　擠壓成型散熱器一般為高功率散熱元件和散熱系統，文軒熱能根據現有成熟的鋁擠型型材散熱器技術，可以提供可靠的自然對流環境解決方案。通過模具實現鋁擠壓成型，可實現復雜的散熱齒片結構。這些復雜的散熱齒片更大提高了散熱表面面積，同時降低了鋁塊加工的成本和時間。
為什么要使用文軒熱能擠壓散熱器？
（1）比沖壓成型的散熱片更高效；（2）比機械加工更節約成本；（3）有多種標準形狀和尺寸可供選擇；（4）輕松的定制實現比銅更輕，優勢明顯；（5）MAX CLIP扣件系統無需安裝硬件和工具。

Tooth features

Fin profile #1: The fin tip has the same thickness as the fin base. The aspect ratio is smaller than 10 and this structure is suitable for cooling by natural convection.

Fin profile #2: Smaller fin tip with a larger fin base and it forms a taper. High aspect ratio which is suitable for forced air cooling products. It is more lightweight under the premise of no performance reduction.

Fin profile #3: Smaller fin tip with a larger fin base and it forms a taper. Knurls are added to the fin surface. Both fin profiles #1 & #2 are suitable for this type of design to increase the surface area. The size of the knurls is inversely proportional to the aspect ratio.
