Manufacturing method of heat dissipation device of electrolytic copper foil

1. This utility model relates to the technical field of foil producing machines, in particular to a heat dissipation device for electrolytic copper foil.

Background technique:

2. Electrolytic copper foil is an important material for the manufacture of copper clad laminates (ccl), printed circuit boards (pcb), and lithium-ion batteries. In today's rapid development of the electronic information industry, electrolytic copper foil is called the "neural network" of electronic product signal and power transmission and communication. Since 2002, the production value of printed circuit boards in my country has surpassed the third place in the world. As the substrate material of pcb, copper clad laminates have also become the third largest producer in the world. As a result, my country's electrolytic copper foil industry has developed by leaps and bounds in recent years.

3. In the process of using electrolytic copper foil, the copper foil needs to be dissipated after it is rolled down. After the copper foil is at room temperature, the slitting section is carried out. The copper foil with residual heat is cut into small rolls and then rolled. There will be quality defects of copper foil oxidation, and at the same time, a certain amount of dust and impurities will appear at the end when the electrolytic copper foil is used, which will bring unnecessary trouble to the production.

4. Therefore, there is a need for a device that can not only have a certain degree of heat dissipation during the use of electrolytic copper foil, but also have a certain degree of dust removal during use.
