Folded Fin Heat Sink for Power Electronics
The Folded Fin Liquid Cooling Heat Sink is a high-performance thermal management component specifically engineered for high-power electronic devices such as IGBT modules, battery cells, and traction converters. It is constructed by vacuum brazing, a precision-machined Water-cooled plate with high-density folded fins into a single integrated unit. This folded fin structure significantly increases the internal heat exchange area within a compact space, enabling efficient convective heat transfer as the coolant (e.g., water-glycol solution or fluorinated fluid) flows rapidly through the fins, effectively dissipating heat generated by core components.

High-Performance Heat Dissipation Capability
We can manufacture high-density folded fins combined with Water-cooled plate structures, delivering 40%+ more heat transfer area compared with conventional straight-fin designs.
As a folded fin heat sink for 100 kW power modules, this structure provides strong support for high heat-flux requirements under proper cooling conditions.
01
Compact and Lightweight Structural Design
Using 6061 / 6063 aluminum, we produce high-strength and lightweight folded fin heat sinks.
The folded-fin design significantly reduces overall part size while improving specific power density, making it ideal for space-constrained applications such as EVs, energy storage systems, and rail transit equipment.
02
Reliable Vacuum Brazing Capability
We provide vacuum brazing for multi-layer structures including folded fins, chambers, and cover plates.
Combined with leak-tightness testing and visual inspections, our process ensures stable, reliable, and durable cold plate performance.
03
Fully Customized Manufacturing
Based on your drawings, we offer complete customization of fin density, channel layout, interface configurations, and surface treatments (such as anodizing or nickel plating). This allows precise adaptation to different application scenarios and thermal design requirements.
