Claims

[Scope of utility model registration request]

(1) A heat medium tube is housed inside a translucent vacuum glass tube with both ends open, and the heat medium tube is axially sealed at the center of a sealing member that closes both openings of the vacuum glass tube. In the case where the tube protrudes through the vacuum glass tube, the outer peripheral wide mouth part of the funnel-shaped connection cap is welded to the end face of one opening of the vacuum glass tube, and one end of the heat medium tube is passed through the shaft seal at the central narrow mouth part of the funnel-shaped connection cap. The negative side of the opening of the cylindrical connecting tube is welded to the end surface of the other opening of the vacuum glass tube, and the gap between the other opening of the cylindrical connecting tube and the other end of the heat medium tube is 1. A heat collecting tube for a solar heat collector, characterized in that a bellows which can be expanded and contracted in the axial direction is interposed therein, and the other end of the heat medium tube protrudes through a shaft seal.

(2) Utility Model Registration Scope of Claims In the heat collecting tube of the solar heat collector according to claim 1, the material of the funnel-shaped connecting cap and the cylindrical connecting tube welded to the opening end face of the glass tube is the same as that of the glass tube and has a coefficient of thermal expansion. (e.g. F-31-42
6 alloy) for a solar heat collector.

(3) Utility Model Registration In the heat collecting tube of the solar heat collector according to claim 1, the bellows interposed between the open end of the cylindrical connecting tube and the outer periphery of the heat medium tube is connected to the cylindrical connecting tube. A heat collecting tube for a solar heat collector, characterized in that the tube is provided at a position farther from the open end of the glass tube than the glass tube.

(4) Utility Model Registration Scope of Claims In the heat collecting tube of the solar heat collector according to claim 1, the bellows interposed between the open end of the cylindrical connecting tube and the outer periphery of the heat medium tube is A heat collecting tube for a solar heat collector, characterized in that it is installed at a position that enters the inside of the glass tube from the open end of the tube.
