Abstract: 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.
