Abstract: The “FLAT TERMO-SOLAR COLLECTOR AND MANUFACTURING PROCESS”, subject of this patent, represents a radical paradigm shift, both in the manufacturing process—whose steps were minimized and subject to any degree of automation—and regarding the shape design of the solar energy gathering tubes and tightness of the metal housing that houses the collecting element. The solar energy gathering tubes in accordance with this patent are manufactured with copper and have reduced costs—as the materials, shapes and manufacturing process—due to three innovative embodiments: 1. The reducing the thickness of the copper plates to only 0.10 to 0.15 millimeters, which reduces the cost of materials and the final weight of the assembly; 2. The molding of the gathering tubes by its stamping in these thin plates, which provide structural stability to the thin plates, thereby balancing the brittleness of their low thickness with increased resistance conferred by stamping; 3.
