1. A fan shroud assembly comprising:
a fan comprising a hub configured to be coupled to a rotary shaft of a motor, and a plurality of blades provided on an outer peripheral surface of the hub; and
a fan shroud comprising a peripheral part configured to surround an outer periphery of the fan, a planar part configured to face a heat exchanger, a ventilation port formed in a central portion of the peripheral part and configured to allow an airflow, which is generated by the fan, to pass through the ventilation port to blow air, a hub part provided at a center of the ventilation port and configured to accommodate and support the motor provided on a shaft of the fan, and a plurality of fixing members connected to an inner peripheral edge of the peripheral part and an outer peripheral edge of the hub part and disposed radially around the hub part,
wherein when a plurality of spaces between the plurality of fixing members are a plurality of unit ventilation spaces, a noise reduction means is provided in at least one selected from the plurality of unit ventilation spaces to control a part of the airflow passing through the ventilation port,
wherein the noise reduction means is a baffle that blocks a part of an outer peripheral edge side of the plurality of unit ventilation spaces,
wherein the baffle is formed such that one end thereof is disposed in the plurality of unit ventilation spaces and connected to the inner peripheral edge of the peripheral part, and two opposite ends thereof are connected to the pair of fixing members that defines two opposite boundaries of each of the plurality of the unit ventilation spaces.
