  • Patent number: 8848371
    Abstract: 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.

  • Patent number: 8842435
    Abstract: A two-phase heat transfer assembly includes a cold plate having an impingement surface, an array of heat generating device coupled to the cold plate, and an array of spray nozzles. The impingement surface has an array of central hydrophilic regions. Each individual central hydrophilic region is surrounded by a hydrophobic perimeter. A wettability of the impingement surface gradually progresses from hydrophilic at each individual central hydrophilic region to hydrophobic at each hydrophobic perimeter. The array of heat generating devices is coupled to a heated surface of the cold plate such that the array of central hydrophilic regions is aligned with the array of heat generating devices. The array of spray nozzles is configured to direct coolant droplets toward the impingement surface. The wettability profile of the impingement surface of the cold plate causes the coolant droplets to move inwardly toward the individual central hydrophilic regions from each hydrophobic perimeter.

  • Publication number: 20140268572
    Abstract: A system includes an electronic device, a heat spreader with a vapor chamber attached to a bottom end of the electronic device, so that heat flows from the electronic device to the heat spreader, and a heat sink with microchannels running through it attached to a bottom end of the heat spreader, so that heat from the heat spreader flows through the heat sink and to an ambient. A method for cooling a device includes transferring heat generated by a device through a conductivity layer, spreading the heat through a heat spreader, transferring the heat from the heat spreader to a heat sink that contains microchannels, and releasing the heat from the heat sink into an ambient.

  • Patent number: 8837139
    Abstract: A flat radiator with flat type heat pipe and its application for portable computers is provided. The heat pipe in a radiator use tubular type and plate type structures. An air convective extended heat exchange surface surrounds and is over against the fan impeller, such that the radiator is extremely compacted, and the heat transport distance in heat pipe is shortened. Further introducing enhanced convective heat transfer structure and setting the fins according to the aerodynamics improve the heat dissipating capacity. The restrictions to a radiator when installing are reduced, which helps to implement the standardization of the radiator series. Also portable computers using the radiator are provided.

  • Patent number: 8820113
    Abstract: To reduce power consumption and more efficiently cool computing devices in a data center, an air supply unit supplies air from outside the data center to an air handling unit, which cools servers within the data center using the supplied air. Using air from outside the data center, rather than recirculating and cooling air from within the data center, reduces the power consumption of the data center. In an embodiment, a chiller and/or an evaporative cooling system are coupled to the air supply unit to allow further cooling of the outside air before it is circulated. Heat generated by the servers within the data center is collected, for example using thermal pathways coupled to server components, and used by the chiller in an absorption or adsorption process to further reduce power consumption of the data center and allow the air handling unit to further cool the outside air.
