Thermoelectric power generation system

Abstract

This invention discloses a thermoelectric power generation system, comprising: a first chamber containing heat transfer oil; a heat collection device connected to the first chamber and used to heat the heat transfer oil; a second chamber containing water; and a thermoelectric power generation mechanism connecting the first and second chambers, which generates electricity using the temperature difference between the heat transfer oil and the water. This invention features a simple structure and low cost. Utilizing heat transfer oil for thermal storage allows for continuous power generation at night, avoiding the pollution problems of photovoltaic systems and the complexity of solar thermal systems. Simultaneously, the cold-side water source can be natural streams or gravity-fed water towers, while the heat-side can incorporate industrial waste heat or geothermal energy, achieving multi-source heat utilization and efficient power generation.

Claims
