| Abstract: | According to energy utilization styles of vehicle exhaust gas,this paper presents a novel internal-axial-netted thermoelectric conversion system.In this system,thermocouples can directly experience heat transfer with heat gas flow inside exhaust pipe.This system can also increase the difference of temperature and intensify the heat flux density and electric current density,which can effectively increase the power density of thermoelectric generator with existing thermoelectric materials. |
