Abstract

An apparatus is provided which includes a changeable cover assembly sized to cover, at least in part, an air outlet side of an electronics rack. The cover assembly, when positioned at the air outlet side of the rack, redirects and vents airflow egressing from the air outlet side. The cover assembly includes a frame and at least one vent cover. The frame has at least one opening through which air egressing from the electronics rack passes, and the vent cover(s) is coupled to the frame and overlies, at least in part, the opening(s) in the frame to facilitate redirecting and venting the air passing through the frame. The at least one vent cover is changeable to change a direction of the vented air. For instance, the vent cover(s) may be reversible, or otherwise adjustable or changeable, to change the direction of vented air egressing from the cover assembly.

First claim

What is claimed is:

1. An apparatus comprising:
a changeable cover assembly sized to cover, at least in part, an air outlet side of an electronics rack, the changeable cover assembly facilitating redirecting and venting airflow passing therethrough egressing from the air outlet side of the electronics rack, and the changeable cover assembly comprising:
a frame with at least one opening through which air egressing from the air outlet side of the electronics rack passes;
multiple different types of vent covers coupled to the frame and overlying, at least in part, the at least one opening in the frame to facilitate redirecting and venting the air passing therethrough, one vent cover of the multiple different types of vent covers being changeable to change a direction of vented air egressing from the changeable cover assembly, and an other vent cover of the multiple different types of vent covers directing at least two egressing airflow streams passing through the other vent cover to intersect upon being vented from the other vent cover to reduce momentum of the at least two egressing airflow streams; and
wherein the changeable cover assembly further comprises at least one electromagnetic compatibility screen within the at least one opening in the frame, the multiple vent covers overlying the at least one electromagnetic compatibility screen.

2. The apparatus of claim 1 , wherein the one vent cover is a reversible vent cover and is coupled to the frame at the air outlet side of the electronics rack above the other vent cover.

3. The apparatus of claim 2 , wherein the one vent cover comprises multiple fixed louvers facilitating redirecting of the air passing through the at least one opening in the frame, the multiple fixed louvers having, at least in part, a common orientation relative to the frame with the at least one opening.

4. The apparatus of claim 3 , wherein the changeable cover assembly is sized to substantially cover the air outlet side of the electronics rack.

5. The apparatus of claim 1 , wherein the frame isolates airflow passing through the one vent cover from airflow passing through the other vent cover.

6. The apparatus of claim 1 , wherein the one vent cover and the other vent cover of the multiple different types of vent covers are differently-sized.

7. The apparatus of claim 1 , wherein each vent cover of the multiple different types of vent covers receives a respective portion of the air passing through the at least one opening in the frame.

8. An apparatus comprising:
an electronics rack, the electronics rack comprising an air inlet side and an air outlet side; and
a changeable cover assembly coupled to the electronics rack at the air outlet side thereof, the changeable cover assembly facilitating redirecting and venting airflow passing therethrough egressing from the air outlet side of the electronics rack, the changeable cover assembly comprising:
a frame with at least one opening through which air egressing from the air outlet side of the electronics rack passes;
multiple different types of vent covers coupled to the frame and overlying, at least in part, the at least one opening in the frame to facilitate redirecting and venting the air passing therethrough, one vent cover of the multiple different types of vent covers being changeable to change a direction of vented air egressing from the changeable cover assembly, and an other vent cover of the multiple different types of vent covers directing at least two egressing airflow streams passing through the other vent cover to intersect upon being vented from the other vent cover to reduce momentum of the at least two egressing airflow streams; and
wherein the changeable cover assembly is sized to substantially cover the air outlet side of the electronics rack, and the frame is a door frame hingedly mounted to the electronics rack at the air outlet side thereof, and wherein the multiple different types of vent covers comprise an acoustically absorptive material, the acoustically absorptive material being selected to attenuate noise emanating from the electronics rack through the at least one opening in the frame when the changeable cover assembly is coupled to the air outlet side of the electronics rack.

9. The apparatus of claim 8 , wherein the one vent cover is a reversible vent cover and is coupled to the frame at the air outlet side of the electronics rack above the other vent cover, and comprises multiple fixed louvers having, at least in part, a common orientation relative to the frame, the multiple fixed louvers redirecting the air passing through the at least one opening in the frame.

10. A method comprising:
providing a changeable cover assembly sized to cover, at least in part, an air outlet side of an electronics rack, the changeable cover assembly, when positioned at the air outlet side of the electronics rack, facilitating redirecting and venting airflow passing therethrough egressing from the air outlet side of the electronics rack, the providing including:
providing a frame with at least one opening through which air egressing from the air outlet side of the electronics rack passes;
providing multiple different types of vent covers coupled to the frame and overlying, at least in part, the at least one opening in the frame to facilitate redirecting and venting the air passing therethrough, one vent cover of the multiple different types of vent covers being changeable to change a direction of vented air egressing from the changeable cover assembly, and an other vent cover of the multiple different types of vent covers directing at least two egressing airflow streams passing through the other vent cover to intersect upon being vented from the other vent cover to reduce momentum of the at least two egressing airflow streams; and
providing the changeable cover assembly further comprises providing at least one electromagnetic compatibility screen within the at least one opening in the frame, the multiple vent covers overlying the at least one electromagnetic compatibility screen.
