Abstract
A data storage enclosure can employ an acoustic baffle for the purpose of reducing performance degradation in a data storage device, such as a rotating medium hard disk drive. A storage enclosure may house a plurality of data storage devices and at least one cooling feature. One or more acoustic baffles may be positioned between the at least one cooling feature and the plurality of data storage devices. The acoustic baffle can separate a first sound pressure region that is proximal the at least one cooling feature from a second sound pressure region that is proximal the plurality of data storage devices.
Claims18
An apparatus comprising
- an acoustic baffle separating a first sound pressure region proximal a cooling feature of an enclosure from a second sound pressure region proximal a data storage device in the enclosure,
- the acoustic baffle comprising a plurality of protrusions each extending from a solid central column base to define a first plurality of air passages and a second plurality of air passages within a baffle housing, each air passage of the first plurality of air passages shaped to move air in a different direction than each air passage of the second plurality of air passages,
- wherein each protrusion of the plurality of protrusions extends from the solid central column to a wall of the baffle housing;
- and
- wherein a first protrusion of the first plurality of protrusions has a different shape than a second protrusion of the first plurality of protrusions.
A method comprising:
- positioning an acoustic baffle between a data storage device and a cooling feature in an enclosure, the acoustic baffle comprising a first plurality of apertures and a second plurality of apertures, each aperture of the first and second plurality apertures extending from a front side of a solid base through to a back side of the solid base to define separate air passages, each air passage of the first plurality of apertures shaped as a mirror image of each air passage of the second plurality of apertures about a mid-plane of the solid base to concurrently move air in opposite directions, the mid-plane positioned halfway between the front side and back side of the solid base;
- activating the cooling feature to move air and create a first sound pressure level proximal the cooling feature;
- and
- reducing the first sound pressure level to a second sound pressure level with the acoustic baffle, the second sound pressure level being proximal the data storage device.
