The long strips of plate are cut into relatively straight sheets at a certain angle using a special tool through mechanical action. Repeated cutting forms a uniformly ordered gap heat dissipation fin structure, which is then processed into a radiator through subsequent cutting, machining, surface treatment and other methods.

Shovel tooth principle
Design reference:
The shovel tooth technology can process a variety of materials: AL1060, Al6061, Al6063, Cu1100, Cu1020.
Application status:
The skived tooth process can obtain heat dissipation teeth with higher teeth and smaller gaps, thereby obtaining a larger heat dissipation area to improve the heat dissipation effect. The heat dissipation teeth and the base plate are integrally processed and formed without interface thermal resistance. With its excellent heat dissipation capacity, the skived tooth heat sink has become a widely used solution in the field of high-power air cooling and server liquid cooling modules.
Vansim’s years of experience in shovel tooth processing provide your products with stable quality skived heat sink output.
High-density fins of copper skived heat sink for PC water block
The bottom of the micro-channel cold plate has many extremely fine narrow water channels, which greatly increases the contact area between the bottom and the water coolant, forcing the water coolant to pass through the dense water channels at high speed and generate large turbulence, thereby efficiently absorbing heat. It is widely used in CPU cold plates.
The ultra-thin microchannel structure of the high-density copper skived heat sink constructs a multi-layer functional composite microstructure, which improves the bonding accuracy and strength while effectively improving the thermal conductivity of the bonding layer.
With the continuous expansion of the scale and capacity of data centers, integrated CPU packaging and cooling technologies represented by micro-channel flow tubes and spray jets have the advantages of strong heat transfer capacity, compact structure, good adaptability, controllable cost and low energy consumption. It is expected to become an effective way to solve the heat dissipation of high heat flux density server CPUs in the future. High-density skived heat sinks are the most commonly used and cost-effective cold plates to promote the development of micro-channel water cooling.

FSW Machining assisst the skived fin heat sink structure limited project
Due to the process characteristics of the skived heat sink, all the fin gap is the same. If the heat dissipation design needs to add thicker columns or fins in the middle of the teeth, the skived process itself cannot do it. So what method can be used to make the heat dissipation design realize production?
We use CNC processing to clear the position where the column needs to be added, and then on this basis, FSW is used to make the thick column and the skived heat sink become one, and finally realize the production of the overall heat dissipation design.

Skived heat sink is an efficient heat dissipation solution, especially suitable for high-power equipment such as plant lights. Skived heat sink uses high-precision cutting technology to cut a whole piece of aluminum or copper into fins with standard spacing. This design greatly increases the heat dissipation area and improves the heat dissipation efficiency.
The application of Skived heat sink in plant lights is mainly reflected in its efficient heat dissipation performance. Plant lights usually need to be used continuously for a long time and have high requirements for heat dissipation. Skived heat sink can effectively reduce the temperature of LED light source, extend service life and improve light efficiency by increasing the heat dissipation area and optimizing the heat conduction path.
Air-cooled and water-cooled hybrid radiators use a hybrid air-water design to provide better heat dissipation and user experience. This combined radiator design may include the use of a water cooling system in key heat source areas and an air cooling design in other areas. This can take into account both efficient heat dissipation and lower noise levels while avoiding the limitations of a single heat dissipation method. Different soldering or friction welding processes can be used to combine the heat sink and the water cooling plate to meet the design of the heat dissipation structure.
