摘　　要：低熔点合金具有导热系数高、储能密度大、使用温度范围广、性能稳定等特点,是一种潜在的宽温域传热工质和中低温相变储热材料。结合低熔点合金的相变温度、相变潜热、热导率及相变稳定性等热物理性能,综述了低熔点合金相变储热材料的研究进展;介绍了液态低熔点合金传热材料的蒸汽压、表面张力、黏度及比热容等性能,以及低熔点合金在高温下与容器材料的相容性;对低熔点合金传热储热材料的下一步研究进行了展望。Low melting point alloys are potential phase change thermal storage materials and heat transfer agent due to its excellent property such as high thermal conductivity coefficient, high thermal storage density, excellent thermal stability, low melting point and high boiling point. This paper review the phase change thermal storage low melting point alloys based on its thermo-physical properties such as phase change temperature, phase change latent, coefficient of thermal conductivity and stabilization. The steam pressure, interracial force, viscosity and capacity of heat are introduced to explore the application of low melting point alloy in heat transfer materials. The high temperature corrosion behaviors of low melting point alloy are also introduced. And finally, the future work about the thermal storage and heat transfer low melting point alloys are prospected.
