<p>Radiation energy absorber comprises a number of tub made from a material with a high thermal conductivity such as steel, copper, aluminium or aluminium alloy, associated with heat-exchanging surfaces. Pref. in a solar energy absorber, the heat-absorption surfaces are arranged longitudinally and mounted in pairs on an inclined support. The surfaces of each pair form an angle 30 degrees between them to make a number of triangular conduits. The external face of each pair of conduits is connected by tubes so that a passage is formed for the continuous flow of a heat-transfer liq. which is esp. water. The appts. is mounted in a frame which supports a double pane of glass while the intermediate plate is provided with a top reflecting layer. The insulating zone is carried by the base plate. Pref. all the interstices in the appts. are filled with foam so as to obtain the max. thermal insulation. The appts. approx. doubles the yield of existing heat absorbers and can be connected to any heating circuit or appts.</p> |
