In this research, a thermoelectric power generation device which uses exhaust gas of vehicle engine as hot source and circulated cooling water as cold source is designed, this device outputs electric power under the thermoelectric effect power generation theory, i.e. the Seebeck Effect. The effect of design parameters of this device structure on thermoelectric performance is analyzed, and the influence of temperature and flow rate of intake gas on the output performance of TEG device is verified through experiments. The paper also uses simulation software to analyze temperature field and velocity pressure field when automobile exhaust gas flows through this device and proposes ways to improve the output performance and efficiency of TEG device.
