文摘

PCMs loading with graphite nanoplatelet (GNPs) composite was applied to IGBT thermal management. Thermal conductivity of the composite was measured to increase by nearly 5-fold for the GNPs loading of 15%. GNPs loading can effectively increase the dropping temperature from 55 C to 165 C, primarily due to the increased effective surface area.
