  • Cooling of data centers
    Publication number: 20040065097
    Abstract: In a cooling system for cooling racks in a data center, cooling fluid is circulated in the data center by a cooling device having a fan. In addition, this system includes a plenum having a plurality of returns and an outlet. The outlet of the plenum is in fluid communication with the fan and the plurality of returns are configured for removing the cooling fluid from the data center. Furthermore, the returns and are operable to vary a characteristic of the removal of the cooling fluid.
    Type: Application
