Bonded Fin Heat SinksBonded Fin Heat SinksBonded Fin Heat SinksBonded 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.FeaturesMaximum thermal surface areaDense fin pitch versus other technologiesLarge fin heights are easily providedFins attached typically by brazing, soldering or thermally conductive epoxyMinimal tooling required

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.

Niagara Thermal Products provides full thermal and structural analysis of heat sink solutions across all markets. Heat Pipe heat sinks provide a unique improvement over simple extruded or other single component heat sinks. With the incorporation of heat pipes, this style heat sink is able to move energy away from where you must provide the cooling, but remotely eliminate it from the system. It also, enhances performance significantly with the use of two-phase cooling. At the core of every heat pipe is a fluid which is allowed to evaporate at the heat input site, and condense at the cooling site. The heat transfer potential of this well-known thermodynamic process is unmatched in typical conduction within aluminum or copper. This unique, cost optimized component provides a level of thermal performance unmatched in conventional heat sinks.

Our extensive heat transfer fin capabilities coupled with CNC, electrical discharge machining (EDM) and high and low temperature provide us exceptional flexibility in design and manufacture required to produce complex heat sinks for the most demanding applications.

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.
