摘要/Abstract

摘要： 水合无机盐具有适宜的相变温度、较大的相变潜热、原料廉价以及热导率较高(相对有机相变材料而言)等优势而有望成为中低温热利用领域理想的储热材料。然而,水合盐具有过冷、相分离和液漏等缺陷,一直以来成为限制其应用的瓶颈缺陷。水合无机盐作为相变储热材料的传统研究主要集中在成核剂和增稠剂的选择上,近几年一些研究者开始研究水合无机盐复合或封装工艺,极大地促进了水合盐性能提升方面的工作。本文综述了常见的几种低温类水合无机盐过冷和相分离现象的解决方法以及基于这几种低温水合无机盐的复合相变储热材料的研究,复合相变材料较单一纯相变材料具有诸多优越的性能,预测采用多孔材料吸附封装技术或微胶囊封装技术来制备水合无机盐复合相变材料可能成为未来解决水合盐液漏问题的研究热点。

Abstract: With the advantages of proper phase change temperature,high latent heat,cheap raw materials and high thermal conductivity (compared with organic phase change materials),the inorganic hydrated salts are considered as ideal heat storage materials in the field of middle and low temperature heat utilization. However,the hydrated salts have also defects of supercooling,phase separation and leakage,which have significantly limited their applications. The traditional researches on hydrated salts focused on the choice of nucleating agents and thickening agents. Recently,some researchers on the composite or encapsulation of inorganic hydrous salt showed up,greatly promoting the work of improving the performance of hydrated salts. In this paper,the solutions for supercooling and phase separation and the researches on phase change composites of several common inorganic hydrated salts are summarized. Compared with single phase change materials,the phase change composites have many superior properties. Preparing inorganic hydrated salts phase change composites with porous materials package and micro encapsulation technology may become the research hotspots for solving the problem of inorganic hydrated salts leakage in the future.
