摘　　要：为了研究翅片换热器表面的结霜过程,本文搭建了结霜可视化试验平台,对不同迎面风速条件下的结霜过程进行了实验研究,分析了霜层质量,霜层体积和霜层密度随时间的变化规律。结果表明,霜层质量与霜层体积的变化趋势相近,均随结霜时间的增加呈增长趋势,并且在相同时刻下,随着迎面风速的增大而增大。与此同时,霜层密度在结霜过程中呈现递增趋势。In order to study the frosting process on the surface of the finned heat exchanger,a frosting visualization test platform was constructed to experimentally study the frosting process under different oncoming wind speed conditions,and the frost quality,frost volume,and frost density with time were analyzed.The results show that the changes of frost quality and frost volume are similar,and both increase with the increase of frosting time,and at the same time,they increase with the increase of the oncoming wind speed.At the same time,the frost density shows an increasing trend during the frosting process.
