Dynamic Simulation and Analysis of Heat Transfer Performance of Fin-Tube Cool Storage Device

摘要

According to the structural characteristics of the tube and heat transfer characteristics of PCM, model of the finned tube thermal storage system was developed, and heat transfer performance has been studied by numerically calculation. During charging and discharging process, we significantly analyzed the effects of fins, temperature of heat transfer fluid on freezing and melting characteristic, and compared different fin number effect on heat transfer enhancement. The results show that fin-tube can enhance the heat transfer performance of cool storage tank, and the best fin number of fin-tube is 32.
