Abstract
An apparatus for dampening vibrations generated by exhaust fans may include (1) at least one exhaust fan that (A) generates airflow across an array of storage devices that include rotating disks and (B) generates acoustic waves that produce propagating vibrations and (2) at least one acoustic attenuator that (A) includes a group of honeycomb-shaped openings that dampen the acoustic waves generated by the exhaust fan and (B) mitigates, by way of the honeycomb-shaped openings, interference to the rotating disks caused by the propagating vibrations produced by the acoustic waves. Various other apparatuses, systems, and methods are also disclosed.
Claims18
An apparatus comprising:
- at least one exhaust fan that:
- generates airflow across an array of storage devices that include rotating disks;
- and
- generates acoustic waves that produce propagating vibrations;
- at least one acoustic attenuator that:
- includes a group of honeycomb-shaped openings that dampen the acoustic waves generated by the exhaust fan;
- and
- mitigates, by way of the honeycomb-shaped openings, interference to the rotating disks caused by the propagating vibrations produced by the acoustic waves;
- and
- a cage that:
- houses the exhaust fan;
- and
- includes at least one additional group of honeycomb-shaped openings that are designed to shield electrical devices from electromagnetic waves generated by the exhaust fan.
A system comprising:
- at least one exhaust fan that:
- generates airflow across an array of storage devices that include rotating disks;
- and
- generates acoustic waves that produce propagating vibrations;
- at least one acoustic attenuator that:
- includes a group of honeycomb-shaped openings that dampen the acoustic waves generated by the exhaust fan;
- and
- mitigates, by way of the honeycomb-shaped openings, interference to the rotating disks caused by the propagating vibrations produced by the acoustic waves;
- a cage that:
- houses the exhaust fan;
- and
- includes at least one additional group of honeycomb-shaped openings that are designed to shield electrical devices from electromagnetic waves generated by the exhaust fan;
- and
- a chassis that houses:
- the array of storage devices;
- and
- the acoustic attenuator.
A method comprising:
- securing, within a cage removably coupled to an array of storage devices that include rotating disks, an exhaust fan that:
- generates airflow across the array of storage devices;
- and
- generates acoustic waves that produce propagating vibrations;
- incorporating, within a chassis that houses the array of storage devices, at least one acoustic attenuator that:
- includes a group of honeycomb-shaped openings that dampen the acoustic waves generated by the exhaust fan;
- and
- mitigates, by way of the honeycomb-shaped openings, interference to the rotating disks caused by the propagating vibrations produced by the acoustic waves;
- and
- incorporating, within the cage, at least one additional group of honeycomb-shaped openings that are designed to shield electrical devices from electromagnetic waves generated by the exhaust fan.
