摘要
固-固相变储热材料在相变过程中无液体产生,而且具有较大的储能密度和较小的相变体积,在新能源开发和二次能源循环利用等方面具有显著的优势。本文综述了近几年来不同类型固-固相变储热材料的研究进展,包括石蜡、聚乙二醇、多元醇、聚乙烯、层状钙钛矿等,分别从相变行为特征,传热导热,储能机理及其应用等几个方面进行论述,并对相变材料目前存在的问题及未来发展前景进行了展望。
Solid-solid phase change materials （SSPCM） has become a new hotspot in the research of the energy development and utilization because of its large energy storage density, stable phase transition temperature, small volume change, no liquid leakage during phase change process. The research progress of SSPCM, such as paraffin wax, polyethylene glycol, polyol, polyethylene, layered calcium, were reviewed, the characteristics of phase change behavior, thermal conductivity, energy storage mechanism and its application were discussed.
