Patent number: 8848371Abstract: A cooling system has an inlet plenum and at least one cooling channel which communicates with the inlet plenum. The cooling channel passes adjacent to a component to be cooled from an upstream inlet to a downstream outlet. A pair of electrodes are positioned adjacent the inlet to create an electric field tending to resist a bubble formed in an included dielectric liquid from moving in an upstream direction due to a dielectrophoretic force. Instead, a dielectrophoretic force urges the bubble in a downstream direction.Type: GrantFiled: October 1, 2012Date of Patent: September 30, 2014Assignee: Hamilton Sundstrand CorporationInventor: Matthew Robert Pearson

Patent number: 8842434Abstract: A server rack heat dissipation system for a server including an electronic component comprises a first and a second heat dissipation assembly. The first heat dissipation assembly includes a first heat exchanger and a first pipeline. The first heat exchanger is inside the server rack and in thermal contact with the electronic component. The first pipeline is in thermal contact with the first heat exchanger and has a first coolant. The second heat dissipation assembly includes a second heat exchanger. The second heat exchanger is inside the server rack and in thermal contact with the first pipeline. The second heat exchanger can remove the heat of the electronic component in the first coolant in advance. Accordingly, the time of the first coolant being maintained in a vapor phase can be shortened, so that a power the fluid driving device used for driving the first coolant is reduced.Type: GrantFiled: March 1, 2012Date of Patent: September 23, 2014Assignee: Inventec CorporationInventors: Chien-An Chen, Kai-Yang Tung

Publication number: 20140268549Abstract: A device for cooling an electronic component in a data center is provided. The device includes a closed loop, a first area, a second area, and a barrier. The closed loop includes a first portion and a second portion. The liquid flows around the closed loop. The first area is configured for dissipating heat from the electronic component in the data center to liquid in the first portion of the closed loop. The second area is configured for removing heat from the liquid in the second portion of the closed loop by receiving ambient air, which moves across the second portion, from outside the data center and configured for outputting the ambient air with the dissipated heat from the second area and the data center. The barrier is configured for preventing the ambient air from entering the first area.Type: ApplicationFiled: October 26, 2011Publication date: September 18, 2014Applicant: Hewlett-Packard Development Company, L.P.Inventors: Matt Neumann, Timothy Michael Rau

Patent number: 8830672Abstract: A computer system includes a rack-mountable server unit with a closed server housing. The server housing has a channel with a recessed channel wall in conductive thermal communication with a processor or other heat-generating component. An elongate conduit is received into the channel of the server housing in conductive thermal communication with an external surface of the server housing. The server is cooled by conductive fluid flow through the conduit, with no appreciable airflow through the server housing. The system may be operated in an optional burst cooling mode, wherein a volume of cooling fluid is trapped in the conduit for a period of time before being quickly released.Type: GrantFiled: July 27, 2012Date of Patent: September 9, 2014Assignee: International Business Machines CorporationInventors: Shareef F.

Publication number: 20140218861Abstract: An immersion server includes: a first surface that is exposed when the server is submerged within a cooling liquid; and at least one vapor bubble deflector physically abutting the first surface and extending away from the first surface at an angle. The deflector divides the first surface into an upper segment and a lower segment when the server is upright. When the server is submerged, the cooling liquid surrounding the lower segment absorbs sufficient heat to evaporate and generate vapor bubbles rising to the liquid surface. The vapor bubble deflector deflects the rising vapor bubbles away from the surface of the upper segment. This enables superior liquid contact with heat dissipating components at the upper segment and better cooling of those components. The deflector can be a device-level deflector separating two or more components or a component-level deflector separating a lower segment from an upper segment of a single component.Type: ApplicationFiled: February 1, 2013Publication date: August 7, 2014Applicant: DELL PRODUCTS L.P.Inventors: Austin Michael Shelnutt, James D.

Patent number: 8797739Abstract: A self-circulating heat exchanger apparatus for dissipating heat from an electronic assembly. An enclosure defines a closed-loop circulation path for coolant. An electronic assembly capable of generating heat is installed into a vertical portion of the enclosure such that heat from the electronic assembly causes coolant in the vertical portion to rise, thereby inducing self-circulation of the coolant in the enclosure. The electronic assembly is coated with a combination of silicon nitride and PARYLENE® in order to protect electronic components from water based coolants such as a mixture of ethylene glycol and water.Type: GrantFiled: June 18, 2012Date of Patent: August 5, 2014Assignee: Delphi Technologies, Inc.Inventors: Scott D.
