Abstract
A computer and a system and method of cooling the interior of the computer wherein at least two fans are disposed in the interior of the computer and are operated simultaneously. At least one horizontally extending louver is provided on each fan so that, if one of the fans fails, the flow of air through the other fan is blocked by its louver to prevent interference with the air flow through the other fan.
Claims10
A computer comprising:
- at least one chassis;
- a plurality of components disposed in the chassis;
- a plurality of fans disposed in the chassis;
- at least one horizontally extending shaft mounted for rotation relative to each fan;
- a louver having a longitudinal edge connected along the length of each shaft for rotation therewith between:
- a horizontal open position in response to the air pressure established by the fan in which the louver permits air flow through the fan to distribute air over at least one of the components, and
- a vertical closed position under the force of gravity when the fan is inoperable in which the louver blocks air flow through the fan;
- and
- at least one counterweight attached to an area of each shaft diametrically opposite the portion of the shaft to which the louver is attached for establishing a force that counteracts a portion of the gravitational force on each louver to reduce the amount of air pressure required to open the louver.

A cooling system for an electronic device having at least one chassis and a plurality of components disposed in the chassis, the cooling system comprising:
- a plurality of fans disposed in the chassis;
- at least one horizontally extending shaft mounted for rotation relative to each fan;
- a louver having a longitudinal edge connected along the length of each shaft for rotation therewith between:
- a horizontal open position in response to the air pressure established by the fan in which the louver permits air flow through the fan to distribute air over at least one of the components, and
- a vertical closed position under the force of gravity when the fan is inoperable in which the louver blocks air flow through the fan;
- and
- a counterweight attached to an area of each shaft diametrically opposite the portion of the shaft to which the louver is attached for establishing a force that counteracts at least a portion of the gravitational force on each louver to reduce the amount of air pressure required to open the louver.
