Abstract:
A cooling fan module (10) for a vehicle is provided, including a frame (12) and a fan (18). The frame (12) includes an edge (16) which defines an opening (14) of a substantially circular shape through the frame (12) which allows the passage of a flow of air along the direction of an axis central (z) of the opening (14). The fan (18) includes a plurality of blades (20), the fan (18) being arranged to rotate around the central axis (z) to convey the flow of air through the opening (14). The edge (16) includes at least a first cylindrical wall (22) and a second cylindrical wall (24) coaxial with the central axis (z) of the opening (14). The second cylindrical wall (24) protrudes beyond the first cylindrical wall (22) in the direction of the central axis (z). The first cylindrical wall (22) is arranged at a first radial distance from the central axis (z), and the second cylindrical wall (24) is arranged at a second radial distance from the central axis (z), greater than the first radial distance.
