Problems solved by technology

The heat collecting tube made in this way, when working, the temperature difference between the inner and outer tubes is large, and it is easy to cause tube explosion. In addition, the volume of the tube is too large, so it is not easy to heat
[0003] Although the solar collector tube used in trough solar collector power generation adopts the metal tube plus half-wing method or the heat pipe vacuum tube technology, the final heat absorption area and gas production are limited, and the sealing structure has no effect on the expansion of the material (transition metal). Strict coefficient requirements, high technical requirements for compatibility between glass and metal, although the hot press sealing process, low-temperature glass solder sealing process, flame melting process, and high-frequency melting process have been used. It seems that the reliability is insufficient, coupled with the difficulty of processing, high cost and maintenance, it is difficult to popularize in the domestic market, and currently only stays in research and development and small-scale government-supported projects
[0004] In the past 30 years, with the emphasis on energy in various countries, many scientific research institutes and some famous enterprises at home and abroad have laid a certain foundation in the field of medium and high temperature, but the key problem of "high heat, low Absorption rate, low utilization rate", "effective combination of glass and metal", "sealing and thermal expansion of different materials" and other problems plague the development of straight-through solar collector tubes, not to mention their wide application as functional components of buildings To the project integrated with the building

Description

technical field [0001] The invention relates to a straight-through solar heat exchange and heat collection device using solar energy as a heat source, and belongs to the technical field of medium and high temperature solar heat utilization. Background technique [0002] As we all know, most of the solar collector tubes widely used at present are double-layer glass tube structures with one end closed or straight-through glass inner tubes open at both ends. If double-layer glass tubes are used, the outer surface of the glass inner tube is coated There is a solar selective absorption coating, the working fluid is carried in the glass inner tube, and the vacuum is drawn between the glass inner tube and the glass outer tube. The heat collecting tube made in this way, when working, the temperature difference between the inner and outer tubes is large, and it is easy to cause tube explosion. In addition, the volume of the tube is too large, so it is not easy to heat. [0003] Alth...
