Disclosed is a system for assisting in preventing over heating of the internal electrical components of a computer in the event of a failure of one of the adjacent fans of an array of fans employed to circulate cooling air over the components. The fans include openings through which air is forced from their inlet sides to their outlet sides. The system includes a vent for each fan arranged adjacent to and aligned with the fan opening at its outlet side. The vents are open and closed by vanes, having hinged slats construction to allow them to fall downwardly by their own weight or additional assistance. The vanes are kept open by the airflow created by the fans. Upon the failure of a fan, the absence of airflow through the opening thereof allows the slats of the vane to drop to close off the fan opening and prevent airflow into the fan opening from its outlet side.

[ I claim:] [1.] In a computer comprising a number of heat generating electrical components that require cooling,at least two cooling fans arranged adjacent to each other,a facility constructed to support said fans,said fans each comprising an inlet side and an outlet side,each said fan comprising a fan opening,a vent facility for each said fan,a facility for each said vent facility for supporting and locating said vent facility adjacent to an associated fan,each said vent facility comprising an opening aligned with and at least substantially as large in area as the area of an associated fan opening,a vane facility for each said vent facility,each said vane facility comprising a series of elongated substantially equal length slats having relatively narrow planar uniform widths,said slats having fan air flow open and fan airflow closed positions,said slats of each vane facility having a side by side parallel adjacent relationship to each other and arranged to at least substantially cover the entire area of an associated opening when in said closed position, andeach said vent facility comprising a facility constructed to pivotally support its associated slats from common opposed sides of said vent facility in a manner that airflow created by said associated fan causes movement of said associated slats in a direction relative to said associated fan to allow airflow by said associated fan through said opening of said associated fan relative to said components and in the absence of airflow from said associated fan to allow said associated slats to close off said associated fan opening preventing airflow through said associated fan opening.
