[최적의 인버터 방열설계를 위해 Skived fin Heat Sink 기술을 사용한 방열판을 소개 합니다.]

 

Skived Fin Heat Sink 장점을 바탕으로 개발에 적극 검토 부탁드립니다.

3.    Fin 두께 : 최소 0.25mm_Gap 1mm / 최대 2mm_Gap 6.5mm

 

This process can enhance 8~15% of the cooling capacity as compared to the stitched fin process.

·     장점 :

Skived fin heat sinks: When passing through the machine, slabs are skived in a specific angle so as to form and bend the fins. With the repetitive cutting, it forms consistent gaps and structures and can be used for cooling high-power devices under air-cooled conditions. This process can enhance 8~15% of the cooling capacity as compared to the stitched fin process.

 

What are the advantages of skived fin heat sinks?

A skived fin heat sink has several outstanding advantages:

(1) One-time forming with no need of further assembling or machining. It is a firm structure with no risk of getting loose or falling apart;

(2) It keeps 100% of the extruded materials thermal conductivity with no loss due to the technique;

(3)It can realize a cooling structure with ultrathin fins, ultra-small gap, and ultrahigh aspect ratio;

(4) It is suitable for large-scale batch production with lower costs;

(5) It is suitable for larger heat sinks with higher stability and easy to maintain.
