Pin Fin Heat Sinks

Get A Quote
Pin fin heat sinks utilize densely packed cylindrical or square pins to maximize surface area and turbulent airflow, making them ideal for cooling high heat flux devices with limited space. Unlike traditional finned designs, pin fins excel in omnidirectional airflow environments (e.g., natural convection or low-velocity fans).
 
Our technology optimizes pin geometry and spacing, achieving 25-30% lower thermal resistance than generic pin fin designs. Prototypes delivered in 5-7 days.

Why Choose Pin Fin Designs?

✔️Space Efficiency – Compact footprint for tight PCB layouts.
✔️Omnidirectional Cooling – Effective in multi-directional airflow scenarios.
✔️High Customization – Adjust pin density for specific heat loads.
