    Abstract: An air-to-coolant heat exchanger for an electronics rack is provided, which includes first and second tube segments, one or more connector segments, and a plurality of thermally conductive fins attached to the tube segments. The first tube segment includes a first inner tube positioned within a first outer tube, defining a first inner coolant-carrying channel and first outer coolant-carrying channel, and the second tube segment has a second inner tube positioned within a second outer tube, defining a second inner coolant-carrying channel and second outer coolant-carrying channel. The connector segment(s) couples in fluid communication at least one of the first and second inner coolant-carrying channels, or the first and second outer coolant-carrying channels. The heat exchanger is coupled to separately receive a first coolant and a second coolant, with the first coolant passing through the inner channels, and the second coolant through the outer channels.

    Abstract: Thermoelectric-enhanced, rack-level cooling of airflow entering an electronics rack is provided by a cooling apparatus, which includes: an air-to-liquid heat exchanger; a coolant loop coupled to the heat exchanger, the coolant loop including a first loop portion and a second loop portion, where the heat exchanger exhausts heated coolant to the first loop portion and receives cooled coolant from the second loop portion. The cooling apparatus further includes a heat rejection unit and a thermoelectric heat pump(s). The heat rejection unit is coupled to the coolant loop between the first and second loop portions, and provides partially-cooled coolant to the second loop portion. The thermoelectric heat pump is disposed with the first and second loop portions coupled to opposite sides to transfer heat from the partially-cooled coolant within the second loop portion to provide the cooled coolant before entering the air-to-liquid heat exchanger.

    Abstract: Apparatuses and methods are provided for protectively covering an air inlet or outlet of an air-moving assembly. The apparatus includes a protective cover assembly, which includes a retractable cover and a spring-biasing mechanism. The retractable cover transitions between a retracted state, when the air-moving assembly is operatively positioned within the chassis, and in extended state, when the air-moving assembly is withdrawn from the chassis. In retracted state, the retractable cover is retracted away from the air inlet or outlet, and in extended state, the retractable cover covers, at least partially, the air inlet or outlet. The spring-biasing mechanism is coupled to the retractable cover and biases the retractable cover in the extended state when the air-moving assembly is withdrawn from the chassis, and compresses to allow transition of the retractable cover to the retracted state as the air-moving assembly is inserted into operative position within the chassis.

    Abstract: Systems and methods are provided for data center cooling by vaporizing fuel using data center waste heat. The systems include, for instance, an electricity-generating assembly, a liquid fuel storage, and a heat transfer system. The electricity-generating assembly generates electricity from a fuel vapor for supply to the data center. The liquid fuel storage is coupled to supply the fuel vapor, and the heat transfer system is associated with the data center and the liquid fuel storage. In an operational mode, the heat transfer system transfers the data center waste heat to the liquid fuel storage to facilitate vaporization of liquid fuel to produce the fuel vapor for supply to the electricity-generating assembly. The system may be implemented with the liquid fuel storage and heat transfer system being the primary fuel vapor source, or a back-up fuel vapor source.
