Abstract

An exhaust gas heat exchanger may include a tube bundle and a housing through which a coolant is flowable. The tube bundle may include a plurality of exhaust gas-conducting tubes held in a first tube base and a second tube base. The housing may enclose the tube bundle and may have face ends delimited by the first tube base and the second tube base. The housing may include a coolant inlet arranged in a region of the second tube base and a coolant outlet arranged in a region of the first tube base such that the coolant flows in counter flow relative to the exhaust gas. A plurality of coolant bypass passages may be arranged between the tube bundle and the housing. At least a subset of the plurality of coolant bypass passages may be at least partly blocked by an inlay structured and arranged to steer a coolant flow.
