ES266981U - A perfected collector of solar radiation. (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

An improved collector of solar radiation, of the type comprising a solar energy absorption plate, in contact with a tubular carrier of a fluid receiving the absorbed energy, mounted in a box of thermal insulating material and under a transparent protective cover the solar thermal radiation, essentially characterized in that said cover is shaped like a hat, serving as a roof for the rainwater, preventing it from penetrating into the interior; by the fact of incorporating a rubber sealing profile that rides on the edge of the box eliminating the possibility of moisture and friction entering the cover with the box, facilitating dilatations; because the clamping system of the cover is made by pressure, with the help of a stainless steel closing jig; because the absorption silver is configured in such a way that, practically reaching the closing frame, it captures all the solar radiation incident on the collector without said radiation encountering isolation zones, for which, the sides of said plate are extended in a fold that covers the heat insulating bands of the carrier box, thereby increasing the absorption efficiency per unit area of the collector; and because the cover is constituted by two layers, the interior parallel to the absorber plate and forming a chamber between them, constituted by a laminar structure, while the exterior, which rests on the first, forms a corrugated structure forming a succession of cameras, whose undulation leads to a minimum accumulation of dust on the cover, thus reducing the loss of performance due to this cause.
