AL1070 Cold Forging Heat Sink With Anodizing Clear Dimensions 100X70mm

AL1070 Cold Forging Heat Sink With Anodizing Clear Dimensions 100X70 Mm

Quick Detail

Description

    This cold forged heat sink is based aluminum 1070 material to processing, first of all, we check the raw material dimension is fine or not, the second is that according to the drawing, use Hydraulic press machine to do the roughcast, the third is that accroding to the drawing, use the wood machine to cut the  outline dimension, the forth is that use the CNC to do exact dimension, the fifth is do anodizing clear, the last step is riveting, and then inspection/packing. First inspection and patrol inspection are done in processing. 

Note

Cold forged heat sink

An added benefit of this process is that a forged heatsink of the same design can be manufactured with different heights using only one set of forging die. When working with high aspect ratio, or dense fins a forged heatsink has no thermal interface between the fins/pins, and the base which will provide better performance compared with stamped-fin or bonded-fin heat sinks. Heat distribution can be further improved in aluminum heatsinks by embedding a copper inserts into the base during the forging. As this process is fairly expensive, for small volumes it may be worth exploring extrusion with a cross cut to produce square pins. For larger volumes die cast is a good alternative.

Fodor has gained experiences in the manufacturing techniques for high power cold forged heat sink. We have resolved the problems such as the low thermal conductivity of die-casting micro-channels and higher costs for machining micro-channels. We have already applied cold forging heatsink to cooling solutions including high-voltage inverters, wind power converters, and electric motor controllers.

About the cold forging 

A Forged heatsink is manufactured using a modification of this process called cold forging. Cold forging uses high pressure and low temperature to ensure that no air bubbles, or other impurities are trapped in the material. This improves the thermal properties of the heatsink, and increases the density of the material.
