摘要

提出一种光伏直驱式电热相变蓄热墙板供暖末端

利用光伏直流电驱动电热膜产热供暖

同时将热量储存于相变材料中。利用多物理场耦合软件COMSOL建立其传热模型

探讨在自然对流条件下添加平直翅片（翅片间距、长度及厚度）对相变蓄热墙板传热过程的影响。研究结果表明：适当减小翅片间距能够有效缩短相变材料的完全熔化时间

提高平均蓄热速率

且延长放热时间

但影响不甚明显

当翅片间距小于25 mm时

总蓄热量显著下降;相同翅片间距下

翅片长度占据相变材料径向长度的比例越大

蓄热速率越高;厚度为1 mm

平均蓄热速率达到最大103.3 kJ/h

相较于无翅片结构增幅达27.2%。

Abstract

A panel heating terminal with photovoltaic direct drive electric heating phase change heat storage wall panel heating terminal is proposed

which uses photovoltaic DC to drive the electric heating film to produce heat and store the heat in the phase change material at the same time. The heat transfer model is established by using the multi physical field coupling software COMSOL

and the effect of adding flat fins （fin spacing

length and thickness） on the heat transfer process of phase change heat storage wall panel under natural convection conditions is discussed. The results show that properly reducing the fin spacing can effectively shorten the complete melting time of PCM

improve the average heat storage rate

and extend the heat release time

but the effect is not obvious. When the fin spacing is less than 25 mm

the total heat storage decreases significantly; Under the same fin spacing

the greater the proportion of fin length to the radial length of PCM

the higher the heat storage rate; When the thickness is 1 mm

the average heat storage rate reaches the maximum of 103.3 kJ/h

which increases by 27.2% compared with the structure without fins.
