Patent attributes
An air distribution arrangement is adapted to be arranged in a cabinet for housing rack-mounted equipment that generates heat in use. The arrangement can be part of the cabinet when constructed or it can be an add-on feature. The arrangement includes plenum structure comprising side walls and a top wall that cooperates with the front door of the cabinet and the faces of the rack-mounted equipment to define a plenum. An air box in the cabinet draws ambient air from adjacent the floor into the plenum at a rate of at least 850 cfm. The ambient air is cooler than the air in the cabinet. The faces of the rack-mounted equipment have openings for receiving the ambient air to cool the interiors thereof. After cooling the rack-mounted equipment the air can be exhausted back to the ambient. The side walls and the top wall of the arrangement are adjustable to permit adjustment of the depth of the plenum. Pressure in the plenum can be relieved by slots in the plenum structure.
