摘　　要：功率逆变器作为常用电机驱动电源的核心部件由于其功率密度大、发热量多,对其热安全性的研究显得尤为重要。本文基于有限体积法,对电驱动用功率逆变器进行三维温度场分析,并在此基础上对散热模式和结构进行了分析探讨,所设计结构经仿真分析验证,具有良好的散热性能。在提高设计效率的同时,为功率逆变器散热结构的集成和优化设计提供了借鉴和参考。As the core components of electric drive power supply, the power inverter has high power density and more heat production, so it is important to study the thermal safety of power inverter. In this paper, based on the finite volume method, a new electric drive power inverter＇s thermal performance was analyzed and its thermal structure was analyzed and investigated using 3 D temperature field calculation. The designed thermal structure has satisfied heat dissipation performance, which validated by the simulation results. This study provided the basic reference for the integrated design and optimization of the thermal structure of power inverter, and improved the efficiency of design.
