[0002] Photovoltaic ribbon is an important material used in the manufacture of solar panels. It is usually composed of an aluminum or copper foil substrate and a silicon wafer or other semiconductor material covering it. The role of photovoltaic ribbon is to connect the various components in the solar panel to form a circuit, so that the solar panel can effectively convert solar energy into electrical energy.

[0003] The prior art discloses a cooling structure for tinning production of photovoltaic welding strips with application number: CN201922185526.2. The cooling structure for tinning production of photovoltaic welding strips includes: a cooling box and a motor; a partition, and the partition is fixedly connected to the right side of the cooling box. The cooling structure for tinning production of photovoltaic welding strips provided by the utility model has three rollers passing through the photovoltaic welding strips during the movement to the left, which increases the contact time with water and makes the cooling effect better. At the same time, after being cooled by water, it is cooled and dried by the heat dissipation fan, and the cooling is more thorough. At the same time, the heat dissipation fan can also dry the photovoltaic welding strips after water cooling, saving working time. When the water vapor generated during the cooling of the photovoltaic welding strips carries a large amount of heat and passes through the folding tube, the heat is transferred to the water tank, and the water vapor turns into water again and returns to the cooling box through the second connecting pipe, which not only reasonably and effectively utilizes the heat in the water vapor but also saves water resources, so that water is recycled and energy-saving and environmentally friendly.
