Appl. No.:

11/368778

Inventors:

Bruce E. Baker - Round Rock TX, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H05K 7/20
F24F 13/08
F24F 7/00

US Classification:

454184, 454259, 454353, 361687, 361695

Abstract:

A system, method, and apparatus for preventing exhaust backflow into a blower are disclosed. Embodiments may include a blower system with an invertible blower chassis having a blower exhaust to direct airflow from the blower chassis at an airflow angle. The system may also include a backflow damper frame attached to the blower chassis and positioned to receive airflow from the blower chassis and one or more vertical damper vanes rotatably attached to the backflow damper frame. Each damper vane may freely rotate between a first, closed position and a second, open position. The damper vanes may block airflow into the blower exhaust when in the closed position and may freely rotate to a position where the damper vanes are substantially parallel to the airflow from the blower exhaust. The damper vanes may each include a vane pin to rotatably attach to frame holes of the backflow damper frame.

US Classification:

Abstract:

An apparatus for positioning an electronics module in an equipment chassis with adequate pathways for the flow of cooling air across the module or across one or more adjacent modules, such as one or more blade server. The system includes an electronics module movably secured within a sub-assembly prior to installing the sub-assembly in a bay of a chassis. Ramps disposed within one or more bays of the chassis engage and position the electronics modules within the range of movement permitted by the sub-assembly when the sub-assembly has been installed in the chassis. Two bays having ramps positioned differently can receive the same sub-assembly or an identical sub-assembly and position the module differently. Therefore, the sub-assemblies are interchangeable while maintaining appropriate air flow pathways.
