The round, aerodynamic pin design reduces resistance to surrounding airstreams that enter the pin array, while simultaneously increasing air turbulence. is a one-stop shop for all of. the air within the heat sink’s fins. The higher fin densities and fin aspect ratios provide a greater surface area, which greatly improves thermal performance. Overview of Bonded Fin Heat Sinks Market 2019. Bonded fin heat sinks are an assembly of a grooved base with individual fins bonded into the grooves. Heat sinks are made of metals like copper or aluminum alloy. The main advantage to this type of heat sink is it can be used for large applications, such as a DC-DC converter or battery charger. Bonded fin technique is a conventional high power heat sink manufacturing technique. Heat transfer to the air through use of a heat sink starts with conduction from the heat source through the source-sink interface.
