Abstract
A cabinet having a pair of vertically stacked chassis separated by a central, vertically extending region. A pair of laterally spaced, vertically extending panels is disposed in the central region, the panels forming: a pair of outer compartments for receiving air exiting a corresponding one of the pair of laterally spaced vertically stacked chassis; and an inner compartment for receiving air exiting the pair of vertically stacked chassis. The panels have therein an array of openings in a lower portion thereof for passing portions of air in the outer compartments into the inner compartment. An upper portion of the panels inhibits portions of air in the outer compartments from passing into the inner compartment. The openings extend in rows horizontally across the panel. The number of opening in lower ones of the rows is greater than the number of opening in upper ones of the rows.
