Abstract:
1. In a self-supporting, heliothermal flat collector module for use as a roof shingle, including: a self-supporting sheet metal panel having two sides and adapted to be irradiated by sunlight on one side, said sheet metal panel being formed with two opposing, angled edges to interlock with another sheet metal panel on a roof, a register-shaped arrangement of capillary tubes, separated from one another at a distance for the flow of a fluid medium, said arrangement being positioned on, and adhered to, the side opposite the side of the sheet metal panel to be irradiated, and a thermally-insulating, insulation core that is also positioned on the opposite side of the sheet metal panel to be irradiated, the improvement wherein the surface of the insulation core is planar, the capillary tubes of the register-shaped arrangement are placed in contact with the planar surface of the insulation core, the insulation core is bonded to the sheet metal panel by means of a non-metallic, elastic adhesive layer, the capillary tubes are at least partially embedded into the adhesive layer between the sheet metal panel and the insulation core, and the sheet metal panel is made of a titanium zinc alloy and is pre-weathered on the heat-absorbing side.
