Simulation of Enhancing Heat Storage Performance of Air-type Phase Change Energy Storage Device with Fins
In order to solve the problems of long heat storage time for air-type phase change energy storage devices,optimization measures for the heat storage performance of the devices were studied.The temperature field of air-type phase change energy storage devices with fins of different volume fractions,thicknesses and heights was simulated by fluid dynamics simulation software FLUENT.The results showed that when the volume fraction of the fins is 15％,the thickness of the fins is 8 mm,and the height of the fins is 14 mm,the shortened heat storage time of the air-type phase change energy storage device was most,which can be shortened by 46.97％.This showed that the addition of fins promotes the melting of phase change energy storage units.By optimizing fin volume fraction,thickness,and height parameters,the heat storage performance of air-type phase change energy storage devices can be improved.
