本文讨论了水—碳钢热管的相容性问题。分析了金属腐蚀的基本原理并据此提出了解决水—碳钢相容性的措施:管壳钝化处理,缓蚀浸泡、工质中添加缓蚀剂以及沸腾排气法等。测定了实验热管的性能,包括起动温度、起动时间、温差水平以及传热性能等,取得了理想的结果。在寿命实验中持续运行了5000小时以上,未发现任何明显变化。 This article discusses the compatibility of water-carbon steel heat pipes. The basic principle of metal corrosion is analyzed and the measures to solve the compatibility of water - carbon steel are put forward accordingly: passivation of shell and tube, corrosion and immersion, addition of corrosion inhibitor in working fluid and boiling exhaust method. The performance of the experimental heat pipe was measured, including the starting temperature, the starting time, the temperature difference and the heat transfer performance. The ideal results were obtained. In the life of the experiment continued operation of more than 5000 hours, did not find any significant change.
