Product Introduction

Product Description

Aluminium heat sink round are cost-effective solutions for the majority of electronic cooling applications. Extrusion profiles enable engineers to either select or start their design from a unique extrusion profile for the cooling solution. Applications can be for LED, IGBT, and IC devices or a wide range of other packages for electronics. Aluminium heat sink or aluminium extruded heat-sinks are mainly three types:

◆ Flat wide shape,or a fish bone-shaped comb-shaped;

◆ Round or oval-shaped;

◆ Branching shape.
