1. A system for cooling an environmentally sealed enclosure, comprising:
- an air channel extending between a first surface of the enclosure and a second, opposing surface of the enclosure;
at least one interior heatsink forming a barrier between the air channel and an interior portion of the enclosure;
an external heatsink mounted to the enclosure;
a fan disposed in the air channel and adapted to force air to flow through the air channel; and
a plenum proximate the air channel to duct exhaust air away from the enclosure, wherein air flowing through the air channel cools the enclosure.

Abstract
A system for cooling an environmentally sealed enclosure. The system includes an air channel extending generally vertically from a top surface of the enclosure to a bottom surface of the enclosure, at least one interior heat sink forming a barrier between the air channel and an interior portion of the enclosure, a fan disposed in the air channel and adapted to force air to flow through the air channel, and a plenum proximate the air channel to duct exhaust air away from the enclosure, wherein air flowing through the air channel cools the enclosure. A method employs the system.

9. A system for cooling an environmentally sealed enclosure, comprising:
-
an air channel extending generally vertically from a top surface of the enclosure to a bottom surface of the enclosure; at least one interior heatsink forming a barrier between the air channel and an interior portion of the enclosure; a fan disposed in the air channel and adapted to force air to flow through the air channel; an air inlet disposed in the bottom surface of the enclosure proximate the air channel; an air outlet disposed in the top surface of the enclosure proximate the air channel; a rear heatsink mounted to a rear portion of the enclosure; and a plenum proximate the air channel to duct exhaust air away from the enclosure, wherein air flows into the inlet, through the air channel, is exhausted through the outlet, and is directed over the rear heatsink by the plenum to cool the enclosure. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method for cooling an environmentally sealed enclosure, comprising the steps of:
-
routing an air between a first surface of the enclosure and a second, opposing surface of the enclosure; installing at least one interior heatsink in the air channel to form a barrier between the air channel and an interior port ion of the enclosure; mounting a heatsink to an external portion of the enclosure; forcing air to flow through the air channel; and ducting exhaust air away from the enclosure, wherein air flowing through the air channel cools the enclosure. - View Dependent Claims (16)
