摘要： Composite heat sink structures and methods of fabrication are provided, with the composite heat sink structures including: a thermally conductive base having a main heat transfer surface to couple to, for instance, at least one electronic component to be cooled; a compressible, continuous sealing member; and a sealing member retainer compressing the compressible, continuous sealing member against the thermally conductive base; and an in situ molded member. The in situ molded member is molded over and affixed to the thermally conductive base, and is molded over and secures in place the sealing member retainer. A coolant-carrying compartment resides between the thermally conductive base and the in situ molded member, and a coolant inlet and outlet are provided in fluid communication with the coolant-carrying compartment to facilitate liquid coolant flow through the compartment.

摘要： Cooling apparatuses and methods of fabrication are provided which facilitate immersion-cooling of an electronic component(s). The cooling apparatus includes a drawer-level enclosure sized to reside within an electronics rack. The drawer-level enclosure includes a compartment which accommodates one or more electronic components to be cooled. A dielectric fluid is disposed within the compartment. The dielectric fluid includes a liquid dielectric which at least partially immerses the electronic component(s) within the compartment(s). A hinged, liquid-cooled heat sink is also disposed within the compartment of the enclosure. The heat sink operatively facilitates cooling the one or more electronic components via the dielectric fluid within the compartment, and is rotatable between an operational position overlying the electronic component(s), and a service position which allows access to the electronic component(s).

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Aspects include a method, system, and computer program product for determining a time to a threshold temperature of a device in a data center. A method includes measuring parameters for a device and the data center. A rate of change of temperature is determined based on the parameters. The change is compared to a change threshold. It is determined that a cooling system is operating below a threshold when the change is above the threshold. A first time is determined based on the rate of change of temperature and a machine learning model. The first and second time are compared, where the second time is a time to restore the cooling system above the threshold. A signal is transmitted when the first time is less than the second time. A cooling capacity is determined to have the temperature change of the device be equal to or less than the threshold.
