Vertical exhaust duct for electronic equipment enclosure

Abstract

An electronic equipment enclosure comprises a frame structure formed from a plurality of support posts and at least partially enclosed by a plurality of panels. The panels include at least side, top and back panels defining an enclosure having a top, a bottom and a rear thereof. The top panel includes an opening there through that is rectangular in shape. The equipment enclosure further comprises an exhaust air duct extending upward from the top panel of the enclosure. The exhaust air duct is rectangular in cross-section and is disposed in surrounding relation to, and in fluid communication with, the top panel opening. The exhaust air duct is adapted to segregate hot air being exhausted from the enclosure from cool air entering the enclosure, thereby improving thermal management of the enclosure.

         2 . A vertical exhaust duct for an electronic equipment enclosure, the vertical exhaust duct comprising:
 an inner duct section and an outer duct section;   wherein the inner duct section nests within the outer duct section;   wherein the inner duct section and the outer duct section are telescopically paired to facilitate adjustment of a height of the vertical exhaust duct; and   wherein at least one of the inner duct section and the outer duct section includes a pair of spaced apart elongated openings disposed at opposite sides thereof.   
     
     
         3 . The vertical exhaust duct of  claim 2 , wherein each of the pair of spaced apart elongated openings is adapted to receive a fastener. 
     
     
         4 . The vertical exhaust duct of  claim 3 , wherein the fastener includes a nut. 
     
     
         5 . The vertical exhaust duct of  claim 3 , wherein the fastener includes a bolt. 
     
     
         6 . The vertical exhaust duct of  claim 3 , wherein the fastener includes a spring-loaded pin. 
     
     
         7 . The vertical exhaust duct of  claim 2 , further comprising a base for securing one of either the inner duct section or the outer duct section to the electronic equipment enclosure. 
     
     
         8 . The vertical exhaust duct of  claim 2 , wherein one of either the inner duct section or the outer duct section includes a lower mounting edge. 
     
     
         9 . A vertical exhaust duct for an electronic equipment enclosure, the vertical exhaust duct comprising:
 first and second duct sections that are telescopically paired to facilitate adjustment of a height of the vertical exhaust duct;   wherein at least one of the first and second duct sections includes a pair of spaced apart elongated openings disposed at opposite sides thereof;   wherein the first duct section is nestably withdrawn into the second duct section to reduce the height of the vertical exhaust duct; and   wherein the first duct section is telescopically extended away from the second duct section to increase the height of the vertical exhaust duct.   
     
     
         10 . The vertical exhaust duct of  claim 9 , wherein each of the pair of spaced apart elongated openings is adapted to receive a fastener. 
     
     
         11 . The vertical exhaust duct of  claim 10 , wherein the fastener includes a nut. 
     
     
         12 . The vertical exhaust duct of  claim 10 , wherein the fastener includes a bolt. 
     
     
         13 . The vertical exhaust duct of  claim 10 , wherein the fastener includes a spring-loaded pin. 
     
     
         14 . The vertical exhaust duct of  claim 9 , further comprising a base for securing one of either the first duct section or the second duct section to the electronic equipment enclosure. 
     
     
         15 . The vertical exhaust duct of  claim 9 , wherein one of either the first duct section or the second duct section includes a lower mounting edge. 
     
     
         16 . A vertical exhaust duct for an electronic equipment enclosure, the vertical exhaust duct comprising:
 first and second duct sections, each having a generally rectangular cross-section;   wherein the generally rectangular cross-section of the first duct section is smaller than the generally rectangular cross-section of the second duct section such that the first duct section is nestable relative to the second duct section;   wherein the duct sections are telescopically paired to facilitate adjustment of a height of the vertical exhaust duct;   wherein at least one of the first and second duct sections includes a lower mounting edge to facilitate attachment to an electronic equipment enclosure; and   wherein at least one of the first and second duct sections includes a column of apertures, each aperture of the column of apertures being adapted to accommodate a fastener extending therethrough.   
     
     
         17 . The vertical exhaust duct of  claim 16 , wherein at least one of the first and second duct sections includes openings that are selectively alignable with openings of the other of the first and second duct sections so as to accommodate a fastener extending through both duct sections, thereby fixing the vertical height. 
     
     
         18 . The vertical exhaust duct of  claim 17 , wherein the fastener includes a nut.
