大功率电力电子器件相变冷却技术的实验研究
Experimental study on phase-change cooling techn ology in high power electronic devices
摘要
Abstract
More and more attentions are paid for the heat dissipation problem of Megawatt-class converter IGBT since it has been the bottleneck in the development of integrated large capacitors.This paper presents an experiment in which two kinds of IGBT module cold plates are designed, one normal and the other with heat transfer enhancement respectively.The temperature distributions of the two kinds of cold plates were simulated numerically, and the per-formances also turned out by using self-built experimental platform.The two kinds of different structural cold plates could satisfy the requirements of the power device junction temperature, and which of the heat transfer enhancement cold plates showed lower than 5 K with more uniform temperature distribution.In the power of 3 000 W and 4 000 W,the temperature of cold plates read 56.6℃and 59.5℃,which provided guidance for system structure de-sign.关键词
