The invention discloses a micro heat pipe-based solar cavity type thermoelectric power generation device. A groove type paraboloid condenser is rotationally connected with a rotating main shaft; the groove type paraboloid condenser rotates in a vertical plane by taking the rotating main shaft as a center; the two ends of a core power generation device are connected with the two sides of the groovetype paraboloid condenser through connecting supports; the core power generation device is located in the paraboloid of the groove type paraboloid condenser; an irradiation sensor is installed on theside face of the groove type paraboloid condenser; a controller is in control connection with the irradiation sensor and the rotating main shaft; and micro heat pipes, a heat collection water tank and a flow meter in the core power generation device are sequentially communicated with one another through a water conveying copper pipe to realize circulation. According to the micro heat pipe-based solar cavity type thermoelectric power generation device of the invention, a selective heat absorption coating is used for rapidly transferring the heat of a photovoltaic cell to a thermoelectric cell,so that the temperature of a photovoltaic panel is reduced, therefore, photovoltaic power generation efficiency is improved, and the service life of the photovoltaic cell is prolonged; meanwhile, waste heat is utilized for power generation, the power generation efficiency of the system is improved, and solar full-spectrum utilization is achieved.
Description
technical field [0001] The invention relates to a solar cavity type thermoelectric power generation device based on a micro heat pipe, and belongs to the field of solar thermoelectric power generation. Background technique [0002] The energy stored on the earth is the basis for the survival of human society and the development of social technology. In the development of human society, the demand for energy is increasing. Today, the world's energy consumption structure is still dominated by fossil energy such as oil and natural gas. As a renewable and clean energy source, solar energy contains huge energy, and is generally considered to be an ideal new energy source. The total power radiated from the sun to space is as high as 3.8×10^23kW, of which 1.8×10^14kW will reach the earth, and about 60% of the energy will be applied to the earth, that is, about 1.1×10^14kW of energy will reach the Earth's surface. Assuming that among the 1.1×10^14kW of energy, only 0.1% of the en...
