摘要： A heat sink comprising a heat exchange device having a large-scale morphology over a scale range and a small-scale texture over a scale range, wherein at least one of the large-scale morphology and the small scale texture has a fractal-like self-similarity over a scale range. The large-scale morphology and small-scale texture may be defined and implemented independently, or be provided with a transitional range. The large-scale morphology may be algorithmically optimized according to a set of geometrically constraints. The small-scale texture may be optimized according to aerodynamic parameters and constraints. The heat sink may be dynamically varying, and/or operated in conjunction with a dynamically varying heat transfer medium supply.

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 successive elements or regions having varying size scales. According to one embodiment, an accumulation of dust or particles on a surface of the heatsink is reduced by a removal mechanism. The mechanism can be thermal pyrolysis, vibration, blowing, etc. In the case of vibration, adverse effects on the system to be cooled may be minimized by an active or passive vibration suppression system.

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 successive elements or regions varying according to a fractal relationship. According to one embodiment, a noise spectrum due to fluid flow is wideband. According to another embodiment, surface boundary layers are disrupted to increase heat transfer. Flow-induced vortices may be generated at non-corresponding locations of the plurality of fractally varying heat exchange elements.

摘要： 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.
