Abstract: Controlling the temperature in a data center includes receiving sensory data corresponding to a temperature from a subsystem in a data center, processing the sensory data by a first agent in a hierarchy of agents to determine if the subsystems in the data center is operating within a predetermined temperature range, adjusting a delivery rate for a cooling fluid using the first agent to keep the temperature range of the subsystem within the predetermined temperature range, and requesting a second agent from the hierarchy of agents to process the sensory data when the first agent cannot keep the temperature range within the predetermined temperature range unless the second agent redistributes the cooling fluid being delivered. A third agent is used to vary the amount of cooling fluid output when at least the first and second agent cannot keep the subsystem operating within the predetermined temperature range.

The enclosure can include a reservoir, a condenser and a pump. Sprayers within the chamber are adjustably mounted on one or more brackets to allow each sprayer to be set for the individual height of its respective component. The enclosure can be readily removed from a computer system through a quick release connection. The computer system can include a condenser and pump to operate all its modular cooling systems, removing the condensing function from the individual modules.

Abstract: System and method for reducing temperature variation among components in a multi-component system. In this respect, component temperatures are controlled to remain relatively constant (approximately within 5° C.) with respect to other components, while allowing for multiple fluctuating heat loads between components. A refrigeration system possessing a variable capacity (speed) compressor and an electronic valve is utilized to control the flow of refrigerant through the refrigeration system. The temperature of the components is reduced by metering the mass flow rate of the refrigerant cooling the components to compensate for the heat load applied to the refrigeration system.

Abstract: A system and method for reducing temperature variation among components in a multi-component system. In this respect, component temperatures are controlled to remain relatively constant (approximately within 5° C.) with respect to other components, while allowing for multiple fluctuating heat loads between components. A refrigeration system possessing a variable capacity (speed) compressor and a thermostatic expansion valve is utilized to control the flow of refrigerant through the refrigeration system. The temperatures of the components are reduced by metering the mass flow rate of the refrigerant cooling the components to compensate for the heat load applied to the refrigeration system. The temperature variation among the components is reduced by supplemental heaters independently providing heat to each respective component.

Abstract: A semiconductor chip cooling system having a body that forms a cavity configured to create a spray chamber when conformingly adjoined to a chip, or to a substrate or printed circuit board carrying one or more chips. Inkjet-type sprayers are configured to spray cooling fluid down on the chip. A controller transmits a control signal to the sprayer to cause the sprayer to spray at a rate leading to the cooling fluid being vaporized by the semiconductor device. The cooling system uses cooling fluid surface tension forces to draw liquid cooling fluid up a porous member from the spray chamber back to the sprayers, to be sprayed again. The cooling system uses gravity and/or pressure within the spray chamber to direct vaporized cooling fluid upward from the spray chamber to a condenser. The condenser is configured to cool and condense the vapor. A reservoir is positioned below the condenser and above the sprayers so as to receive condensed vapor from the condenser and feed it to the sprayers.
