Patent number: 10208981Abstract: Example air duct assemblies include a pliable air duct supported such that the duct is maintained in a generally expanded shape even when the duct is deflated. In some examples, a series of hangers suspend the duct from one or more cables, tracks or other type of overhead support. The hangers are spaced apart and distributed over the length of the duct, and each one contributes in pulling the duct taut in the duct's longitudinal direction.Type: GrantFiled: March 30, 2017Date of Patent: February 19, 2019Assignee: Rite-Hite Holding CorporationInventors: Cary Pinkalla, Jeff Logic, Kevin J.

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.Type: ApplicationFiled: February 19, 2018Publication date: June 21, 2018Inventors: Frank Heim, Kevin J.

Patent number: 9927140Abstract: Pliable-wall air ducts with internal expanding structures are disclosed. An example air duct system includes a shaft to be disposed within an air duct, to extend in a longitudinal direction, and to be in longitudinal compression. The air duct system also includes a plurality of ribs to be coupled to the shaft and to engage an inner surface of the air duct and a spring to be disposed within the air duct, the spring to be coupled to the shaft. The spring under stress being a contributing factor in both the shaft being in longitudinal compression and the air duct being in longitudinal tension.Type: GrantFiled: February 16, 2017Date of Patent: March 27, 2018Assignee: RITE-HITE HOLDING CORPORATIONInventors: Cary Pinkalla, Frank Heim, Kevin J.

Patent number: 9927139Abstract: 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.Type: GrantFiled: February 16, 2017Date of Patent: March 27, 2018Assignee: RITE-HITE HOLDING CORPORATIONInventors: Cary Pinkalla, Frank Heim, Kevin J.

Publication number: 20180077822Abstract: Cooling systems for devices arranged in rows are disclosed. An example cooling system includes an inflatable air duct to be positioned above a cold aisle defined between two rows of electronic equipment. The inflatable air duct is to be air permeable to deliver conditioned air into the cold aisle. The electronic equipment has fans to force cool air within the cold aisle through the electronic equipment to adjacent hot aisles on opposite sides of the two rows of the electronic equipment. The inflatable air duct to be spaced apart from the rows of computers such that the cold aisle is in unobstructed fluid communication with the adjacent hot aisles over top of the rows of electronic equipment. The conditioned air delivered from the inflatable air duct to substantially prevent a mixing of warm air in the hot aisles with the cool air in the cold aisle.Type: ApplicationFiled: September 9, 2016Publication date: March 15, 2018Inventors: Philip Sloan, Nicholas L. Kaufmann, Kevin J. Gebke, Frank Heim

Patent number: 9901011Abstract: An example cooling system for a datacenter is disclosed. The datacenter includes a plurality of computers arranged in a row within a building. The row of computers separates a cold aisle and a hot aisle. The row of computers defines an air passageway between the cold aisle and the hot aisle. The row of computers is associated with a top surface that is below and spaced apart from an overhead surface of the building to define a gap between the top surface and the overhead surface. The example cooling system includes an inflatable air duct to be disposed within the gap. The inflatable air duct has selectively an inflated state and a deflated state. The inflatable air duct filling more of the gap when the inflatable air duct is in the inflated state than when the inflatable air duct is in the deflated state.Type: GrantFiled: November 4, 2015Date of Patent: February 20, 2018Assignee: RITE-HITE HOLDING CORPORATIONInventors: Frank Heim, Kevin J.

Patent number: 9709193Abstract: Pliable air ducts with anti-condensation nozzles are disclosed. An example system includes a tubular duct comprising a pliable wall dividing an interior of the tubular duct from an exterior of the tubular duct. The system includes an outlet member to be attached to the pliable wall. The outlet member defines a main air passageway with a first flow resistance therethrough and places the interior of the tubular duct in fluid communication with the exterior of the tubular duct. The system includes a secondary air passageway with a second flow resistance therethrough. The secondary air passageway is defined by at least one of the outlet member or the pliable wall and extends from the interior of the tubular duct to the exterior of the tubular duct to define an airflow path proximate the outlet member. The second flow resistance is significantly greater than the first flow resistance.Type: GrantFiled: January 24, 2013Date of Patent: July 18, 2017Assignee: RITE-HITE HOLDING CORPORATIONInventors: Kevin J.
