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.
Claims3
An outlet airflow direction control device, comprising a fan and a frame;
- said frame having an inlet and an outlet, and being internally provided at said outlet with a hub seat;
- and a plurality of fluid control elements being provided between said frame and said hub seat to connect said hub seat to said frame;
- and
- said fan being supported on said hub seat of said frame;
- said fluid control elements being radially arranged at said outlet of said frame, and each of said fluid control elements being connected at an outer end, which forms a directional-guide section, to said frame, and at an inner end, which forms a connecting section, to said hub seat, and said directional-guide section having a uniform first axial length and said connecting section having a uniform second axial length, wherein the first axial length is greater than the second axial length;
- whereby when said fan is rotated to cause an amount of fluid to flow into and out of said frame via said inlet and said outlet, respectively, said fluid control elements are adapted to control a flow direction of said fluid flown out of said outlet of said frame.
