Outlet airflow direction control unit

摘要

An outlet airflow direction control unit mainly includes a frame and a fan mounted in the 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 predetermined positions with a plurality of radially projected fluid control elements. When the fan is rotated to cause an amount of fluid to flow through the outlet of the frame, the fluid control elements provided in the frame are adapted to control a flow direction of the fluid flown out of the outlet.
