Date Jun. 29, 1995A 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. |
