This paper presents an analysis of the storage/release of thermal heat during melting and solidification of paraffin wax PCM (phase change material) with different composite of materials. In this composite material, the paraffin wax is characterized by high phase change latent heat and serves as the heat capacity promoter. Since the low thermal conductivity of PCM makes charging and discharging those system challenging on enhance the heat transfer and latent heat storage. In different geometric design used to enhance the heat transfer for addition of fins, use of straight tube, shell tube and encapsulation in this configuration mostly used for thermal storage system. Finally this paper discusses about heat transfer enhancement study using PCM at there different geometry and composites materials in an heat exchanger
