A vented cover includes a pair of cross-flow ventilation ducts each including an acoustic noise reduction lining. The ducts are "cross-flow" in that they cross and bypass one another. The cover is affixed to an enclosure containing components of a computer system and abuts against a panel of the enclosure having an airflow aperture. An air moving device (AMD) passes air through the enclosure from the ducts if the cover is an intake cover, and/or into the ducts if the cover is an exhaust cover. The ducts increase the air path length, and the acoustic absorbing surface, thereby increasing acoustic attenuation. Airflow resistance is reduced by reducing surfaces perpendicular and close to the area where air enters and by reducing sharp turns in the ducts. The cover has a relatively thin depth because the ducts cross and bypass each other in a very space efficient manner.

What is claimed is: 1. An apparatus, comprising: an enclosure for containing components of a system, the enclosure including a front panel, a rear panel, a top panel, a bottom panel, and two side panels; an air moving device for passing air through the enclosure; a vented cover affixed to the enclo
What is claimed is: 1. An apparatus, comprising: an enclosure for containing components of a system, the enclosure including a front panel, a rear panel, a top panel, a bottom panel, and two side panels; an air moving device for passing air through the enclosure; a vented cover affixed to the enclosure and abutted against a selected one of the panels having an airflow aperture, the vented cover including a pair of cross-flow ventilation ducts, wherein one of the cross-flow ventilation ducts crosses the other of the cross-flow ventilation ducts so that in an intermediate cross-section of the vented cover air moves in one of the cross-flow ventilation ducts in a direction substantially opposite to that in the other of the cross-flow ventilation ducts, and wherein at least a portion of each of the cross-flow ventilation ducts includes an acoustic noise reduction lining. 2. The apparatus as recited in claim 1, wherein the enclosure is configured for containing a computer system. 3. The apparatus as recited in claim 2, wherein the computer system is a server. 4. The apparatus as recited in claim 2, wherein the computer system is a data storage unit. 5. A computer system, comprising: an electronic component package; an enclosure for containing the electronic component package, the enclosure including a front panel, a rear panel, a top panel, a bottom panel, and two side panels; an air moving device for passing air through the enclosure; a vented cover affixed to the enclosure and abutted against a selected one of the panels having an airflow aperture, the vented cover including a pair of cross-flow ventilation ducts, wherein one of the cross-flow ventilation ducts crosses the other of the cross-flow ventilation ducts so that in an intermediate cross-section of the vented cover air moves in one of the cross-flow ventilation ducts in a direction substantially opposite to that in the other of the cross-flow ventilation ducts, and wherein at least a portion of each of the cross-flow ventilation ducts includes an acoustic noise reduction lining. 6. The computer system as recited in claim 5, wherein the electronic component package is a removable drawer containing electronic components, wherein the enclosure includes a frame for receiving a plurality of the removable drawers, and wherein the vented cover is hingedly affixed to the enclosure to permit access to the removable drawers when the vented cover is swung open. 7. The computer system as recited in claim 5, wherein the vented cover is an intake ventilation cover, and wherein the air moving device passes air through the enclosure from the cross-flow ventilation ducts of the intake ventilation cover. 8. The computer system as recited in claim 5, wherein the vented cover is an exhaust ventilation cover, and wherein the air moving device passes air through the enclosure into the cross-flow ventilation ducts of the exhaust ventilation cover. 9. The computer system as recited in claim 5, further comprising a second vented cover affixed to another selected one of the panels having an airflow aperture, the second vented cover including a pair of cross-flow ventilation ducts, wherein the direction of airflow in one of the cross-flow ventilation ducts of the second vented cover crosses the direction of airflow in the other of the cross-flow ventilation ducts of the second vented cover so that in an intermediate cross-section of the second vented cover air moves in one of the cross-flow ventilation ducts in a direction substantially opposite to that in the other of the cross-flow ventilation ducts, wherein at least a portion of each of the cross-flow ventilation ducts of the second vented cover includes an acoustic noise reduction lining, wherein the first and second vented covers are respectively intake and exhaust ventilation covers, and wherein the air moving device passes air through the enclosure from the cross-flow ventilation ducts of the intake ventilation cover and into the cross-flow ventilation ducts of the exhaust ventilation cover. 10. The computer system as recited in claim 9, wherein the intake ventilation cover and the exhaust ventilation cover are substantially identical parts. 11. The computer system as recited in claim 5, wherein the vented cover includes a plurality of pairs of cross-flow ducts extending generally parallel to one another. 12. The computer system as recited in claim 5, wherein the computer system is a server system and the enclosure includes a frame for receiving one or more servers. 13. The computer system as recited in claim 5, wherein the computer system is for data storage and the enclosure includes a frame for receiving one or more data storage units. 14. The computer system as recited in claim 5, wherein the computer system is a desktop computer system and the enclosure includes a tower frame. 15. The computer system as recited in claim 5, wherein the computer system is an individual rack unit configured to be received into a frame and the enclosure is the housing of the individual rack unit. 16. An apparatus, comprising: an enclosure for containing components of a system, the enclosure including a front panel, a rear panel, a top panel, a bottom panel, and two side panels; an air moving device for passing air through the enclosure; a vented cover affixed to the enclosure and abutted against a selected one of the panels having an airflow aperture, the vented cover including a first pair of cross-flow ventilation ducts, wherein at least a portion of each of the cross-flow ventilation ducts includes an acoustic noise reduction lining, wherein the air moving device passes air through the enclosure into or from the cross-flow ventilation ducts, and wherein the cross-flow ventilation ducts are configured so that in an intermediate cross-section of the vented cover air moves in one of the cross-flow ventilation ducts in a direction substantially opposite to that in the other of the cross-flow ventilation ducts. 17. The apparatus as recited in claim 16, wherein the vented cover includes a second pair of cross-flow ventilation ducts generally identical to the first pair, and wherein the second pair of cross-flow ventilation ducts is disposed in a stacked relationship above the first pair. 18. The apparatus as recited in claim 17, wherein the vented cover includes a third pair of cross-flow ventilation ducts generally identical to the first pair, and wherein the third pair of cross-flow ventilation ducts is disposed in a stacked relationship above the second pair. 19. The apparatus as recited in claim 16, wherein the cross-flow ventilation ducts are generally rectangular in the intermediate cross-section of the vented cover. 20. The apparatus as recited in claim 19, wherein the cross-flow ventilation ducts are generally triangular in one or more cross-sections of the vented cover outside the intermediate cross-section.
