Title
(EN) THERMOELECTRIC CONVERSION ELEMENT
(FR) ELEMENT DE CONVERSION THERMOELECTRIQUE
Abstract
(EN)
A high-performance thermoelectric conversion element using an Si-group thermoelectric conversion material, and an thermoelectric conversion element capable of providing a high-output power by improving a power generating efficiency, wherein the thermal expansion coefficient of an electrode material is set to up to 10 ppm/K in order to provide a good electrode joining between a p-type thermoelectric conversion material and a n-type thermoelectric conversion material consisting of an Si-group thermoelectric conversion material to thereby ease thermal stress and prevent cracking and breaking at a joining portion, and, in joining, a brazing filler material selected according to a working temperature range is interposed to thereby provide good joining characteristics, reduce an output loss, and improve a heat resistance and a heat-cycle resistance.

L'invention concerne un élément de conversion thermoélectrique, très performant, mettant en oeuvre un matériau de conversion thermoélectrique du groupe Si, et elle concerne notamment un élément de conversion thermoélectrique capable de fournir une puissance de sortie élevée, par amélioration de l'efficacité de production de puissance, cet élément étant caractérisé en ce que le coefficient d'expansion thermique d'un matériau d'électrode est réglé pour atteindre jusqu'à 10 ppm/k, de manière à constituer un bon assemblage d'électrode entre un matériau de conversion thermoélectrique de type P et un matériau de conversion thermoélectrique de type N consistant en un matériau de conversion thermoélectrique du groupe Si, afin d'alléger ainsi la contrainte thermique et empêcher le craquement et la rupture au niveau d'une portion d'assemblage, et en ce que, lors de l'assemblage, un matériau de charge de brasage, choisi en fonction d'une gamme de températures de travail, est interposé qui offre de bonnes caractéristiques d'assemblage, réduit la perte de sortie et améliore la résistance thermique et la résistance de cycle thermique.
