Vacuum Brazed Liquid Cold Plate Heat Exchanger Anodizing for Optical Module Cooling

Vacuum brazed liquid cold plates are manufactured with high-precision vacuum brazing technology. Composed of upper & lower cover plates and an internal channel plate precisely laminated together, they are integrally brazed in a vacuum environment. With well-structured internal micro-channels or conventional channels and sufficient heat exchange area, they are mainstream liquid-cooling components for high-power electronic devices, suitable for heat dissipation of rack-mounted equipment, industrial electronic controls, energy storage systems and medical instruments.

Multi-layer plates achieve metallurgical bonding through uniform melting of special brazing filler inside a high-vacuum sealed furnace. Oxygen-free welding throughout the process delivers dense welds free of oxidation, pores and cold joints. The finished plate features high flatness, non-deformed channels and stable air tightness.

• High Heat Exchange Efficiency: Dense micro-channels can be fabricated inside, providing large contact area for coolant. It realizes fast heat dissipation and excellent temperature equalization to effectively control hot-spot temperature.
• Excellent Sealing Performance: Welded under vacuum with no residual impurities, it features strong leakage resistance and can pass strict tests such as helium leak detection for stable long-term operation.
• Slim & Compact Structure: Integrally formed with controllable thickness and light weight, it is easy to install and compatible with modular and rack-mounted equipment assembly.
• Wide Compatibility: Available in aluminum alloy and copper-aluminum composite materials. Flexible channel layout; inlet/outlet ports, mounting holes and overall dimensions can be customized.
