28[] Disposed within the cabinet 10 is a rack 30 comprising spaced apart vertical supports 32, 34 supporting rails 36 upon which the rack-mounted equipment 37 may be supported. As seen in Fig. 1, the rack 30 is spaced at the sides from the cabinet 10 approximately the width of the vertical supports 32, 34.
29[] The air distribution arrangement 40 of the present invention as best seen in Figs. 1, 2, 4, and 5 includes an air box 42 constructed and arranged in the bottom of the cabinet 10 and adapted to communicate with the ambient through the grille 26 in the door 24. The air box 42 has on its sides brackets 25 for securing the air box 42 to the vertical supports 32,34 by suitable fastening means, such as a caged nut an bolt, as typically used in the industry. Disposed in the air box 42 are suitable fan means 44, 46, for example, a pair of axial fans. It will be understood by persons skilled in the art that other fans may be employed, provided they are capable of providing the air quantities and pressure necessary for a specific application. The air distribution arrangement 40 includes plenum structure for providing a plenum between the rack 30 and the door 24. The plenum structure includes side panels 50,51 and the top panel 52 operatively connected to one another. Preferably, the side panels 50,51 and the top panels 52 comprise complementary sections 50 a,b, 51 a,b, and 52 a,b which are adjustable with respect to one another to adjust the depth of the plenum.

The gasket 64 may be made from a suitable resilient material, such as polyurethane, which is suitably bonded or secured to the plenum structure. The gasket 64 may be bonded to the flanges 42a, 42 b, 42c, and 42 d on the air box 42, as well as the flange SOc on the side wall 50, the flange 52a on the top wall 52, and the flange S l c on the side wall 51 by a suitable adhesive (See Fig. 4). Alternately, the gasket 64 can be affixed to the flanges on the plenum structure by a fastener, such as a screw (not shown). The gasket 64 forms a seal between the rear of the front door 24 and the flanges on the plenum structure in the cabinet to seal the plenum from the ambient.
34[] In operation, the fan means 44,46 are energized to draw ambient air into air box 42 through the grille 26 in the front door 24 of the cabinet 10.
Panel 45 is provided in the cabinet 10 to adjust the opening of the air box 42 to the depth of the plenum formed between the faces of the rack-mounted devices 37, the door and the plenum structure 50, 51, 52. The coolest ambient air, normally that adjacent the floor, is drawn into the air box and then forced into the plenum at a rate of at least 850 cfm. The cooling air will flow upwardly in the plenum and be drawn into respective computer devices 37 for cooling same from the inlet opening or openings 38 in the front faces thereof that communicates with the plenum.
Excess pressure within the plenum can be relieved by pressure relief means 41,43, which may comprise slotted openings in the sides 50, 51 of the plenum structure.
The air discharged from the computer devices 37 will pass into the space between the rack-mounted equipment and the interior of the cabinet and be discharged from the vent openings 20 in the top 18 of the cabinet 10 or through the rear door 16.

The air discharged from the computer devices 37 will pass into the space between the rack-mounted equipment and the interior of the cabinet and be discharged from the vent openings 20 in the top 18 of the cabinet 10 or through the rear door 16.
35[] There has been provided by the air distribution arrangement of this invention a relatively inexpensive means for cooling rack-mounted equipment in a cabinet. A common size of cabinet used in the industry is thirty (30) inches deep by twenty four (24) inches wide by eighty four (84) inches high. The air distribution arrangement of the present invention is constructed and arranged to dissipate the _g_ heat load that might be generated within the cabinet during operation of the rack-mounted equipment. Within the industry a person of ordinary skill in the art would recognize that by adopting a 30 degree temperature differential from front to rear through the rack-mounted equipment and using fan means capable of producing 850 cfm of air in the plenum, a heat load of 8 KW can be accommodated. By maintaining a volume of at least 850 cfm, sufficient ambient air can be provided to cool such cabinet.
36[] Similarly, if an industry standard larger cabinet were used, for example, forty eight (48) inches deep by thirty (30) inches wide by eighty four (84) inches high, a larger fan means would be needed to pressurize the plenum and provide sufficient cooling air. Air volume on the order of 2000 cfm would accommodate a heat load on the order of 19 KW in the cabinet.
37[] As would be known to a person skilled in the art, the heat load to be removed from a cabinet can be calculated by the following formula: (cfm x TD) x 0.2931 = HL in watts. CFM is the cubic feet per minute of air from the fan means.
TD is the temperature differential across the rack-mounted equipment, for example, computers or servers, from front to rear. The term "0.2931 " is a constant.
TD is the temperature differential across the rack-mounted equipment, for example, computers or servers, from front to rear. The term "0.2931 " is a constant.
38[] In a modification, cooled air may be supplied to the cabinet through a duct 39 (Fig. 4) communicating a source of cooled air to the air box 42. The source of cooled air may be an air conditioning unit or a cold air conduit in the building. This arrangement will provide additional cooling capacity that may be desired or needed for some applications.
39[] In summary, the present invention provides a cabinet for rack-mounted equipment that generates heat with a low cost air distribution arrangement for effectively cooling the rack-mounted equipment. The air distribution arrangement includes plenum structure that fits into any conventional industry cabinet and that is adjustable to vary the plenum depth. The air distribution arrangement includes an air box containing at least one fan for drawing ambient air -()-from the room adjacent the floor and passing it to the plenum at a rate of at least 850 cfm. A resilient gasket is disposed between the front door of the cabinet and the plenum structure to minimize air loss from the plenum, thus providing a pressurized plenum. Excess pressure in the plenum can be relieved by pressure relief means in the plenum structure, for example, an opening or openings in the side walls of the plenum structure that communicates with the space between the rack-mounted equipment and the cabinet.
40[] While we have disclosed a presently preferred embodiment of the invention, it will be understood by persons skilled in the art that the invention may be otherwise embodied within the scope of the attached claims.
