Fractal heat transfer device

摘要

A heatsink comprising a heat exchange device having a plurality of heat exchange elements each having a surface boundary with respect to a heat transfer fluid, having a fractal variation therebetween, wherein the heat transfer fluid is induced to flow with respect to the plurality of fractally varying heat exchange elements such that flow-induced vortices are generated at non-corresponding locations of the plurality of fractally varying heat exchange elements, resulting in a reduced resonance as compared to a corresponding heat exchange device having a plurality of heat exchange elements that produce flow-induced vortices at corresponding locations on the plurality of heat exchange elements.

主权项

1. A heatsink comprising:
a heat exchange device having a plurality of heat exchange elements in a branched configuration having at least three levels of asymmetrical branching, having a fractal variation between respective branches, each heat exchange element having an asymmetric external heat exchange surface configured to transfer heat to a heat exchange medium outside of the heat exchange device; a forced convection device configured to induce a flow of an gaseous heat exchange medium outside of the heat exchange device, wherein the induced flow is associated with acoustic emissions from an interaction of the flowing heat exchange medium with the heat exchange device; and a flat base configured to interface the heat exchange device with a heat source.
