Aluminum Cooling Plates for Laser Equipment
Aluminum cooling plates, also known as cooling plates or fiber laser cooling plates, are core heat dissipation components for high-power lasers. Mostly made of aluminum alloy, they circulate cooling water through internal flow channels to rapidly remove heat generated by heat sources such as pump sources and gain fibers, ensuring stable laser output and precise wavelength.
Core Definition & Application Scenarios
Laser Cooling Plate: A general term for aluminum liquid cooling plates applied to various laser devices (fiber, solid-state, semiconductor), covering power levels from hundreds of watts to tens of kilowatts.
Fiber Laser Cooling Plate: Specially designed for fiber lasers. It realizes temperature equalization and heat dissipation for precise heat sources including pump source arrays, fiber combiners and laser heads, featuring low thermal resistance, excellent temperature uniformity, vibration resistance, insulation and corrosion resistance.
6061‑T6: The most widely used grade. Thermal conductivity: approx. 180 W/m*K. High strength, easy to machine, available with anodizing/hard anodizing treatment and cost-effective.
3003: Thermal conductivity: approx. 190 W/m*K. Good corrosion resistance and brazeability, commonly used for vacuum brazed cooling plates.
7075: Aerospace-grade alloy with high strength. Thermal conductivity: approx. 130 W/m*K. Applied to compact high-power devices working under severe vibration.
Copper-Aluminum Composite: Aluminum substrate embedded with copper flow channels/tubes. Combines light weight and high thermal conductivity (401 W/m*K), ideal for equipment above 2 kW.
Main Structures & Manufacturing Processes
Tube-Embedded Cooling Plate (Most Popular)
Process: Groove milling on aluminum base -> Embedding copper tubes -> Vacuum brazing / Laser welding -> Surface treatment.
Features: Reliable sealing, working pressure 10-15 bar, flexible flow channel design and easy maintenance. Suitable for medium and small-batch production with various specifications.
Vacuum Brazed Microchannel Cooling Plate
Process: Lamination of multiple aluminum sheets -> Diffusion welding / Vacuum brazing -> Integral forming.
Features: Dense flow channels, large heat exchange area and superior temperature uniformity (surface temperature difference ≤1℃). Applicable to high-power equipment above 3 kW and mass production.
Friction Stir Welding (FSW) Cooling Plate
Process: Groove milling on aluminum base -> Cover plate fitting -> Seamless FSW.
Features: No welding filler required. Weld strength ≥ 90% of base material, low deformation (≤0.1 mm/m) and high pressure resistance. Perfect for scenarios requiring high vibration resistance and long-term reliability.
Laser Welded Cooling Plate
Process: Laser fusion welding on thin plates (0.8-1.5 mm) to form sealed flow channels.
Features: High machining accuracy and small heat-affected zone. Designed for ultra-thin and miniaturized cooling plates.
Flow Channel Layout: Parallel channels for pump source area (low resistance & uniform temperature); Serpentine channels for fiber area (extended heat exchange); Counter-flow design (reduces temperature difference between inlet and outlet).
Fiber Groove: Smooth and burr-free with fillet radius R≥0.5 mm to prevent damage to fiber coating.
Insulation & Voltage Resistance: Anodized layer thickness ≥50 μm; Withstand voltage ≥2 kV (prevents electric leakage of pump sources).
Vibration Reinforcement: Reinforced mounting holes; Flow channels arranged away from high-stress areas to adapt to vibration in industrial sites.
Performance Comparison: Aluminum vs Copper
Aluminum Cooling Plate: Light weight (about 1/3 of copper), low cost (about 1/2 of copper), easy to machine and excellent anodic insulation. Slightly lower thermal conductivity (180 W/m*K vs 401 W/m*K). Suitable for medium & low-power equipment, lightweight designs and cost-sensitive projects.
Copper Cooling Plate: Extremely high thermal conductivity and outstanding heat dissipation capacity. Drawbacks: heavy weight, high cost, difficult machining and prone to oxidation. Applied to ultra-high-power equipment (≥6 kW), compact spaces and scenarios demanding extreme heat dissipation.
Common Specifications (Customizable)
Dimensions: Length 200-800 mm, Width 100-400 mm, Thickness 8-20 mm
Flow Channel: Width 3-8 mm, Height 2-5 mm, Pitch 5-15 mm
Connectors: Standard G1/4, G3/8, M14×1.5 or customized quick connectors
Selection Guidelines
≤1.5 kW: 6061 alloy with embedded copper tubes & laser welding, high cost performance
1.5-3 kW: 6061/3003 vacuum brazed microchannel type, good temperature uniformity and high reliability
≥3 kW: Copper-aluminum composite or vacuum brazed type, low thermal resistance and high pressure resistance
High vibration / Outdoor use: Friction stir welding + hard anodizing, high structural strength and corrosion resistance
