Bonded Fin Heat Sinks: Wakefield-Vette

Bonded fins are a good high power solution for either natural or forced convection. Individual straight fins are cut and bonded into a grooved base plate. The fins are usually thicker than you would find on a zipper/skived or folded fin, so they have the ability to be more efficient, even at tall heights. Aluminum and copper fins can be combined on the same heat sink to provide improved performance without all of the weight gain. If weight is especially important, graphite fins can also be used, but they are more delicate so extra care must be taken. Wakefield-Vette produces some standard sizes, and some of the sizes can be purchased with a bracket for easy mounting of a fan.
