Method for rack-level air ducts integral to front and rear access doors
Disclosed 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.
Description
The 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).
Data 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.
Advantages
Conventionally, 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.
