Abstract
This cooling fan device for a vehicle comprises: a fan shroud which is shaped as a box accommodating a radiator and/or a condenser, and which has an opening in the front side in the travel direction of the vehicle and a fan coupling surface in the rear side in the travel direction; at least two cooling fans disposed in the fan coupling surface, the cooling fans having center axes vertically separated from each other by a predetermined distance; and a shield rib extending downward from the top of the fan coupling surface, protruding toward the radiator and/or the condenser, and having a top end and a bottom end, the shield rib being provided to the fan coupling surface between the adjacent cooling fans. The top end and/or the bottom end of the shield rib have a cutout section allowing air to pass between the adjacent cooling fans.
