthermore,the comparison between the experimental and numerical results showed that a quite accurate result could be received through the CFD simulation.The deviation from the experimental results was within 3.4%.Numerical simulation had high accuracy.关键词
