Abstract:
1. A thermoelectric device, comprising a first circuit, called hot circuit, through which a first fluid can flow, and a second circuit, called cold circuit, through which a second fluid can flow at a temperature lower than that of the first fluid, and elements, called thermoelectric elements, that can be used to generate an electric current in the presence of a temperature gradient, characterized in that it comprises fins in a heat exchange relationship with said hot circuit and/or said cold circuit, the thermoelectric elements being in contact at least with said fins, said fins having tracks for conducting the current generated by said thermoelectric elements; in which the fins have a core made of metal material, provided with two faces, coated with a thermally conductive and electrically insulating substrate on at least one of the faces of the core, said tracks being provided on a face of the substrate opposite the face of the substrate in contact with the core; and in which the fins are grouped in pairs, a compressible material being provided between the fins of one and the same pair, said fins having tracks only on their face opposite that which is in contact with the compressible material.
