Advanced Brazing Technology
Our vacuum brazing process joins aluminum plates using filler metal with lower melting points than the base material, creating extremely strong joints without residual corrosive flux. This high-end technology provides uniform heating, precise temperature control, eliminates post-cleaning requirements, and minimizes part distortion.
Liquid Cooling System Technology
High-power liquid cooling systems require heat sinks capable of rapid heat absorption. Leveraging the high specific heat capacity of liquids, our systems transfer large amounts of heat through liquid flow, capable of dissipating heat ranging from several hundred watts to over one kilowatt.
Liquid Cold Plate Varieties
- Buried-tube Liquid Cold Plate: Fabricated by grooving plates, burying and welding copper tubes inside, then hermetically sealing via welding. Ensures reliable liquid tightness, operational safety, and high flatness for excellent thermal contact.
- Inserted-tube Liquid Cold Plate: Manufactured by embedding copper tubes onto aluminum plate surfaces using welding or bonding processes, with strict flatness control for minimal thermal resistance.
- Channel-type Liquid Cold Plate: Internal flow channels formed on copper or aluminum substrates through drilling, extrusion, and precision machining, sealed via friction welding or high-temperature brazing.
- Liquid Cooling Block: For high-power chip heat dissipation with internal flow channels created through skiving fin technology to maximize heat exchange surface area.
