Title:

THERMOELECTRIC POWER GENERATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/047563

Kind Code:

A1

Abstract:

A thermoelectric power generation device is provided with: a duct (7) through the inside of which a first fluid flows; a first power generation module (1) and a second power generation module (2) respectively making contact with outer surfaces of the duct facing each other and each internally provided with a thermoelectric power generation element; a first outer plate (3) and a second outer plate (4) making contact with outer surfaces of the respective power generation modules on the side opposite to the duct and welded to each other at both ends thereof; and outside fins (5, 6) respectively provided on outer surfaces of the first and second outer plates on the side opposite to the respective power generation modules and making contact with a second fluid flowing thereover, said second fluid having a higher temperature than the first fluid. Portions between the respective power generation modules and the duct and portions between the respective power generation modules and the first and second outer plates are mutually pressured and contacted. The duct is formed of a material having a larger thermal expansion coefficient than the first and second outer plates. Two power generation modules are not necessarily required. At least one power generation module (1 or 2) may be provided.
