摘要

翅片管换热器的铜管与铝翅片之间容易发生电化学反应，在铝翅片表面形成一层三氧化二铝，增大换热器传热热阻，影响换热器乃至整个空调系统的性能。对翅片管换热器分别进行48 h和96 h的盐雾腐蚀实验，然后对腐蚀前后的实验样件测试其传热及压降特性，结果表明，翅片管蒸发器经盐雾腐蚀以后，其风阻变化在5 Pa以内，而换热量最多会降低12.5%，总的传热系数最多会减少16.6%，传热热阻最多会增加20%。

Abstract

Electrochemical corrosion takes place between the copper tube and aluminum fin of tube-fin heat exchanger easily，forming a high thermal resistance layer of Al2O3.Therefore，the performance of the heat exchanger and the entire air conditioning system will be affected.In this paper，48 h and 96 h salt spray corrosion tests were made on the tube-fin heat exchanger respectively.And the performance of the heat exchanger before and after salt spray corrosion was tested.It was found that the change of air pressure drop was less than 5 Pa.The capacity and overall heat transfer coefficient of the heat exchanger decreased by 12.5% and 16.6% after corrosion respectively.The thermal resistance of the heat exchanger increased by 20% at most.
