Abstract: The integrated circuit includes a mounting portion configured to attach at least a portion of the integrated circuit to a manifold of a liquid-cooled server. The integrated circuit also includes a temperature sensor configured to detect a temperature of the manifold. The integrated circuit also includes a leak detection sensor configured to detect whether a liquid exists in an area proximate the manifold. The integrated circuit also includes a communication system configured to communicate the temperature of the manifold and/or whether the liquid exists in the area. The integrated circuit is a compact solution usable to determine information (e.g., inlet temperature, outlet temperature, differential temperatures, leaks, etc.) about a server in which it is implemented.

Abstract: The self-centering floating fluid coupler includes a body having a first port and one or more second ports in communication with the first port. The fluid coupler also includes a housing assembly surrounding the body. The housing assembly includes a first opening exposing the first port of the body and a second opening exposing the one or more second ports of the body. The fluid coupler further includes one or more bias members disposed within the housing and configured to bias the body to a central position within the housing assembly. The body is able to move within the housing assembly to accommodate misalignments between the first port and a corresponding connection location (e.g., a mating fitting). Furthermore, the body is biased back to the central position when connections are removed. Accordingly, the fluid coupler allows for a broad range of misalignments.

Abstract: A system and apparatus are provided for containing leakage in a cooling system, thereby preventing the leakage from contacting sensitive electronic devices. A containment tray is configured to cover the surface of one or more cold plates and the electronic devices beneath. The containment tray includes an access port in the base of the containment tray for each cold plate. Hydraulic fitting connections on each cold plate pass up through the access ports and are connected to a coolant supply system. The containment tray is clamped to the cold plates with the gaskets creating a seal between the cold plate and the containment tray. Thus, the containment tray is positioned to collect leakage from the coolant supply system connected to an above the cold plates and electronic devices beneath.

Abstract: A latch is provided for holding stacked expansion boards above a mother board that includes an auto-lock feature that triggers when an expansion board is installed and is reset when the board is removed. The latch includes a trigger arm above which a first latch slider and a second latch slider are stacked. Movement of the trigger arm caused by placement of an expansion board releases the first latch slider to an extended position that holds the expansion board in place. Downward movement of a second expansion board against the second latch slider forces the second latch slider back until the second expansion board is received by a gap between the first and second latch sliders.

Abstract: An apparatus is provided for securing a first chassis within a second chassis in a manner than completes a blind connection and maintains that connection without the use of tools. A cam tooth on an arm rotating with respect to the first chassis engages a striker on the second chassis and, with rotation of the arm toward the first chassis, draws the first chassis into the second. The arm is attached to a handle including a cam hook that rotates to engage a striker of the first chassis. With rotation of the cam hook, the striker draws the handle toward the first chassis, the resulting movement of the arm toward the first chassis causing the arm to rotate and the cam tooth to draw the first chassis into the second.

Abstract: The ratcheting cam-latch includes a cam that is configured to rotate about a cam rotation-axis. The cam has a cam-in surface with a concave curvature configured to interface with a cam-in feature on a server rack. The cam-in surface has a decreasing radius from the cam rotation-axis in a first direction around the cam rotation-axis. The ratcheting cam-latch also includes a handle mount configured to rotate about a handle rotation-axis that is parallel to the cam rotation-axis and a ratchet disposed between the handle mount and the cam. The ratchet is configured to, responsive to a first rotational force on the handle mount in the first direction, cause the cam to turn in the first direction and, responsive to a second rotational force on the handle mount in a second direction that is opposite the first direction, not cause the cam to turn in the second direction.

Abstract: The apparatus includes a body having one or more threaded holes and a pin for each threaded hole. Each pin has a screw configured to thread into one of the threaded holes and abutment surfaces configured to abut against loosened cooling structure mounting screws of a cooling structure. The apparatus further includes a plurality of arms coupled to the body with hooks configured to extend underneath the cooling structure. When the apparatus is mounted to the cooling structure, threading the screws into the threaded holes causes the body and arms to lift relative to the pins. Since the pins are abutted against the cooling structure mounting screws and the hooks are underneath the cooling structure, the cooling structure lifts from a base board on which it was mounted. By using multiple pins, even cooling structures with many interfaces can be easily separated.

Abstract: An automatically-locking latch includes a first slider having a linking pin, a trigger having a tooth, and a second slider having a catch and a first ramp. The trigger is connected to the first slider such that the trigger is biased toward a third direction. The second slider is connected to the bracket and biased in the third direction to a latched position. On insertion of the latch-equipped device into a rack, the second slider rises up and over a catch. On reaching the desired position, the second slider descends to a latched position behind the catch. To release, a user depresses the first slider, causing the linking pin to ride against the first ramp and urge the second slider upward to an unlatched position, at which point the latched device may be removed from the rack.

Abstract: A position lock is provided for a rack assembly. The position lock includes a cam operable to rotate in a push direction. When the cam is rotated in the push direction, the cam is operable to push against an inner rail of the rack assembly to linearly translate the inner rail along the rack assembly in a frontward direction.

Abstract: A cam latching device is provided for a computing system being installed in a rack. The cam latching device can include a cam and a locking mechanism. The cam includes a handle portion and an engagement portion. The cam includes a locking surface formed thereon. Rotation of the handle portion causes the engagement portion to rotate. The locking mechanism includes a push component and a lock. The push component abuts against a button disposed on a rail of the rack as the computing system translates along a longitudinal axis. When the push component slides against the button, the locking mechanism transitions from a locked configuration to an unlocked configuration. In the locked configuration, the lock abuts against the locking surface to prevent the rotation of the cam. In the unlocked configuration, the lock is retracted away from the locking surface so that the cam is rotatable.

Abstract: A canister for coupling a plurality of servers to a server rack is described herein. The canister includes an influent rigid manifold and an effluent rigid manifold that have respective pluralities of quick-disconnect (QD) fittings arranged in fixed orientations and configured to couple with corresponding QD fittings on the servers. The canister further includes an influent canister QD fitting coupled with the influent rigid manifold and configured to couple with an influent soft manifold of the server rack. The canister also includes an effluent canister QD fitting coupled with the effluent rigid manifold and configured to couple with an effluent soft manifold of the server rack. The canister is one of many canisters configured to mount to the server rack. By using multiple canisters and the soft manifolds, many liquid-cooled servers may be implemented within the server rack without necessitating high tolerance manufacturing of the manifolds.

Abstract: A manifold system is provided. A secondary manifold is operable to be fluidly coupled with a liquid cooling system for each of a plurality of computing devices. The secondary manifold is configured to be positioned above the plurality of computing devices. A containment tray is disposed between the secondary manifold and the computing devices. The containment tray is operable to receive fluid that leaks from the secondary manifold.

Abstract: A fluid reservoir device is provided. A body forms a reservoir operable to receive fluid. The body is operable to transition between a contracted configuration and an expanded configuration such that the body in the expanded configuration expands a volume of the reservoir. A transition component is operable to transition the body between (1) the expanded configuration to the contracted configuration as a computing device fluidly connects with a rack manifold, and (2) the contracted configuration to the expanded configuration as the computing device disconnects from the rack manifold.

Abstract: An apparatus is provided for improving the cooling of a heat source. The apparatus includes a deflector mounted in a space between a first heat source and a second heat source. The deflector has a first face at a first angle that is greater than perpendicular from a first plane and a second face at a second angle that is less than perpendicular from a second plane. The apparatus further includes a plurality of vanes that extend from the first face of the deflector and are rotated inwardly with respect to the first face. When the first and second heat sources are immersed in a fluid and oriented with the second heat source above the first heat source, as fluid heated by the first heat source rises, the heated fluid is directed by the deflector away from the second plane and is directed by the plurality of vanes toward a center of the deflector.

Abstract: A latch assembly provides options for the retention within a rack of a chassis, and the retention within the chassis of a device. With the device in a device slot of the chassis, and the chassis installed in the rack, a first latch in a completely extended position prevents the device from being removed from the slot and prevents a latch tooth from being disengaged from the rack. With the first latch in an intermediate position, the latch tooth may be disengaged from the rack and the chassis removed from the rack, but the device may not be fully removed from the device slot. With the first latch in a retracted position the chassis may be removed from the rack and/or the device may be removed from the device slot.

Abstract: An apparatus is provided for completing a blind mate hydraulic connection. A device is equipped at the rear of the device with a shell holding a manifold connected internally to the device cooling system. Clearances between the shell and manifold allow the manifold to rotate in two axes to adapt to a misalignment between the manifold and a rack cooling system. The device is further provided with a cam-handle attached to the front that provides leverage against the rack for overcoming the connection forces of the blind mate. The manifold and cam-handle combine to facilitate disconnecting the device from the rack cooling system from the front of the rack and servicing the device.

Abstract: A cam latching device is provided for a computing system being installed in a rack. The cam latching device can include a cam and a locking mechanism. The cam includes a handle portion and an engagement portion. The cam includes a locking surface formed thereon. Rotation of the handle portion causes the engagement portion to rotate. The locking mechanism includes a push component and a lock. The push component abuts against a button disposed on a rail of the rack as the computing system translates along a longitudinal axis. When the push component slides against the button, the locking mechanism transitions from a locked configuration to an unlocked configuration. In the locked configuration, the lock abuts against the locking surface to prevent the rotation of the cam. In the unlocked configuration, the lock is retracted away from the locking surface so that the cam is rotatable.

Abstract: A cam system for a liquid cooled computing unit with blind-mate quick disconnects include a cam and a cam guide. The cam guide is operable to engage with the cam. The cam guide includes a bearing guide and a fixed guide. The cam engages first with the bearing guide then engages with the fixed guide to a latched configuration. When the cam engages with the cam guide and transitions to the latched configuration, the cam translates a chassis of the computing unit along a longitudinal axis to blind-mate the quick disconnects.
