Two-phase liquid cooling for electric vehicle IGBT power module thermal management

Abstract

The main goal of this work is to show the advantages of two-phase cooling technology for thermal management of high power electronics modules, with a SKIM909GD066 motor inverter as the test device for thermal/fluid analysis. Dissipated power, heat transfer coefficient and fluid temperature are set in a 3-D FEM (Finite Element Method) based thermal model to simulate two-phase cooling of IGBTs at the motor inverter. A comparison of two-phase cooling with single-phase cooling is made to address the advantages of the two-phase solution.
