Patent ID: 8453715

Claim:
A cooling system comprising: a heat sink comprising a base portion and a plurality of fins disposed on the base portion and extending vertically out therefrom, the fins being spaced to define a channel between each adjacent pair of fins in the plurality of fins; and at least one synthetic jet actuator attached to the heat sink, each of the at least one synthetic jet actuators comprising a plurality of orifices therein and being configured to generate and project a series of fluid vortices out from the plurality of orifices and toward a portion of the channels of the heat sink; wherein the plurality of fins comprises: a first set of fins positioned adjacent the plurality of orifices and so as to define channels that receive the fluid vortices projected out from the plurality of orifices, each fin in the first set of fins having a first three-dimensional shape, and a second set of fins not positioned adjacent the plurality of orifices to define channels that do not receive the fluid vortices projected out from the plurality of orifices, fin in the second set of fins having a second three-dimensional shape; wherein the second three-dimensional shape of each of the second set of fins is configured to promote the entraining of air into the heat sink in a radially inward direction and through the channels that do not receive the fluid vortices projected out from the plurality of orifices.
