Abstract:
The possible improvement of the thermal impedance by direct and indirect immersion cooling of power semiconductor chips in different liquids is investigated. The non-linear behavior of the thermal impedance in the case of boiling is modeled and can be used to increase the power density or lifetime. In addition, the results of a 3D CFD simulation are compared with the laboratory measurements.
