摘要

混合动力汽车的绝缘栅双极晶体管模块的下一代冷却技术的开发已经投入了大量的努力。两相冷却已被确定为此类模块冷却的潜在解决方案。本文探讨了两相冷却方案的可行性和实施，并与单相冷却方案进行了比较。本逆变模块采用由12对IGBT器件和二极管组成的丰田普锐斯逆变模块。采用热模拟技术研究了对流换热系数、冷板尺寸、总功率对IGBT的影响、热界面材料及其厚度对模块热性能的影响。

Thermal management of an IGBT module using two-phase cooling

A lot of effort has been put to develop the next generation cooling technologies for Insulated Gate Bipolar Transistor module of hybrid vehicles. Two phase cooling has been identified as a potential solution for cooling of such modules. This paper explores the viability and implementation of a two phase cooling scheme and its comparison with single phase cooling. For this inverter module of Toyota Prius consisting of 12 pairs of IGBT devices and diodes is used. Thermal simulation technique is used to study the effect of convective heat transfer coefficient, cold plate dimensions, total power on IGBT, thermal interface material and its thickness on the thermal performance of the module.
