    Abstract: A circuit card assembly includes a circuit card, a plurality of components disposed on a first surface of the circuit card in a shadow arrangement, and a plurality of air-cooled heat sink structures disposed on each of the components. Each of the plurality of heat sink structures comprises a plurality of impedance zones arranged in series substantially perpendicular to the airflow path, where the plurality of impedance zones comprise a first impedance zone having a first air impedance, and a second impedance zone having a second air impedance less than the first air impedance. Further, the plurality of zones in the plurality of heat sink structures are aligned so that the first impedance zone in one of the plurality of heat sink structures does not overlap with the first impedance zone in another of the plurality of heat sink structures, relative to the airflow path.

    Abstract: A computing device has a fan housing that includes a dual rotor fan with a first rotor and a second rotor. The computing device also includes a controller communicatively coupled to the dual rotor fan. The controller is operable to detect a failure associated with the first rotor. In response to detecting the failure, the controller is operable to drive the second rotor at a higher speed than a fan-speed at which the second rotor was being driven before the failure.

    Abstract: A computing device comprises a housing, a heat-generating electronic component, at least one additional electronic component, and a liquid cooling module. The heat-generating component, the at least one additional electronic component, and the liquid cooling module are all positioned inside the housing. The liquid cooling module is configured to cool the heat-generating electronic component, and includes at least one movable radiator. The at least one movable radiator is configured to move between a first position and a second position. When the at least one movable radiator is in the first position, the at least one movable radiator blocks access to the at least one additional electronic component within the housing. When the at least one movable radiator is in the second position, the at least one movable radiator allows access to the at least one additional electronic component within the housing.

    Abstract: A method and system controls cooling system leaks in a rack. The method includes monitoring leak detection sensors positioned at computer systems and below sections of a liquid conveyance system. In response to determining if a signal was received from one of the leak detection sensors that is indicative of a leak, the leak detection sensor and the corresponding one of the plurality of computer systems associated the received signal is determined. Power is disconnected to the corresponding one of the computer systems and a signal is transmitted to implement moving first and second valves from open to closed positions. The first valve is positioned within the liquid conveyance system between a hot rack manifold and a thermal contact structure associated with the computer system associated with the received signal. The second valve is positioned within the liquid conveyance system between a cool rack manifold and the thermal contact structure.

    Abstract: A closed-loop liquid cooling system includes a liquid coolant conduit, a cold plate, a pump and a heat exchanger. The liquid coolant conduit is in proximity to a heat-generating electrical component. The liquid coolant conduit allows circulation of a liquid coolant to extract heat therefrom. The liquid coolant conduit includes an inner portion that surrounds and contains the liquid coolant, and an outer portion configured to prevent or inhibit leakage of the liquid coolant from the inner portion and also detect any leakage from the inner portion. The cold plate is in thermal communication with the liquid coolant. The pump is configured to transport the liquid coolant in the liquid coolant conduit. The heat exchanger is coupled to the liquid coolant conduit to extract heat therefrom.
