Abstract: The present invention relates to a fan shroud provided in a cooling module, and an object of the present invention is to provide a fan shroud having a peripheral part configured to surround an outer periphery of a fan, and a planar part coupled to face a heat exchanger, in which a noise-reducing hole is formed at an appropriate position and defined by connecting a first hole, which extends in a circumferential direction of the peripheral part, and a second hole, which extends toward the planar part and is formed through the planar part, thereby effectively reducing BPF noise while minimizing deterioration in rigidity and durability of the fan shroud.
