SOLAR PLANT FOR CONVERSION OF SOLAR ENERGY (ALTERNATIVES), METHOD AND EQUIPMENT FOR MAKING REFLECTORS Russian patent published in 2008 - IPC F24J2/14 

FIELD: lighting.

SUBSTANCE: solar plant for conversion of solar energy using the first alternative consists of concave in the form a rim reflector with a parabolic cross section, pipe in the form of a half ring for passage of the heat carrier, located in the region of the focal line of the reflector and equipped with an axis of rotation. The axis diametrically passes through the bottom of the side face of the rim, and on the pipe, and there is a loop on the pipe for enveloping the axis of rotation. The second alternative of the solar plant is equipped with two semi-axes, a reflector in the form of coaxially located two concaved semi-rings, fastened with their side surfaces, and a pipe in the form of long half-loop with bow-shaped sides, located piece by piece opposite the concaved semi-ring. The semi-axes are diametrically fixed on the inner surfaces of the ends of the semi-rings. The reflector for the solar plant is made from pieces of thin walled pipes. A concaved rim with a parabolic cross section is made. The resulting rim is divided by a diametrical lateral cut into two parts with formation of dissymmetrical halves and straight arches with cut bottom sides. The straight arch is plastically deformed from the side of the bottom cut until it conforms to the lateral surfaces of half of the rim. The equipment for shaping the reflector is in the form of a split cylindrical mandrel with a parabolic turning on the lateral surface.

EFFECT: invention increases effectiveness of converted solar energy.
