ABSTRACT:
A computer system includes a housing that is divided into three compartments; two fan compartments, each containing a fan, and a third compartment containing heat generating electronic components. The air discharged from the fans flows through outlets in the fan compartments and into the third compartment to cool the electronic components. A single baffle is rotatably coupled between the two fan compartments using a vertically oriented hinge. When one of the fans fails, the air pressure from the working fan rotates the baffle until it covers the outlet of the fan compartment containing the failed fan. This enhances the flow of air from the working fan into the third compartment, and restricts the reverse flow of air through the dead fan compartment. When both fans are functioning, air pressure from both fans moves the baffle to a "midway" or "neutral" position, such that the air from both fans flows into the third compartment.
