Date Jun. 11, 1998The invention concerns a device for capturing solar energy and transferring it onto a receiving medium to be heated. The device comprises a multiplicity of blades (16), mutually spaced and tiered up to form a screen (10) with an external surface (18) for exposure to the sun radiation and an internal surface (20) for being arranged on the side of the receiving medium (12), the blades defining between them a multiplicity of air channels (22) extending from the external surface (18) to the internal surface (20), closing means being provided for immobilizing the air contained in the channels, the blades being transparent or translucent, with low capacity for absorbing the sun radiation and low thermal conductivity, being made from a lap of thin material, and having an outline with an end part bordering the internal surface of the screen.</p> |
