Abstract:
1. An acoustic door for an equipment enclosure housing electronic equipment which accommodates an air flow for cooling electronic units within said enclosure comprising: A planar, marginal inner surface adapted to confront a surface on the equipment enclosure; first and second panel elements extending respectively from adjacent the outer sides of said door angularly outward and toward one another to establish a front opening between the outer vertical edges of said panel elements; upper and lower door wall portions respectively connected to the upper panel element edge portions and the lower panel element edge portions with said panel outer vertical edges extending from said upper door wall portion to said lower door wall portion; and a central column extending between said upper wall portion and said lower wall portion which creates a pair of air passageways from said front opening between said panel element outer vertical edges and the inner surface of said door within said marginal inner surface; said panel elements presenting a continuous acoustic material surface at the inner sides which define a portion of said pair of passageways and said central column presenting an acoustic material surface at the side facing the said door inner surface; said central column presenting a continuous curved surface confronting the respective panel element which causes each of said pair of passageways to decrease in size and then increase in size from the front of said central column to the rear of said central column.
