直流充电机设计过程中IGBT功率模块的散热设计非常关键,介绍了一种适合直流充电机工程应用的IGBT功率模块损耗计算公式。通过Icepak软件建立直流充电机水冷散热模型,仿真分析不同入水口流速、不同冷却介质、不同入水口水温对散热器散热效果的影响,得到的散热数据和规律曲线可为直流充电机产品水冷散热优化设计提供理论依据。

The heat dissipation design of IGBT power module is very important in the design of DC charger.A formula for calculating the loss of IGBT power module suitable for the application of DC charger engineering was introduced.The water cooling heat dissipation model of DC charger was established by Icepak software.The effects of different inlet velocity,different cooling medium and different inlet water temperature on the radiator heat dissipation effect were simulated and analyzed.The heat dissipation data and regularity curve obtained by simulation could provide theoretical basis for the optimal design and development of water cooling heat dissipation of DC charger products.
