Abstract
A method and apparatus may be employed for maintaining cooling efficiency during air mover failure. An electrical enclosure may include a heat-generating thermal load, multiple air movers configured to remove heat from the thermal load, and a backward-airflow reducing device configured to reduce the amount of air that can be drawn backwards through one of the air movers if that air mover fails. The backward-airflow reducing device may be a valve configured to open while the air mover if functioning and to close when the air mover is not functioning.
