Abstract: Apparatuses and methods are provided for blocking removal of an air-moving assembly from a housing when in operational state. The apparatus includes a protective louver assembly having a louver(s) and an interlock element(s). The louver(s) is disposed at an air inlet or an air outlet of the air-moving assembly, and pivots between an operational and a quiesced orientation, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The interlock element(s) is associated with the louver(s) to pivot with the louver(s) between the operational orientation and the quiesced orientation. In the operational orientation, the interlock element(s) blocks, at least in part, access to at least one fastener securing the air-moving assembly within the housing, and thereby prevents removal of the air-moving assembly from the chassis when in the operational state.

Abstract: Apparatuses and methods are provided for locking an air-moving assembly within a chassis when in operational state. The apparatus includes a locking louver assembly having a louver(s) and locking mechanism. The louver(s) is disposed at an air inlet or outlet of the air-moving assembly, and pivots between operational and quiesced orientations, dependent on presence or absence, respectively, of airflow through the air-moving assembly. The locking mechanism includes a keying element(s) affixed to the louver(s) to pivot therewith, which includes an elongated key(s) oriented in a first direction when the louver(s) is in operational orientation, and a second direction when in quiesced orientation. A key-receiving element(s) is associated with the chassis and includes a key opening(s) which receives and accommodates movement of the elongated key(s) between the first and second directions, and prevents removal of the air-moving assembly from the chassis with the key(s) oriented in the first direction.

Abstract: Electronics cooling assemblies are provided which include an air-cooled heat sink, an auxiliary air-moving device, and an airflow-blocking mechanism. The heat sink couples to one or more heat-generating electronic components, and dissipates heat from the electronic component(s) to a cooling airflow passing across the heat sink. The auxiliary air-moving device provides, when active, an increased flow rate of the cooling airflow across the heat sink. The airflow-blocking mechanism toggles between a passive airflow position and an active airflow position. In the passive airflow position, the airflow-blocking mechanism allows the cooling airflow to exhaust from the heat sink without passing through the air-moving device, and in the active airflow position, the airflow-blocking mechanism allows the cooling airflow to exhaust from the auxiliary air-moving device.

Abstract: Cooling apparatuses and methods of fabricating thereof are provided which facilitate pumped immersion-cooling of an electronic component(s). The cooling apparatus includes an enclosure having a compartment accommodating the electronic component(s), and dielectric fluid within the compartment at least partially immersing the electronic component(s). A liquid-cooled heat sink is associated with the enclosure to cool at least one cooling surface associated with the compartment, and facilitate heat transfer to the heat sink from the electronic component(s) via the dielectric fluid. A pump is disposed external to the compartment and in fluid communication therewith to facilitate pumped dielectric fluid flow through the compartment. The pumped dielectric fluid flow through the compartment enhances heat transfer from the electronic component(s) to the liquid-cooled heat sink via the cooling surface(s). In one implementation, the pumped dielectric fluid flow provides two-phase cooling to the electronic component(s) via flow boiling.

Abstract: Apparatuses and methods are provided for preventing removal of an air-moving assembly from a chassis when in operating state. The apparatus includes an interlock assembly having a slide element and one or more interlock elements. The slide element is slideably coupled to the air-moving assembly and resides in a first position when the air-moving assembly is in the operating state, and is slidable to a second position when the air-moving assembly is in a quiesced state. The slide element prevents removal of the air-moving assembly from the chassis in the first position, and allows removal of the air-moving assembly from the chassis in the second position. The interlock element(s) is associated with the slide element and prevents sliding of the slide element from the first position to the second position when the air-moving assembly is in the operating state.

Abstract: A heat sink structure is provided having fins mechanically altered dynamically to change and optimize the heat sink's performance based on certain environmental conditions. Specifically, the shape of fins of the heat sink structure is dynamically altered in response to environmental conditions that indicate the need for increased thermal performance by spreading the fins through a mechanical device dynamically, or by collapsing the fins to reduce pressure drop across a region when increased thermal performance is not needed.

Abstract: Apparatuses and methods are provided for facilitating air-cooling of, for instance, one or more electronics racks within a data center. The apparatus includes an air-moving assembly and one or more flywheels. The air-moving assembly includes a shaft, one or more mechanical fans coupled to the shaft to rotate, at least in part, with the shaft, and a motor coupled to the shaft to rotatably drive the shaft. The flywheel(s) is sized and coupled to the shaft of the air-moving assembly to store rotational energy, and to facilitate, for a specified period of time, continued rotation of the shaft during interruption in power to the motor. In one implementation, the flywheel(s) is sized and coupled to the shaft to facilitate, for the specified time period, continued rotation of the shaft at a specified percentage, or greater, rotational speed of the shaft compared with shaft speed when rotatably driven by the motor.

Abstract: Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.

Abstract: Cooling apparatuses, cooled electronic modules, and methods of fabrication are provided which facilitate heat transfer from one or more electronic components to a coolant. The cooling apparatus includes a coolant-cooled heat sink with a thermally conductive structure having a coolant-carrying compartment including a varying cross-sectional coolant flow area through which coolant flows in a direction substantially parallel to a main heat transfer surface of the structure coupled to the electronic component(s). The coolant-cooled heat sink includes a coolant inlet and a coolant outlet in fluid communication with the coolant-carrying compartment, and the coolant flow area of the coolant-carrying compartment decreases, at least in part, in a direction of coolant flow through the coolant-carrying compartment. The decreasing coolant flow area facilitates an increasing effective heat transfer coefficient between the main heat transfer surface and the coolant by, at least in part, accelerating the coolant flow within the coolant-carrying compartment.
