摘要

Device for cooling a, a flow channel (4) surrounding flow duct wall (1) with at least one, in a, through the flow channel (4) which flows through the flow medium flow vortices induced rib element (2, 3), which at the, the flow channel (4) facing side of the flow duct wall (4) is attached and the shape and size of under considerations of a specific heat transfer coefficient, as well as of a specific, with the flow of the rib element (2, 3) with the flow medium are selected in this connected pressure loss,characterized in that the rib element (2, 3) largely while retaining its original shape and / or size of its, the flow channel (4) increases the surface facing has contours,that the rib element (2, 3) has a square or rectangular cross section and of the vehicle, as a contour which increases its surface a groove (5) on its, the flow channel (4) side facing andthat the rib element (2, 3) a rib width w, and a rib height e and the groove (5) a groove depth d and a groove width b..
