摘要/Abstract

摘要： 目前变流器装置中功率器件IGBT为最主要的热源,其对装置的安全运行产生一定的影响,其散热结构的设计很重要。以某一款IGBT为例,详细对其功耗进行了分析计算,对散热器设计方法进行了研究,用绘图软件SolidWorks对所设计的散热器进行立体建模,将其导入有限元分析软件Ansys,结合IGBT实际运行环境对所设计的散热器进行热仿真,对不同构型散热器的散热效果进行了对比,为IGBT散热器的设计提供了理论依据。在硬件平台进行实物验证,证实了仿真的有效性。

Abstract: The power component IGBT is the main heat source in the current-transformer equipment, the heat affects safe operation seriously, so the radiator design is very important. Taking a certain kind of IGBT as an example, the operating power consumption was analyzed and calculated, the design method of the radiator was studied, and the modeling of radiator with software of SolidWorks was designed, which was exported into the finite element analysis software of Ansys, making the thermal simulation combining the reality of IGBT operating environment, and comparing the cooling effect of different radiator configuration. A theory method was provided for the design of the IGBT radiator. An actual experiment in a hardware platform was carried on to confirm the validity of the simulation.

Key words: IGBT power consumption, radiator, thermal simulation, Ansys
