摘　　要：对内聚光膜式全玻璃真空太阳集热管进行了9组烘烤排气实验,通过对比各组集热管在烘烤排气过程中的排气量及分析高温烘烤———加速老化实验数据,得到了其烘烤排气最佳工艺参数。9组实验中,450℃/50 min,450℃/40 min,450℃/30 min及400℃/50 min四个工艺制作的集热管真空品质相差不多,优于其余五个工艺;单从集热管真空品质角度看,450℃/50min烘烤排气工艺最好,若从真空品质和制作成本两方面考虑,400℃/50 min是较好的工艺参数。The impacts of the degassing conditions,the baking temperature and time,on the quality and fabrication cost of the all-glass solar collector tubes,the inside walls of which were coated with sunlight concentration membrane,were experimentally evaluated to optimize the baking-evacuation process on industrial scale.The results show that the baking temperature and time strongly affect the tube quality and production cost.For instance,when it comes to high quality of the tubes,the optimized baking evacuation conditions were found to be the 450℃/50 min process.We suggest that a compromised baking evacuating process,400℃/50 min.Minimize the production cost and ensure high quality of the tubes.
