With the development of economy, the shortage of energy and environmental problems is increasingly prominent. Phase change energy storage technology can effectively solve the energy mismatch in space and time. Phase change cold storage materials are classified into organic materials, inorganic materials and composite materials, which usually have disadvantages such as high supercooling, severe phase separation and poor heat transfer performance. As a new heat transfer structure, pulsating heat pipe has the advantages of simple structure, high efficiency and economy. The physical model and the mathematical model of heat pipe cold storage are established and calculated by using pulsating heat pipe to enhance heat transfer. A movable heat pipe cold storage device was developed and experimental research was carried out. With the decrease of the cold source temperature, the pulsating heat pipe starts faster, liquefies and transfers the cooling capacity more easily, and the cooling time of PCM is shorter. With the increase of heat source temperature, pulsating heat pipe starts faster, evaporates and transfers heat more easily, and the cooling time of phase change material is shorter.

随着经济的发展，能源短缺和环境问题日益突出。相变储能技术可以有效解决空间和时间上的能量不匹配问题。相变蓄冷材料分为有机材料、无机材料和复合材料，通常具有过冷度高、相分离严重、传热性能差等缺点。脉动热管作为一种新型传热结构，具有结构简单、高效经济等优点。利用脉动热管加强传热，建立并计算了热管冷库的物理模型和数学模型。研制了一种活动式热管蓄冷装置并进行了实验研究。随着冷源温度的降低，脉动热管启动更快，更容易液化和传递冷量，PCM的冷却时间更短。随着热源温度的升高，脉动热管启动更快，更容易蒸发和传递热量，相变材料的冷却时间更短。
