Thermoelectric Generator To Engine Exhaust Manifold Interface Using A Direct-Bond-Copper (DBC) Arrangement

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
An assembly for coupling thermally a thermoelectric generator (TEG) to an exhaust manifold includes a first heat-exchanger, a first dielectric-layer, a TEG, and a direct-bond-copper-arrangement (DBC). The first dielectric-layer overlies a portion of the outer surface of the first heat-exchanger. The first dielectric-layer is formed by firing a thick-film dielectric material onto the stainless steel of the first heat-exchanger. The TEG defines a first contact suitable to be coupled thermally and electrically to the first conductor-layer. The DBC is interposed between the first dielectric-layer and the first contact of the TEG. The DBC is formed by an adhesion-layer formed of high-adhesion-copper-thick-film in contact with the first dielectric-layer, a bond-layer formed of copper-thick-film that overlies and is in contact with the adhesion-layer opposite the first-dielectric-layer, and a copper-foil-layer that overlies and is in contact with the bond-layer opposite the adhesion-layer.
