摘要

本文采用CFD分析方法对48V/ 35kw GaN场效应管双三相逆变器的液冷散热器进行了设计研究。利用氮化镓场效应管，可以在电力电子元件中实现更高的功率密度，从而产生更高的热密度。为了找到一个最佳的散热器配置，研究了两种不同配置的冷板的冷却性能，并与市售冷板进行了比较。并对温度场、压力场和流体速度场的分布特征进行了比较分析。

Design Investigation of Liquid Cooled Heat Sink for GaN FET Dual-Three Phase Inverter

This paper presents the design investigation of liquid cooled heat sinks for a 48V/35 kW GaN FET dual three-phase inverter using CFD analysis. With the use of GaN FETs, higher power density can be realized in power electronics components which results in higher heat density as well. In order to find an optimal heat sink configuration, the cooling performance of two different configurations of cold plates is investigated and compared with commercially available cold plate. And the distribution characteristics of the temperature, pressure and fluid velocity field are compared and analyzed.
