skived fin heat sink: When passing the machine, scrape the board to a specific angle to form and bend the heat sink. Through repeated cutting, it forms a consistent gap and structure, which can be used to cool high-power equipment under air-cooled conditions. Compared with the stitched fin process, this process can increase the cooling capacity by 8-15%. Leading heat dissipation with innovative high density, high performance, high aspect ratio and excellent performance. 

skiving fin heatsink

Use a sharp knife to produce a scraped heat sink. When the knife passes over the material, it curls a small thickness of metal and then bends it vertically to form a heat sink. The shaved fin is made of a piece of material, and then cut into a certain length according to the requirements of the final application.

The final heat sink can be processed using conventional manufacturing techniques. Because the fins are thin, care must be taken to prevent damage during handling. It is recommended to place a shield above the heat sink to prevent damage.
