ABSTRACT:
The present invention provides thermal devices, materials and methods for use in transferring heat from heat sources. One embodiment comprises a thermal transfer body that has first and second end portions and includes a thermally anisotropic material that conducts more thermal energy in a longitudinal direction than in a direction transverse thereto, wherein at least one of the first and second end portions includes a projection having a surface area oriented obliquely to the longitudinal direction. Multiple projections may be provided of various geometries, such as pyramids, cones, triangular prismoids and domes. The thermally anisotropic material may include an ensemble of longitudinally thermally conductive fibers, such as carbon fibers derived from precursors such as petroleum or coal pitch, which may be embedded in a support matrix of various materials.
