    Abstract: 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.

    Abstract: 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.

    Abstract: Energy efficient control of cooling system cooling of an electronic system is provided based, in part, on weighted cooling effectiveness of the components. The control includes automatically determining speed control settings for multiple adjustable cooling components of the cooling system. The automatically determining is based, at least in part, on weighted cooling effectiveness of the components of the cooling system, and the determining operates to limit power consumption of at least the cooling system, while ensuring that a target temperature associated with at least one of the cooling system or the electronic system is within a desired range by provisioning, based on the weighted cooling effectiveness, a desired target temperature change among the multiple adjustable cooling components of the cooling system. The provisioning includes provisioning applied power to the multiple adjustable cooling components via, at least in part, the determined control settings.

    Abstract: 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.

    Abstract: Apparatuses are provided for cooling an electronic component(s), which include a heat sink coupled to the electronic component(s), and having a coolant-carrying channel for a first coolant. The first coolant provides two-phase cooling to the electronic component(s), and is discharged from the heat sink as coolant exhaust, which includes coolant vapor. The apparatus further includes a node-level condensation module coupled to the heat sink to receive the coolant exhaust. The condensation module is cooled via a second coolant, and facilitates condensing the coolant vapor in the coolant exhaust. A controller automatically controls the liquid-cooling of the heat sink and/or the liquid-cooling of the node-level condensation module. A control valve adjusts a flow rate of the second coolant of the node-level condensation module, with the valve being automatically controlled by the controller based on a characterization of the coolant vapor in the coolant exhaust.
