Start the machine, engineer monitors the machine, inspects the semi-finished products to make sure it meets the data requirements.

 

 

Step3: Processing 

 

According to customer needs, process the semi-finished skiving fin heat sink. (CNC machining, Brush surface finish, Grinding)

 

 

Advantages of skivied fins heat sink

 

 

Low thermal resistance

Perfect conductivity between base and fins. Because skived fin heat sink is a whole profile without any connection point, which can give full play to the heat dissipation characteristics of the heat sink.

01

High density fin

Awind skived fin process can make the skived fin more thinner and denser, with higher heat transfer efficiency.

02

lower cost

Customized skiving fin heat sink does not need expensive tooling but can provides greater design flexibility. Instead, each skiving fin is cut separately using the same tool which allows for lower tooling costs.

03

Flexible Design

Compared with aluminum extrusion and other processes, skived fin heat sink is less limited in size and can be made wider, which can be used for heat transfer of machines with large power.

04

Polishing texture
Due to the polishing effect, this surface finish will provide a bright luster for the skiving fin heat sink.

Sandblasting texture
This surface texture will give the skiving fin heat sink a matte and uniform surface.

Brushed texture
Through this surface treatment, it is easy to see patterns of parallel lines. Through metal polishing, the scraped surface of skiving fin heat sink will receive a unidirectional satin finish treatment.

Machining texture
The machine operation of skiving fin heat sink will determine the appearance of the texture.

Transparent chromate coating
To coat the skiving fin heat sink using electrochemical technology, you will apply a chromate coating. The skiving fin heat sink will have a decorative surface finish. This will help maintain its conductivity after applying a chromate coating.

powder coating
The dry powder used in this process is thermoplastic polymer or thermosetting polymer. Before heating and curing, you will use electrostatic charges to apply dry powder. skiving fin heat sink will have a surface finish formed from this powder, which has the highest durability than ordinary coatings.

Chemical nickel plating
Similar to transparent chromate and anodic oxidation electrochemical processes, nickel electroplating does not require current. By electroless nickel plating, a uniform metal layer can be formed on the skiving fin heat sink.

Anodizing treatment
This is an electrochemical process that can produce corrosion resistance and durable surface finish.

Anodizing treatment

Increasing the fin area

Increasing the number or area of fins can improve the contact area with air, thereby enhancing the heat exchange effect.

Optimize fin shape

Choose appropriate fin shape and spacing, increase airflow channels, reduce airflow resistance, and improve heat dissipation efficiency.

Using thermal conductive materials

Choose materials with high thermal conductivity (such as aluminum or copper) to manufacture heat sinks and enhance thermal conductivity.

Improving airflow

By using fans or other airflow devices to increase airflow velocity, cooling efficiency can be improved. Consider using a variable speed fan to adjust the wind speed according to the cooling requirements.

Surface treatment

Treating the surface of fins (such as anodizing or coating) to increase heat radiation capacity or improve airflow adhesion.

Skiving fins heat sinks can dissipate heat to the maximum extent possible in a very limited space, as they have a very large surface area to volume ratio due to their high packaging density. Due to its superior heat dissipation performance and structural design, skiving fins heat sinks are widely used in situations that require efficient heat dissipation.

High Height Fins

The high fins can extend the heat dissipation area upwards, increasing the area in contact with the air, which is more conducive to heat dissipation.

Multiple fins and reasonable fin spacing

Having more fins results in a larger heat dissipation surface area, and a reasonable fin spacing can allow air to flow quickly and smoothly, thereby taking away more heat.

Processing the bottom of heat sink

The bottom of the heat sink is processed according to the requirements to make it closer to the heat source.

Inverter heat sink
Nowadays, the power density of high-power inverters is constantly increasing. The high temperature caused by high power density can have a serious impact on most electronic components, leading to electronic component failures and ultimately causing the entire inverter to malfunction.
For the heat dissipation design of high-power inverters, we have adopted a combination of large-sized skivied fins heat sinks welded with heat pipes.
The use of aluminum material skivied fins heat sinks, with high and dense fins, allows for sufficient extension of the heat dissipation surface area, which is more conducive to heat dissipation.
The bottom of the skivied fins heat sink is slotted with CNC and welded with several heat pipes. Heat pipes can transfer heat from the higher temperature end to the lower temperature end, thereby making the overall temperature of the heat sink more uniform and more conducive to heat dissipation.
