摘　　要：相变储热是储能领域的重要组成部分,它可以解决热能供求在时间和空间上不匹配、以及间歇性、波动性等问题。由于相变材料导热系数较低,限制了其大规模应用于储热领域。热管与相变材料耦合是有效强化相变储热的方法。总结热管与相变材料的不同耦合方式以及在不同应用领域的研究进展,分析热管与相变材料不同耦合方式的优势和潜力。研究发现相变材料与热管的耦合能够强化储热系统储/放热性能,另外相变材料与热管在不同位置耦合能够实现不同的功能。但是相变材料与热管耦合传热机理还不明晰,还需增强基于热管的储热系统对动态工况的适应能力,拓宽优化其应用范围。Phase change thermal storage is a crucial component of the energy storage sector,as it can address the mismatch between heat supply and demand in time and space,as well as intermittency and fluctuation issues.The low thermal conductivity of phase change materials limits their large-scale application in the field of thermal storage.Coupling heat pipes with phase change materials is an effective method to enhance phase change thermal storage.The different ways of coupling heat pipes to phase change materials and the research progress in different applications are summarized,and the advantages and potentials of the different ways of coupling heat pipes to phase change materials are analyzed.It is found that the coupling of phase change materials with heat pipes can enhance the charge/discharge thermal performance of storage systems,moreover,coupling phase change materials with heat pipes in different positions can achieve various functions.However,the heat transfer mechanism of the coupling between phase change materials and heat pipes is still not clear,and there is a need to enhance the adaptability of the heat pipe-based thermal storage systems to dynamic conditions,to expand and optimize their range of applications.
