Aluminum Plate Heat Sink Extrusion 2 Heat Pipe Friction Welding for Optical Module

This high-performance heat sink combines aluminum extrusion technology with copper heat pipes joined via Friction Stir Welding (FSW). Designed for medium-to-high-power electronic devices, it offers superior cooling capability with structural reliability and ultra-low thermal resistance.

• Excellent cooling capability with no leakage default
• Mass-production cost advantage of aluminum extrusion
• Ultra-fast temperature equalization capacity of heat pipes
• Structural reliability with ultra-low thermal resistance
• Metallurgical bonding eliminates air-gap thermal resistance
• Available with anodizing, black electrophoretic coating, or nickel plating

Aluminum Extruded Main Body: Integrally extruded plate-shaped aluminum base with vertical cooling fins providing large ventilation and heat dissipation area. Two pre-embedded heat pipe grooves accommodate Φ6/Φ8 sintered copper heat pipes.

Heat Pipes: Two copper heat pipes conduct rapid lateral heat transfer and uniform heat spreading, eliminating local hot spots on the aluminum base.

Friction Stir Welding: Solid-state welding with no melting, cold solder joints, or brazing filler. Direct metallurgical bonding between heat pipe walls and aluminum grooves completely eliminates traditional thermal resistance issues.
