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.

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： 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.

摘要： A cooled electronic system and cooling method are provided, wherein a field-replaceable bank of electronic components is cooled by an apparatus which includes an enclosure at least partially surrounding and forming a compartment about the electronic components, a fluid disposed within the compartment, and a heat sink associated with the enclosure. The field-replaceable bank extends, in part, through the enclosure to facilitate operative docking of the electronic components into one or more respective receiving sockets of the electronic system. The electronic components of the field-replaceable bank are, at least partially, immersed within the fluid to facilitate immersion-cooling of the components, and the heat sink facilitates rejection of heat from the fluid disposed within the compartment. In one embodiment, multiple thermal conductors project from an inner surface of the enclosure into the compartment to facilitate transfer of heat from the fluid to the heat sink.

摘要： Cooling apparatuses, cooled electronic modules, and methods of fabrication are provided which facilitate heat transfer from an electronic component(s). The cooling apparatus includes a liquid-cooled heat sink with a thermally conductive structure having a coolant-carrying compartment including a region of reduced cross-sectional coolant flow area. The heat sink includes a coolant inlet and outlet in fluid communication with the compartment, and the region of reduced cross-sectional coolant flow area provides an increased effective heat transfer coefficient between a main heat transfer surface of the conductive structure and the coolant. The cooling apparatus further includes a coolant loop coupled to the coolant inlet and outlet to facilitate flow of coolant through the coolant-carrying compartment, and a coolant filter positioned to filter contaminants from the coolant passing through the heat sink. The coolant filter has a larger cross-sectional coolant flow area than the region of reduced cross-sectional coolant flow area.

摘要： Methods are presented for facilitating dissipation of heat generated by one or more electronic components. The methods include providing a coolant-cooled heat sink and a thermostat-controlled valve. The heat sink includes one or more coolant-carrying channels and one or more valve wells intersecting the channels. The thermostat-controlled valve is disposed, at least partially, within a respective valve well so as to intersect a respective coolant-carrying channel, and includes a valve disk and a thermal-sensitive actuator mechanically coupled to rotate the valve disk. The valve disk is rotatable between an open position where coolant is allowed to flow through the respective coolant-carrying channel, and a closed position where coolant is blocked from flowing through the respective channel. The actuator rotates the valve disk between the open position and the closed position, dependent on heating of the thermal-sensitive actuator by the electronic component(s).

摘要： Methods are provided for automated coolant flow control for, for instance, facilitating cooling of multiple different electronic systems. The methods include, for instance, automatically controlling coolant flow to a plurality of coolant circuits, and for a coolant circuit i of the coolant circuits: automatically determining the heat load transferred to coolant flowing through coolant circuit i, and automatically controlling coolant flow through coolant circuit i based on the determined heat load transferred to the coolant. The different coolant circuits may have the same or different coolant flow impedances, and flow through the different coolant circuits may be controlled using different heat load-to-coolant ranges for the different circuits.
