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.

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.

Abstract: A system, method and apparatus for detecting a fluid leak in a fluid based cooling system and purging the fluid therein under various conditions. The system, method and apparatus detect fluid levels in the cooling system, fluid pressure in the cooling system and fluid spraying and dripping from the cooling system. Upon an affirmative determination of low fluid levels, low fluid pressure or fluid spraying and dripping from one or more locations in the cooling system, the device automatically purges the fluid from the cooling system. Accordingly, in an overhead fluid-based cooling system, any damage to objects below from having fluid leaked thereon is minimized.

Abstract: When in operation, devices for telecommunications installed in rooms generate a considerable amount of heat. This takes place continuously, and a maximum temperature must not be exceeded. In order to obtain reserve time for an air cooling system having a reserve time system with a guaranteed low temperature level of the liquid for the reserve time system, an evaporator (2) for the air cooling system is provided with a liquid circuit (2b) which is connected with a liquid tank (7). Liquid is circulated continuously through the evaporator with the liquid circuit, where it is cooled by the cooling medium for the air cooling system, at the same time as the inside air is cooled by the same evaporator. The continuous cooling and circulation of the liquid in the tank ensures that there is always the coldest possible liquid available when the ordinary cooling system is not working.

Abstract: A system for cooling heat generating components in a closed space, for example, telecommunications equipment in rack cabinets in an enclosure includes a cooling unit operating with combined displacing air distribution and gravity air flow. Cooled air is distributed at low speed at a bottom of the closed space to contact the components from below. The cooled air displaces warmer air around and in the components for cooling. The warmer air moves upward in the space and is taken into the cooling unit at an upper intake opening. Air flow in the space is at a speed sufficiently low to avoid turbulence and mixing of the cooled and warmed air flows.
