Folded fin heat sinks

Folded fin heat sinks are created by bending a piece of aluminum sheeting in a fan or fin-like structure. This creates heat sinks that have higher aspect ratios and thinner fins than those that can be created by extruded aluminum heatsinks.

Product Introduction

Folded fin heat sinks are manufactured by bending aluminum or copper sheets into a variety of fin shapes which are then bonded to a separate base.

1. Lightweight heat fins
2. Reduced material costs
3. Reduce assembly weight
4. Minimize material thickness.
5. Reduce the center spacing of the fins, thereby increasing the number of fins in the width of the unit.
6. Fin height can reach 51 mm (2.0")
7. Minimize the thickness of the base plate.
8. The folding fin modules can be installed on mechanical heat sinks with thermal conductive epoxy resin, brazing, welding or similar metallurgical bonding.
