Heat Sinks That Have Been Swaged

Swaged heat sinks are created using a swaging manufacturing method, which is similar to forging. Swaging is the technique of shaping metal to a die. Swaged heat sinks are generally excellent performers and are well suited to high-power applications, such as power supply and other similar equipment. Swaged heat sinks are typically bulky and have little airflow control.


Swaged fin

Swaged fins are an excellent high-power solution for forced or natural convection. Swaging is used to cut and bond individual straight fins into a grooved base plate. Fins on a zipper/skived or folded fin are usually thicker than those on a zipper/skived or folded fin. On the same heat sink, aluminum and copper fins can be mixed to improve performance without adding weight. Graphite fins can be used if weight is particularly critical, although they are more sensitive and require extra attention.


Swaged fin heat sinks are typically designed for physically large applications with modest performance requirements. Individual metal fins are swage (roll-pressed) or pressed to a foundation to create swage fin heat sinks. Pressing and deformation are used to glue the pieces together. The fundamental benefit of this heat sink is that it can be employed in huge applications. The main disadvantage is that the production process isn’t as automated as it is for stamped, extruded, or folded fin heat sinks, resulting in a high swaging fin cost.

Cooling Source design swaged fin heatsinks to maximize the surface area in contact with the coolant fluid.

CSI’s manufacture swaged heatsinks from either aluminum or copper metal sheets or extruded. Aluminum costs less than copper. However, copper provides higher levels of thermal conductivity.

This type of heatsink is designed to meet particular needs. Should you have any questions about using swaged heatsinks, our knowledgeable consultants can discuss your specific needs and answer any questions you may have. It is important to choose the right product for cost, delivery time, and effectiveness. The choice you make can be crucial to your success.

Swaged heatsinks are designed for high-power applications accompanied by low thermal resistance. Therefore, forced air cooling is required for these products.

Benefits of Swaged Fin

  • Better aspect ratio than thin fin extrusions
  • Doesn’t require interface material between the base and fins.
  • Fins can be as thin as 0.008. “
  • Fins can be 2 inches or higher
  • Environmentally friendlier than soldered fin heat sinks
  • The strong mechanical bond between the base and the fins
  • Excellent process for large heat sinks

Swaged Fin, better thermal resistance than bonded fin heat sinks.
