Performance Analysis of Pulsating Heat Pipe Solar Collector With Different Heat Storage Materials
摘要
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.关键词
