ABSTRACT:
An outlet airflow direction control device includes a fan and a frame. The frame has an inlet and an outlet via which an amount of fluid flows into and out of the frame, and is internally provided at the outlet with a hub seat for supporting the fan thereon. A plurality of fluid control elements are radially provided between the frame and the hub seat to connect them to each other. Each of the fluid control elements is connected at an outer end, which forms a directional-guide section, to the frame, and at an inner end, which forms a connecting section, to the hub seat. The directional-guide section has an area larger than that of the connecting section, so that the fluid control elements are adapted to control a flow direction of the fluid flown out of the outlet of the frame.
