Reporters obtained the following quote from the background information supplied by the inventors: "Thermal management materials with high thermal conductivity, high thermal diffusivity, machineability, low coefficient of thermal expansion (CTE) at low cost are desirable. For example, carbon based materials, such as graphite and graphene, typically have a number of excellent properties including high thermal conductivity, high thermal diffusivity, low CTE, and light-weight, which are highly desired for power electronics applications as heat transfer substrates. However, graphitic materials have relatively low mechanical strength, which limits their applications."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Embodiments disclosed herein combine a carbon plate, such as, but not limited to a graphite plate, and a metal plate, such as, but not limited to an aluminum plate, together to form an architecture of a graphite-aluminum based hybrid substrate. This kind of hybrid substrate exhibits super thermal properties of graphite and, meanwhile, possesses a sufficient mechanical robustness due to assembling the substrate with a robust metal plate.
"The metal plate material may include a number of different types of materials. And the carbon plates may include graphite plates, and carbon/metal composite plates. An embodiment of this invention is to use aluminum and graphitic materials.
