A cabinet for electronics equipment, comprising: a compartment for
installing the electronics equipment; a door for accessing the
compartment; an outer duct mounted on an outer surface of the door for
directing exterior air around a heat exchanger core mounted in the door,
the heat exchanger core for transferring heat from interior air in the
compartment to the exterior air to thereby cool the interior air; an
exhaust duct extending over a top surface of the compartment and
pneumatically coupling with the outer duct when the door is in a closed
position, the exhaust duct for exhausting the exterior air and for
reducing solar loading on the top surface by transferring heat absorbed
by the exhaust duct to the exterior air passing therethrough; and, one or
more fans for forcing the exterior air in through the outer duct, around
the heat exchanger core, and out through the exhaust duct, the one or
more fans being mounted between the outer duct and the exhaust duct to
thereby attenuate noise emitted by the one or more fans.
