Skiving Heat Sink With High Fin Density

    For heat sink technology, there are two primary methods of creating the fins that dissipate heat, these methods are known as skiving and extruding. Both techniques are highly effective at cooling electronic components, but they have different advantages and disadvantages.

 

  Skiving is a method of creating fins by removing material from a block of metal, typically copper or aluminum, to create a series of thin fins. The fins are created by using a special cutting tool that progressively peel the sheets from the base, this process leaves a highly efficient heat sink with a large surface area, which allows for excellent thermal management.

 

  Extruding, on the other hand, creates a heat sink by pushing a billet of metal through a die that is shaped like the desired heat sink, this process creates a uniform fin shape that is typically rectangular or square, extruding is often less costly and quicker than skiving, but it may not provide the same level of thermal efficiency.

    

  For thermal efficiency, skiving heat sinks have better performance, due to skiving allows for a larger surface area with more fins, which can provide better heat dissipation. Additionally, the thin fins of a skiving heat sink create a larger contact area with the airflow, which further improve the cooling performance.

 

  For the extruded heat sinks, on the other hand, have a lower surface area and fewer fins, which makes them less efficient at cooling- performance ,but they still can be effective for some applications.

 

  One of the main advantages of extruded heat sinks is their lower cost, as the manufacturing process is simpler and uses less material, extruded heat sinks can often be produced at a lower cost than skived heat sinks. This can be an important factor in certain applications where cost is a major consideration.

 

  The manufacturing process of skiving and extruding is different, skiving requires a special cutting tool that progressively slices sheets from a solid block of metal, this process is  time-consuming and requires a skiving equipment. For extruding process, which is pushing a billet of metal through a die to form the designed extrusion shape, this process is quicker and requires less specialized equipment, which can make it more cost-efficient.

 

  Due to the fins of a skived heat sink are created by peel the sheets from a solid block, they can be shaped in a wide range of configurations, which allows for custom designs that can meet specific cooling requirements. But for extruded heat sinks, which are limited to the shapes and sizes that can be created using molds, although there are many different mold options available, they may not be able to meet the specific requirements of every application.

 

  Both skiving and extruded heat sinks are used in a variety of applications. Skived heat sinks are often used in high-performance applications where maximum thermal efficiency is required, such as in high-end LED or in industrial applications. Extruded heat sinks are more commonly used in lower-performance applications where cost is a major consideration. They can also be used in applications where space is limited, as their uniform shape can make them easier to fit into tight spaces.
