Abstract
A device for exhaust gas heat utilization in internal combustion engines of motor vehicles includes an exhaust gas line which in sections includes a first exhaust gas flow duct and a second exhaust gas flow duct connected in parallel. A valve flap is movable between a closed position and an open position, which can selectively close or at least partly clear a flow cross-section of the first or second exhaust gas flow duct. At least one thermoelectric generator module is thermally coupled with the second exhaust gas flow duct and with a cooling circuit. The device also includes an expansion material actuator for temperature-dependent actuation of the valve flap.
