Extruded Heat Sink
Air-cooling is one of the most commonly use method of cooling adopted in Thermal Management of electronics products as it is free from any leakages. Click here to see complete range of extruded shape offered by SNS cooling technology. We can assist you in designing the most cost effective cooling solution for the most diverse application.
Due to limitation in fin pitch & fin height, the power dissipated using extrusion is limited & probably bonded fin, folded fin & liquid cooling is the answer to the solution.
Material Grade: SNS offers aluminum extrusion in 6063-T5 grade as it has higher thermal (Thermal conductivity: 209 W/m-K) compared to another most commonly used grade of aluminum which is 6061-T651 (Thermal conductivity: 167 W/m-K) normally available in plates form.
Surface finish: Following surface finishes are offered for products made out of extrusion.
