Abstract:
1. An active cooling assembly comprising: a fin configured to enable convective heat transfer to an airflow passing over the fin, wherein a boundary layer accumulates between the fin and the airflow, and wherein the boundary layer includes a region of heated air adjacent to a side of the fin; a blade configured to oscillate proximate to the fin to shear the boundary layer that accumulates between the fin and the airflow, wherein the region of heated air is sheared from the side of the fin, so that the impedance attributable to the boundary layer of the convective heat transfer from the fin to the airflow is reduced; and a swing arm coupled to the blade, wherein the swing arm oscillates with a translatory motion to cause the oscillation of the blade, and further wherein the oscillation of the blade translationaly displaces an entirety of the blade.
