A fan assembly includes a mounting bracket, a fan, and a baffle. The mounting bracket includes two side plates bounding an outlet, and each side plate defines a through hole. An inner side bounding the through hole defines an arc-shaped cutout, communicating with the through hole. The baffle includes two pins rotatably received in the through holes of the side plates. A protrusion protrudes out from each pin, and is engaged in the corresponding cutout. When the fan operates, the baffle is pushed to rotate to open the outlet, to allow air from the fan to flow out through the outlet. When the fan ceases operation, the baffle rotates back under force of gravity to a position to cover the outlet, where the protrusion resists against one end of the cutout such that further rotation is prevented, to prevent air intake into the mounting bracket through the outlet.

1. A fan assembly comprising: a mounting bracket comprising two side plates bounding an outlet, each side plate defining a through hole, an inner side bounding the through hole defining an arc-shaped cutout, communicating with the through hole;a fan mounted in the mounting bracket, between the side plates; anda baffle pivotably mounted to the side plates at the outlet, wherein the baffle comprises two pins pivotably received in the through holes of the side plates, correspondingly, a protrusion protrudes out from each pin to be engaged in the cutouts, wherein when the fan operates, the baffle is pushed by air from the fan to rotate to uncover the outlet, to allow the air from the fan to flow out of the mounting bracket through the outlet; when the fan ceases operation, the baffle rotates under force of gravity to a position to cover the outlet, where the protrusion resists against one end of the cutout such that further rotation is prevented, to prevent air intake into the mounting bracket through the outlet through the outlet. 2. The fan assembly of claim 1, wherein the baffle comprises a shaft and a blocking piece extending from a circumference of the shaft, the pins extend from opposite ends of the shaft, the blocking piece is configured to cover or open the outlet. 3. The fan assembly of claim 2, wherein two flanges are formed at the opposite ends of the shaft, the pins extend from the flanges along an axis of the shaft, correspondingly. 4. The fan assembly of claim 3, wherein the flanges abut against inner sidewalls of the side plates, each protrusion is connected to the corresponding flange. 5. The fan assembly of claim 1, wherein the mounting bracket further comprises a bottom plate, the side plates extend from opposite sides of the bottom plate, correspondingly, the fan is supported on the bottom plate, and sandwiched between the side plates, facing the baffle. 6. A fan assembly comprising: a mounting bracket comprising two side plates bounding an outlet, each side plate defining a plurality of through holes, an inner side bounding each of the through holes defining an arc-shaped cutout, communicating with the through hole;a fan mounted in the mounting bracket, between the side plates; anda plurality of baffles pivotably mounted to the side plates at the outlet via the plurality of through holes, wherein each of the baffles comprises two pins pivotably received in corresponding two of the through holes of the side plates, a protrusion protrudes out from each pin to be engaged in the corresponding cutout, wherein when the fan operates, the plurality of baffles is pushed by air from the fan to rotate to uncover the outlet, to allow the air from the fan to flow out of the mounting bracket through the outlet; and when the fan ceases operation, the baffle rotates under force of gravity to a position to cover the outlet, where each of the protrusions resists against one end of the cutout away such that further rotation is prevented, to prevent air intake into the mounting bracket through the outlet through the outlet. 7. The fan assembly of claim 6, wherein each baffle comprises a shaft and a blocking piece extending from a circumference of the shaft, the pins extend from opposite ends of the shaft, the blocking piece is configured to cover or open the outlet. 8. The fan assembly of claim 7, wherein a bottom of the blocking piece of one baffle overlaps the shaft of an adjacent baffle, to cover the outlet.
