  • Graphite sheet and heat transfer structure using same
    Patent number: 8720537
    Abstract: A graphite sheet preventing leakage of a heat radiating member when a fluid heat radiating member such as grease is used and improving heat radiation performance is provided. A graphite sheet includes a first main surface and a second main surface opposite to the first main surface and has a large anisotropic thermal conductivity in a main surface direction. The graphite sheet includes a first concave portion provided on the first main surface and having a first bottom surface, a second concave portion provided on the second main surface and having a second bottom surface, a thin film portion formed in a region in which the first bottom surface and the second bottom surface are overlapped with each other, and a connecting hole penetrating the thin film portion and allowing the first concave portion and the second concave portion to communicate with each other.
    Type: Grant

    Date of Patent: May 13, 2014
    Assignee: Panasonic Corporation
    Inventors: Kazuhiko Kubo, Yuichi Sato, Norihiro Kawamura, Masashi Funaba
  • Graphite complex and manufacturing method thereof
    Patent number: 8673446
    Abstract: A graphite complex has a pyrolytic graphite sheet and a graphite layer. The pyrolytic graphite sheet is made by firing a polymer film. The graphite layer contains graphite powder as the main ingredient and is directly joined to the pyrolytic graphite sheet.
