Bonded Fin Heat Sinks

Our heat sink solution from various manufacturing process including.

Bonded fin heat sinks.

To satisfy different functional requirements from our customers we are making a big range of heat sinks products for our clients on base of different heat sink solution. Bonded brazed fin heat sink assemblies fins are epoxied soldered or brazed into an extruded or cast base in order to achieve a higher fin aspect ratio and fin density vastly improving thermal performance. Bonded fins technique is a conventional high power large heat sink manufacturingtechnique. Increases the cooling surface area by 2 to 3 times higher aspect ratio of fins dissipates more heat than conventional heat sinks with same footprint.

This type of heat sink fabrication allows for higher fin densities and fin aspect ratios than what is manufacturable with extrusion methodologies greatly improving thermal performance as compared to extruded heat sinks due to increased surface area. The resultant bonded swaged heatsinks are designed to meet very specific needs. Bonded fin heat sinks overcome some of the limitations of extruded aluminum heat sinks by allowing much taller fin heights and denser fin spacing. Reduces heat sink and overall system volume.

Sns cooling technology offers bonded fin products with ratios as high as 40 1. Our wide range of high performance heat sink profiles with optimized geometries provide outstanding heat transfer performance. Bonded fin heat sink.

They also make it possible to use other metals such as copper which have greater thermal conductivity but are not as readily extruded as aluminum. Bonded fin heat sinks in very demanding power applications where significant heat is generated in a small volume methode s bonded fin designs can meet your packaging needs by increasing the heat sink surface area without increasing volume reducing thermal resistance by fifty to sixty six percent. Bonded fin heat sinks are normally used is forced air circulation environment as there is no limitation on fin height to fin space ratio. Market leaders in power conversion rely on these profiles for cooling demanding applications like high power.

Bonded fin heat sinkmay have the bad phenomenon of loose heat sink fins especially with thick heat sink fins which will loose or even fall off at a higher rate. Using either an epoxy or a solder braze process the fin is bonded to the base hence the name bonded fin.
