  • Patent number: 10303227
    Abstract: Thermal energy exposed at the outer surface of an information handling system housing is managed by spreading the thermal energy across the housing X and Y axes while restricting heat transfer from the housing at the Z axis. For example, a graphene outer surface couples to an aerogel substrate strengthened by a carbon fiber laminate. The graphene spreads thermal energy that escapes through the housing across the housing outer surface to limit the impact of thermal energy at any particular location, such as proximate to the location of a processor.
