The "Offset SS Type" is a heat sink that improves heat dissipation by approximately 30%. By offsetting the fin pitch every other row, it significantly enhances performance compared to conventional extruded (comb-shaped) heat sinks. With a fin height of (maximum) 1/2, it can achieve performance equivalent to our conventional extruded heat sinks, allowing for miniaturization and weight reduction of the equipment. Surface treatment can accommodate anodized specifications (colored), and it is capable of precision cutting, precision machining, and drilling. 【Features】 ■ Dividing and offsetting the fins disrupts the temperature boundary layer ■ Increases opportunities for air to collide with the fins, improving heat dissipation performance ■ Suitable for equipment requiring forced air cooling and space-saving designs ■ Surface treatment can accommodate anodized specifications (colored) ■ Capable of precision cutting, precision machining, and drilling *For more details, please refer to the related links or feel free to contact us.
