Abstract:
1. A method of cooling electronic equipment mounted in an enclosure, the enclosure defining a front, two sides, and a rear, the method comprising: routing air from directly beneath the enclosure to an upper portion of the enclosure via a riser, the riser having a front facing toward the front of the enclosure but spaced apart therefrom, wherein routing air from beneath the enclosure to an upper portion of the enclosure includes routing air from beneath the enclosure through a collector and into the riser and further routing air through the riser to a plurality of ports; selectively routing air to electronic equipment mounted in the upper portion of the enclosure by opening or closing one or more of the plurality of ports disposed at the front of the riser and facing toward the front of the enclosure such that the air flows through the open ports toward the front of the enclosure, wherein routing air to the electronic equipment includes redirecting air flowing from the one or more ports, after it leaves such port, from a first direction of flow to a second direction of flow, the first direction of flow being substantially toward the front of the enclosure and the second direction of flow being generally toward a side of the enclosure and across a front of the electronic equipment, and wherein the plurality of ports are arranged in the upper portion of the enclosure; and exhausting heated air from the electronic equipment to an enclosure outlet.
