Abstract (en)

[origin: DE102004045923A1] Flow channel for a heat exchanger containing a medium flowing in a flow direction (P) comprises two opposite-lying parallel heat exchanger surfaces (F1) provided with a structure formed by structural elements (13, 13') that protrude into the flow channel perpendicularly to the flow direction. At least two rows (17-20) with structural elements on opposite-lying heat exchanger surfaces overlap each other. An independent claim is also included for a heat exchanger, especially an exhaust gas cooling device for a motor vehicle. Preferred Features: At least one structural element is elongated, especially rectangular, with a linear longitudinal axis.
