Method for rack-level air ducts integral to front and rear
is a method for rack-level air ducts that are integral to front and rear access
doors. Benefits include improved cooling of rack-mounted electronic equipment.
disclosed method includes the installation of an air duct at the inlet and
outlet to a mounting rack to enhance cooling (see Figure 1). These ducts also
serve as access doors to the front and rear of the electronics rack components,
such as servers, switches, and power supplies (see Figure 2).
centers are constructed so that cold air comes from floor vents and hot air
exits through ceiling ducts. The front access door provides airflow to the
electronic components without cooling the rest of the room unnecessarily.
Similarly, the rear duct directs the hot air to the ceiling for return to the
air conditioning (A/C) unit.
cold air from the floor is allowed to mix with warmer air in the room before
being taken into the rack components (see Figure 3). Similarly, hot air on the
exit side is allowed to mix with colder air in the room (see Figure 4).
The disclosed method enables cold air
to reach electronic rack components (servers and switches) without mixing with
warmer air. The result is improved component cooling.
