摘要: A method, apparatus, and article of manufacture for improving the thermal efficiency for heat transfer from an electronic device using a vortex heatsink arrangement. The apparatus comprises a fin array having a plurality of fins and having a variable fin density, the fin array including a first fin array region proximate to and in thermal contact with the heat dissipating device; a second fin array region distant from the heat dissipating device. The first fin region includes a first fin density and the second fin region includes a second fin density less than the first fin density.

摘要: A heat transfer device wherein a vapor chamber is combined with a pin structure that allows the highly conductive cooling vapors to flow within the pins of a pin array maximizing the efficiency of both components of the heat sink into one unit is disclosed. In one embodiment the heat transfer device comprises a thermally conductive chamber having a first thermally conductive chamber portion having a base thermally coupleable to a heat dissipating device; a second thermally conductive chamber portion having a plurality of hollow protrusions extending away from and in fluid communication with the first thermally conductive chamber portion wherein the thermally conductive chamber comprises a fluid vaporizable when in thermal communication with the heat dissipating device and condensable when in thermal communication with the hollow protrusions.
