Abstract
Disclosed is an apparatus for cooling unvented cabinets housing electronic equipment. A fanning unit at a bottom portion of the cabinet draws air down through the spaces between printed circuit boards which include the electronic components. A plate installed on the inside of the cabinet door creates a duct to cause cooling of the air at the door surface as it flows upward for recirculation. A heat exchange element may also be provided in the space between the equipment mounted on both sides of the cabinet.
Claims11
A cabinet (10), comprising:
- a fan (22) mounted to said cabinet so as to be capable of drawing air in a vertical direction;
- means for providing recirculation of the air in a vertical direction opposite to the direction of air drawn by the fan, said means including a plate member (23) mounted to the inside of a door of said cabinet to form a duct (25) for recirculation of the air adjacent to a surface of said door so as to provide cooling of the air by said surface of the door, the fan being mounted to be capable of blowing air into the duct;
- a plurality of shelves (17, 18) mounted to said cabinet with a side positioned adjacent to said plate member and vertically spaced from said fan;
- and
- a heat exchanging element (30) mounted to said cabinet and positioned adjacent to a side of said shelves opposite to said door.

A cabinet (10), comprising:
- a fan (22) mounted to said cabinet so as to be capable of drawing air in a vertical direction;
- means mounted to said cabinet for directing the air in an opposite vertical direction;
- a plurality of vertically stacked shelves (e.g., 17 and 18) mounted to the cabinet with one side positioned adjacent to a door for providing access to said shelves;
- and
- a heat exchanging element (30) mounted to said cabinet and positioned adjacent a side of the shelves opposite to the door in a relationship to the fan so that air which is directed in the opposite vertical direction can be cooled by the heat exchanging element, said heat exchanging element comprising means (32) for drawing air from outside the cabinet through a plurality of compartments (36, 37, 38) in said element so as to provide a cooling surface (34) for the air in a space adjacent to said surface.
