Technical field
The present invention relates to a kind of thermoelectric conversion device of solar photovoltaic generation system.
Background technology
What the most solar power system adopted is opto-electronic conversion or photo-thermal electricity translative mode.Opto-electronic conversion is based on the photon effect principle, and its generating capacity is limited.And traditional photo-thermal electricity conversion power generation system not only can't evenly absorb sunlight, and needs to lean on the rotation of high temperature refrigerant driving generator to produce electric energy.Because introduced mechanical transmission component, so the maintenance of equipment and operation cost are higher, reliability is lower.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of thermoelectric conversion device of solar photovoltaic generation system, maintenance and operation cost are low, and reliability is high.
To achieve these goals, the technical solution used in the present invention is:
A kind of thermoelectric conversion device of solar photovoltaic generation system, comprise condenser system 1, the bottom surface of condenser system 1 is connected with heat collector 2 end faces, the bottom surface of heat collector 2 is connected with thermo-electric generation element 3 end faces, the bottom surface installation of heat radiator 4 of thermo-electric generation element 3, the radiating fin of radiator 4 is exposed in external environment.
The set of lenses that described condenser system 1 adopts single lens or a plurality of lens to form.
Described heat collector 2 can adopt the metal material (as: copper etc.) of high thermoconductivity to be made into entity patterns, also can be in the inner extraordinary working medium (as: water etc.) of filling of heat collector 2, and the heat conduction ester is smeared at heat collector 2 and thermo-electric generation element 3 applying positions.。
Described thermo-electric generation element 3 hot junctions and cold junction contact-making surface are smeared the heat conduction ester, smear adiabatic coating in its two sides.
The heat conduction ester is smeared at described radiator 4 and thermo-electric generation element 3 applying positions, and the radiating fin of radiator 4 adopts the high metal material of thermal conductivity, and sprays pitch-dark or anodized.
The present invention adopts the condenser system of particular design evenly to absorb sunlight, and heat collector provides stable hot-side temperature, and the thermo-electric generation element utilizes the method for Seebeck effect generating.Condenser system with solar light focusing on heat collector, heat collector evenly is delivered to the hot junction of thermo-electric generation element by the outer wall of high conductivity fast with heat, heat collector itself has larger thermal capacity, can provide certain heat in the insufficient situation of sunlight, reduce on the one hand the thermal shock of sunlight strength change to the thermo-electric generation element, delayed on the other hand the outage that causes because sunlight is inadequate.The cold junction installation of heat radiator of thermo-electric generation element by the external environment heat convection, forms the temperature difference with the hot junction, thus generation current.In order to guarantee the cold and hot end temperature difference of thermo-electric generation element as far as possible, smeared adiabatic coating in its both sides, reduced due to cross-ventilation and the hot cold and hot end exchange heat that causes of conducting of sidewall.The present invention reforms traditional power generation mode, without moving-member, not limited by installation site and direction, and volume is little, lightweight, simple to operate.
