ABSTRACT:
The present invention provides a cooling fan system for a chassis configured to contain heat generating electrical components and to assume horizontal and vertical alternative operating orientations. The cooling fan system includes a support member securable within the chassis and having an air flow opening formed therein. Additionally, the cooling fan system includes a louver member hingedly attached to the support member to rotate between an open position wherein a substantial air flow is allowed through the air flow opening and a closed position wherein the louver member covers the air flow opening. The louver member may be made from plastic, however, other types of rigid materials that can withstanding the chassis' operating conditions could also be used, such as metal. The axis of rotation of the louver member is oriented with respect to the chassis to allow gravity to urge the louver member toward the closed position when the chassis is positioned in either the horizontal or vertical alternative operating orientations, to thereby prevent a back-flow of air in the chassis.
