The current trend for power electronics, electric motors and batteries is the increase in power density: higher powers are needed in smaller components. The increase in power results in an increase in thermal losses which combined with small volumes and surfaces, leads to high heat fluxes. To avoid overheating the electrical components, adequate cooling has to be applied. Cooling through immersion boiling (left figure) is a technique that can significantly increase the heat transfer and has promising solutions for many applications.
A setup is available to perform measurements on immersion boiling (right figure) of an electric vehicle power module. The goals of this master thesis are:
If the thesis is selected by two students, the following goals are added:
This project aids in achieving sustainable development goal (SDG) 7: affordable and clean energy, by enabling the replacement of fossil fuels by renewable electricity as an energy source for the transport sector.
