摘要
介绍了微通道换热器中存在的腐蚀问题,概述了包括冷却剂、合金相间电位差、大气污染物等腐蚀诱因和机理,并总结了缓蚀剂添加和基材表面处理等腐蚀控制手段;阐述了诸如化学镀、阳极氧化、化学转化、溶胶-凝胶处理等3003铝合金基材的表面防护技术,为耐蚀铝合金微通道换热器的开发和生产提供参考.
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 corro-sion 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-re-sistant microchannel heat exchangers of 3003 Al-alloy.
