Brazed Fin

High Fin Density Heat Sinks provide increased efficiency for high power applications under forced convection by creating greater volumetric surface area and are classified into two types: High Aspect Ratio Extrusions and Fabricated Fin Assemblies. Although both types offer considerable performance gains over standard extrusions, Fabricated Fin Assemblies are constructed from a base and have independent fins, which allow greater aspect ratios1 than current extrusion processes. These heat sinks can be assembled using a variety of fin types such as stamped, folded, or zipper which are attached to a base using epoxy bonding, swaging, brazing, or soldering.
