Embodiment Construction
[0031] Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail:
[0032] refer to figure 1, a cycle phase change cavity rotary thermoelectric conversion device, including a thermoelectric conversion unit 1, a central pillar 2 and a concentrating surface 3, the concentrating surface 3 adopts the shape of a rotating paraboloid, which can converge the incident sunlight to its focal point In a very small range, the size of the thermoelectric conversion unit 1 is significantly reduced; one end of the central pillar 2 is fixed on the concentrating surface 3, and the other end is fixed on the concentrating surface 3 through a flange connection. Focus position: the thermoelectric conversion unit 1 absorbs the solar energy reflected by the concentrating surface 3 and converts it into heat energy, and then converts it into mechanical energy and electrical energy output to realize thermoelectric conversion characteristi...

The circulating phase change cavity rotary thermoelectric conversion device comprises a light condensation surface, and a thermoelectric conversion unit fixed in a focal point position of the light condensation surface through a center support column; the thermoelectric conversion unit comprises a heating cavity, an impeller cavity, a liquid storage cavity, a condensation cavity,a support frame and a generator; the generator is fixed at the bottom of the heating cavity through the support frame; the impeller cavity is fixed at the top of the heating cavity, and a center axisthereof is overlapped with center axes of the heating cavity and the generator; the liquid storage cavity is fixed at the top of the impeller cavity; the condensation cavity is fixed at the top of the liquid storage cavity; a liquid storage cavity intake pipe and a liquid storage cavity liquid drainage pipe are connected between the heating cavity and the liquid storage cavity; an impeller cavityexhaust pipe is connected between the condensation cavity and the impeller cavity; and a liquid storage cavity liquid inlet pipe and a liquid storage cavity exhaust pipe are connected between the condensation cavity and the liquid storage cavity. The circulating phase change cavity rotary thermoelectric conversion device is simple and compact in structure and low in mass, and can be used for a light-condensed solar thermal power generation system.
Description
technical field [0001] The invention belongs to the technical field of mechanical devices, and in particular relates to a circular phase change cavity rotary thermoelectric conversion device, which can be used in a concentrating solar thermal power generation system. Background technique [0002] Due to the depletion of traditional non-renewable resources and the increasingly serious environmental pollution caused by the development and utilization of conventional energy, the development of clean and environmentally friendly renewable energy such as solar energy, geothermal energy, wind energy, and biomass energy has become the most urgent need for mankind. Among them, solar energy has great development value and broad application prospects because of its abundant resources, wide distribution, and low cost. [0003] Solar power generation mainly includes solar photovoltaic power generation and solar thermal power generation. Compared with photovoltaic power generation, the p...
