Abstract

The invention relates to the technical field of thermoelectric power generation, in particular to a thermoelectric power generation device with high thermoelectric conversion efficiency. The invention discloses a thermoelectric power generation device with high thermoelectric conversion efficiency, which comprises a medium-temperature thermoelectric power generator heat source, a low-temperature thermoelectric power generator heat source, a combustor and valves for controlling an airflow passage. The valves comprise a first gas path valve enabling the medium-temperature thermoelectric generator heat source to be communicated with the combustor and a second gas path valve enabling the low-temperature thermoelectric generator heat source to be communicated with the the combustor. The medium-temperature thermoelectric generator heat source adopts a thermoelectric generator made of a medium-temperature thermoelectric sheet, the low-temperature thermoelectric generator heat source adopts a thermoelectric generator made of a low-temperature thermoelectric material, and the combustor is made of a low-heat-conductivity-coefficient material. When the fuel flow is large, the first gas path valve is opened, and the second gas path valve is closed; and when the fuel flow is small, the first gas path valve is closed, and the second gas path valve is opened. The thermoelectric conversion efficiency of an existing thermoelectric generator can be improved.
