01 Friction Stir Welded
Friction welding is a solid - state welding method,
Friction welding compared with traditional welding ,the biggest difference is in the whole
welding process, is to keep the increased temperature due to the energy obtained by the metal to be welded below its melting point. That is, the metal is welded under the solid state which is similar to forging under its thermoplastic state.
As compared to conventional welding, friction welding has the advantages of higher-quality welded connections which meet the requirements of seam strength and base material strength, higher welding efficiency, stable quality, better consistency, and the realization of dissimilar metal welds.
Using friction welding for heat sinks can resolve the technical bottleneck of joining two or more materials to form high-aspect-ratio ultra-wide products. Moreover, its tooling cost is lower with a short cycle time and higher stability. Based on the data that has been accumulated by our R&D team in the long run, Lori thermal has developed several standard materials and we keep enhancing the database of our standard materials so as to provide our clients with more joint solutions for selection.
For customer’s complex joining requirements,Joining dissimilar metals like stainless steel alloys to other metals provides unique design flexibility. This ability also offers us an opportunity to reduce material consumption and shorten machining cycle time.
02 liquid cooling plate
The liquid cooling heat sink made using buried welding technology can effectively avoid the leakage risk of the infusion pipeline,
and the liquid flow is large, the conduction heat resistance is low, and the double-sided device can be installed. we
Applied to New energy automobile , UPS and energy storage system , large server, large pv inverter , SVG/SVC , etc
Skived fin heat sinks
When passing through the machine, slabs are skived in a specific angle so as to form and bend the fins. With the repetitive cutting, it forms consistent gaps and structures and can be used for cooling high-power devices under air-cooled conditions. This process can enhance 8~15% of the cooling capacity as compared to the stitched fin process.
