A heat exchanger fin includes a plurality of vortex generator louvers spaced apart, such that there is a gap between adjacent louvers through which a fluid, such as air, flows. Each vortex generator louver is provided with one or more mini-vortex generators along an outer edge of the louver. The mini-vortex generators trigger vortices that flow across the vortex generator louvers.
