The invention relates to a medium-temperature
solar heat collector. The medium-temperature
solar heat collector consists of a curved surface
metal runner, a communicating joint, high-temperature resistant
heat conducting glue, a vacuum
pipe, an insulation material, a
gasket, a
copper joint, a manifold, a main
pipe runner, connecting joints, a frame, an upper end cover and the lower end cover, and is characterized in that the high-temperature resistant
heat conducting glue is positioned at the lower part of the inner wall of the vacuum
pipe and the upper part of the curved surface
metal runner; the curved surface
metal runner is in the vacuum pipe; a metal runner blind plate is positioned at the lower end of the curved surface metal runner; the communicating joint is positioned out of the vacuum pipe at the upper end of the curved surface metal runner; the
gasket is positioned at the upper part of the communicating joint; the
copper joint is positioned at the upper part of the communicating joint; the manifold is positioned at the upper part of the
copper joint and the lower part of the main pipe runner; the main pipe runner is positioned at the upper part of the manifold; the connecting joints are positioned at two ends of the main pipe runner; the frame is fixedly surrounded by the vacuum pipe out of the vacuum pipe; the lower end cover is positioned at the bottom end of the upper part of the frame; the upper end cover is positioned at the upper end of the upper part of the frame; and the insulation material is below the curved surface metal runner in the vacuum pipe and in the upper end cover and the lower end cover of the frame.
