Bonded Fin Heat Sinks Brief

Bonded fin heat sinks are an assembly of a grooved base with individual fins bonded into the grooves. This type of heat sink fabrication allows for higher fin densities and fin aspect ratios which greatly improve thermal performance due to the increased surface area.

Bonded fin types can be constructed in a number of methods. Grooved bases can be extruded, die cast, or machined. Fins are either punched from coil stock or cut from thin plate stock. The fins and bases are joined together by epoxying, brazing or soldering
