Stacked fin heat sink solutions offer better performance when compared to typical extrusion heatsinks, due to thinner fin profiles leading to higher surface area and lower pressure drop.

Stacked fin and folded fin heat sinks are manufactured by stamping sheets of rolled aluminum or copper into a tightly formed array of fins. A progressive tool is used in the stamping process to cut features and then interlock the fins together. Snapped fin heat sinks are most commonly integrated with heat pipes at the condenser end where they are used to cool the heat pipes, thus enabling the phase change.

PT heat sink can customize stacked fin heat sink based on your thermal requirement and application. More important, we can design heat sink and run simulation to find the best and cost reasonable solution for your application. From design to prototype to production, PT heat sink is your one-stop supplier.
