Abstract
A fan cover to divert the airflow of a fan to minimize thermal blind sports in electronic equipment. The fan cover comprises a frame with a hallow body and a base configured to securely fit on the rear surface of the fan. The fan cover further has a bell mouth extending from the base to define a fluid flow path and may have a hub located centrally within the hollow body of the frame and one or more ribs extending from the frame to the peripheral surface of the hub. A plurality of flaps are mounted on the peripheral surface of the bell mouth, wherein one or more of the flaps may each be angularly displaced to divert airflow in a desired direction within the electronic equipment.
Claims21
A fan cover for a fan, the fan generating airflow to cool at least one electronic component within an electronic equipment housing, said fan cover comprising:
- a frame defined by a hollow body with a base, said base configured to securely fit on a rear surface of the fan;
- a bell mouth (214) extending from an operative edge of said base in an operative direction to define a fluid flow path, said bell mouth channeling the airflow of the fan towards the at least one electronic component;
- a hub operably supported by said operative edge of said base substantially centered within the hollow body of said frame;
- and
- at least one flap operatively mounted on the peripheral surface of said bell mouth, wherein said at least one flap is configured to be angularly displaceable to least two predefined angles to direct the airflow in a desired direction to substantially minimize the generation of thermal blind spots within the electronic equipment housing.
A method for diverting airflow associated with a fan in an electronic equipment, comprising:
- positioning a fan cover on the rear surface of the fan to establish a fluid connection with the rear surface of the fan;
- operating the fan to induce airflow through said fan cover;
- providing a displaceable flap on said fan cover;
- and
- angularly displacing at least one of said flap of said fan cover to one of two or more predefined angles based on pre-determined airflow requirements for directing output air towards specific electronic components to substantially minimize thermal blind spots in the electronic equipment.
