Two-phase Fluid Selection for High-temperature Automotive Platforms

Abstract

High-temperature environments and device self-heating are pushing the thermal limits of power electronics. This is particularly true in automotive applications, where there is a transition from internal combustion architectures to hybrid electric and full electric vehicles. In general, two-phase cooling has emerged as an attractive solution to meeting the high-temperature, high-power cooling needs of the aforementioned electronics. However, it is important to understand the benefits and limitations of various fluids when designing a two-phase cooling system. To aid in the selection process and add to the current knowledge base, this report briefly discusses the current state of high temperature electronics, reviews platform considerations when selecting a fluid, and introduces a two-phase Figure of Merit (FOM) to analyze over 110 different fluids for cooling high-temperature electronics up to 500 deg C.
