Patent ID: 11725669

Abstract:
In the application disclosed are a wind shroud, which is used in a fan with a movable impeller, and a fan with the same. The wind shroud is integrally formed and comprises a body configured to be internally hollowed in an axial direction of the body for receiving the movable impeller. The body comprises an air inlet end and an air outlet end, and the air inlet end has an inner sidewall and an outer sidewall spaced apart from each other to form a silencing cavity for buffering the vibration generated when the movable impeller is rotated, so as to reduce the noise of the fan. In a direction from the air inlet end to the air outlet end, a distance between the inner sidewall of the air inlet end and the outer sidewall of the air inlet end first gradually increases, and then gradually decreases. In the above manner, where the wind shroud of the present application is applied to a fan, the noise problem of the fan can be effectively addressed.
