电动汽车变流器用IGBT水冷散热器热仿真分析
Thermal analysis of IGBT water-cooling radiator for electric vehicle converter
摘要
Abstract
An IGBT water cooling radiator used in an electric vehicle converter was studied. Considering that the average Reynolds number of each channel was in the transition region, steady state temperature of the radiator was calculated by using the laminar model, the standardk-ε turbulence model and six kinds of different low Reynolds number turbulence models with FLUENT software, respectively. Transient problem of the radiator was calculated by using self-developed model order reduction calculation program. Through verifying the accuracy of model order reduction method, transient thermal simulation of typical Chinese urban road conditions was carried out to obtain the temperature variation curves of each chip in IGBT device at different time. The results show that the heat dissipating performance of the water cooling radiator can meet the demand of typical Chinese urban road conditions.关键词
