Claim:
1. An integrated heat removal device comprising a selectively patterned graphite sheet material formed into a three-dimensional structure, wherein said selectively patterned graphite sheet material is patterned on at least one surface with an array of flattened protrusions in a first region of said graphite sheet material to increase a through-plane thermal conductivity of said graphite sheet material in said first region relative to a through-plane thermal conductivity in another region of said graphite sheet material, wherein said at least one surface is substantially flat in said first region, and a proportion of graphite flakes of said first region that are oriented in a through-plane direction in the first region is greater than a proportion of graphite flakes in another region that are oriented in the through-plane direction in the another region.
