【 摘 要 】

For high power inverter, the internal temperature distribution directly affects its performance. In this paper, based on the finite volume method in Ansys Icepak, the temperature field and the flow field of a high power inverter are simulated and analyzed. According to calculating the power loss and heat dissipation of elements in the inverter, the temperature field and the flow field inside the cabinet under steady state operation are obtained. From the results of the simulation, the working temperature of component in inverter can be obtained and the performance of the cooling system of the inverter can be evaluated.
