Heat exchanger for internal combustion engines

A heat exchanger for an internal combustion engine, comprising

• a first, elongated flow channel for a passage of exhaust gas from the internal combustion engine,
• a second flow channel arranged adjacent to the first flow channel for the passage of the exhaust gas,
• a line separate from the first flow channel for the passage of a coolant, wherein heat energy may be exchanged between the exhaust gas in the first flow channel and the coolant in the line, and wherein heat energy may not be exchanged between the exhaust gas in the second flow channel and the coolant in the line, and
• a valve channel with an adjustable valve element, wherein a distribution of the exhaust gases between the first flow channel and the second flow channel may be adjusted by adjustment of the valve element, wherein the valve channel has a recess such that the valve element contacts the recess essentially planely in at least one end position, stationary
• wherein the valve element has a pivotable valve flap and a stationary angled baffle plate, each of the valve flap and the angled baffle plate having a first end and an opposing second end, the first end of each of the valve flap and the angled baffle plate respectively connected to a common shaft,
• wherein an angled surface of the angled baffle plate, provided at the second end of the angled baffle plate, contacts and remains stationary against a distal end face of the second flow channel, and
• wherein the pivotable valve flap pivots to contact the recess in the at least one end position.
