Abstract A solar panel assembly consisting essentially of a heat-collector fluid passage through which the air, for example, to be heated is passed for heating by convection and radiation. The panel comprises a ray-absorbing back or inner panel and a ray-passing diaphanous outer panel which is spaced forwardly thereof to provide the air passage through which the air to be heated is passed. The outer panel is so formed relative to the rear panel that the air passing through the passage is caused to travel in intimate contact with the ray-absorbing panel so that the absorbed heat will be effectively transferred to the passing air. This is accomplished by having the cooperating panels produce successive transverse slots in the direction of flow of the air stream which are constricted to offer resistance to the flow of the air stream to increase its velocity over the ray-absorbing rear panel with a minimum decrease in the pressure of the stream, much like a Venturi tube.
A solar-heating panel assembly comprising a ray-absorbing inner panel and a ray-passing outer panel spaced outwardly therefrom to provide a fluid passageway therebetween through which the fluid to be heated is passed, said panels being formed relatively to provide successive restricted slots and expansion pockets along the passageway in the direction of and transversely of the flow of the fluid to be heated, and inlet and outlet means for said passageway to produce and flow; said ray-passing panel being of corrugated diaphanous material with its corrugations extending transversely to provide alternating Venturi-like slots and expansion pockets transversely of the flow of fluid through the passageway, said inner panel being of black material and having ribs on its surface which extend longitudinally of the passageway and substantially at right angles to said corrugations of the ray-passing panel.
