The structure of the temperature difference power generation device is optimized and improved, power generation efficiency is improved, and the aim of improving the energy utilization rate is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile energy saving and emission reduction, and in particular relates to a thermoelectric power generation device and a vehicle exhaust waste heat thermoelectric power generation system. Background technique [0002] Resource scarcity and energy shortage are issues of common concern all over the world, and they are also technical bottlenecks restricting the rapid development of the traditional automobile industry powered by internal combustion engines. The utilization rate of limited vehicle fuel (gasoline and diesel) is also very low, and about two-thirds of the energy is dissipated into the air in the form of exhaust heat and mechanical loss. The purpose of the internal combustion engine does not match, and it is urgent to improve and improve the traditional internal combustion engine working process and emission process, and invent new energy-saving and emission-reducing mechanisms.
