- Abstract
Experiments were employed by using the porous substrate as base material, and inorganic glass powder and sodium chloride (NaCl) as phase change material, respectively, based on melt infiltration method and bonded encapsulation, to investigate the best preparation process for the thermal storage samples. The microstructure and phase composition characteristics of the composite phase change thermal storage sample were studied, the mass loss rate of the composite phase change thermal storage material was analyzed, and the thermal storage performance and high-temperature compressive strength of the thermal storage sample were examined. The experimental study showed that, the composite phase change thermal storage material was developed by using the method of bonded encapsulation, adopting sodium chloride as the phase change material and cylindrical triangular pore honeycomb ceramic matrix with covers as the carrier, setting a temperature increase rate of 6.5oC/min, sintering temperature to 800oC and holding time of 30 min. The heat storage density of the composite phase change thermal storage material was 445.5 kJ/kg, and the high-temperature compressive strength of the thermal storage body was 75.9 MPa at 800oC, which had good heat storage and mechanical properties.
