  • Graphite base for heat sink, method of making graphite base and heat sink
    Patent number: 7491421
    Abstract: A graphite base is made by: mixing nanometered graphite powder with a bonding agent to form a graphite mixture and then grinding the graphite mixture and processing the graphite mixture into a graphite mass with a high pressure by means of hot press, cold press and vibration, and then dipping the graphite mass in a liquid phase asphalt, and then baking the graphite mass to a dry state graphite block. The dry state graphite block is further coated with a layer of metal coating and bonded with metal radiation fins to form a heat sink.
    Type: Grant
