    摘要: A data center cooling system has an indoor portion wherein heat is absorbed from components in the data center, and an outdoor heat exchanger portion wherein outside air is used to cool a first heat transfer fluid (e.g., water) present in at least the outdoor heat exchanger portion of the cooling system during a first mode. When an appropriate time has been reached to switch from the first mode to a second mode, the outdoor heat exchanger portion of the data cooling system is switched to a second heat transfer fluid, which is a relatively low performance heat transfer fluid (compared to the first fluid). It has a second heat transfer fluid freezing point, lower than the first heat transfer fluid freezing point, and sufficiently low to operate without freezing when the outdoor air temperature drops below a first predetermined relationship with the first heat transfer fluid freezing point.

    摘要: A coolant-conditioning unit is provided which includes a facility coolant path, having a facility coolant flow control valve, and a system coolant path accommodating a system coolant, and having a bypass line with a system coolant bypass valve. A heat exchanger is coupled to the facility and system coolant paths to facilitate transfer of heat from the system coolant to facility coolant in the facility coolant path, and the bypass line is disposed in the system coolant path in parallel with the heat exchanger. A controller automatically controls a regulation position of the coolant bypass valve and a regulation position of the facility coolant flow control valve based on a temperature of the system coolant, and automatically adjusts the regulation position of the system coolant bypass valve to facilitate maintaining the facility coolant flow control valve at or above a specified, partially open, minimum regulation position.

    摘要: A method of fabricating a cooling apparatus is provided to facilitate two-phase, immersion-cooling of one or more electronic components. The cooling apparatus includes a housing having a compartment within which dielectric fluid is disposed which facilitates immersion-cooling of the electronic component(s). A liquid-cooled heat sink is associated with the housing and cools a cooling surface exposed within the compartment. One or more pumps are disposed within the compartment and configured to pump dielectric fluid liquid within the compartment towards the cooling surface to facilitate cooling the liquid within the compartment below a saturation temperature of the dielectric fluid. The heat sink includes or is coupled to condensing and sub-cooling regions exposed within the compartment.

    摘要: A pressure control unit and method are provided for facilitating single-phase heat transfer within a liquid-based cooling system. The pressure control unit includes a pressure vessel containing system coolant, and a pressurizing mechanism associated with the pressure vessel. A coolant line couples system coolant in the pressure vessel in fluid communication with the coolant loop of the cooling system, and a regulator mechanism couples to the pressurizing mechanism to maintain pressure within the pressure vessel at or above a defined pressure threshold, thus maintaining pressure within the coolant loop above the pressure threshold. The defined pressure threshold is set to facilitate system coolant within the coolant loop remaining single-phase throughout an operational temperature range of the system coolant within the coolant loop. More particularly, the pressure threshold is set to ensure pressure of system coolant within the coolant loop remains above the coolant's saturation pressure at maximum operational temperature.
