Abstract

The invention relates to a fan, particularly for cooling an internal combustion engine of a vehicle, having an attachment unit, an electric drive motor, and a fan wheel rotating about the fan axis, wherein the attachment unit has a frame, from which bars protrude that cross through an air opening, said bars carrying an attachment element serving to attach the drive motor. The invention proposes that each of the bars (6) have a cross-sectional contour, wherein at least one cross bar (18) extending laterally in the direction of the fan axis (9) is configured between end regions (14, 15) of the bar (6) extending in the direction of the fan axis (9), defining a bar width (b).
