Research on Heat Storage-Release Property of Rectangular Array Tube Encapsulated Heat Storage Device

based on previous studies heat storage device structure was optimized and a rectangular tube array encapsulated phase change heat storage device was designed. Compared to sleeve heat accumulator, the heat transfer area was increased 2 times and phase change material thickness was reduced, which has greatly reduced the thermal resistance and improved the heat transfer coefficient. Thermal performance experiment bench of phase change heat storage device was built; heat storage performance experiment was carried on and the results were analysed.
