Abstract

The invention provides a thermoelectric generation device for a vehicle. The device comprises a box arranged on an exhaust pipeline of the vehicle, multiple hollow pipes arranged in the box in parallel, and a thermoelectric device arranged on the pipes in a sleeved mode and of an annular structure, wherein the box is provided with an air inlet and an air outlet, tail gas from an engine flows into the air inlet and is exhausted from the air outlet, and the distribution direction of the pipes is vertical to the airflow direction in the box. The thermoelectric generation device is simple in structure, compact in size and high in heat utilization rate, the structure of the bottom of the vehicle is kept as much as possible, and waste heat of the tail gas of the vehicle can be converted into electricity more effectively.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a thermoelectric power generation device for a vehicle, in particular to a thermoelectric power generation device which utilizes waste heat of exhaust gas from an automobile engine to generate electricity. Background technique [0002] As a new type of new energy and renewable clean energy technology, thermoelectric conversion technology has received extensive attention in the world in recent years. It uses semiconductor materials to directly convert heat energy and electric energy, and has the characteristics of small system size, high reliability, no emission of pollutants, and effective use of low-density energy. [0003] Among many thermoelectric materials, skutterudite-based compounds, as a typical medium-high temperature thermoelectric material, have great application prospects in high-tech fields such as the recovery and utilization of industri...
