Apparatus for cooling electronic circuitry

Abstract

Described herein are systems, modes, and methods for an electronics enclosure cooling apparatus comprising a plurality of air intake holes located on at least one surface of the enclosure, a plurality of air exhaust holes located on at least one surface of the enclosure different from that of the surface wherein the air intake holes are located, an air plenum piece that comprises a substantially planar portion and a hole located on the substantially planar portion, the air plenum piece of such dimension and placement within the enclosure such that a first volume of the interior is created and a second volume of the interior is created, and wherein the air plenum piece is further adapted to create an air channel that substantially separates the first volume of the interior of the enclosure from the second volume of the interior, and wherein the first volume is in fluid engagement with the plurality of air intake holes, and further wherein the second volume is in fluid engagement with the plurality of air exhaust holes; and a fan located in coaxial alignment with the hole of the air plenum piece such that the fan is adapted to draw air from an exterior of the enclosure through the plurality of air intake holes, into the first volume, out through the second volume, and out through the plurality of air exhaust holes.

What is claimed is: 
     
         1 . An electronics enclosure cooling apparatus, comprising:
 a plurality of air intake holes located on at least one surface of the enclosure;   a plurality of air exhaust holes located on at least one surface of the enclosure different from that of the surface wherein the air intake holes are located;   an air plenum piece that comprises a substantially planar portion and a hole located on the substantially planar portion,
 the air plenum piece of such dimension and placement within the enclosure such that a first volume of the interior is created and a second volume of the interior is created, and wherein 
 the air plenum piece is further adapted to create an air channel that substantially separates the first volume of the interior of the enclosure from the second volume of the interior, and wherein 
 the first volume is in fluid engagement with the plurality of air intake holes, and further wherein 
 the second volume is in fluid engagement with the plurality of air exhaust holes; and 
   a fan located in coaxial alignment with the hole of the air plenum piece such that the fan is adapted to draw air from an exterior of the enclosure through the plurality of air intake holes, into the first volume, out through the second volume, and out through the plurality of air exhaust holes.   
     
     
         2 . The apparatus according to  claim 1 , wherein
 the plurality of air exhaust holes is not adjacent to the air intake holes such that substantially no exhaust air can be drawn into the plurality air intake holes.
