介绍了一锅炉热管空气预热器改造项目中自行设计研制的热管热真空制作技术及装置，并将该批研制的热管性能与以前本课题采用机械真空法所研制的热管性能进行对比测试，发现其等温性大有提高，性能衰减速度大降。同时，分析指出了该方法改善热管性能原因。
This paper introduces the technology and equipment of heat pipe thermal vacuum fabrication which is designed and developed by ourselves in the project of heat pipe air preheater retrofit of a boiler and compares the performance of the heat pipe developed in this batch with the performance of the heat pipe previously developed by using mechanical vacuum method. Its isotherm greatly improved, the performance decay rate dropped significantly. At the same time, the analysis pointed out that the method to improve the performance of heat pipe.
