Thermoelectric generator based on dynamic radiation refrigeration

Abstract

The invention provides a temperature difference generator based on dynamic radiation refrigeration, and belongs to the technical field of radiation refrigeration devices, the temperature difference generator comprises a heat conduction metal and heat dissipation frame, metal fins, a thermoelectric module, a heat insulation frame, a radiation refrigeration film and an optical structure window; the radiation refrigeration film of the thermoelectric generator forms a cold end, and the lower end of the generator is heated through the metal fins in an environment convection mode to form a hot end, so that temperature difference is formed; the thermoelectric module is formed according to the Seebeck effect, and the upper end of the thermoelectric module is directly connected with the radiation refrigeration film to serve as a low-temperature end; the lower end is used as a high-temperature end through the heat-conducting metal, the heat dissipation frame and the metal fins; therefore, temperature difference is formed at two ends of the thermoelectric module, carriers in the thermoelectric module are respectively accumulated to a high-temperature end and a low-temperature end under the driving of the temperature difference, potential difference is generated in a circuit of the thermoelectric module, and when an external circuit forms a closed loop, current is generated, and thermoelectric power generation is realized.
