Abstract: A method for implementing power capping in a velocity cooled (VC) mobile data center (MDC). A management information handling system (IHS) applies a power cap for all power consuming components of the VC MDC based, in part, on the detected velocity of the VC MDC. The detected velocity is compared to an outside air cooling threshold velocity. In response to the detected velocity being below the outside air cooling threshold velocity, a first power cap is selected, based on the detected velocity being below the outside air cooling threshold velocity. In response to the detected velocity being at or above the outside air cooling threshold velocity, a second, higher, power cap is selected, based in part on the detected velocity being at or above the outside air cooling threshold velocity. Power capping is implemented to conserve available onboard power for IT equipment processing, based on availability of ram air cooling.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components between rotationally coupled housing portions through a thermal spreader disposed between the housing portions, such as a sheet having one or more layers of graphite. A tensioning assembly engages the thermal sheet to manage excess material associated with varying rotational orientations of the housing portions.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a main housing portion through a graphite torsion spring formed from a graphite sheet by cutting arms to extend out of opposing corners of a central portion and rolling the central portion about a central axis. The graphite torsion spring passes thermal energy between the housing portions with the spring releasing tension as the housing portions rotate from a closed to an open position and the central axis disposed about a hinge pin that couples the housing portions to each other.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a main housing portion to a vapor chamber integrated in a lid housing portion that distributes the thermal energy across the lid housing portion. A hinge protrusion formed in the lid housing portion defines a cylindrical opening that accepts a hinge pin to rotationally couple the housing portions to each other. The cylindrical wall defines a barrier with the vapor chamber so that a thermal conduit passing from the main housing portion to the hinge pin transfers thermal energy from the hinge pin through the cylindrical wall to the vapor chamber.

Abstract: A portable information handling system transfers thermal energy associated with operation of processing components in a first housing portion to a thermal exchanger in a second housing portion through a hinge that rotationally couples the first and second housing portions. The hinge has first and second axles that each define a channel. Fluid heated at the first housing portion passes through the channel to the thermal exchanger where thermal energy is rejected from the system. In one embodiment, a second hinge having first and second axles that each define a channel provides a return path for the fluid from the second housing portion to the first housing portion.

Abstract: A portable information handling system transfers thermal energy associated with operation of a CPU from a main housing portion to a lid housing portion with thermal conduction through a hinge assembly that rotationally couples the main and lid housing portions to each other. For example, thermal conduits insert into a hinge body and transfer thermal energy across the hinge body through a thermally conductive interface, such as the hinge body itself, thermal grease disposed in the hinge body, a liquid that fills a cavity of the hinge body shared by the thermal conduits, and a vapor chamber integrated in the hinge body.

Abstract: A portable information handling system transfers thermal energy associated with operation of a CPU to a location distal the CPU with a vapor chamber thermally interfaced with the CPU. A pressure adapter interfaced with the vapor chamber selectively changes the pressure within the vapor chamber to adjust the saturation point of a liquid in the vapor chamber that manages thermal transfer efficiency. For example, a controller interfaced with the pressure adapter modifies thermal transfer characteristics of the vapor chamber to control thermal conditions at the information handling system, such as in response to a temperature sensed at a housing surface, a battery, a display or at other locations of the information handling system.

Abstract: A velocity cooled (VC) mobile data center (MDC) utilizes exhaust/residual heat to preheat cooling air. The MDC includes a volumetric container with heat generating information technology (IT) equipment positioned therein, having a minimum operating temperature. The MDC includes a ram air based cooling subsystem that provides a flow of outside cooling air to cool the IT equipment when the MDC is mobile. An engine of the transport vehicle connected to the container generates exhaust/residual heat during operation. The MDC includes an exhaust heat re-routing subsystem, fluidly coupled to the container, and which channels the exhaust heat from the transport vehicle engine towards the container to provide additional heating of ingested ram air to bring the ambient temperature of the IT equipment up to within the specific range of operating temperatures, above the minimum operating temperature. A flow control mechanism selectively opened or closed to direct the exhaust heat flow.

Abstract: A velocity cooled (VC) mobile data center (MDC) includes a volumetric container having an air intake opening providing an air intake path for exterior air to ingress into the container at a high velocity to provide a flow of cooling air that cools the heat generating IT equipment operating within the VC MDC while the MDC is mobile. An air intake damper is positioned within the air intake opening and can be selectively positioned between a fully opened position to a fully closed position. The VC MDC includes an air handling unit (AHU) configurable to operate in a standby mode or an active mode, ranging from providing minimal airflow to providing maximum airflow. The level of operation of the IT equipment and the amount of cooling provided by the AHU is controlled, based, in part, on a velocity of the VC MDC and resulting amount of cooling air being ingested.

Abstract: An information handling system (IHS) includes a base station that has a transmitter coil to generate a magnetic field for charging a portable power source of a battery-powered electronic device. A receiver coil magnetically receives power from the transmitter coil of the base station. A power control module connected to the portable power source and the receiver coil charges the portable power source with the received power. A flexible ferrite shield is positioned on a side of the receiver coil opposite to the transmitter coil to shield the IHS electronics. A pneumatic diaphragm is formed by a portion of the flexible ferrite shield that is positioned for oscillating movement into a center cavity of the receiver coil. A diaphragm actuator is attached to the pneumatic diagram and is responsive to a triggering signal to oscillate the pneumatic diaphragm to disperse thermal energy that is generated by the receiver coil.

Abstract: A dew point of air entering an information handling system is determined based on the temperature and humidity of the air. Also determined is a temperature of facility cooling water entering the information handling system. A condensation mitigation procedure is activated if a difference between the temperature of the facility cooling water and the dew point temperature is less than a first threshold value. The condensation mitigation procedure includes reducing a flow-rate of the facility cooling water to a liquid manifold using a valve. The liquid manifold is in thermally-conductive contact with a heat-generating component included at the information handling system.
