Bonded Fin Heat Sinks

The resultant bonded swaged heatsinks are designed to meet very specific needs.

Bonded fin heat sinks. Reduces heat sink and overall system volume. 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. 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. Our wide range of high performance heat sink profiles with optimized geometries provide outstanding heat transfer performance.

All our r d heat sink cooling solution experts to help you. 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. Bonded fin heat sink.

Market leaders in power conversion rely on these profiles for cooling demanding applications like high power. Bonded fin heat sinks are an assembly of a grooved base with individual fins bonded into the grooves. Bonded fin our bonded swaged heatsinks are manufactured from either aluminum or copper metal sheets or by using an extrusion process. Bonded fins technique is a conventional high power large heat sink manufacturingtechnique.

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. Sns cooling technology offers bonded fin products with ratios as high as 40 1. Using either an epoxy or a solder braze process the fin is bonded to the base hence the name bonded fin. Our heat sink solution from various manufacturing process including.

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. Cnc machining extrusion bonded fin folded fin cold forged skiving stamping friction stir welding.
