Hybrid solar concentrator comprising concentrating means, a photovoltaic device and a thermal device for producing electricity

摘要

A hybrid solar concentrator for electric power generation comprising one (6) or more concentrating lenses (56.57) with different forms (1.3,4,5,40,45,47,48,49,55) placed at various distances between themselves (46,49,52) with different focal lengths and converging the energy of photons onto a central device (11) (liquid, oily or gaseous) (12,41), comprising a heater of a fluid (liquid, oily or gaseous) (10,12) placed in a sealed central circuit and under pressure (9,58), which expands as a result of the heat obtained from the concentrating lenses, flowing into fluid conduit (13) pushing a rotor with unidirectional motion (30) comprising a rotating magnetic or spring pin (31,32) rotating in one direction and held in place (closed-circuit and under pressure), through more positioning balls (16). Said heated fluid flowing through unidirectional valves (28,29,34,35) towards a special sealed container (38) at solid state, liquid or gas, acting as cooler with filling valves (39,53). The cooled fluid shrinks and re-enters, through unidirectional valves (34,35), the central container (9), closing the fluid circuit and being heated up again to repeat the cycle of thrust of the rotor blades (30). The rotor is connected through the magnetic attraction of polarized magnets (22) to an underlying dynamo, rotating and generating electricity. The system further includes photovoltaic cells sensitive to both to the visible and invisible light (infrared, etc..) and to the heat (7) put under the main lens (6). The device uses both visible and invisible light (infrared, ultraviolet and gamma rays, X,etc..) with various concentration points (40,42.43,45,50).The advantage of the invention is a compact concentrator generating more energy at lower cost.
