Ventilation system for cabinets with electronic functional units which produce considerable heat
First Claim
1. A ventilation system for use in a cabinet having doors equipped with louvers and containing a plurality of functional units stacked in tower fashion one above another, said functional units producing heat, said ventilation system comprising:
- four identical fan units, each fan unit having a housing with a top and a bottom and open longitudinal sides with at least one fan disposed in said housing, each said fan having an axial air intake and a radial air discharge and an axis of rotation disposed perpendicularly relative to said bottom and top of said housing;
said four fan units being disposed in said cabinet at a mid-height of said cabinet and being divided into two pairs of fan units, the fan units in each pair being oriented with the respective axial intakes of the respective fans being oriented directly toward each other, the fan units in a first of said pairs being disposed closely above each other, and the fan units of a second of said pairs being spaced apart and forming a horizontal air duct therebetween for directing air out of said cabinet; and
a plurality of partitions mounted in said cabinet respectively adjacent said four fan units and causing said fan units in said first pair to discharge air into said horizontal air duct and causing said fan units in said second pair to discharge air out of said cabinet.

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.
