摘要
通过传统热分析法和差示扫描热分析仪(DSC)研究了Na2SO4/SiO2复合材料的储热性能。研究表明Na2SO4/SiO2有很高的储热密度(180～210J/g)和良好的抗热震稳定性,得出了这种材料较完整的热工性能参数,为蓄热器的设计提供了必要的热工计算参数。
The thermal performance of a shape-stabilized energy storage material Na-2SO-4/SiO-2 is investigated. The thermal analysis by DSC indicates that the material is efficient in energy storage with the thermal energy storage density 180 J/g to 210 J/g, which is 1.5～2.5 times that of sensible ceramics, and is stable to thermal shocking.
