The skived Fin heat sink is a type of heat sink that is constructed from a single piece metal material. It gives a reduced thermal resistance since there is no joint connecting the base and the fins. Since it allows for a high fin density and offers a thin finned heat sink, Skived Fin heat sink provides highly optimized cooling capabilities.

Skived fin heat sink is made of a piece of base material (aluminum or copper) .Under the mechanical action, the tilting Angle of the tool is controlled by the customized tool and the program written, the  base material  is precisely cut from the top by a shovel-tooth tool, and folded back to a position perpendicular to the base, and repeated at a certain spacing to form fins. Skived Fin Process can make the Fins thinner and denser, increasing the radiator area per unit volume, thereby improving heat dissipation efficiency.

ü Excellent thermal conductivity

The raw material for Skived fin heat sink is generally copper or aluminum, with a high thermal conductivity. The Skived Fin heat sink is constructed from a single piece of metal material, so the heat dissipation efficiency is not damaged.Without the limitation of the aspect ratio in mold manufacturing, the Fin can be produced thinner, longer, more dense.

ü Diversified structural types

Single sided，double-faced，special-shaped and four sided for pipes Skived heat sinks can be made for your needs.The current technology can meet the structural design requirements of the vast majority of heat sinks.

ü High durability

The surface of the Skived heat sinks adopt a special treatment process, which improves its strength and corrosion resistance. At the same time, there are gaps between the teeth, making the surface of the radiator less prone to curling.

ü Light weighting

Compared to traditional heat sinks, a  Skived heat sink of the same quality can obtain a larger surface area, making the entire radiator lighter.

ü Fin design considerations:

  Overall consideration should be given to heat exchange area, wind speed, heat exchange efficiency, Fin sheets that are too thin are prone to deformation, while those that are too dense can affect heat dissipation.

ü Determine the size of the heat sink based on usage and heat dissipation needs. The internal flow channels of the radiator should be as simple as possible to ensure smooth flow of the cooling medium.

ü There is no need for additional forming molds during the tooth removal process, so for different product sizes and structures, only materials and blades need to be replaced, and a new tooth removal program needs to be set.

ü Choosing the Skived Fin Process to make samples can significantly shorten the sampling time and cost.

ü The Skived Fin heat sinks can be equipped with a heat pipe, which has significant economic benefits in high-power heat dissipation scenarios.
