Crimped Fin Heatsink

Crimped fin heat sink is manufactured by bonding the copper or aluminum fins into the matel base(usually copper or aluminum) with slots, This heat sink type can provide a high thermal performance as the fin density and height can be produced highly, the base is usually extruded or machined, if the heat sink is applied in high power application, some heat pipes or vapor chamber can be embeded into the base to improve the thermal transferring ability.

The crimped fin heatsink contains three parts： stamping fin,  base with groove, solder . The base of the can be made in a variety of ways. Extrusion is the preferred method in the field of thermal management and production. Extruded aluminum alloy has excellent thermal conductivity, and extrusion is very easy to manage in production and labor. And CNC machining method  is another solution to make the base. 

Advantages: 

1.    Flexible design, with no tooling parameters limits. 

2.     Stable quality and high reliability.

3.     Has better  thermal Performance than traditional extrusion heatsink.

4.     Simple structure, safe and reliable, mature technology
