Experimental Investigation on the Properties of the Capillary Phase-Change Material Thermal Storage Tank

Phase-change heat storage device is the key equipment for the heating technology´s application of solar heating technology, industrial waste, etc. Based on the analysis of the characteristics of the current phase-change heat storage device, the capillary phase-change material heat storage tank was proposed. And with a composite phase change materials, whose thermal properties were tested and the results showed that the composite phase change material meets the requirements of solar heating technology. Meanwhile, the effect of water flow and temperature to the capillary phase-change material heat storage tank were investigated and the optimum flow was got, which provides credible data for the design of the capillary phase-change material heat storage tank.
