摘要: 水合盐相变储能材料具有相变温度适中、导热系数大、潜热值高、价格低廉等优点,因而具有广阔的使用前景。然而,过冷、相分离、循环稳定性差等诸多问题限制了水合盐的实际应用。许多学者将水合盐与其它材料结合,构成复合相变材料,成功地解决了以上问题。前人对水合盐复合相变材料的研究以解决水合盐在使用过程中的上述问题居多。然而近年来,有研究者制备复合相变材料以改善水合盐的热物性,如相变温度、导热系数、潜热值等,取得了一定成果,但这一研究思路仍需进行进一步探索。文章将制备水合盐复合相变材料的目的作为线索,总结了水合盐复合相变材料的研究思路,详细介绍了国内外相关的研究工作和研究成果,并指出了今后水合盐复合相变材料的研究重点。

Abstract: Hydrated salt-based phase change materials have several advantages including moderate phase transition temperatures, high thermal conductivity, high latent heat and low prices, and hence a potential for a broad range of applications. Such materials, however, often come across problems including supercooling, phase separation and poor cycling stability, which limit their practical applications. One way to resolve the problems are the combination of the hydrated salts with other materials to form composites. This has been proven highly effective. Recent years also see researchers to use composite phase change materials as a mean to improve thermal properties of the phase change materials, including phase transition temperature, thermal conductivity and latent heat etc. This paper summaries recent progress in the area.

Key words: hydrated salt, composite phase change material, supercooling, phase separation, cycling stability, thermal properties
