Abstract: Example implementations relate to a leak mitigation system for a cooling system in a computing infrastructure. The leak mitigation system may include tank that is pre-pressurized, a valve unit fluidly coupled to the tank and a cooling loop, and controller operatively coupled to the valve unit. The cooling loop comprises one or more tubes to facilitate a flow of a coolant to cool one or more computing devices. The controller may detect a leak of the coolant from the cooling loop, and in response to detection of the leak of the coolant, the controller may operate the valve unit to establish a fluid coupling between the tank and the cooling loop to transfer at least a portion of the coolant away from the cooling loop.

Abstract: In one implementation, a system for valve failure prediction includes a temperature engine to determine a temperature of a liquid exiting a cooling device, a flowrate engine to compare an actual flow rate of the liquid exiting the cooling device to a flow rate threshold, a prediction engine to determine when a valve of the cooling device is malfunctioning based on the comparison of the actual flow rate and the flow rate threshold, and a notification engine to notify a user when the valve of the cooling device is malfunctioning.

Abstract: A pump includes an armature, a rotor assembly, a liquid path connector and a member. The armature includes a ferromagnetic core, a winding and a through passageway. The rotor assembly is disposed in the passageway and includes an impeller to rotate to pump liquid through the passageway. The liquid path connector is connected to the armature to communicate the liquid with the passageway. The member contacts an outer surface of the armature and contacts an outer surface of the liquid path connector to transfer thermal energy from the armature to the liquid path connector.

Abstract: A device including a circuit component that dissipates heat and a cooling loop thermally coupled to the circuit component, is provided. The cooling loop includes an inlet port configured to receive a cooling fluid, a first axial pump disposed along a fluid flow channel and configured to move the cooling fluid axially through the fluid flow channel in the cooling loop at a specified flow rate, and an outlet port configured to transfer the cooling fluid out of the cooling loop, wherein the specified flow rate is adjusted according to one or more parameters.

Abstract: Examples herein relate to detecting a coolant leak. For example, a system includes a nanosensor coupled to an airflow channel in a server. The nanosensor provides a resistance measurement to a controller. The system includes the controller coupled to the nanosensor. The controller detects the coolant leak based on the resistance measurement from the nanosensor.

Abstract: An example method includes positioning a thermal bus bar into a bus bar support channel of a cooling wall, the cooling wall comprising a plurality of thermal bus bars. The positioning comprises removably connecting first portions of at least two dripless connectors coupled to a fluid flow path of the thermal bus bar to second portions of the dripless connectors coupled to coolant transport lines that receive and return coolant from a coolant source. The method further includes flowing coolant received from the coolant transport lines through the fluid flow path and returning the coolant to the coolant transport lines. The thermal bus bar is positioned while coolant provided by the coolant transport lines is flowing through other thermal bus bars of the cooling wall.
