This liquid cold plate adopts solid‑state Friction Stir Welding (FSW) technology, with high‑thermal‑conductivity aluminum alloy or copper as the base material. It is manufactured through precision CNC channel milling and integrated FSW sealing. Featuring compact structure and reliable sealing, it serves as a core high‑efficiency liquid‑cooling component for high‑power equipment, widely used in heat dissipation of rack‑mounted devices, precision instruments, industrial power modules and more.

 

 

It applies non‑melting solid‑state welding technology. No brazing filler, pores or cold joints are produced during welding. High‑speed stirring enables plastic bonding of plates for seamless sealing of channel cavities. Compared with traditional brazing and fusion welding, it greatly improves sealing performance and structural strength, passes strict air tightness tests, and eliminates liquid leakage risks.

 

 

 

The base material provides excellent thermal conductivity. With reasonably arranged internal channels, the coolant achieves sufficient heat exchange to rapidly dissipate heat from heat sources, effectively reduce local hot spots and ensure outstanding temperature uniformity.

 

 

Adopting an integrally formed structure, the weld strength is close to that of the base material. It is vibration‑resistant, impact‑resistant and anti‑aging with stable long‑term performance, suitable for continuous‑operation working conditions.

 

 

Full‑process precision machining combined with solid‑state welding eliminates cavity leakage risks, meeting safety requirements of cooling systems for precision equipment, medical instruments and industrial control devices.

 

 

With a flat appearance, it supports customized sizes, channels and connector specifications. Standardized mounting holes facilitate integrated installation in rack‑mounted and modular equipment.

 

 

Rack‑mounted industrial control devices, precision medical instruments, high‑power power modules, energy storage equipment, new‑energy electronic control systems, industrial inverters, testing instruments, etc.

 

 

Customization options include aluminum/copper material selection, channel design, inlet/outlet connector specifications, overall dimensions and surface treatments, tailored to heat dissipation solutions of different devices.
