摘要:
Graphite films are provided with a metal coating of at most 100 nm thick and are produced, for example by a continuous vapor deposition process on graphite film. In spite of the small thickness of the metal layer, the graphite films can be connected to one another or to other components of metal or metal-coated materials by soldering. Furthermore, the thin metal coating protects the surface of the graphite film against particles breaking out or peeling or flaking off.
摘要:
A method for applying a thin coating to a flat side (front side) and edge surfaces of a two-dimensional formation of graphite foil, includes applying the coating material to the flat side (front side) to be coated by electrostatic powder spraying followed by a sintering cycle or melting cycle. During the spraying, the two-dimensional formation is electrically contacted on a limited area virtually in the middle of its rear side, facing away from the spraying direction, on a limited area at a distance of at least 5 mm from the edges. A method for heat dissipation in electronic equipment, is also provided.

摘要:
The invention comprises, in one form thereof, a continuous processing apparatus for high temperature thermal treatment of granular materials. The apparatus includes a vertical conveyor means with an internal feed mechanism for transporting granular feedstock upward, an external export means for taking reacted product downward wherein said internal feed heats said granular feedstock by absorbing heat from the product flowing downward through said export means, and a heating means disposed around a top portion of said vertical conveyor means and said external export means.
