Compact Heatpipe-Embedded Fin Heat Sinks for High-Efficiency Cooling

Need powerful cooling in a tight space? We manufacture heatpipe-embedded heat sinks that combine high-conductivity copper heatpipes with lightweight aluminum bases and dense fin stacks. Ideal for power modules, EV electronics, telecom, and other passively or actively cooled systems.

Using precision grooves and press-fit or soldered assembly, multiple copper tubes are embedded directly into the base, then coupled to extruded or skived fins—delivering fast heat spreading and large surface area with excellent mechanical stability.

Skived fin structure for high surface area

Key Advantages

✅ Rapid heat conduction via copper heatpipes embedded in the base
✅ Dense aluminum fins (extruded / skived) maximize convection surface
✅ Custom pipe layouts, base thicknesses, and mounting interfaces
✅ Assembly options: press-fit, soldering, or bonding per project need
✅ Optimized for forced or natural convection environments

Common Applications

✔ EV control units & battery pack thermal management
✔ IGBT / MOSFET / rectifier power modules
✔ Outdoor telecom, servers, and network systems
✔ Lighting drivers and high-efficiency inverters

Precision Fabrication & Support

✔ 2D/3D drawing support, routing optimization, and DFM feedback
✔ CNC base machining; fin profile selection (pitch, height, thickness)
✔ High-pressure leak testing and dimensional inspection
✔ Fast prototyping with scalable long-term supply

For a faster quote, include:

• Heat load (W) & target case temp • Hot-spot size / position • Max footprint & height • Airflow (CFM) / fan model • Mounting holes & keep-outs • Finish / corrosion requirements • Environment (ambient, dust, altitude)

FAQ

Can you design pipe routing for uneven heat sources?

Yes. We tailor the pipe count and routing to match heat-source locations, spreading heat to the fin stack efficiently.

Which assembly method should I choose: press-fit or soldering?

Press-fit offers speed and cost efficiency; soldering improves contact conductance. We’ll recommend based on your targets.

Do you support forced and natural convection?

Yes. Fin pitch and height are selected for your airflow profile (fan-driven or passive) and acoustic constraints.
