Abstract

A heat exchanger for cooling exhaust gas of a motor vehicle with a closed flow guiding system for the exhaust gas has heat exchange elements which are arranged between a feeding device and a removing device for the exhaust gas and around which a cooling medium flows. Heat exchange elements are disk-shaped and are each joined together from two metal sheets. At least one turbulence insert 20 is arranged between the sheets and comprises projections which extend diagonally with respect to the flow direction and project upwards from a surface.
