It consists of a series of metal plates, which usually have fine grooves to increase the surface area and improve the heat exchange efficiency. A plate heat exchanger usually consists of multiple plates that are fixed in a frame to form a stacked structure, and the copper foil automatic winding device of a plate heat exchanger refers to a device specially designed to automatically roll, flatten and cut the copper foil into the required size when producing the heat transfer plate of a plate heat exchanger. In the manufacturing process of a plate heat exchanger, copper foil is usually required as the material of the heat transfer plate. These copper foils need to be precisely processed into the appropriate size and shape to ensure the performance and efficiency of the heat exchanger.

[0003] After searching, the Chinese patent document announcement number: CN218836406U discloses a copper foil tinning device that can automatically load and unload materials, including a workbench, a copper foil unwinding reel, a feeding guide mechanism, a tinning mechanism, a lifting soldering mechanism, a receiving guide mechanism and a copper foil receiving reel. The copper foil strip drawn from the copper foil unwinding reel is conveyed to the bottom of the lifting soldering mechanism through the feeding guide mechanism, and the receiving guide mechanism can pull the copper foil strip that has been soldered to the copper foil receiving reel to complete unloading and winding.
