1. A heatsink, comprising:
an interface surface configured to transfer heat with respect to a heat source;
a heat exchange device configured to receive heat from the interface surface, and emit the received heat into an external surrounding heat transfer medium, wherein the heat exchange surface comprises heat exchange elements having distinct resonant frequencies, wherein at each resonant frequency a subset of the branched heat exchange elements selectively experience resonant vibrations; and
a vibration inducing element configured to:
concurrently excite resonant vibrations in a first subset of the heat exchange elements while avoiding exciting resonant vibrations in a second subset of the heat exchange elements, and
concurrently excite resonant vibrations in the second subset of the heat exchange elements while avoiding exciting resonant vibrations in the first subset of the heat exchange elements.
