Computer cabinet design

An arrangement for controlling the temperature in each of an array of cabinets comprising,

• a plurality of cabinets, each having side walls to isolate each cabinet from each other cabinet, top walls, a bottom wall, a back wall and a perforated front door;
• an elevated floor of tiles having cooling air thereunder under pressure;
• said cabinets arrayed on said tiles in groups of a predetermined number having their side walls substantially in contact;
• means for introducing communication and power wires into at least one of said cabinets;
• means for passing wire and cables from one cabinet to one or more adjacent cabinets through said walls;
• means for maintaining a low level of leakage of air around said wires and cables;
• means for regulating introduction of cooling air into said cabinets through said bottom walls.

A structure for cooling an enclosure containing heat producing elements, comprising:

• a cabinet having sides walls, and top and bottom walls to effectively isolate said cabinet from other object and environments;
• a plurality of fans in said top wall;
• means for limiting power consumption by said fans to less than 10% of the power consumed by equipment located in said cabinet;
• at least two additional panels selectively insertable into at least one opening in said top wall;
• a first of said panels being highly perforated, a second of said panels to block flow of gas therethrough, and a third of said panels having an induction fan secured thereto to draw air through said opening.

A structure for cooling a cabinet containing heat producing elements, comprising

• an enclosure having an interior with at least a top wall, a bottom wall and least one shelf located on a fixed position,
• said wall being highly perforated to permit cooling gas to flow therethrough,
• said bottom wall having at least one variable size opening therein,
• said one shelf positioned to prevent equipment from being located sufficiently close to said bottom wall to hinder flow of cooling gas through said variable size opening and to permit ready access to said variable size opening to adjust a size of said opening,
• said top wall having at least one opening therein,
• a plurality of panels selectively insertable into said at least one opening in the top wall,
• at least one of said panels to control flow of air through said opening,
• a tile floor on which said cabinet is supported,
• legs adapted to support said cabinet above the tile floor, and
• means for inducting cool ambient air into said cabinets,
• said enclosure having a highly perforated door, and
• means for controlling the flow of air through said door.
