Abstract
Cooling systems employing adjacent fan cages having cage walls with interflow passages are disclosed. A cooling system includes cooling fans disposed in adjacent fan cages. Cage walls of the fan cages direct flows from the fans to the outlet ports of the fan cages which are in fluid communication with electrical components within an electronics-containing enclosure. By forming an interflow passage between the adjacent fan cages, upon occurrence of an inoperable fan, a portion of the flow from an adjacent operable fan can pass to the outlet port of the fan cage of the inoperable fan via the passage and provide better cooling of the components impacted by the inoperable fan. In this manner, thermal damage is avoided while minimizing fan noise associated with higher fan speeds.
