Air washing for open air cooling of data centers

摘要

A data center system includes a housing to house servers arranged in electronic racks and an air supply system to receive contaminated air from an external environment of the housing. The datacenter system further includes a misting and cooling system to clean and cool the contaminated air. The misting and cooling system includes a cooling and cleaning chamber to receive the contaminated air and nozzles to spray liquid droplets into the contaminated air within the cooling and cleaning chamber. The liquid droplets collect and remove at least a portion of the particles contained in the contaminated air to generate non-contaminated air. The data center system further includes an airflow delivery system to generate an airflow from the non-contaminated air to cause the airflow to travel through the servers of the electronic racks to exchange heat generated by the servers due to operations of the servers.

主权项

1. A data center system, comprising:
a housing to house a plurality of servers operating therein, the servers being arranged in a plurality of electronic racks; an air supply system to receive contaminated air from an external environment of the housing, the contaminated air containing a plurality of particles; a misting and cooling system coupled to the air supply system to receive the contaminated air and to clean and cool the contaminated air, wherein the misting and cooling system includes
a cooling and cleaning chamber to receive the contaminated air from the air supply system, anda plurality of nozzles arranged to spray a plurality of liquid droplets into the contaminated air within the cooling and cleaning chamber, wherein the liquid droplets directly contact the particles of the contaminated air to collect and remove at least a portion of the particles contained in the contaminated air to generate non-contaminated air; and an airflow delivery system coupled to the misting and cooling system to generate an airflow from the non-contaminated air, to cause the airflow to travel through the servers of the electronic racks to exchange heat generated by the servers due to operations of the servers, and to exhaust the airflow carrying the exchanged heat to the external environment outside of the housing.
