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： Apparatuses and methods are provided for blocking removal of an air-moving assembly from a chassis 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 chassis, and thereby prevents removal of the air-moving assembly from the chassis when in the operational state.

摘要： 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.

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： Tile assemblies are provided having first and second tile sections and an airflow control mechanism. The first tile section allows, in a cold air cooling mode, cold air from a cold air plenum of a data center to flow into a cold air containment aisle for supply to an electronics rack(s). The second tile section is associated with the first tile section to allow, in a failover cooling mode, ambient air external the cold air plenum to flow, via an air pathway through the second and first tile sections into the containment aisle. The airflow control mechanism is disposed within the air pathway to block cold air from the cold air plenum from passing through the second tile section in the cold air cooling mode, and to allow, in the failover cooling mode, ambient air to pass through the air pathway into the cold air containment aisle.

摘要： Liquid-cooled heat sink assemblies are provided which include: a thermally conductive base structure having a sidewall surface and a main heat transfer surface; and a manifold structure attached to the base structure, with the base structure residing at least in part within a recess in the manifold structure. Together, the base and manifold structures define a coolant-carrying compartment through which liquid coolant flows, at least in part, in a direction substantially parallel to the main heat transfer surface of the base structure, and at least one of the sidewall surface of the thermally conductive base structure or an opposing surface thereto of the manifold structure includes a continuous groove. A sealing member is disposed, at least in part, within the continuous groove, and provides a fluid-tight seal between the thermally conductive base structure and the manifold structure.

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.
