Appl. No.:

13/243156

Inventors:

Andrew R. Price - Austin TX, US
Rachid Kaina - Hot Springs AR, US
Mark C. Garnett - Dallas TX, US

Assignee:

DunAn Microstaq, Inc. - Dallas TX

International Classification:

H05K 7/20
F28F 27/02

US Classification:

361701, 36167953, 361698, 165 804, 165 805, 16510419, 16510422, 251 11, 25112901, 25112904, 137 14, 13759616

Abstract:

A heat exchanger structure including multiple fluid circuits, through which respective streams of a first fluid pass from a stream inlet to a stream outlet to transfer heat to or from a second medium. The fluid circuits are arranged into at least a first group and a second group, at least the first group consisting essentially of only fluid circuits that perform substantially similarly according to at least one selected performance criterion. A control sensor for at least the first group generates a signal representative of a parameter of the first fluid in the associated group. A valve for at least the first group is in fluid communication with of all the streams of the associated group so as to be able to control the flow of fluid through the streams of the associated group in parallel.

Appl. No.:

14/860749

Inventors:

- Austin TX, US
Mark Garnett - Austin TX, US

International Classification:

H05K 7/20

Abstract:

A system for cooling a plurality of servers containing heat generating electronic components, the system including a tank having a fluid inlet and a fluid outlet and a dielectric liquid. The dielectric liquid enters the tank via the fluid inlet at a first temperature equal to or greater than 90 degrees F. and exits the tank via the fluid outlet at a second greater than the first temperature.

Appl. No.:

Inventors:

- Austin TX, US
Mark Garnett - Austin TX, US

International Classification:

H05K 7/20

Abstract:

An apparatus for holding and cooling rack-mountable servers having heat-producing electronic components includes a tank, a volume of dielectric liquid coolant in the tank, mounting members that hold rack-mountable servers in the tank, one or more pumps, fluid velocity augmentations devices, and a liquid-to-liquid or liquid-to-refrigerant heat exchanger outside of the tank. The mounting members hold the rack-mountable servers in a vertical orientation within the tank such that the servers are commonly submersed in the volume of the dielectric liquid coolant. When a pump is operated to move the dielectric liquid coolant vertically across the heat producing components of the rack-mountable servers, a circuit is formed in which a first portion of heated dielectric liquid coolant is moved vertically upward across the heat producing components and then downward outside of the rack mountable servers in a passage external to the rack-mountable servers, while a second portion of heated dielectric liquid coolant flows out of the tank and through the liquid-to-liquid or liquid-to-refrigerant heat exchanger.
