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

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.

Leak detection and management system for rack cooling systems

A rack door is disclosed for mounting one or more power distribution units (PDUs) to the front of a server rack. An embodiment allows access to power cables when the rack door is open or closed. An embodiment provides power cable routing that allows power cables from one PDU to be connected or disconnected independently from other cables on that same PDU or on another PDU mounted to the rack door.
