摘　　要：本文设计了一种新型基于微热管阵列的低温相变蓄冷装置,通过实验研究和数值模拟系统分析其性能优势。研究结果表明,该装置具有良好的均温性,微热管阵列表面的平均温差不超过3℃。相较于增加传热流体的流量,降低其进口温度能更有效提升装置的传热效率。相比于相同体积的直翅片装置,所设计的Y型翅片式蓄冷装置蓄冷时间缩短13.7%,单位体积蓄冷量提高14.2%,且乙二醇溶液相变时温度分布更加均匀。This article presented a novel low-temperature phase change cold storage device based on a micro heat pipe ar-ray.Through experimental research and numerical simulation,the significant advantages of the device in multiple performance in-dicators were revealed.The results show that the average temperature difference on the surface of the micro heat pipe array does not exceed 3 C,demonstrating good temperature uniformity.Compared to increasing the flow rate of the heat transfer fluid,re-ducing its inlet temperature can more effectively improve the heat transfer efficiency of the device.Compared to straight finned de-vices of the same volume,the designed Y-shaped finned device reduces the cold storage time by 13.7%,increases the cold storage capacity per unit volume by 14.2%,and has a more uniform temperature distribution.
