Abstract:
An assembly (10) for coupling thermally a thermoelectric generator (TEG (12)) to an exhaust manifold of an internal combustion engine. The exhaust manifold forms a first heat exchanger (14) configured to couple thermally heat from exhaust gas (16) to an outer surface (22) of the first heat exchanger (14). The outer surface (22) is preferably formed of stainless steel. A first dielectric layer (24) is formed by firing a thick-film dielectric material onto the stainless steel of the first heat exchanger (14). A first conductor layer (26) is formed by firing a conductive thick-film onto the first dielectric layer (24). A first paste layer (32) of silver (Ag) based sintering paste is interposed between the first conductor layer (26) and a first contact (30) of the TEG (12). The first contact (30) is sintered to the first conductor layer (26) when the assembly (10) is suitably arranged and suitably heated.
Abstract:
An assembly (10) for coupling thermally a thermoelectric generator (TEG (12)) to an exhaust manifold of an internal combustion engine. The assembly (10) includes a first heat exchanger (14) configured to guide exhaust gas (16) of an internal combustion engine past an opening (23) defined by the first heat exchanger (14), and a heat sink (50) configured to couple thermally the TEG (12) to the exhaust gas (16) and fluidicly seal the opening (23). The assembly (10) is configured so the heat sink (50) is directly exposed to the exhaust gas (16) so that heat is efficiently transferred from the exhaust gas (16) to the TEG (12).
