Finned Heat Sinks

Get A Quote
Finned heat sinks are thermal management devices featuring an array of extended surfaces (fins) that amplify heat dissipation by maximizing surface area exposed to airflow. They are the most common heat sink type, used across industries to cool components like CPUs, power electronics, and LED modules.
 
We help to optimizes fin geometry for your specific airflow and thermal load, reducing thermal resistance by 20-35% versus standard designs. Prototypes ready in 5-7 day.

Why Choose Finned Designs?

✔️Adaptability – Ideal for low-to-high airflow environments.
✔️Scalability – Extruded, CNC-machined, or stamped for any production volume.
✔️Performance – Balance thermal resistance, weight, and cost.
