    Abstract: Disclosed are designs to facilitate blind-mating of fluid connectors on servers and on racks that house the servers. The design includes two plates. A first plate has a connector channel to guide the connectors of the server through the first plate and spring structures to apply a force to push the connectors of the server toward the center of the connector channel. A second plate has positioning holes around its perimeter for mounting the connectors of the server using the force of the spring structures. The first plate is rotatable around a rotation axis to align the connectors of the server with the connectors of the rack. The second plate may have an elastic layer that is compressed to change a width of the second plate by inserting the second plate to the rack to automatically align the connectors of the server and of the rack in the horizontal direction.

    Abstract: A blind mating connection structure for servers is disclosed. On the server side, a connector module has fluid connectors to be blind mated to fluid connectors on rack manifolds in a server rack. The connector module is coupled to a sliding channel on the server. The connector module slides horizontally and vertically in response to movement of a positioning slider on the connector module. On the rack manifold side, a guiding module has an opening that receives the positioning slider when the server is installed in the server rack. The guiding module tapers down to a centering point midway between each rack manifold. As the server is slid into the server rack, the positioning slider follows the guiding module to the center point, moving the connector module into alignment with the fluid connectors on the rack manifold for blind mating.

In response to the detected velocity being below the outside air cooling threshold velocity, a first power cap is selected, based on the detected velocity being below the outside air cooling threshold velocity. In response to the detected velocity being at or above the outside air cooling threshold velocity, a second, higher, power cap is selected, based in part on the detected velocity being at or above the outside air cooling threshold velocity. Power capping is implemented to conserve available onboard power for IT equipment processing, based on availability of ram air cooling.

  • Patent number: 9042098
    Abstract: A cooling apparatus for an electronics rack is provided which includes a door assembly coupled to the electronics rack at an inlet or air outlet side of the rack. The door assembly includes: an airflow opening configured to facilitate ingress or egress of airflow through the electronics rack with the door assembly mounted to the rack; an air-to-coolant heat exchanger disposed so that airflow through the airflow opening passes across the air-to-coolant heat exchanger, the air-to-coolant heat exchanger being configured to extract heat from the airflow passing thereacross; and a vapor condenser configured to facilitate condensing of dielectric fluid vapor egressing from at least one immersion-cooled electronic component section of the electronics rack. The cooling apparatus, including the door assembly, facilitates air-cooling and immersion-cooling of different electronic components of the electronics rack.

  • Publication number: 20150131224
    Abstract: A method includes securing a primary cold plate to a secondary cold plate, wherein the primary cold plate is biased away from the secondary cold plate. The secondary cold plate is aligned with a circuit board having heat-generating components, wherein the primary cold plate is aligned with a processor. The method secures the aligned secondary cold plate to the circuit board with a first surface in thermal engagement with the heat-generating components, wherein the primary cold plate is pressed against the processor to overcome the bias, move the primary cold plate toward the secondary cold plate, position the primary cold plate in thermal engagement with the processor, and compress a thermal interface material between the primary and secondary cold plates. A cooling liquid is passed through a liquid cooling channel within the primary cold plate to draw heat from the processor and from the secondary cold plate.

  • Patent number: 9025332
    Abstract: A method is provided which includes providing a cooling apparatus for an electronics rack which includes a door assembly configured to couple to an air inlet side of the electronics rack. The door assembly includes: one or more airflow openings facilitating passage of airflow through the door assembly and into the electronics rack; one or more air-to-coolant heat exchangers disposed so that airflow through the airflow opening(s) passes across the heat exchanger(s), which is configured to extract heat from airflow passing thereacross; and one or more airflow redistributors disposed in a direction of airflow through the airflow opening(s) downstream of, and at least partially aligned to, the heat exchanger(s). The airflow redistributor(s) facilitates redistribution of the airflow passing across the air-to-liquid heat exchanger(s) to a desired airflow pattern at the air inlet side of the electronics rack, such as a uniform airflow distribution across the air inlet side of the rack.

  • Patent number: 9019704
    Abstract: Methods and means related to rejecting heat through thermal storage are provided. A heat sink includes internal cavities containing a phase-change material. Heat from a thermal load is rejected by flowing fluid coolant at a normal operating temperature. Failure of the fluid coolant system causes heat storage within the phase-change material at a temperature slightly greater than the normal operating temperature. Restoration of the fluid coolant system results in stored heat rejection and a return to a normal operating temperature. Normal operation of the thermal load can be performed while efforts are made to restore the fluid coolant system.

  • Publication number: 20150109730
    Abstract: Cooling apparatuses and methods are provided facilitating transfer of heat from a working fluid to a coolant. The cooling apparatus includes a vapor condenser which includes a condenser housing with a condensing chamber accommodating the working fluid and coolant, which are in direct contact within the condensing chamber and are immiscible fluids. The condensing chamber includes a working fluid vapor layer and a working fluid liquid layer; and a working fluid vapor inlet facilitates flow of fluid vapor into the condensing chamber, and a working fluid vapor outlet facilitates egress of working fluid liquid from the condensing chamber. A coolant inlet structure facilitates ingress of coolant into the working fluid vapor layer of the condensing chamber in direct contact with the working fluid vapor to facilitate condensing the vapor into working fluid liquid, and the coolant outlet structure facilitates subsequent egress of coolant from the condensing chamber.

  • Patent number: 9013872
    Abstract: A method of fabricating a cooling unit is provided to facilitate cooling coolant passing through a coolant loop. The cooling unit includes one or more heat rejection units and an elevated coolant tank. The heat rejection unit(s) rejects heat from coolant passing through the coolant loop to air passing across the heat rejection unit. The heat rejection unit(s) includes one or more heat exchange assemblies coupled to the coolant loop for at least a portion of coolant to pass through the one or more heat exchange assemblies. The elevated coolant tank, which is elevated above at least a portion of the coolant loop, is coupled in fluid communication with the one or more heat exchange assemblies of the heat rejection unit(s), and facilitates return of coolant to the coolant loop at a substantially constant pressure.
