The benefits of push fins heatsinks include the following aspects:
1> Higher fin density (thinner fin thickness and smaller fin spacing)
The push pins heat sink has a higher density and increases the heat exchange area within a limited volume.
Other heat sink is limited by the mold and extrusion process, the fin thickness and fin spacing cannot be too small. And the skiving fins process is almost unrestricted, and you can also make a fins thickness and fins spacing of 0.05.
2> High height of heat sink fins
The height of the fins of the push fins heat sink can reach 120mm, or even higher in process theory, fully meeting the production needs of heat sinks in most application scenarios;
3> The fin of the shovel tooth heat sink can be made thinner and more precise
As mentioned in Article 1, thinner fins with smaller spacing can make the radiator lighter;
4> The bottom plate and fins are integrated, without additional thermal resistance increase, and the structure is more reliable
The shovel tooth heat sink is scooped up on the original material, so the heat dissipation efficiency is not damaged, can reach 100% of the original material profile's heat dissipation efficiency, and there is no risk of loosening or falling off, improving the reliability of machine operation.
Welding fins is prone to the phenomenon of virtual soldering increasing thermal resistance.
5> High compatibility of shovel tooth heat sink
The shovel tooth heatsink is integrally formed and has a high possibility of later processing. It can also be combined with processes such as buried copper pipes to improve heat dissipation performance.
Whether it is soft soldering or hard soldering, it can adapt to the corresponding temperature rise in the manufacturing process.
6> Suitable for mass production
The performance and efficiency of the skivied fins machine are constantly improving, and the material of the skivied fins is constantly improving, making it suitable for mass production.
7> Compatibility of materials
Common thermal conductive materials such as copper, aluminum, and series alloys can all be used for skiving fins. Moreover, there are currently cases of mass production of copper aluminum composite materials for skiving fins.
8> Diversified structural types
In addition to the common single sided fins, the skiving fins process can also produce double-sided fins, pipe four sided fins, circular fins, and irregular fins. The current technology can meet the structural design requirements of the vast majority of heat sinks.
9> Reduce mold investment and save development and mass production investment costs
Because there is no need for additional forming molds during the skiving fins process, for products of different sizes and structures, it is only necessary to replace materials and blades, and set a new skiving fins program, which can significantly reduce the sampling time and cost. The cost of mass production has also been correspondingly reduced.
