  • Flexible Graphite Thermal Management Devices
    Publication number: 20090032227
    Abstract: The invention provides to thermal management devices constructed from flexible graphite. In one embodiment, the thermal management device includes a wick structure inside a shell. In certain preferred embodiments, the wick structure is composed of a mass of expanded graphite. In a another embodiment, the shell of the device includes flexible graphite and an optional wick structure. In certain preferred embodiments, the flexible graphite shell is fluid impermeable. The invention further includes methods of making the aforementioned thermal management devices.

  • Heat sink made from longer and shorter graphite sheets
    Patent number: 6771502
    Abstract: A heat sink apparatus is constructed from alternating longer and shorter sheets of graphite material sandwiched together such that the longer sheets extend beyond the shorter sheets to define fins. The directions of higher thermal conductivity of the anisotropic graphite material are oriented in the plane of the sheet. The longer and shorter sheets have base ends aligned together to define a generally planar base surface for engaging an electronic device to be cooled.
