An effective thermal conductivity model for architected phase change material enhancer

Romain Hubert, Olivier Bou Matar, Jerome Foncin, Philippe Coquet, Dunlin Tan, Hongling Li, Edwin Teo, Thomas Merlet, Philippe Pernod

Abstract Phase Change Materials (PCM) have been widely used for thermal energy storage due to their high latent heat of fusion. However, PCMs suffer from their very low thermal conductivity which limits heat spreading around the heat source. Without proper thermal conductivity enhancement, melting…
