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-Thermal produces some standard sizes, and some of the sizes can be purchased with a bracket for easy mounting of a fan.
Configurable in a variety of ways, bonded fins are reliable, cost effective, and highly efficient thermal management solutions for high power and densely packaged applications, even in demanding shock and vibration environments. Bonded fin heat sinks are used when the required combination of large heat sink size, tall fins, and high fin density make simple extrusions impractical.
We offer these products in our standard catalogue and also custom fabricated to meet a customer's specific needs.
