Abstract：

Microchannel heat exchangers of Al-alloy are the important component for air conditioner, of which the primary material is 3003 Al-alloy. In practical applications, the Al-alloy is suffered from corrosion and then results in the heat exchanger failure. This paper firstly introduces the corrosion problems existing in microchannel heat exchangers, then reviews the corrosion causes and influencing factors, such as coolants, micro-galvanic corrosion of the alloy and air pollutants etc., and summarizes corrosion control methods such as inhibitors and surface treatments. Finally elaborates some surface treatment techniques developed for 3003 Al-alloy, including electroless plating, anodizing, chemical conversion, sol-gel treatment etc., which probably provide references for the development and production of corrosion-resistant microchannel heat exchangers of 3003 Al-alloy.
Key words： microchannel heat exchangers    3003 Al-Alloy    corrosion resistance    surface treatment
