Abstract
An acoustic door for an equipment enclosure, such as a rack mount cabinet, also provides a low impedance air flow uniformly delivered across the cabinet opening. A pair of metal panels, with acoustic foam along the rear surfaces, extend angularly outward and toward one another to form an air inlet opening between the outer edges. A central column is positioned between the panels which, in a horizontal section, forms an aerodynamic dome which has a continuously curved sheet metal surface at the front and sides that also captures a core of acoustic foam that is exposed at the rear. A rigid vane is disposed at each lateral side and parallel to the central column to cause air to follow the column surface, deflecting air behind the column and effecting uniform delivery of air flow across the cabinet front opening at the rear opening of the door.
