Bonded Fin Heat Sinks Bonded Fin Heat SinksBonded Fin Heat Sinks Bonded fin heat sinks can provide significant cooling surface increase over conventional extrusions without increasing system volume. This increased surface area, thinner fins, higher conductivity fin material and fin heights are all benefits of this construction. Features Maximum thermal surface area Dense fin pitch versus other technologies Large fin heights are easily provided Fins attached typically by brazing, soldering or thermally conductive epoxy Minimal tooling required

• heat pipes available4, 6, 8 ,10 , 12 and 25 mm

Niagara Thermal Products and Thermshield have been making heat sinks for over 25 years for a broad range of markets. Together we are committed to providing our customers excellent value through world class thermal engineering and a global manufacturing footprint. The links below describe some of the basic heat sink constructions, however the final product is developed through the strong working relationship we have with our customers in solving the technical problem with any type or combination of technologies.

A majority of heat sink currently in production are made using finned aluminum extrusions. Aluminum is lightweight, has high thermal conductivity and is easily customized & machined to fit a wide variety of applications. Recent improvements in extrusion tooling and pressing processes allow far greater fin density, more cooling surface, than was available just a few years ago. Increased cooling surface with proper air flow reduces semiconductor junction temperatures, increase power output and increases system life.
