Title: Solar heat collector
Inventor: KAWAMURA HIROMITSU
IPC: F24S10/40
Filed: 1983-10-28
Abstract: PURPOSE:To improve the weatherproof property of sealing and welding part and make it employable for a long period of time by a method wherein the layer of glass powder, same as the glass outer tube in the material thereof, is adhered previously to a part whereat the outer tube of glass is welded to a metal for welding and thereafter the powder is heated to weld. CONSTITUTION:The part whereat the outer tube 1 of soda glass is welded to the metallic member for sealing and welding is interposed previously with a layer 9 of the fine powder (1-500m) of soda glass whereby the layer 9 of fine powder of same material as the glass outer tube 1 is molten easily and become flowable sufficiently and both of the members are welded rigidly by a good mutual diffusion between both materials of the metal 6 and the outer glass tube 1. Further, generation of too thick oxide film on the surface due to the excessive heating of the metal may be prevented by the existence of the glass powder layer 9. As a result, the phenomena of separation between the internal metal and the oxide film of metal may be prevented and the reliability of the collector may be improved remarkably.
