Research on the novel high-intensity thermoelectric generator and its application on HEV

Abstract

The thermoelectric generator used for recovered the waste heat of vehicle engine exhaust-gas, is a conversion device between the waste heat flow field and the change electric field, and the temperature field is the coupling field between them. One of the methods to increase the conversion efficiency of this type generator is to strengthen the conversion intensity among above fields. In this paper, a new internal-axial-netted thermoelectric generator is presented, which uses the 'stereo-electrodes' to touch and convect with the heat gas flow directly; uses the compensating wire to link separated cold source to make a great temperature difference. Though it uses the existing thermoelectric materials, the out-power density can be increased. The hybrid electric vehicle (HEV) equipped with engine and generator is a transitional type from the internal-combustion engine vehicle to electric, but a self-existent one. In this paper, the application scheme and key technologies of above high-intensity thermoelectric generator (HTG) as the main to supply electric power in HEV are also discussed.
