  • Patent number: 7404261
    Abstract: A dry-wet thermal management system for providing simultaneous spray cooling and dry cooling for a plurality of cards. The dry-wet thermal management system includes a chassis having a dry chamber and a spray chamber, a first opening within a rear portion of the chassis extending into the spray chamber, a second opening within the rear portion of the chassis extending into the dry chamber, and a main backplane secured and sealed to the rear portion of the chassis. Electronic cards may be electrically coupled within sockets of the main backplane within both the dry chamber and the spray chamber. The cards within the spray chamber are typically high heat flux components with increased cooling requirements and the cards within the dry chamber are typically low heat flux components with reduced cooling requirements. A spray cool system is within the spray chamber and a dry cool system is within the dry chamber.

  • Publication number: 20080066889
    Abstract: The present invention is a two-phase liquid cooling system that cools a plurality of electronic components connected in parallel. A pump delivers a cooling fluid, as a liquid, to a supply manifold wherein it splits into distinct branch lines. Preferably, the branch lines feed coolant to individual spray modules. The liquid coolant removes heat from the components to be cooled through evaporation. The resulting liquid and vapor mixture exits the spray modules via return branches. Each individual return branch feeds into a return manifold wherein the manifold is sized sufficiently for the separation of liquid and vapor under the influences of gravity. In addition, a heat exchanger is located within the return manifold and provides for the condensation of vapor. The heat exchanger may also provide liquid subcooling.

  • Patent number: 7313925
    Abstract: An atomizer for thermal management system for efficiently thermally managing one or more heat producing devices. The atomizer for thermal management system includes a housing having a coolant passage and a dispensing end, an orifice within the dispensing end, and an actuator manipulating a plunger within the housing. The plunger includes a head that is sealable within a recessed portion of the orifice to open or close the orifice. The coolant passes through the coolant passage into the orifice for spraying upon a heat producing device. The actuator may reciprocate so that the coolant spray emitted through the orifice is pulsating. The pulsing frequency may be increased to increase cooling or decreased to decrease cooling of the heat producing device.

  • Patent number: 7265976
    Abstract: A microchannel thermal management system for thermally managing a heat producing device. The microchannel thermal management system includes a housing having an interior surface, a cap having a plurality of microchannels attached to the interior surface of the housing, and an inlet port and an outlet port extending through the housing in fluid communication with the microchannels. Alternatively, the microchannels may also extend into the interior surface of the housing. The cap is preferably thermally attached to a heat producing device by a thermal interface layer. Thermally managed coolant enters the inlet port passing through the microchannels conducting heat transferred to the cap by the heat producing device and exits through the outlet port.

  • Publication number: 20070199340
    Abstract: The present invention uses multiple global cooling chambers for providing liquid cooling to a plurality of electronic components. The global cooling chambers utilize a non-electrically conductive fluid which is in direct contact with the components to be cooled. The system provides very effective heat transfer rates, environmental isolation of the electronics components and can be deployed in a wide range of applications. Multiple global cooling chambers allows for the hot swapping of cards during operation of the system.

  • Publication number: 20070193285
    Abstract: A two-phase liquid cooling system includes an active venting system for regulating an amount of non-condensable gas within the cooling system. Various venting structures may be used to remove gases from the cooling system, some of which are designed to remove the non-condensable gases and avoid removing the vapor-phase coolant. A control system activates the venting system to achieve a desired pressure, which may be based on measured process conditions within the cooling system. A venting and refilling system may serve multiple cooling systems in a parallel arrangement. A return path of the cooling system can be tested for coolant leaks by increasing the pressure in the return path and placing a coolant detector near the path.

  • Patent number: 7159414
    Abstract: The present invention is a coldplate hotspot spray cooling system that cools an electronic component creating a varying amount of heat across its surfaces. Liquid coolant is dispensed upon a spray pin protruding from a base wherein the liquid creates a very high heat absorbing evaporative thin film. The spray pin is located over an area of the chip that produces a large heat flux, typically referred to as a hotspot. The small size and isolation of the spray pin provides the ability to generate very large heat fluxes. Multiple spray pins are possible.
