Abstract

PURPOSE:To solve the danger of implosion, which is the problem awaiting solution in a conventional solar heat collector, the increase in weight due to the thick glass wall of a transparent vacuum tube, higher cost and the like by a structure wherein an absorber pipe is inserted in the transparent vacuum tube, the outer surface of which is covered with flexible transparent resin film. CONSTITUTION:The outer surface of a transparent vacuum tube 1 made of glass or the like is covered with transparent resin film 4 having excellent weatherability and light transmittance such as polyethylene, polycarbonate, polyvinyl chloride, fluoride resin or the like. If the transparent vacuum tube 1 is broken by impact force from outside, the implosion phenomenon occurs due to the vacuum pressure within the tube 1 and the broken pieces of glass tend to scatter. However the transparent resin film prevents the pieces from scattering. Accordingly, the safety at implosion can be satisfactorily kept, even when the wall thickness of the transparent vacuum tube 1 is made thinner than ever.

The cylindrical body, 12 is a heat collecting tube, and 13 is a heat collecting plate. Since this solar heat collector is composed of glass tubes that are kept in a vacuum state with an internal vacuum level of 10-3 to 10-5, it is susceptible to various external impact forces during transportation, construction, and after construction. There was a risk of implosion damage. To that end, remove the inside of the vacuum transparent cylindrical body 11 and remove the dimensions. There were problems such as the top being heavy, making it difficult to construct, and increasing costs.

爆縮時の安全性を保つこ吉がてきる。When the vacuum transparent cylindrical body 1 is damaged due to an external impact force, an implosion phenomenon occurs in the internal vacuum pressure and fragments tend to scatter, but this is prevented by the transparent resin thin film 4. Therefore, even if the wall thickness of the vacuum transparent cylindrical body 1 is made thinner, safety in the event of implosion can be sufficiently maintained.
