Skiving fin heat sink

Skiving fin is the process of relieving Al teeth. The profile is processed into a specific model, such as radiator, etc. with the skiving fin machine tool, the finished product is the skiving fin heat sink.

The skiving fin heat sink is a kind of gap structure with the same sequence formed by cutting the material out of a certain angle by mechanical action of the strip profile (aluminum and copper). It is used to solve the heat dissipation of high-power devices under the condition of air cooling and heat dissipation, and its heat dissipation efficiency can be increased by 8-15% compared with the other heat sink.

With the large-scale application, our skiving fin radiator technology are more mature, the level of automation is gradually improved, our cost and reliability advantages are remarkable. It is used in UPS, base station, charging pile, frequency converter, controller, wind power converter, SVG, LED lamp.

Key Applications

1.LED lighting
High-power LED street lights, factory lighting, stage lighting, and plant growth lights. Extruded heat sinks effectively manage the high heat generated by LED chips, extending the life of the lamp and maintaining stable light efficiency.
2.Power Electronics
In high-power density applications such as server power supplies, communication power modules, UPS (uninterruptible power supplies), industrial frequency converters, electric vehicle charging stations, and photovoltaic inverters, extruded heat sinks ensure that power semiconductor devices (such as IGBTs and MOSFETs) operate within a safe temperature range, preventing overheating and failure.
3.Industrial control and automation
Industrial PCs, programmable logic controllers (PLCs), servo drives, and robot controllers. In harsh industrial environments, extruded heat sinks provide reliable heat dissipation for sensitive electronic components, ensuring long-term stable operation of the equipment.
4.Telecommunications
5G base stations, routers, network switches, and data center servers. As data transmission rates increase, the heat generated by communication equipment increases dramatically. Extruded heat sinks provide an efficient passive cooling solution to reduce operating costs.
5.Consumer Electronics
High-performance desktop CPU/GPU cooling, game consoles, home theater systems, and large-screen TVs. In consumer electronics products that pursue extreme performance and compact design, customized extruded heat sinks can optimize heat dissipation efficiency and enhance user experience.
6.New Energy Vehicles
Power battery management system (BMS), motor controller, and onboard charger. New energy vehicles have extremely high heat dissipation requirements. Extruded heat sinks are key components that ensure stable operation of the power system under various driving conditions.
