SOLAR HEAT COLLECTOR PROVIDED WITH A SELECTIVELY ABSORBING COATING OF SOLAR CALORIFIC ENERGY

摘要

at. Solar heat collector. /P P b. This collector is characterized in that it comprises a heat collector element made of aluminum and provided with a coating allowing the selective absorption of solar heat energy, at least on the surface intended to be exposed to the sun, the coating with selective absorption being obtained by forming an oxide coating on the heat collecting element and by treating the coated element thus obtained in a solution containing a salt of a metal, so as to cause the deposition of the metal on said coating oxide. /P P c. Application as a new source of energy.
