Abstract
A heat sink 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.
Claims20
A heat sink comprising:
- a heat exchanger comprising a branched pattern of heat exchange elements, defining a plurality of concave regions configured for turbulent interaction with a flowable heat exchange medium;
- and
- a fan configured to induce the flow of the heat exchange medium and cause the turbulent interaction, wherein a peak acoustic frequency emission of the turbulent interaction of the flow of the heat exchange medium and respective ones of the plurality of concave regions is spread across an acoustic spectrum.
A heat sink comprising:
- a branched pattern of heat exchange elements, defining a plurality of external surfaces configured to induce a turbulent interaction from a convective flow of a flowable heat exchange fluid,
- wherein a peak acoustic frequency emission of the turbulent interaction is spread across an acoustic spectrum dependent on the branched pattern.
A heat sink comprising:
- a heat exchanger comprising a plurality of heat exchange elements organized in a branched pattern and being configured for turbulent interaction of a convective flow of a heat exchange medium with exterior surfaces of the plurality of heat exchange elements;
- and
- a device configured to induce the convective flow of the heat exchange medium with respect to the plurality of heat exchange elements;
- wherein the turbulent interaction of the convective flow of the heat exchange medium with the exterior surfaces of the plurality of heat exchange elements occurs substantially without narrowband resonance.
