摘　　要：相变蓄热具有蓄热密度高、蓄放热过程温度稳定和蓄热装置体积小等特点,具有较大的应用前景,但由于相变材料导热系数较小,严重影响了蓄热装置的蓄放热速率。因此,为提高蓄热装置的蓄放热性能,研究人员对此做了大量研究。该文对目前主要的蓄热方式和相变材料的特点进行了介绍,同时对相变蓄热强化换热技术的研究进行了深入的总结与分析,提出了目前相变蓄热装置存在的问题,并对未来研究方向提出建议。Phase-change heat storage has the characteristics of high heat storage density,stable temperature during the heat storage and release process,and small size of the heat storage device,which has a great application prospect.However,due to the small thermal conductivity of phase-change materials,the heat storage and release rate of the heat storage device is seriously affected.Therefore,in order to improve the heat storage and release performance of the heat storage device,researchers have done a lot of research on it.This paper introduces the characteristics of the current main heat storage methods and phase-change materials,summarizes and analyzes the research on the heat transfer enhancement technology of phase-change heat storage in depth,puts forward the current existing problems of the phase-change heat storage device,and proposes suggestions for future research directions.
