SYSTEM AND METHOD FOR MAINTAINING EFFICIENCY OF A FRACTAL HEAT SINK

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.

主权项

1. A heatsink system comprising:
a base structure configured to interface with a heat source; a heat exchange device configured to receive heat from the base structure, and emit the received heat from a heat exchange surface of a plurality of heart exchange elements, into an external surrounding heat exchange medium, the heat exchange surface being subject to accumulation of particles; and at least one of:
a particle-dislodging device configured to mechanically disrupt an accumulation of particles on the plurality of heat exchange elements; anda particle degrading device configured to induce a chemical modification of an accumulation of particles on the plurality of heat exchange elements.
