"220V Cooling Fan" imprint (Stampings) fin
Copper or aluminum can be used the way into a desired embossed shape. Such low-cost process for bulk supply, can be used for low heat density devices. The imprint of the device at the assembly also has the convenience of automation, thus further reducing costs.
"220V Cooling Fan" extrusion (Extrusion) fin
Extrusion manufacturing methods by the material flows into the mold under high pressure to force 孔中成 shape and makes solid, such as converting a continuous strip section. Extrusion-shaped heat sink manufacturing methods are the most widely used, by the amount of equipment investment medium. May be returned by way of a rectangular cross acicular fins, the fins may be serrated to produce 10 to 20% increase in efficiency, but will reduce the speed of extrusion. "220V Cooling Fan" high aspect ratio can be as high extrusion restricted to 6, you can use a special mold design to the high aspect ratio of 10.
