More Information
Summary:The present invention relates to a heat exchanger for exhaust gas cooling, in particular for motor vehicles. The heat exchanger includes a flow duct which is formed from heat exchange tubes being arranged in parallel to one another, and through which the exhaust gas to be cooled can flow and around which a liquid coolant can flow, and secondly includes a housing having a housing wall and tube bottoms. The housing wall and the tube bottoms delimit a flow chamber for the coolant. The heat exchange tubes being arranged so as to form a tube bundle are formed with straight sections and deflection zones, wherein the heat exchange tubes in at least two deflection zones sweep an angle of at least 90°.
