A COOLING SYSTEM AND AN AXIAL FAN FOR A COOLING SYSTEM

摘要

A cooling system comprises a circumferential edge (2) forming an aperture (3) and an axial fan (4) arranged at least partly within the aperture. The axial fan comprises a hub (5) being adapted for rotation about an axis (6) and carrying a plurality of blades (7). Each blade extends in a radial direction between a root end (8) and a tip end (9), where the root end is joined with the hub. The system further comprises brushes (10) extending from the tip end towards the circumferential edge, where the brushes at a first end are attached to at least one of the blades at a point of attachment at a distance from the tip end. The brushes overlap the blade from the attachment point to the tip end along the length of the brushes at a pressure side or suction side of the blade.
