摘要

为弥补太阳能具有间歇性的缺陷,将脉动热管应用到太阳能集热器中,设计了新型蓄热式脉动热管太阳能集热器。实验装置采用全玻璃真空管内放置脉动热管,同时添加储热材料,实现全天候持续提供能量。实验针对不同储热材料以及在有、无光照条件下集热器的传热特性进行对比分析,研究结果表明:储热材料为石蜡时,脉动热管当量导热系数提高了64.9%,热阻相对稳定,集热器最大集热效率为79.4%;储热材料为水时,热阻呈现先增大后减小的趋势,集热器最大集热效率为74.8%,最小热阻降低了24.8%,其最大热阻提高了61.2%。但从整体效果来看,当集热器输出热量达到50 W时,其热量输出稳定,储热材料为石蜡的集热器集热效果明显优于储热材料为水的集热器,且储热材料为石蜡时脉动热管当量导热系数要大于储热材料为水时脉动热管的当量导热系数。

Abstract

In order to make up for the intermittent problem of solar energy, a new regenerative pulsating heat pipe solar collector is designed by applying pulsating heat pipe to solar energy collector. The experimental device uses an all-glass vacuum tube to place pulsating heat pipe and add heat storage material to realize all-weather continuous energy supply. The heat transfer characteristics of different heat storage materials and collector with and without light are compared and analyzed in the experiment. When paraffin wax is used as the heat storage material, the equivalent thermal conductivity of the pulsating heat pipe is increased by 64.9%, the thermal resistance is relatively stable, and the maximum heat collection efficiency of the collector is 79.4%. When the heat storage material is water, the thermal resistance increases first and then decreases. The maximum heat collection efficiency of the collector is 74.8%, the minimum thermal resistance is reduced by 24.8%, and the maximum thermal resistance is increased by 61.2%. However, from the overall effect, when the output heat of the collector reaches 50 W, the heat output is stable, and the collector effect of the heat storage material is paraffin wax is significantly better than that of the heat storage material is water, and the equivalent thermal conductivity of the pulsating heat pipe is greater when the heat storage material is paraffin wax than that of the pulsating heat pipe when the heat storage material is water.
