Method of fabricating a solar absorber panel
Patent
·
OSTI ID:5907377
A method of making a solar absorber panel is disclosed in which mild steel sheets are provided with a pattern of recesses such that when the sheets are superimposed, an internal hollow fluid heat transfer passage system is formed thereby including inlet and outlet manifolds joined by connecting passages. A metallic sealing material having a lower melting point than the sheets is placed in the recesses, the sheets are superimposed and the structure is peripherally welded to form a gas-tight envelope. The envelope is purged of air, partially internally evacuated and the edges of the internal passages sealed by heating the assembly above the melting point of the sealant material. The vacuum drawn on the envelope insures a tight seal between all passages as it allows external ambient air pressure to force the sheets together. The sealant material, which may be copper brazing rod or other material should be one which imparts a corrosion-free coated surface to the passages in addition to providing a tight seal to the unit.
