- To reduce the energy use and emissions in the transport sector, electric vehicles are typically proposed as (part of) the solution. Power electronics are an essential part of electrical drivetrains for electric vehicle applications. Due to the high power density of these components, active cooling is a necessity to avoid overheating of the power electronic components. This study experimentally investigates two-phase cooling of an inverter base plate with a dielectric fluid (Novec 649). An Infineon inverter for a power range of 20 kW to 30kW is used in the experiments, where the base plat is horizontally in contact with a reservoir of dielectric fluid. Heat fluxes ranging from 6 kW/m² to 21 kW/m² were realised, which resulted in surface superheat temperatures of 8 °C to 15 °C. The fluid saturation temperature was varied in three levels (41 °C, 46 °C, 51 °C). Next to the surface temperature, the inverter substrate temperature was measured to evaluate the heat transfer path from the inverter substrate to the cooling fluid. The measurements show that for the low heat dissipation rates tested in this study, the substrate temperature reaches a maximal value of 70 °C. Extrapolation of the measurements to higher heat fluxes shows that the method is also feasible for medium loads, but that at the highest loads the heat flux will reach the critical heat flux which will result in overheating.
