Direct Cooling of Propulsion Drives for High Power Density and Low Volume

摘要

This final report summarizes the research work and conclusions related to ONR Award N00014-01-1-0634 under the DoD DESPCoR Program. The main objective of this grant was to investigate the feasibility of using spray cooling as the thermal management technology for power semiconductor devices used in power converter applications. this report covers the following: Basics of spray cooling, a novel power packaging methodology for power semiconductor devices that is compatible with spray cooling, the design of a power module serving as a technology demonstrator, and laboratory experimental results. Initial results seems to be superior to other approaches like cold-plate cooling.
