Heat pipe is a type of heat transfer element, with a heat transfer efficiency that can reach several tens of times that of metal. It is composed of three main components: a sealed shell, working fluid, and capillary structure. The working fluid absorbs heat and vaporizes from the higher temperature side, while the saturated gas releases heat and condenses towards the lower temperature side. The working fluid changes phase within the application temperature range, and the casing keeps the working fluid of the heat pipe vacuum sealed to achieve continuous heat transfer for decades.

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 The appearance of the heat sink should consider aesthetics and space utilization efficiency.

ü The internal flow channels of the heat sink should be as simple as possible to ensure smooth flow of the cooling medium.

ü Design the shape and size of the heat sink according to actual needs to increase the heat transfer area.

ü A reasonable support structure should be designed at the bottom of the heat sink to improve its stability and structural strength.

Extrusion molding is the process of applying external force to a metal ingot stored in a container (extrusion cylinder), causing it to flow out of a specific mold hole, in order to obtain the desired cross-sectional shape and size of the profile.

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 Good thermal conductivity

Six series aluminum profiles have good thermal conductivity, with a thermal conductivity coefficient between 120-165 W/(m · K); Integrated molding, with fins that do not require additional welding processing and no additional thermal resistance; The structure can be flexibly designed to improve the heat dissipation performance of the radiator.

ü High durability

The aluminum extruded heat sink is made of high-purity aluminum material and has undergone processes such as anodizing treatment on the surface, which can effectively prevent oxidation corrosion and loss, and has a long service life.

ü Lightweight

Aluminum extruded heat sink is lightweight and compact, making it more suitable for lightweight electronic products and mechanical equipment.

The heat transfer performance of heat pipes is indeed very powerful, but to better play its role, it still needs to rely on the precise matching of the basic modules, fins, and other components.

ü Heat pipe selection: Heat pipes with different capillary structures have certain differences in heat transfer performance. In practical applications, forming processes such as bending and flattening need to be carried out to meet the heat dissipation needs of different heat sources. In addition, the diameter, length, and assembly direction of heat pipes can also affect their heat transfer performance.

ü Heat sink production and assembly: usually paired with heat pipes, stamped and toothed heat sinks are used. The thickness, length, spacing, arrangement of heat sinks, connection process between Fin and heat pipes, penetration of Fin, reflow soldering, etc. all affect the overall heat dissipation performance.

ü Module welding: The substrate, heat pipe, and heat sink are finally combined by welding. The flatness of the substrate, the connection between Fin sheets and the substrate and heat pipe, and the welding between heat pipes and substrate will all generate additional thermal resistance.

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 High power heat dissipation requirements, ideal choice for limited space, low noise, and environmentally friendly scenarios.

ü The engineering decision for the best solution for heat sinks generally depends on cost and performance. Heat pipe module heat sinks can be assembled and welded from heat pipes of different structures, Fin sheets of different processes, and substrates of different materials. Therefore, under the constraints of different application scenarios and working conditions, the cost range of a single heat dissipation module is very wide.
