Study On Combined Metal Absorber Glass Evacuated Solar Collector Tube And Its System

Because energy situation is extremely serious and environment is polluted heavily, the solar water heater is developed very well in our country. In order to develop them better, the paper designs a new kind of metal absorber solar collector on the basis of research status of the solar water heater. The collector is composed of a two-layer glass tube and a thin metal tube. What's more, the system consisting of the collector sets aside present quadrate connected cases so as to decrease its cost. On the other hand, the collector links with the case by the flexible substance in order to install and replace tubes conveniently.The paper tests one collector tube's performance and its system's everyday average efficiency, the result indicates that the one collector tube's performance should be not very good in comparison with all-glass evacuated solar collector tube, but its system's everyday average efficiency reaches the demand of national standard. Furthermore, the system can be used to heat living water, its utilization time is not limited, its system's cost declines a lot and its installation is very convenient. Therefore, the collector deserves popularization.
