Pin fin heat sinks are part of a performance-oriented technology. They generate low drop pressure and exceptional cooling power. The omnidirectional system allows air streams to enter the array of pins from all directions.
Pin fin heat sinks are a flexible approach. The parts can be modified to fit specific requirements of an application. Characteristics of pin fin heat sinks include:
Bonded Fin Heatsinks
When the box gets too small, or things get too hot, bonded fin heatsinks increase the surface area without an increase in volume. Thermal resistance is reduced by a third to a half. Bonded fin heatsinks provide cooling for forced convection with 100 W of power or more.
Augmented surface bonded fin heatsinks reduce the overall thermal resistance by 15 to 25 percent. The option increases the air flow turbulence at the same time that multiple, short air channels are substantially increasing heat removal.
There are many benefits for thermal design engineers who choose bonded fin heatsinks over conventionally extruded aluminum heatsinks. The tightly controlled assembly technique increased the fin count which allows the manufacturing process to be independent of the base extrusion.
The process removes the limitation of conventional fin extrusion ratios dictated by the extrusion dies' steel strength. Bonded fin heatsink parts offer the highest possible fin ratios. They can be 30 to one or greater.
