Custom Stacked Heat Sinks for High-Power Electronics
HeatsinkMaker manufactures custom stacked fin heat sinks that deliver superior thermal performance for demanding applications. Our stacked fin technology combines high-density aluminum or copper fins with a robust base, creating efficient cooling solutions where space is limited and heat loads are high.
- Aluminum and copper fins
- High-density fin stacking
- Prototype to mass production
Stacked Fin Assembly
Soldered or brazed for low thermal resistance
Why Choose Stacked Fin Heat Sinks
High Surface Area in a Compact Footprint
Stacked fin heat sinks excel in applications requiring high surface area within compact footprints. By mechanically or metallurgically bonding fins to the base, we achieve excellent thermal conductivity while maintaining structural integrity under vibration and thermal cycling.
This design is ideal for power electronics, solar inverters, EV power modules, motor controllers, and telecom equipment.
- High surface area maximizes heat dissipation in space-constrained enclosures.
- Excellent thermal conductivity through low-resistance bonded joints.
- Structural integrity under vibration and thermal cycling.
