Abstract: A method for cooling IT equipment of a velocity cooled (VC) mobile data center (MDC) includes: determining if a velocity of the VC MDC is above a minimum threshold velocity that enables ram air cooling of IT equipment within the VC MDC; and in response to the velocity not being above the minimum threshold velocity, activating a secondary cooling source to provide a flow of cooling air across the IT equipment within the VC MDC, the flow of cooling air supplementing the ram air cooling.

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 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 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 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 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.

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.
