Patent Application Titled "Carbon-Metal Thermal Management Substrates" Published Online

August 28, 2014

By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors Jiang, Nan (Austin, TX); Yaniv, Zvi (Austin, TX), filed on September 20, 2012, was made available online on August 14, 2014.

The assignee for this patent application is Applied Nanotech Holdings, Inc.

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.

"FIG. 2 illustrates a graphite-aluminum based substrate fabricated with the use of nano-Cu paste.

"FIG. 3 illustrates a graphite-aluminum based substrate fabricated by a soldering approach."
