Some Custom Cold Forged Pin Fin Heat Sink Project

Cold forged pin fin heat sink is also called pin fin heat sink, it has good mechanical properties, high production efficiency, and high material utilization; it reduces production cost and is suitable for mass production. In addition, custom cold forge heat sink has good heat resistance, low thermal resistance and high thermal effect. This ensures heat dissipation and thus the ultimate cooling effect.

Copper forged pin fin heat sink adopts cold forging technology for integrated design and production, with low thermal resistance and good thermal conductivity, which effectively ensures the heat dissipation to achieve the cooling effect. Aluminum pin fin heat sink is integrated with heat-absorbing bottom, no interface impedance; height up to 50, suitable for processing cylindrical heat sink. Secondary machining such as drilling hole, CNC machining is often applied to cold forged pin fin heat sink.

The most common types of cold forged pin fin heat sink are plate fin heat sink, round pin heatsink and oval fin heat sinks.

One of the classic applications for custom cold forged heat sink is in field of LED, pin fin heat sink can also combined with other heat sinks such as friction stir welding pin fin heat sink to a die cast heat sink, then it becomes a cooling plate for automotive industry.

Cold Forged Pin Fin Heat Sink Manufacture Process

Cold forged pin fin heat sinks is a manufacturing process in which the aluminum or copper heat sink is formed by using localized compressed forces. Fin arrays are formed by forcing raw material into a molding die by a punch. The process ensures that no air bubbles, porosity or any other impurities are trapped within the material and thus produces exceptionally high-quality products.

Through this process, we can produce pin fin heat sink with accurate dimension, strong surface and reliable structure. And the fin could be made higher, so that the area of thermal dissipation is expanded.

Custom cold forged pin fin heat sink materials:

The common material used for cold forge heat sink is:

  • AL6063
  • AL1070
  • CU1100

Available surface treatment:

  • Anodizing
  • Nickel plated
  • Chromate
  • Painting/E-coating
  • Powder coating
