Advanced Boiling Cooling Technology Using a Compact Vessel with a Low Water Level

Abstract

There is a strong demand for compact cooling devices with high performance that is used for such as inverters of electric vehicles. Aiming for improving the performance of cooling devices with downsizing it, boiling heat transfer attracts a lot of attention because of its high heat transfer coefficient. However, there is few reports related to subcooled pool boiling using a compact vessel. In this study, to achieve a higher heat flux removing using a compact vessel, microbubble emission boiling (MEB) characteristics was investigated with a low water level, as well as nucleate boiling regime of subcooled pool boiling.
