ABSTRACT:
The built-in cooling system (12) is located centrally in the cabinet enclosure (10) and includes at least one plenum (22) having an interior chamber mounted in a roof area (24) of the enclosure (10). The plenum (22) is in fluid isolation from the air within the enclosure (10), but has at least one vent (66) being in fluid association with the ambient air outside of the enclosure (10). The plenum (22) is coupled to a heat exchanger column (20) located centrally in the enclosure (10) with an internal air passageway (78) with intake and exit ports (70, 72), and having an external air passageway (76) with intake and exit ports. The external air passageway (76) is in fluid association with the chamber of the plenum (22). At least one heat sink (40) is mounted above the electronic equipment in the plenum (22) between the external air passageway exit port (48) and the vent (66) of the plenum (22). The internal air in the heat exchanger column (20) is circulated by an internal air fan (26) and the external air therein is circulated by an external air fan (25).
