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.
