Axial fans are widely used for electronic cooling, but their use often results in unwanted noise. An axial fan is mounted to an enclosure, the sound radiation pattern becomes monopole-like since only one side of the fan is exposed to the exterior space; thus it radiates more efficiently than the same fan in free space. Purdue University researchers have developed a novel scheme that significantly reduces the sound power radiated by an axial fan mounted to a surface of an enclosure. Advantages: -Significantly reduces noise Potential Applications: -Electronics cooling |
