US 4,301,965 A · Heat collector system

Abstract

The heat collector system comprises a heat collector connected to a heat p. The heat collector has an inlet conduit and contains a heat transmitting fluid and is effective to take radiation heat from the environment. The heat collector has a structural configuration effective to additionally absorb convection heat as a convector which causes a good heat transmission between the ambient air and the heat transmitting fluid. A rated and controlled cooling device is connected to the heat conduit of the heat collector. The cooling device is effective to supply fluid to the heat collector at a temperature below the temperature of the ambient air. Further features of the invention include a regulating device effective to regulate the difference in temperature between the temperature of the ambient air and the cooling temperature. The collector may be composed of two superimposed chambers including an upper chamber made of transparent material and having a heat conductive surface and a lower chamber having a structural configuration effective to absorb heat radiation.
