Repetitive thermal boundary layer disruption improves heat transfer performance. A better fluid mixing enables a more uniform temperature build-up of the coolant. The flow circulation regions could reduce the advection heat transfer efficiency. The vortices absorb the kinetic energy of the flow to sustain their angular momentum. Carefully tailored fin designs can provide reduced heat sink temperatures.
