In this study a cooling technology based on a two-phase-change of a working fluid is presented. By help of special micro structured heat transfer surfaces, the boiling rates increase compared to unstructured surfaces. Large amounts of heat up to several kilowatts can be removed by intense boiling of the working fluid, also with small surface areas. For the generation of appropriate micro structures, different micro manufacturing technologies can be applied, demonstrated in this paper. The presented results of systematic experiments show the capability of this cooling technology for power and high-power electronics.
