We are a professional thermal factory offering one-stop OEM & ODM customization service for heat sinks and liquid cold plates. Our copper folded fin (corrugated fin) heat sinks are fabricated by precision continuous folding of thin copper sheet, then vacuum brazed to the base plate. High fin density creates ultra-large heat exchange area within limited space, ideal for high heat flux scenarios. We also develop and manufacture custom liquid cold plates with internal micro channels, supporting liquid cooling for high-power equipment. Thermal simulation, prototype sampling and mass production are all available.
Key Advantages
✅ High-performance Copper Folded Fin Structure
Made of high-conductivity C1100 oxygen-free copper. Continuous folded corrugated fins, higher fin density than extruded or skived heat sinks. Optimized airflow channels, low turbulence loss. Vacuum brazing bonding ensures low interface thermal resistance, stable for high TDP loads.
✅ Full Custom Liquid Cold Plate Capability
Available in copper / aluminum materials. Processes: CNC deep hole drilling, vacuum brazing, friction stir welding (FSW). Internal straight fins, pin fins, micro-channel structures optional. Inlet/outlet position, thread specification, outline size fully customizable. 100% air tightness & leak testing before deliveryglaciercoo....
✅ In-house Factory, One-stop Thermal Solution
Own workshop for stamping, folding, brazing, CNC machining, surface treatment. Our engineering team provides DFM review, CFD thermal simulation, design optimization. Small batch prototyping and large-volume order supported.
✅ Flexible Custom Parameters
Adjust fin thickness, fin height, fin pitch, wave shape for folded fins. Change cold plate flow path, thickness, mounting hole layout. Surface options: nickel plating, gold plating, anodizing, passivation for anti-corrosion and anti-oxidation.
Internal channel: Straight channel, pin fin, micro-channel, folded fin insert
Test: Water pressure test, helium leak detection
Connector: NPT, G thread, quick coupling customizable
Application Scenarios
Server, high-power converter, IGBT, laser equipment, energy storage, new energy, medical device, communication power supply, automotive electronics, industrial control, high-performance computing.
