Abstract
For cooling cabinets housing electrical equipment, fans are used for pulling internal air upwardly through the electronic equipment into a common space beneath the roof of the cabinet. Baffles within the space distribute the heated air in desired patterns across the inside roof surface and to ducts mounted on interior surfaces of external vertical walls of the cabinet for cooling the air by heat exchange through the roof surface and the vertical cabinet walls. In a second arrangement, an attic-like structure having a thermally insulated roof is mounted on the cabinet roof. External air is blown through the attic-like structure and across the cabinet roof for enhanced cooling of cabinet-heated air beneath the cabinet roof.
Claims9
A cabinet comprising vertically extending, first external walls and second and third horizontally extending walls at opposite ends of the cabinet for defining a cabinet interior space, a shelf extending generally parallel to said second wall sub-dividing said interior space into first and second spaces facing towards said second and third walls, respectively, said second space being for housing of heat generating equipment, and said first space being generally open for free circulation of air therewithin, a fan mounted on said shelf for blowing air from within said second space through an opening through said shelf into said first space and then into a preselected pattern of horizontal air streams directed towards ducts mounted on said first walls for causing flow of said air streams along internal surfaces of said vertical walls and then into said second space.
