Bonded Fin Heat Sinks

Using either an epoxy or a solder braze process the fin is bonded to the base hence the name bonded fin.

Bonded fin heat sinks.

Market leaders in power conversion rely on these profiles for cooling demanding applications like high power. Reduces heat sink and overall system volume. 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 fins technique is a conventional high power large heat sink manufacturingtechnique.

Bonded fin heat sinks overcome some of the limitations of extruded aluminum heat sinks by allowing much taller fin heights and denser fin spacing. 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 fin our bonded swaged heatsinks are manufactured from either aluminum or copper metal sheets or by using an extrusion process. Bonded fin heat sink.

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 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. 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.

The resultant bonded swaged heatsinks are designed to meet very specific needs. Bonded fin heat sinks are an assembly of a grooved base with individual fins bonded into the grooves. 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. Sns cooling technology offers bonded fin products with ratios as high as 40 1.
