Classification: CPC F | IPC F

Claim 0:
1. A heat exchanger, comprising:
an enclosed cooling fluid channel comprising a heat transfer surface, the cooling fluid channel adapted to receive a flow of a liquid cooling fluid along a length of the cooling fluid channel;
an anchor extending across the cooling fluid channel in a direction perpendicular to the length of the cooling fluid channel and parallel to the heat transfer surface;
an active vortex generator affixed to the anchor and configured to extend in a direction parallel to the heat transfer surface; and
an actuator coupled to the anchor and configured to move the anchor along an oscillation path within the cooling fluid channel, wherein the oscillation path within the cooling fluid channel is perpendicular to the heat transfer surface and is closer to the heat transfer surface than a surface of the cooling fluid channel opposite to the heat transfer surface such that vortices generated by the active vortex generator are produced in a thermal boundary layer along the heat transfer surface.
