Abstract
An air-cooled enclosure of an information handling system has a chassis that receives at least one heat-generating functional component. An air mover is positioned within the chassis to move air within the chassis to convectively cool the at least one heat-generating functional component. An acoustic resonator includes a resonator body having a cavity sized to resonate at an acoustic frequency corresponding to a selected acoustic noise frequency, such as blade passage frequency, associated with the fan. The resonator body has an opening to the cavity that is directed toward and positioned a distance from the fan to receive and attenuate acoustic noise.
Claims15
An air-cooled enclosure comprising:
- a chassis that receives at least one heat-generating functional component of an information handling system;
- a fan positioned within the chassis to move air within the chassis to convectively cool the at least one heat-generating functional component;
- and
- an acoustic resonator comprising a resonator body having a cavity sized to resonate at an acoustic frequency corresponding to a selected acoustic noise frequency associated with the fan and having an opening to the cavity directed toward and positioned a distance from the fan to receive and attenuate acoustic noise.
An information handling system (IHS) comprising:
- at least one heat-generating functional component;
- and
- an air-cooled enclosure comprising:
- a chassis that receives the at least one heat-generating functional component;
- a fan positioned within the chassis to move air within the chassis to convectively cool the at least one heat-generating functional component;
- and
- an acoustic resonator comprising a resonator body having a cavity sized to resonate at an acoustic frequency corresponding to a selected acoustic noise frequency associated with the fan and having an opening to the cavity directed toward and positioned a distance from the fan to receive and attenuate acoustic noise.
A method comprising:
- making an acoustic resonator comprising a resonator body having a cavity sized to resonate at an acoustic frequency corresponding to a selected acoustic noise frequency of a fan;
- receiving at least one heat-generating functional component of an information handling system within a chassis;
- positioning the fan within the chassis to move air within the chassis to convectively cool the at least one heat-generating functional component;
- and
- aligning with and spacing away an opening to the cavity of the acoustic resonator from a face of the fan to respectively receive acoustic noise and to allow air flow to pass around the resonator body to the face of fan.
