Abstract: Provided is a fan shroud assembly and, more specifically, a fan shroud assembly including a swirling airflow-preventing saw-teeth which is arranged along a predetermined inner circumferential surface of a ventilating part while maintaining a predetermined gap from an end portion of a blade of a fan or an end portion of a fan band of the fan and are formed in a saw-toothed shape, in which both a first area in which the swirling airflow-preventing saw-teeth are formed and a second area from which the swirling airflow-preventing saw-teeth are removed are formed, thereby generating a swirling airflow of ventilated air due to a reduction in pressure fluctuation and thus effectively reducing noise.
