Match the Curve of Your Air Path

In tightly integrated thermal systems—such as server chassis, telecom line cards, or industrial inverters—cooling air is often guided through curved ducts or shrouds to reach hotspots. Straight-fin heat sinks create abrupt flow transitions at these bends, causing separation, recirculation zones, and uneven cooling. The Curved Fin Radiating Heat Sink for Ducted Flow solves this by shaping each fin to follow the natural streamline of the enclosed airflow path. This curvature maintains attached flow, reduces turbulence losses, and ensures consistent velocity across all fins—even around corners.

Advantages of Aerodynamically Contoured Fins

• Lower System Pressure Drop: Up to 20% reduction vs. straight fins in bent-duct configurations.
• Uniform Thermal Distribution: Eliminates cold spots caused by flow detachment.
• Seamless Integration with Shrouds: No gaps between sink and duct wall—maximizes flow guidance.
• Custom Radius Options: Available in standard arcs (e.g., 90°, 120°) or tailored to your duct geometry.

Ideal for High-Efficiency Data Center and Industrial Cooling

This design is engineered for blade servers, liquid-to-air heat exchangers, variable-speed drives, and outdoor power cabinets where airflow must navigate tight turns without losing momentum. In these applications, every pascal of static pressure matters. By enabling smooth Radiating Fin Cooling within complex duct networks, this sink supports higher component density without oversizing fans. Its stream-aligned Radiating Fin Design ensures that thermal performance isn’t compromised by mechanical packaging—delivering exceptional Radiating Fin Efficiency in real-world constrained layouts.

Frequently Asked Questions

Q: Can curved fins be extruded?
A: Standard extrusion produces straight profiles; curved versions require skiving, stamping, or CNC bending—but are cost-effective for mid-volume runs.

Q: Does curvature reduce surface area?
A: Slightly—but the gain in convective heat transfer coefficient more than compensates.

Q: Is it suitable for open-air use?
A: Less beneficial—curvature’s advantage is maximized only when paired with matching duct or shroud geometry.

The Curved Fin Radiating Heat Sink for Ducted Flow doesn’t resist the airflow—it flows with it. Through its aerodynamically harmonized Radiating Fin Design, it achieves superior Radiating Fin Efficiency and reliable Radiating Fin Cooling wherever air must bend to do its job.
