Copper Skiving Fin Electronic Radiator With High Aspect Ratio

A copper skived custom heatsink uses special cutting tools and a controlled shaving technique to produce a heatsink from a single block of copper material.The typical result is a thin-finned heatsink, with a dense population of uniformly shaped and distributed fins.Skived heat sinks are manufactured by peeling fins from a bar of solid copper, using a sharp and accurately controlled blade tool. The tool slices a thin sheet of the material, lifts it up and bends it vertically to form the fin. The final heat sink can be machined using normal fabrication techniques, such as CNC machining. Skived heat sinks require minimal tooling cost, which makes it a cost effective solution. Skived heat sinks can also be customized with embedded heat pipes to further improve thermal performance.

Features and Benefits of copper skived fin heat sink

• Thin thickness of fins and high fin density
• Great heat dissipation performance in single solid heat sink type under forced convection
• No interface joint (or thermal resistance) between the fins and base
• Very high aspect ratio (up to 50)
• Minimal NRE cost
• Flexible prototype building and short lead time
• Heat pipes can be embeded to imrpove the thermal performance
• Passivation surface finish to extend the service life

Applications of Copper Skived Heat Sinks

Skived copper heat sinks offers maximum heat conduction and heat dissipation in applications with limited space and high levels of ventilation. They are a cost effective solution when considering the low tooling cost and the optimized thermal performance.

Copper skived fin heat sinks are commonly used in the following applications:

• Computers and electronic components
• Telecommunication equipment
• Industrial equipment and components
• Lighting lamps and household appliances industry
