摘　　要：本文采用数值模拟的方法研究了盘管式蓄冷板的融化过程,分析了管道的偏心距和肋片尺寸对融化过程的影响。研究表明,随着偏心距的增加,融化速率加快。肋高越大,蓄冷板的融化速率越大,而肋宽对融化过程的影响可忽略不计。添加肋片减小了蓄冷板的最大释冷量,而改变偏心距并未改变蓄冷板的最大释冷量,且不同情况下的释冷量与液相率大致成线性相关。In this paper,a numerical simulation method was employed to investigate the melting process of a coil-type cold storage plate.The effects of eccentricity distance and fin size on the melting process were analyzed.The results indicate that an increased eccentricity distance accelerates the melting rate.Higher fin height leads to a faster melting rate of the cold storage plate,while the influence of fin width on the melting process is negligible.The addition of fins reduces the maximum cooling release capacity of the cold storage plate,but altering the eccentricity distance does not affect the maximum cooling release capacity.Moreover,the coling release capacity under different conditions is approximately linearly correlated with the liquid fraction.
