Abstract

This NASA SBIR project will develop modular spray-cooled assemblies that satisfy NASA power and mass budgets and can be scaled to cool multiple heat sources subjected to high heat fluxes and microgravity conditions. Much of the work on spray cooling has been experimental in nature and technological improvements have been the result of extensive experimental work. There is a need for a better theoretical understanding. Power Electronics Leveling Solutions L.L.C. (PELS) analytical team has formulated mathematically the conditions for extracting high heat fluxes from a heated surface in addition to the latent heat of vaporization that takes place in the formation of the bubble under phase change. PELS has now the opportunity of combining its analytical and experimental capabilities to develop modular assemblies based on spray cooling with the goal of achieving heat fluxes in excess of 100 W/cm2 while satisfying power and mass budgets.
