摘要： Cooling apparatuses, cooled electronic modules and methods of fabrication are provided for fluid immersion-cooling of an electronic component(s). The cooled electronic module includes a substrate supporting the electronic component(s), and the cooling apparatus couples to the substrate, and includes a housing at least partially surrounding and forming a compartment about the electronic component(s). Additionally, the cooling apparatus includes a fluid and a deionization structure disposed within the compartment. The electronic component is at least partially immersed within the fluid, and the fluid is a water-based fluid. The deionization structure includes deionizing material, which ensures deionization of the fluid within the compartment. The deionization structure facilitates boiling heat transfer from the electronic component(s) to a condenser structure disposed in the compartment. Transferred heat is subsequently conducted to, for example, a liquid-cooled cold plate or an air-cooled heat sink coupled to the housing for cooling the condenser structure.

摘要： A cooling apparatus and method are provided for cooling one or more electronic components of an electronic subsystem of an electronics rack. The cooling apparatus includes a heat sink, which is configured to couple to an electronic component, and which includes a coolant-carrying channel for coolant to flow therethrough. The coolant provides two-phase cooling to the electronic component, and is discharged from the heat sink as coolant exhaust which comprises coolant vapor to be condensed. The cooling apparatus further includes a node-level condensation module, associated with the electronic subsystem, and coupled in fluid communication with the heat sink to receive the coolant exhaust from the heat sink. The condensation module is liquid-cooled, and facilitates condensing of 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.

摘要： A cooling apparatus and method are provided for cooling an electronics rack. The cooling apparatus includes an air-cooled cooling station, which has a liquid-to-air heat exchanger and ducting for directing a cooling airflow across the heat exchanger. A cooling subsystem is associated with the electronics rack, and includes a liquid-cooled condenser facilitating immersion-cooling of electronic components of the electronics rack, a liquid-cooled structure providing conductive cooling to electronic components of the electronics rack, or an air-to-liquid heat exchanger associated with the rack and cooling airflow passing through the electronics rack. A coolant loop couples the cooling subsystem to the liquid-to-air heat exchanger. In operation, heat is transferred via circulating coolant from the electronics rack, and rejected in the liquid-to-air heat exchanger of the cooling station to the cooling airflow passing across the liquid-to-air heat exchanger. In one embodiment, the cooling airflow is outdoor air.
