Abstract: A device and system for dissipating heat includes a bent portion of pyrolytic graphite in which a-b planes at a center region of the bent portion follow a surface contour of the bent portion. A method for making a heat dissipating device includes bending a flat sheet of pyrolytic graphite such that a-b planes at a center region of a bent portion follow a surface contour of the bent portion.

Abstract: An apparatus for dissipating heat includes a plate or pipe made of a planar thermal conductive material, such as pyrolytic graphite. The apparatus may include fins attached to the plate or pipe, and the fins can be made of the same or different material as the plate or pipe.

Abstract: Embodiments of the present invention include methods of disposing a metallic coating layer comprising a metal in an amorphous and/or fine grain microstructure over at least a portion of a surface of a pyrolytic graphite substrate, the metal comprising Nickel, Iron, a Nickel-Iron Alloy, or any combination thereof, and the grains of the metal being of 1 nm to 10000 nm in size. Embodiments of the invention also encompass the coated pyrolytic graphite articles. The coated substrate exhibits a thermal conductivity not less than the uncoated substrate.
