Abstract
The invention relates to a thermoelectric device, comprising a first circuit (1), called hot circuit, through which a first fluid can flow, and, a second circuit (2), called cold circuit, through which a second fluid can flow at a temperature lower than that of the first fluid, and elements (3p, 3n), called thermoelectric elements, that can be used to generate an electric current in the presence of a temperature gradient. According to the invention, it comprises fins (5f) in a heat exchange relationship with said hot circuit (1) and/or said cold circuit (2), the thermoelectric elements (3p, 3n) being in contact at least with said fins (5f), said fins having tracks (32) for conducting the current generated by said thermoelectric elements.
