PURPOSE: A cooling fan assembly for a vehicle is provided to minimize an interference noise in the conventional double fan by inverting the inclination of the front fan blades and the bending angle of the rear fan blades. CONSTITUTION: A cooling fan assembly for a vehicle includes a drive motor, a shroud, and front and rear fans. The drive motor(100) includes a rotation shaft(110). The shroud(200) has a ventilation hole(210) in the center, and a motor fixing part(230) which is extended by stators(220) in the centrifugal direction on the inner circumference of the ventilation hole in order to fix and support the drive motor. The front and rear fans(300,400) include hubs(310,410) combined with the rotation shaft and radial blades(320,420) arranged on the hubs. The blade tip of the front fan has a frontward bending angle and the blade tip of the rear fan has a rearward bending angle. |
