Summary of the invention
Be operated under the optically focused pattern in order to overcome existing solar-energy photo-voltaic cell, because of the photovoltaic cell group temperature rise that photovoltaic cell group heat radiation difficulty causes too high, and cause the deficiency of whole generating system works reliability decrease, the utility model proposes new technical scheme: adopt semi-conductor thermo-electric generation module, the temperature that produces when utilizing the work of photovoltaic cell group, and the temperature difference between the lower temperature of environment, secondary electricity generation.Temperature rise when having solved the work of photovoltaic cell group effectively.The electric energy of the electric energy of semi-conductor thermo-electric generation module output and the output of photovoltaic cell group merges, and has improved the photoelectric conversion efficiency of whole system again greatly.
The technical scheme that its technical problem that solves the utility model adopts is: the solar-energy photo-voltaic cell group is fixed on the metal heat accumulation plate.In order to reduce the thermal resistance of solar-energy photo-voltaic cell group to metal heat accumulation plate transmission heat, it is necessary keeping tight contact between the two.The another side of metal heat accumulation plate is the hot side of temperature-difference power generation module group, based on same reason, also is closely to contact between them.The cold junction of temperature-difference power generation module group closely contacts with air-cooled radiator.Fill with heat-insulating material at the periphery of temperature-difference power generation module group and the space between module and the module in order to prevent hot short circuit.For the huyashi-chuuka (cold chinese-style noodles) of the generating efficiency temperature-difference power generation module group that improves the temperature-difference power generation module group can be used water-cooled (or oil cooling).This moment, the huyashi-chuuka (cold chinese-style noodles) and the heat exchanger of temperature-difference power generation module group combined, and heat exchanger is connected with radiator by heat radiation working medium pipeline.This moment, the heat-carrying working medium of liquid-cooling system was light water or oil or anti-icing fluid.The areas to the south, the Changjiang river that adopts water-cooled to be adapted at China uses, and should use oil cooling or anti-icing fluid at extremely frigid zones, to guarantee the safe handling of equipment.The plane mirror that is complementary with solar-energy photo-voltaic cell group area is fixed on four orientation up and down of solar-energy photo-voltaic cell group its setting angle and guarantees that incident sunray can reflex on the solar-energy photo-voltaic cell group and get final product by connector.The output electrode of solar-energy photo-voltaic cell group and the output electrode of semi-conductor thermo-electric generation module are connected with total output electrode by the anti-return Schottky diode respectively.
The beneficial effects of the utility model are, under the effect of planar concentrating mirror, solar-energy photo-voltaic cell can be worked being four times under the output of sunlight direct projection pattern electric energy.The solar-energy photo-voltaic cell group is digested by semi-conductor thermo-electric generation module because of the additional high temperature that the optically focused effect produces, and is converted into the electric energy stack output of electric energy and solar-energy photo-voltaic cell output, has improved the photoelectric conversion efficiency of whole system significantly.Under specific need for electricity, reduced the investment cost of system.
