The present invention relates to a fan shroud provided in a cooling module, and the objective of the present invention is to provide a fan shroud including a circumferential portion surrounding the outer circumference of a fan and a flat portion facing and coupled with a heat exchanger, wherein a noise reduction hole formed by connecting a first hole extending in the circumferential direction of the circumferential portion and a second hole extending toward the flat portion to penetrate the flat portion is formed in a proper position, thereby reducing BPF noise effectively while minimizing degradation in stiffness and durability of the fan shroud. 본 발명은 쿨링모듈에 구비되는 팬 쉬라우드에 관한 것으로, 본 발명의 목적은 팬의 외측 둘레를 둘러싸는 둘레부 및 열교환기와 대면 결합되는 평면부를 포함하는 팬 쉬라우드에 있어서, 둘레부의 원주방향을 따라 연장되는 제1홀 및 평면부를 향해 연장되어 평면부를 관통하는 제2홀이 연결되어 이루어지는 소음저감홀을 적절한 위치에 형성함으로써, 팬 쉬라우드의 강성 및 내구 저하를 최소화하면서 효과적으로 BPF 소음을 저감하는 팬 쉬라우드를 제공함에 있다.
