Abstract
Abstract The invention relates to a solar energy collector of the type comprising a pick-up receiving the solar radiation and converting at least a part of this radiation into heat, and heat-exchange means bringing a heat-exchange fluid into thermal contact with the pick-up and evacuating this fluid towards a user station, said pick-up comprising an assembly of juxtaposed plates which are substantially parallel to one another and form a layer, wherein the distance between two adjacent plates is chosen so as to constitute a well of heat in which the solar radiation is subjected to at least two reflections, at least one of the opposite faces of this well of heat is selectively absorbent for the infrared part of the solar radiation, the two faces of this well are substantially reflecting for the rest of the solar spectrum, and the layer of plates is disposed between a front transparent wall receiving the solar radiation and a rear wall, these walls being substantially parallel to said layer and defining therebetween an enclosure in which a heat-exchange fluid circulates. The invention also concerns an installation employing this collector.
