Abstract

The present invention relates to thermoelectric power generation devices. The thermoelectric power generation device includes: a heat-absorbing surface configured to absorb heat from an internal combustion engine; a heat-generating surface bonded to the heat-absorbing surface through a semiconductor and configured to discharge heat to the outside; and a conduction conversion member inserted in the Between heat-absorbing surfaces and the internal combustion engine. The conduction conversion member is configured to allow heat to be conducted from the internal combustion engine to the heat absorbing surface when the temperature of the internal combustion engine is equal to or greater than a certain value.

Description

technical field [0001] The present invention relates to a thermoelectric power generation device, and more particularly, to a thermoelectric power generation device capable of using a phase change material / material that changes phase at a specific temperature only when the temperature of the internal combustion engine is above a specific value , to generate electricity by absorbing heat from an internal combustion engine. Background technique [0002] Thermoelectric power generation is power generation using the Seebeck effect in which an electromotive force is generated when a temperature difference is given across a material. Since a thermoelectric generator utilizing the Seebeck effect contains no dynamic parts and directly converts heat into electricity within the material without separately requiring fuel, it has high stability and emits no environmental pollutants. Meanwhile, in order to recover energy that is discharged as heat during operation of the internal combus...
