摘　　要：指出了当前全玻璃真空管集热器在结构上的不足,为了提升集热器的热效率,加入内插管的方式改进真空管集热器的结构。设计了两套实验系统,一套是未改装过的,另一套是改装以后的,在相同的环境下做对比实验。通过改变下降管的长度,设计三套实验方案,对每套方案的实验结果进行了分析,实验表明这种改造方法是完全可行的,但是需要进一步完善结构。In this paper, It point out the shortages in the rencent evacuated tube solar heat collector. In order to promote the efficiency of the collector, by using the manner of inserting another tube in the middle of the vacuum tube to change the structure of the collecter better. Design two experiment systems, one of them isn＇ t modified, while the other one is changed his custome, and they are tested comparatively in the same environment. By changing the length of decline tube, three sets of experiment methods are designed. After analyzing the results of the experiments, it indicate that this alteration method is entirety feasible, but the system need further improvement of th structure.
