Abstract
A mirror collector having a generally parabolic surface terminating near the vertex in a circular or cylindrical curve, an evacuated cylindrical heat entrapment tube composed of a clear glass for energy admission and two pair of elongated heat collector tubes centrally located in the heat entrapment tube for passing an inner fluid to be heated. The two pair of heat collector tubes are constructed of copper with a selective absorption coating for receiving heat and positioned so that the mirror collector concentrates substantially all incoming energy upon the central heat collector tubes.
