Publication number: 20140049914Abstract: Dehumidifying cooling apparatus and method are provided for an electronics rack. The apparatus includes an air-to-liquid heat exchanger disposed at an air inlet or outlet side of the rack, wherein air flows through the rack from the air inlet to the air outlet side. The heat exchanger is positioned for air passing through the electronics rack to pass across the heat exchanger, and is in fluid communication with a coolant loop for passing coolant therethrough at a temperature below a dew point temperature of the air passing across the heat exchanger so that air passing across the heat exchanger is dehumidified and cooled. A condensate collector, disposed below the heat exchanger, collects liquid condensate from the dehumidifying of air passing through the electronics rack, wherein the heat exchanger includes a plurality of sloped surfaces configured to facilitate drainage of liquid condensate from the heat exchanger to the condensate collector.Type: ApplicationFiled: October 25, 2013Publication date: February 20, 2014Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Levi A.

Patent number: 8654302Abstract: A cooling assembly for an electronic image assembly having an open and closed gaseous loop. A closed gaseous loop allows circulating gas to travel across the front surface of an image assembly and through a heat exchanger. An open loop allows ambient gas to pass through the heat exchanger and extract heat from the circulating gas. An optional additional open loop may be used to cool the back portion of the image assembly (optionally a backlight). Ribs may be placed within the optional additional open loop to facilitate the heat transfer to the ambient gas. The cooling assembly can be used with any type of electronic assembly for producing an image.Type: GrantFiled: December 18, 2009Date of Patent: February 18, 2014Assignee: Manufacturing Resources International, Inc.Inventors: William Dunn, Timothy Hubbard

Publication number: 20140043762Abstract: An air-cooling apparatus is provided which includes a securing mechanism for holding two or more separate electronics racks in fixed relation adjacent to each other, and a multi-rack door sized and configured to span the air inlet or air outlet sides of the racks. The securing mechanism holds the electronics racks in fixed relation with their air inlet sides facing a first direction, and air outlet sides facing a second direction. The door includes a door frame with an airflow opening. The airflow opening facilitates the ingress or egress of airflow through the electronics racks, and the door further includes an air-to-liquid heat exchanger supported by the door frame, and disposed so that air flowing through the airflow opening passes across the heat exchanger. In operation, the heat exchanger extracts heat from the air passing through the separate electronics racks.Type: ApplicationFiled: October 16, 2013Publication date: February 13, 2014Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eric A.
