采用SEM和X射线能谱仪分析方法研究了50次热循环后Ba(OH)2·8H2O与铝合金和紫铜的相容性,发现Ba(OH)2·8H2O对铝合金有一定的腐蚀性,与紫铜具有优良的相容性.以简单的真空吸附填充方法制备了Ba(OH)2·8H2O/泡沫铜相变复合材料.搭建了含和未含泡沫铜相变储能装置实验台,对Ba(OH)2·8H2O/泡沫铜相变复合材料进行室温下稳态和瞬态的传热实验.结果表明:Ba(OH)2·8H2O/泡沫铜相变复合材料比纯Ba(OH)2·8H2O传热速率快,导热性能好,有效地降低了Ba(OH)2·8H2O的过冷度.高温恒温箱的传热实验表明:Ba(OH)2·8H2O/泡沫铜相变复合材料的蓄热能力随外界环境温度的升高而降低,当环境温度高于材料相变点温度时,应考虑对相变复合材料采取一些保温措施.
