20150043167 | HEAT SINKS WITH INTERDIGITATED HEAT PIPES - A chip package includes adjacent integrated circuits on a circuit board, and separate heat sinks are thermally coupled to the integrated circuits. Because the integrated circuits are in close proximity, heat pipes in the separate heat sinks are interdigitated to prevent mechanical interference between the heat sinks. The amount of interdigitation depends on the separation between the integrated circuits and how the integrated circuits are arranged relative to an external fluid (such as flowing air). At the minimum, the heat pipes in fin regions of the heat sinks (which include fins for convective heat transfer to the external fluid) are interdigitated. However, the heat pipes may be interdigitated in pedestal regions of the heat sinks (which are thermally coupled to the integrated circuits) and/or in ramp regions of the heat sinks (in which vertical positions of the heat sinks change from the pedestal regions to the fin regions). | 02-12-2015 |

Moreover, the arms extend the vertical position of the winged heat sink away from a plane of the pedestal so that the convective fins extend downward back toward a circuit board on which the integrated circuit is mounted. These downward facing fins may match the topologies of components on the underlying circuit board. | 02-12-2015 |
