AIR-COOLED THERMOELECTRIC POWER GENERATION APPARATUS AND SOLAR THERMAL POWER GENERATION APPARATUS USING AIR-COOLED THERMOELECTRIC POWER GENERATION APPARATUS

摘要

The purpose of the present invention is to provide an air-cooled thermoelectric power generation apparatus and a solar thermal power generation apparatus using the air-cooled thermoelectric power generation apparatus.This solar thermal power generation apparatus is provided with a solar heat collecting apparatus that heats a heat medium by means of solar light irradiation, an air-cooled thermoelectric power generation apparatus, and a heat medium transfer pipe that transfers the heat medium thus heated. The air-cooled thermoelectric power generation apparatus has a housing that is provided with an air inlet for taking in air, and an air-cooled thermoelectric power generation unit that generates power using heat of the heat medium. The air-cooled thermoelectric power generation unit is provided with a thermoelectric power generation element that generates power by means of a temperature difference, and a heat sink that dissipates heat from the thermoelectric power generation element. A temperature of a discretionary surface of the thermoelectric power generation element is increased by means of the heated heat medium, and a temperature of a thermoelectric power generation element surface, which is different from the heated surface of the thermoelectric power generation element, is reduced to be lower than the temperature of the heated surface by means of the heat sink and the air taken in from the air inlet, thereby generating power by means of the thermoelectric power generation element.
