What does zipper fin heat sink entail?
A Zipper Fin Heat Sink, developed in-house, is a thermal management solution that mimics the human zipper, assembling a series of metal fins into slots in an elongated base.
Fins are made by stamping from sheets of aluminum or copper.
Next, they slide each fin into place within precision-slotted holders on the base.
As a result, the completed structure establishes a robust mechanical bond without necessitating one-piece extrusion.
High DXF fin densities can therefore be achieved by this design.
Also, since engineers can manipulate fin height, fin thickness and still have the fin spacing optimized to meet the demands of a given application.
Typical components include:
- Aluminum or copper base
- Precision zipper fins
- Mechanical locking structure
- Mounting features
Hence, zipper fin heat sinks have a very good cooling performance as well as flexible product support.
What is Zipper Fin Heat Sink?
Heat Transfer by conduction and convection in a Zipper Fin Heat Sink
Step 1 Electronic components transfer heart to the base.
So first, the base spreads thermal energy among every fin.
Then, the airflow takes away the heat of the fin surfaces.
As a result, the component temperature decreases quickly.
On the other hand, with high fin density, total cooling zone increases too.
Because of this, thermal resistance drops rapidly.
In addition, engineers often attach 【Zipper Fin】 structures and Heat Pipe structures to zipper fins.
And many high-performance cooling modules incorporate 【Vapor Chamber】 technology.
So thus even further cooling capacity increases.
Manufacturing Process of a Zipper Fin Heat Sink
Manufacturers have some steps in producing them accurately.
Material Selection
Manufacturers choose between aluminum or copper first.
This makes them guarantee very good thermal conductivity.
Fin Stamping
The next station uses stamping equipment to manufacture single cooling fins.
This process results in uniformly sized fins being produced by the manufacturers.
Base Machining
CNC machines carve the bottom of the heat sink into ultra-precise grooves.
Therefore, every fin fits securely.
Fin Assembly
These fins are loaded into the grooves one by one with the help of operators or automated systems.
This in turn keeps the mechanical moving structure intact,
Surface Treatment
Manufacturers commonly apply:
- Anodizing
- Nickel plating
- Sandblasting
- Anti-corrosion coatings
Consequently, durability improves significantly.
Final Inspection
Last but not last, the engineers check dimensions, fin alignment and overall thermal performance.
All of the products meet quality standards, therefore
Zipper Fin Heat Sink Materials
How to Select Materials For Efficient Cooling Systems
