Abstract

A data processor has air cooled components such as semiconductor memory cards that are held in several cabinets that are arranged about a central enclosure that contains blowers and other air cooling apparatus. For example, four cabinets can be located on each side of the central enclosure in the shape of a cross as seen from above. The lower half of the central enclosure forms a passageway for air that enters from below the enclosure (or from below a raised floor) through a conical inlet silencer. Cables that run between the cabinets are also located in this part of the central enclosure. A radial blower wheel is located at the end of this passageway, and the upper half of the central enclosure forms a plenum that is pressurized by the blower wh The plenum is acoustically lined.

Air Cooled Data Processing System With Central Enclosure Forming a Plenum And With Fans Located in Central Enclosure Or in an Adjoining Compartment

A data processor has air cooled components such as semiconductor memory cards that are held in several cabinets that are arranged about a central enclosure that contains blowers and other air cooling apparatus. For example, four cabinets can be located on each side of the central enclosure in the shape of a cross as seen from above. The lower half of the central enclosure forms a passageway for air that enters from below the enclosure (or from below a raised floor) through a conical inlet silencer. Cables that run between the cabinets are also located in this part of the central enclosure. A radial blower wheel is located at the end of this passageway, and the upper half of the central enclosure forms a plenum that is pressurized by the blower wh The plenum is acoustically lined. Air from the central plenum flows to each adjoining cabinet and is distributed through a channel that runs along the top of the cabinet. An orifice or a boost blower is located between the plenum and the channel, and the size of the orifice or the speed of the boost blower is adjusted to give each compartment an appropriate flow of cooling air. The boost blowers are arranged to be removable from the outside of the central enclosure and the system can remain operating while a boost blower is being replaced or repaired.
