A Review on Heat Transfer Enhancement of PCM Using Fin Tubes in Latent heat thermal energy storage (LHTES)
Keywords:
Shell and tube LHTS, PCM meltingAbstract
Due to its high heat storage density and practically constant temperature throughout the phase shift process, “latent heat thermal energy storage (LHTES)” is gaining popularity in the thermal energy storage area. However, the LHTES system is inefficient because of the low heat conductivity of “phase change material (PCM)”. The aim of this work is to provide a summary of the literature on improving PCM heat transfer by use of fin tubes. Using the fin structure to increase the heat transfer area is one of the most effective ways to boost the LHTES devices' heat transfer performance. In addition, this paper discusses the research done on how the fin location and fin shape affect the heat transfer performance of the heat storage unit.
