Abstract
A fan for a cooling system of a motor vehicle has a closed impeller with a plurality of radial vanes, each of which is provided with an essentially radially oriented vane base. The radial vanes extend in a generally radial direction with respect to an axis of rotation of the impeller. An inner contour of the vanes is defined by leading edges of the vanes, and an outer contour of the vanes being defined by trailing edges of the vanes. The exterior diameter of the outer contour of the radial vanes and the interior diameter of the inner contour of the radial vanes decrease in a direction from the cover disk toward the impeller bottom.
