Abstract
A solar absorber panel and method of making is disclosed in which a fluid heat transfer system of elongated hollow passages connecting inlet and outlet headers is fabricated of an array of two layers of strips of thin gauge stainless steel superimposed upon the reverse side of a mild steel absorber plate. The array of strips of thin gauge stainless steel is seam welded about the periphery of the strips and inflated to produce the hollow fluid passage system. The peripheral seam welding fixes the edges of the superimposed strips both to each other to seal the lattice fluid passage system and to the mild steel absorber plate. Inlet and outlet connectors fixed to the appropriate openings in the upper stainless steel lattice layer are also used for the inflation of the passage system. The construction of the solar absorber presents a corrosion resistant system which minimizes
