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.

Liquid immersion cooling system

An apparatus and system provide coolant temperature data at the individual electronic device level, e.g., for a single server blade, using thermally conductive couplers positioned in-line with one or both of the fluid inlet and outlet tubes and temperature sensors in thermal contact with the couplers. Thus, provided with granular coolant temperature data at the device level, the cooling system, e.g., fan and/or pump speeds, may be controlled with the same level of granularity, thereby improving both temperature control and the conservation of energy.

Apparatus providing liquid temperature data from individual direct cold plate cooling units

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.

System for blind mate hydraulic connections

A method is provided for dynamically controlling fan speed of a computing system during boot and reboot. The method may include receiving an ambient temperature from a sensor by a controller. The method may also include controlling speed for one or more fans dynamically based upon the ambient temperature using a dynamic algorithm during boot and reboot of the computing system. The dynamic algorithm may include a function for the fan speed of the one or more fans based upon the ambient temperature.

Dynamic control for fan speed during system boot and reboot in hot and cold environments

A manifold system includes a supply manifold and a return manifold. The supply manifold delivers fluid to cold plates to cool processing units of a computing system. The return manifold receives the fluid from the cold plates. The supply manifold has supply fluid ports equidistantly spaced about the side surface of the supply manifold, and the return manifold has return fluid ports equidistantly spaced about the side surface of the return manifold.

Manifold for liquid cooled computing systems

A system is provided for collection, detection and containment of leaked liquid. The system may include a spout connected to a liquid cooling manifold for channeling liquid. The system may also include a collection tray positioned under the spout and configured to contain the liquid from the spout. The system may further include a leak detection rope having a first end coupled to the liquid cooling manifold, a middle portion extending along the spout, and a second end placed inside the collection tray for detection of liquid.

Liquid collection, detection and containment system for liquid cooled servers

An apparatus and system are provided for detecting coolant leaks from connections to rack-mounted devices and managing the leak by directing liquid away from sensitive electrical components. On each device, a pan is connected to liquid couplings found on the rear of the device. A sensor tape is attached to a vertical section of the rack, e.g., on the coolant supply lines or housing. The pan collects leakage from the couplings and directs the leakage to the sensor tape, which is connected to a control unit. Upon liquid contacting the sensor tape, the control unit signals the detection of a leak. To prevent false positives due to incidental leakage, e.g., mere drops leaked upon connection to the coolant system, the pan may include a texture in the pan surface that retains a small amount of fluid.
