Summary:

In hybrid electric vehicles, the inverter is a critical component in the power module, which conditions the flow of electric power between the AC motor and the DC battery pack. The inverter includes a number of insulated gate bipolar transistors (IGBTs), high-frequency switches used in bidirectional DC-AC conversion. The heat generated in IGBTs can degrade performance, reduce lifetime, and cause component failures. Heat fluxes as high as 250 W per square centimeter may occur, which makes the thermal management problem quite important. In this paper, the potential of self-oscillating jets to cool IGBTs in HEV power modules is investigated experimentally.
