Abstract

The present invention relates to an exhaust manifold (15) for an exhaust system (5) of a combustion engine (1), in particular of a motor vehicle, with an exhaust channel (16) for conducting exhaust gas, which comprises an inlet side (17) that can be connected to the combustion engine (1) and an outlet side (19) that can be connected to the exhaust system (5), and with at least one coolant channel (20) for conducting coolant, which is arranged on the outside of the exhaust channel (16) and can be connected to a cooling circuit (6).In order to reduce the thermal load on the exhaust manifold (15), at least one thermoelectric converter (22) can be provided, which on the one hand is coupled to the exhaust channel (16) and on the other hand to the coolant channel (20) in a heat-transferring manner.
