Fluid selection and property effects in single and two-phase immersion cooling (electronic components)

Abstract

The governing equations for liquid and two-phase heat transfer are used to derive fluid figures-of-merit (FOMs) for liquid-forced and natural convection, boiling incipience, and critical heat flux in both pool and flow boiling modes. These FOMs are given to help evaluate and compare the thermal performance of several candidate immersion cooling fluids. In addition, the governing equations are used to determine the sensitivities of thermal performance to fluid property values.<>
