Abstract

This paper reports the development and the thermal investigation of the performance of straight finned heat sink filled with paraffin/graphite nanoplatelets (GNPs) composite phase change material (PCM) for thermal management of insulated gate bipolar transistors (IGBT). The heat sink made of aluminum has a cavity where the composite PCM is stored. GNPs acts as an effective media of thermal conductivity enhancement (TCE), primarily aims to increase the thermal conductivity of paraffin. Differential scanning calorimeter (DSC) tests were done to investigate thermal properties which include melting and solidification temperatures and latent heats. The thermal conductivity of the composite increased by nearly 5-fold by the GNPs loading of 15%.
