  • Patent number: 10595440
    Abstract: An exemplary passive heat transfer apparatus is suited for transferring heat away from an electronic heat generating device to another environment. A gasket has many spaced-apart holes that are transverse to two major opposing surfaces of the gasket. A thermally conductive material is disposed within and fills the holes for conducting heat from one of the two major surfaces to the other major surface. The thermally conductive material is a nanocomposite material having nano-particles aligned substantially perpendicular to the two major opposing surfaces. The thermally conductive material as disposed in the holes has no interfacial boundaries that could adversely affect the transfer of heat.
