ABSTRACT:
An autonomic solar heat collecting system is provided. The heart of the system is a solar panel including a flat outer surface adapted to be exposed to the direction of the radiation of the sun. A flat or formed inner sheet is provided which is closely spaced from the outer surface section. Preferably, a flat, transparent plate is provided, which is spaced from, which covers, and is disposed outwardly from, the flat outer section, thereby forming an air-tight compartment between itself and the flat outer surface. Joining the inner and outer surfaces to one another at the top and at the bottom provides a hollow, fluid-tight cavity. Because the inner and outer surfaces are closely spaced from each other, the fluid is in the form of a thin fluid membrane. Means are provided for allowing entrance of a fluid into the cavity and means are provided for removal of the fluid from the other cavity. To provide most efficient control and heat removal, the collector should be made of two copper sheets, the outer of which is flat, separated about 0.016 inches apart with an enclosed volume of fluid not exceeding about 2.3 cu.in./square foot of panel. Due to the small volume of fluid circulating through the solar panel, low power requirements are inherent to the system, and low voltage power is ample to activate the solar energy collecting system independent of any outside power source. Thus, an essential feature of the autonomic system is low wattage, low power pump means activated by a small predetermined temperature differential, and the means for providing power for the operation of the system is solar cells or wet or dry batteries.
