Liquid-cooled Heat Sink

We produce liquid-cooled heat sinks sealed with friction stir welding (FSW)
Friction Stir Welding (FSW) is a solid-state joining process in which the welding
is done with frictional heat generated between the welding tool shoulder / pin
and the materials of the work pieces. The heat causes the stirred materials to
soften without reaching the melting point so that a solid-state joining could be
achieved. The joint has a monolithic structure with mechanical properties
similar to the parent materials of welded parts.
The FRICTION STIR WELDING TECHNOLOG is with outstanding advantages:

  • Excellent weld quality and repeatability
  • High reliable sealing
  • With high strength similar to the parent materials of welded part
  • No pores
  • No flaws
  • No residual stress
  • No deformation
  • No smoke dust, no splash, very low noise in production

The heat sinks can be made with copper or aluminum and coated according to
customer specification.
Our design is based on the ICEPAK - the most advanced thermal design
software for electronic equipment, and the validity of the thermal and flow
performance is verified by simulation and testing.
The welding quality is checked with X-ray tester and the leakage test is made
according to customers’ requirements, for example 6~12 bar applied for 10-24
hours with pass criterion of pressure loss at the end of test < 0.2 bars.
