Embodiment Construction
[0038] Below in conjunction with the accompanying drawings and specific embodiments, the present invention is described in further detail:
[0039] refer to figure 1 , a schematic diagram of the structure of a dish-shaped concentrating solar thermoelectric conversion system. The parabolic dish solar reflector is installed on the apparent sun tracking system, which can concentrate sunlight into a small range of its focal plane, thereby significantly reducing the size of the thermoelectric conversion device and improving its conversion efficiency. For a parabolic dish solar reflector with a diameter of 5m, this convergence range is less than 30cm; for a parabolic dish solar reflector with a diameter of 15m, this convergence range is about 50 to 75cm. At the converging point, the extremely high heat flux can heat the working gas in a very short time. If a thermoelectric conversion device is installed at the convergence point, the air pressure in the cavity can be rapidly genera...

The invention provides a cyclical through hole cavity rotating type thermoelectric converter, and aims to simplify the structure of a conventional thermoelectric converter and reduce the mass of the conventional thermoelectric converter. The cyclical through hole cavity rotating type thermoelectric converter comprises a heating cavity body, a vane wheel body, an upper supporting body, an electric generator and a lower supporting body, wherein the heating cavity body comprises a heating cavity cover and a heating plate which are mutually fixed, and a sealing cavity is formed; an exhaust hole is formed in a lateral wall of the heating cavity cover; the vane wheel body comprises vane wheels and a vane wheel shaft; upper air inlet holes and lower air inlet holes are formed in the vane wheel shaft; the vane wheels are mounted in the cavity of the heating cavity body; the dimension of the outline of each vane wheel is equal to that of the sealing cavity of the heating cavity body; the heating cavity body is connected with the electric generator through the upper supporting body; and the electric generator is connected with the lower supporting body. According to the cyclical through hole cavity rotating type thermoelectric converter disclosed by the invention, the vane wheels heat hot air in the cavity to drive the vane wheel shaft through the cyclical opening of the exhaust hole in the lateral wall of the heating cavity body and the air inlet holes in the vane wheel shaft, so that the thermoelectric conversion characteristic is realized; and the cyclical through hole cavity rotating type thermoelectric converter can be applied to a paraboloid disk-type spotlight solar system.
Description
technical field [0001] The invention belongs to the technical field of solar energy applications, and relates to a thermoelectric conversion device, in particular to a thermoelectric conversion device that drives an impeller to rotate through a heating cavity with periodic through holes, thereby driving a generator to generate electricity, and can be used for dish-shaped concentrating solar energy Thermoelectric conversion system. Background technique [0002] Clean, environmentally friendly, cheap and high-quality renewable energy is an urgent goal pursued by today's human society, and it has a wide range of application prospects in modern human life. China added more renewable energy capacity in 2013 than the rest of Europe and Asia Pacific combined, and REmap 2030 research shows that the share of renewable energy in China's power generation sector is estimated to increase from 20% today to 2030 40%. [0003] Compared with other solar energy application systems, the exis...
