Abstract:
1. A roofing panel incorporating a heat exchange assembly, said roofing panel including: an internal fluid passageway formed between a pair of spaced substantially parallel internal sheets for the passage therethrough of a fluid; respective external passageways formed between each said internal sheet and a respective external sheet spaced from and substantially parallel to a respective internal sheet, spacing ribs between said sheets and forming with said sheets a plurality of fluid conduits within said internal fluid passageway and a plurality of external conduits within said external passageways; said pair of internal sheets at the ends of said internal passageway extending beyond said external sheets at the ends of said external passageways thereby facilitating fusion welding to said internal sheets at the ends of said internal passageway, said panel being sealed at the sides thereof by said spacing ribs and being open at the ends thereof to provide access to said conduits which extend from one end of the panel to the other end thereof, and said internal passageway or said external passageways being adapted to receive or contain a gas for effecting heat exchange with a fluid in the other of said internal passageway or said external passageways; and at least one manifold having a fluid communication means for the inflow or outflow of a fluid to or from said fluid conduits, and a gas communication means for the inflow or outflow of a gas to or from the external conduits.
