ES259443U - A solar flat collector (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Flat solar collector, of the type consisting of a box made of thermal insulation material with a face open to solar radiation covered by a material transparent to its energetic radiations and an internal placate of absorption thereof, transmitting said absorbed energy to a circulating fluid in a pipe in contact with said plate, characterized in that the absorber plate has a succession of channels formed by stamping, where the metallic tube carrying the thermal energy absorbing fluid is seated, presenting a high surface of energy transmission plate - absorption tube, whose absorption plate, frontal to the solar radiation is laterally angled up to the closing frame of the collector and presents, under the same and in all its extension, a reflective sheet, in order to an integral capture of the aforementioned energy without visible zones of isolation; because the cover of the collector is formed by two superimposed layers in transparent material to the solar thermal radiation, of which, the outer layer, undulated, constitutes the protective component of the dust accumulation and supports configuring a succession of cameras, on the inside, constituted by laminar double-chamber structures, which, in turn, forms a chamber with the absorption plate, said superposition of cameras integrating an insulating assembly that minimizes thermal losses by radiation from the collector to the outside; and because the inlets and outlets of the metallic absorption tube are arranged in the rear part of the collector box, connected by means of nozzles of the same metal, in order to make maximum use of the active space of the collector and to a maximum reduction of thermal losses by conductivity.
