Abstract: A method of fabricating a vapor condenser is provided which includes a three-dimensional folded structure which defines, at least in part, a set of coolant-carrying channels and a set of vapor condensing channels, with the coolant-carrying channels being interleaved with and extending parallel to the vapor condensing channels. The folded structure includes a thermally conductive sheet with multiple folds in the sheet. One side of the sheet is a vapor condensing surface, and the opposite side of the sheet is a coolant-cooled surface, with at least a portion of the coolant-cooled surface defining the coolant-carrying channels, and being in contact with coolant within the coolant-carrying channels. The vapor condenser further includes, in one embodiment, a top plate, and first and second end manifolds which are coupled to opposite ends of the folded structure and in fluid communication with the coolant-carrying channels to facilitate flow of coolant through the coolant-carrying channels.

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assembly is operatively positioned within the chassis, and in extended state, when the air-moving assembly is withdrawn from the chassis.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coupled to the retractable cover and biases the retractable cover in the extended state when the air-moving assembly is withdrawn from the chassis, and compresses to allow transition of the retractable cover to the retracted state as the air-moving assembly is inserted into operative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: Energy efficient control of cooling system cooling of an electronic system is provided based, in part, on weighted cooling effectiveness of the components. The control includes automatically determining speed control settings for multiple adjustable cooling components of the cooling system. The automatically determining is based, at least in part, on weighted cooling effectiveness of the components of the cooling system, and the determining operates to limit power consumption of at least the cooling system, while ensuring that a target temperature associated with at least one of the cooling system or the electronic system is within a desired range by provisioning, based on the weighted cooling effectiveness, a desired target temperature change among the multiple adjustable cooling components of the cooling system. The provisioning includes provisioning applied power to the multiple adjustable cooling components via, at least in part, the determined control settings.

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.

Abstract: Tamper-proof electronic packages and fabrication methods are provided including an enclosure enclosing, at least in part, at least one electronic component within a secure volume, a two-phase dielectric fluid within the secure volume, and a tamper-respondent detector. The tamper-respondent detector monitors, at least in part, temperature and pressure of the two-phase dielectric fluid. In operation, the two-phase dielectric fluid deviates from an established saturation line of the two-phase dielectric fluid within the secure volume with an intrusion event into the secure volume, and the tamper-respondent detector detects, from the monitoring of the temperature and pressure of the two-phase dielectric fluid, the deviation from the established saturation line, and thereby occurrence of the intrusion event.

Abstract: Apparatuses and methods are provided for facilitating air-cooling of, for instance, one or more electronics racks within a data center. The apparatus includes an air-moving assembly and one or more flywheels. The air-moving assembly includes a shaft, one or more mechanical fans coupled to the shaft to rotate, at least in part, with the shaft, and a motor coupled to the shaft to rotatably drive the shaft. The flywheel(s) is sized and coupled to the shaft of the air-moving assembly to store rotational energy, and to facilitate, for a specified period of time, continued rotation of the shaft during interruption in power to the motor. In one implementation, the flywheel(s) is sized and coupled to the shaft to facilitate, for the specified time period, continued rotation of the shaft at a specified percentage, or greater, rotational speed of the shaft compared with shaft speed when rotatably driven by the motor.
