  • Cooling system and method for distributing cooled air
    Patent number: 6161612
    Abstract: A cooling system employing redundant system components is disclosed. The system includes multiple sets of heat: exchanger units, with each set being in fluid communication with a separate, independently operated fluid pump unit. The heat exchanger units are arranged in at least one row of heat exchanger units. The two sets of heat exchanger units are evenly interspersed with each other along the row of heat exchanger units so that a substantially uniform distribution of cooled air is provided in the event one fluid pump unit fails.

  • System and method for separating air flows in a cooling system
    Patent number: 6034873
    Abstract: A cooling system and method employing separation chutes and baffles is disclosed. The separation chutes separate the cooled air descending from a heat exchanger positioned above heat-generating equipment in an equipment room from heated air ascending from the heat-generating equipment. Separation of the airflows reduces turbulence and increases cooling efficiencies. The separation chutes are made of a variety of materials, both rigid and flexible, for a variety of applications.
