Product Description

A cold forged heatsink is a good alternative to casting to form complex shapes with excellent thermal conductivity. The Cold forging process can make almost perfectly straight allowing for more fins per square mm. Cold forged heatsink shapes include plate fin heat sinks, round pin heat sinks, and elliptical fin heat sinks. Cold forged heatsink manufacture lends itself very well to using copper because high temperatures are not required to shape the copper heatsink, and it can be formed with minimal damage. Secondary machining operations such as hole, chamfer, and steps can be usually included in the cold forged heatsink manufacture reducing waste. Forging involves the shaping of metal using localized compressive forces. 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. Radian Thermal Products utilizes special open die tooling and intense pressure to produces high precision heatsinks with high aspect ratios. A Forged heatsink is typically manufactured one part at a time, and can be can be made from AL 6063 or C1100. Aspect ratio up to 35:1 are feasible, and no draft angles required on fins. Fins can be round, elliptical, straight or any combination on the same part.
