Integrated single and two-phase micro heat sinks under IGBT chips

Abstract

Experiments have been performed to assess the feasibility of single and two-phase micro heat exchangers applied to the cooling of IGBT power components. After a brief recall of the principal characteristics of such heat exchangers, prototypes that have been built and tested are described. Experimental measurements are then compared to the predictions of the thermal and hydraulic performances with water and the inert fluorocarbon liquid (FC72) as coolant fluids.
