Folded Fin Heat Sinks

Heat sinks with folded fins offer many advantages: they maximize surface area while minimizing the volume of space occupied, offering optimal thermal performance.

Folded fins are available in a wide variety of materials and various fin densities. Folded fins can be attached to their base material with either thermally-conductive epoxy or by using dip-brazing technology to reduce the thermal resistance and to improve mechanical integrity.
