1. A heatsink configured to transfer heat from a heat source to a surrounding heat exchange medium, comprising:
an interface, configured to receive heat into a heat transmissive body from the heat source;
the heat transmissive body receiving heat from the interface;
the surrounding heat exchange medium; and
a plurality of non-uniform heatsink surfaces extending from the heat transmissive body into the surrounding heat exchange medium, each of the plurality of non-uniform heatsink surfaces having localized geometric features having a branched fractal geometry relationship with self-similar features having differences in scale across the plurality of non-uniform heatsink surfaces defined by manufactured localized geometric features corresponding to at least three iterations of a fractal generative algorithm, configured to:
interact with a forced flow of the surrounding heat exchange medium to create distinct regions of separated flow of the surrounding heat exchange medium; and
generate self-sustaining oscillations of the surrounding heat exchange medium over a range of acoustic frequencies of the surrounding heat exchange medium dependent on the forced flow.
