| Abstract: | Solar photo-thermal utilization is one of the effective ways to solve the energy crisis and environmental problems. The
solar heat collector based on the form-stable composite phase change materials (PCMs) with high thermal conductivity can realize
the integration of heat collection, heat transportation and energy storage, which effectively realize the efficient solar photo-thermal utilization. Paraffin wax (PA) is used as PCMs, and expanded graphite (EG) is used as support material, thermal conductivity and light absorption additive. The EG/PA form-stable phase change heat storage solar collector is designed with high efficiency photo-thermal conversion, fast heat transport and high energy storage density. The Fluent software is used to simulate the change of energy flow density during the heat transfer process of the simplified solar collector model. The methods of experiment and numerical simulation have proved that the EG/PA form-stable PCMs has excellent heat transfer performance. The solar collector based on the form-stable composite PCMs performs well in the utilization of solar heat and shows great potential for heat utilization. |
