Abstract
A ventilation system for a cabinet, such as a cabinet containing heat-producing components of a data processing system, those components being arranged stacked in the cabinet in tower fashion, has four identical fan units for drawing air over the components and discharging the air from the cabinet. The fan units are disposed at mid-height in the cabinet, and are divided into two pairs. The fan units in each pair have their respective air intake directions facing toward each other. The fan units of one pair are disposed directly one above the other, and the fan units of the other pair are disposed a distance apart, forming a horizontal air duct therebetween. Partitions are disposed in the cabinet for causing the fan units in the first pair to discharge air into the duct formed between the fan units of the other pair, the duct conducting the air to an exterior of the cabinet. The partitions cause the fan units of the other pair to discharge air in a direction out of the cabinet.
