COMPOSITE CHASSIS FOR LOWERING SURFACE TEMPERATURE
First Claim
1. An information handling system (IHS) chassis, comprising:
- a chassis base defining an IHS housing that is operable to house a plurality of IHS components, wherein the chassis base includes an outer surface located opposite the chassis base from the IHS housing;
a first layer of the chassis base that provides the outer surface of the chassis base, wherein the first layer includes an first layer oxidized surface located opposite the first layer from the outer surface of the chassis base; and
a second layer of the chassis base that is located immediately adjacent the IHS housing, wherein the second layer includes a carbide-based composite material that is bonded with the first layer oxidized surface and that provides a thermal conductivity of less than 1 watt per meter-kelvin in a direction that is generally perpendicular to the outer surface of the chassis base, while providing a thermal conductivity of at least 100 W/mK in directions that are generally parallel to the outer surface of the chassis base.

Abstract
An IHS chassis defines an IHS housing that houses a plurality of IHS components. The IHS chassis includes an outer surface located opposite the IHS chassis from the IHS housing. A first layer of the IHS chassis provides the outer surface of the IHS chassis. The first layer includes a first layer oxidized surface located opposite the first layer from the outer surface of the chassis base. A second layer of the chassis base is located immediately adjacent the IHS housing. The second layer includes a carbide-based composite material that provides a thermal conductivity of less than 1 watt per meter-kelvin in a direction that is generally perpendicular to the outer surface of the IHS chassis, while providing a thermal conductivity of at least 100 W/mK in directions that are generally parallel to the outer surface of the IHS chassis.
