Abstract
In one embodiment, an apparatus includes a card chamber, an air intake, an airway, an exhaust plenum, and at least one fan. At least one electronics card can be supported in the card chamber. Ambient air from outside the apparatus can flow into the card chamber via the air intake. The airway is located across the card chamber from the air intake. Air flows substantially linearly across the card chamber from the intake to the airway. The exhaust plenum is located adjacent the card chamber and the airway. The fan is operable to draw air from the airway into the exhaust plenum.
Claims20
An apparatus comprising:
- a card chamber for locating at least one electronics card therein;
- an air intake through which ambient air from outside the apparatus can flow into the card chamber;
- an airway located across the card chamber from the air intake and into which air can flow substantially linearly across the card chamber;
- an exhaust plenum located adjacent the card chamber and the airway;
- and
- at least one fan operable to draw air from the airway into the exhaust plenum.
A method comprising:
- creating an area of lower than ambient air pressure in an air airway located across an air intake of a card chamber, so that air can flow substantially linearly across the card chamber;
- and
- drawing air from the airway into the exhaust plenum in a direction transverse to the flow of air across the card chamber.
