Title:
THERMAL SOLAR FLAT COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2012/093062
Kind Code:
A3
Abstract:
The invention relates to a thermal solar flat collector, consisting of a heat transfer medium conduction system which is sealed in a water-proof manner at the edges and provided with an inlet and an outlet and which has at least two glass panes, which face the sun and are arranged spaced apart from each other, comprising a heat insulation layer facing away from the sun and a collector bottom, wherein the collector bottom forms the lower wall of the heat transfer medium conduction system and the innermost of the glass panes facing the sun forms the upper wall of the heat transfer medium conduction system, wherein the collector bottom is designed in the form of black glass and the heat insulation layer facing away from the sun is designed in the form of foam glass having closed porosity, having thermal expansion coefficients that are adapted to each other.
