摘要： A cooling apparatus and method are provided for cooling an electronic subsystem of an electronics rack. The cooling apparatus includes a local 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 electronic subsystem of the rack, and includes either a housing facilitating immersion cooling of electronic components of the electronic subsystem, or one or more liquid-cooled structures providing conductive cooling to the electronic components of the electronic subsystem. A coolant loop couples the cooling subsystem to the liquid-to-air heat exchanger of the local cooling station. In operation, heat is transferred via circulating coolant from the electronic subsystem and rejected in the liquid-to-air heat exchanger of the local cooling station to the cooling airflow passing across the liquid-to-air heat exchanger. In one embodiment, the cooling airflow is outdoor air.

摘要： A heat sink and method of fabrication are provided for removing heat from an electronic component(s). The heat sink includes a heat sink base and frame. The base has a first coefficient of thermal expansion (CTE), and includes a base surface configured to couple to the electronic component to facilitate removal of heat. The frame has a second CTE, and is configured to constrain the base surface in opposing relation to the electronic component, wherein the first CTE is greater than the second CTE. At least one of the heat sink base or frame is configured so that heating of the heat sink base results in a compressive force at the base surface of the heat sink base towards the electronic component that facilitates heat transfer from the electronic component. A thermal interface material is disposed between the base surface and the electronic component.

摘要： An air-to-coolant heat exchanger for an electronics rack is provided, which includes first and second tube segments, one or more connector segments, and a plurality of thermally conductive fins attached to the tube segments. The first tube segment includes a first inner tube positioned within a first outer tube, defining a first inner coolant-carrying channel and first outer coolant-carrying channel, and the second tube segment has a second inner tube positioned within a second outer tube, defining a second inner coolant-carrying channel and second outer coolant-carrying channel. The connector segment(s) couples in fluid communication at least one of the first and second inner coolant-carrying channels, or the first and second outer coolant-carrying channels. The heat exchanger is coupled to separately receive a first coolant and a second coolant, with the first coolant passing through the inner channels, and the second coolant through the outer channels.

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.
