Abstract: Cooling systems for devices arranged in rows are disclosed. An example cooling system for a datacenter in a building includes a supply air duct to extend lengthwise along a first aisle within the building. The first aisle is defined between a first row of computers and a second row of computers. The first row of computers provides passage of a first current of air from the first aisle to a second aisle on an opposite side of the first row of computers. The supply air duct is to be positioned with an upper section that is higher than a top surface associated with the first and second rows of computers. The cooling system includes a first wing to extend from the supply air duct toward the first row of computers, and a second wing to extend from the supply air duct toward the second row of computers.

Abstract: Example air ducts comprising pliable tubular sidewalls are provided with example internal frameworks that hold the duct in a generally expanded shape even when the duct is depressurized. The framework tensions the pliable sidewall material along the length of the ducts to keep the material taut. In some examples, the framework is restrained within the duct such that the duct's sidewall, being in tension, holds the framework in compression longitudinally. Thus, in the longitudinal direction, the duct is in tension and the framework is in compression. To prevent the framework from buckling under the compressive force, some example frameworks comprise a central longitudinal shaft with a plurality of radial spokes and rings that help hold the shaft straight. In some examples, the rings also help hold the duct radially expanded.
