Abstract
In response to the problems of slow heat storage rate and long cycle of low thermal conductivity phase change materials,the fin enhanced heat transfer technology shows significant advantages.Based on the horizontal tubular heat storage unit structure,this paper optimizes the heat storage element by adopting the radial asymmetric arrangement of fins,and improves the thermal conduction performance.The results show that,with the increase in the number of fins,the melting rate of the phase change material significantly increases;compared with the uniform arrangement,the asymmetric fin arrangement(uniform on the top+dense on the bottom)can synergistically enhance natural convection and heat conduction;while only extending the length of the fins below in the radial direction,the heat storage capacity only decreases by 1%,while the heat storage rate significantly increases by 45%.关键词
