Ravoteck Future Technology Co. Ltd

System Solution: Home>System Solution; Ravoteck can not only provide customers with sample and mass production of complete products, but also design thermal system from basic information. According to the different needs of customers, provide design, production and service.

Cutting and adjusting fin with certain spacing on a whole piece of material. Can produce products with large ratio of fins' thickness to fin’s height.: The whole product is integrated, reducing the thermal resistance between fin and base
Suit for various and small production demands
Compared with the stack fin，no special tooling is needed basically.
Materials: copper and aluminum

Gap between two fins
the length of product: 1-50mm; <510mm; <120mm; （鋁鏟齒）0.1-2.0mm
（銅鏟齒）0.1-1.2mm; 0.1-10mm; 4000mm

This process is suitable for mass production of price-sensitive products. Stable quality and controllable cost. It is the process with the longest application practice, the widest scope and the most stable parameters in the thermal industry.: Copper parts and aluminum parts can be welded together.
Need to customized specific tooling to achieve mass production rapidly.
Can produce products with unique shapes.

Through mechanical structure design, the two parts need to be combined are fixed together by interference size or press fit (no contact material is added between these two parts). This process can realize the combination of aluminum and copper, aluminum and aluminum without nickel plating on aluminum, which is environmentally friendly and efficient. However, due to design requirements, it is not possible to change any products to pressfit.: Aluminum material can be combined with aluminum material or copper material without nickel plating.
The combined strength can be ensured to meet the requirements of conventional thermal products.
It is necessary to precisely design the toolings and fixtures.
Due to structural limitations, some products cannot be changed to pressfit process.

At present, this process is mainly used for combining two parts, so as to produce large-scale products or liquid cold plates and other products. The weld seam welded by the process has compact structure and is often applied to the production of liquid cooling plate tunnel. Suitable for welding the same material to each other. Due to the different melting points of different materials, this process will be a little difficult, and Ravoteck is currently researching and developing them.: Compared with the welding method in the furnace, the FSW’s efficiency is high
The welding seam has high bearing capacity.
When used in liquid cooling plate production, the holes on the product surface should not be too close to the tunnel.
The welding depth can be adjusted according to the tooling, but it is also limited by the machine.

Impact of other parameters When design, heat pipes should be reasonably designed with thickness, bending angle, etc.
