Product Advantage
copper heat sink for welding

Copper heat sink for welding advantages as following

1. High density fin, heat dissipation area, light weight. For soldering single fin, the groove can be processed on the bottom plate to insert the fin into the groove for welding. The density of the fin can be up to 1mm and the height can be up to 150mm.

2. The plate can be machined in a complex way, and can be embedded with heat pipes or vampor chamber, greatly increasing the average temperature.

3. The surface of copper welding heat sink will not be oxidized by medium temperature machining.

4. The welding heat sink copper  shape is flexible, which can easily process, install hole position and device avoiding position.

5. Low mold cost, from mini heatsink to large heat sink can be quickly mass production.

6. High reliability, has been widely used in IT equipment and communication equipment heat dissipation.

7. For surface treatment, copper can be welded only after nickel plating, red copper can be welded after rust and oil removal

Production Process

Copper welding heat sink is designed to welding the fins on copper base by environmental protection lead-free medium temperature soldering process. 

The fins can be folded fin, L-fin, zipper fin, or fins with heat pipe, and the material is generally AL6063, AL6061, C1100, etc. 

According to the material, the welding heat sink can be divided into copper welding heat sink, copper soldering heat sink, copper&aluminum composite soldering heat sink, zipper fin welding heat sink, heat pipe soldering heat sink.  According to the process, welding heatsink can be divided into high temperature soldering and low temperature welding. For high temperature welding heatsink need 700-800 degrees to weld. Commonly used welding process is low-temperature soldering, low-temperature welding heat sink temperature between 200-300 degrees, basically no deformation, can be process with high precision processing, can be used with any equipment.

Product Application

Welding heat sinCopper applied to New energy automobile , UPS and energy storage system , large server, large pv inverter , SVG/SVC , etc.
