Electrical equipment cabinet cooling

摘要

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.
