Described is a method for using acoustic agglomeration to collect pollution particulate at the air inlet of data centers in order to prevent corrosive contaminants from entering the data center and damaging the equipment within. The acoustic agglomeration may be done with a series of chambers each with different acoustic parameters (frequencies and decibel levels) to collect a range of particulate sizes.

Acoustic Agglomeration of Fine Particle Contaminants in Data Center Airflow Inlet

Particles with an aerodynamic diameter less than or equal to 2.5 ┬Ám are called PM2.5 or fine particles. These particles are a key contributor to thick haze pollution and can cause contamination and corrosion in servers. The problem is that the filters used in data centers to remove PM2.5 particles cause a pressure drop which impedes airflow, use of the filters is costly, and the filters have low efficiency for small particles.

    The core idea of this invention is the use of a series of acoustic chambers in the air inlet of a data center to agglomerate pollution particulates. This will minimize the amount of contaminants that can enter a data center and their corrosive effects on server products. A series of acoustic chambers with varying frequencies and sound pressure levels would be used to agglomerate particles of different sizes, including fine particles that are difficult to capture with current filter systems. This invention could replace filters currently used in data center air inlets or be used in conjunction with them.

    As air enters a data center, it would pass through a number of chambers, each with a specific frequency and sound pressure level targeted at removing a specific particle size. The chambers would be driven by directional acoustic transducers. The frequencies used could range from 0.5 to 20 kHz and sound pressure levels up to 160 dB. Higher sound pressure level...
