However, since a large number of wires need to be connected, the surface is disordered, and the insulation and maintenance are inconvenient, and the manufacturing cost is increased, so that the transformation of technical results is not facilitated.

Detailed Description
The cathode roll is one of the core devices of the foil producing process in the copper foil production. The manufacturing process of the lithium electric copper foil mainly comprises four steps, namely copper dissolving, foil producing, post-treatment and slitting. The cathode roll is also called the heart of lithium electrodeposited copper foil production, and the quality directly determines the grade and quality of the copper foil. In principle, the formation of lithium electrodeposited copper foil is essentially the result of electrodeposited crystallization of copper ions on the surface of a cathode roller, and is a complex process related to current distribution density, comprising diffusion of copper ions to the surface of the cathode, reduction of copper ions to copper metal atoms at the cathode discharge, and arrangement of copper atoms to metal crystals of a certain shape at the cathode. It is essential to ensure that copper ions are deposited uniformly on the cathode, i.e. that the current is distributed uniformly over the roll surface, in order to obtain a copper foil of uniform thickness. The only way to realize the key technology is to ensure that the microstructure of the cathode roller surface material is uniform and fine. When current passes through the conductor, the current is limited by the material, and when the current passes through the contact part, the current amount is relatively large, and the contact area is small, so that the temperature of the contact part can be kept in a high-temperature state, and the conductivity of the conductor can be gradually deteriorated along with the increase of the temperature, thereby influencing the yield of copper foil production.
The conductor cooling structure of the embodiment of the present utility model is described below with reference to the drawings.
In the embodiment of the application, as shown in fig. 1 and 3, a conductor cooling structure comprises a conductor body 1, a shoe pole mounting position 2, a cooling liquid joint 3 and a cooling water pipeline 4, wherein two or more shoe pole mounting positions 2 are symmetrically arranged on the upper surface of the conductor body 1 and are used for transmitting current to a conductive copper ring on a cathode roller, the two ends of the conductor body 1 are provided with concave holes for mounting the cooling liquid joint 3, cooling water enters from one cooling liquid joint 3 and is discharged from the other cooling liquid joint 3 after passing through the cooling water pipeline 4, spiral grooves are formed in the inner side surfaces of the cooling water pipeline 4, cooling water can rotate and rapidly pass through the conductor body 1 through the spiral grooves, heat is taken away, and cooling efficiency is improved.
The utility model relates to a device for repairing electric conductivity of a cathode roller for electrolytic copper foil (hereinafter referred to as the patent) with the number of CN216514191U, which is characterized in that the electric conductivity of a cathode roller end plate is enhanced by adding a metal connecting wire, so that the uniformity of the surface current of the cathode roller is improved, and the quality of the electrolytic copper foil is improved. However, since a large number of wires need to be connected, the surface is disordered, and the insulation and maintenance are inconvenient, and the manufacturing cost is increased, so that the transformation of technical results is not facilitated. In this patent, the inner side surface of the cooling water pipe 4 is provided with a spiral groove, and after the cooling liquid flows in from one cooling liquid joint 3, a spiral flow-shaped passage conductor body 1 is formed in the spiral groove. When the flow of the cooling liquid is in a spiral flow shape, the flow speed of the liquid is increased, and the contact surface of the liquid and the conductor body 1 is effectively increased by adding the processing of special spiral thread grooves, so that the area of the conductor body 1 participating in heat exchange is increased. When heat exchange is performed, the flow speed of liquid is increased within a certain range, the heat exchange effect can be greatly improved, the working temperature reduction amplitude of the conductor body 1 is larger than that of a light pipe, and the copper foil production yield is further ensured.
In order to further optimize the working efficiency of the present application, in an additional feature of the present application, in order to further increase the contact area between the cooling water and the electric conductor body 1, the height of the spiral groove protrusion of the cooling water pipe 4 is not less than three millimeters. In order to enhance the rotation effect of the cooling water, the cooling water is rotated faster, and the pitch of the spiral groove of the cooling water pipeline 4 is one point five to three points five millimeters. In order to facilitate the connection of the cooling water pipe to the coolant connection 3, said coolant connection 3 is provided with an internal thread. In order to further prevent liquid leakage, a sealing rubber ring is arranged at the joint of the inner side of the cooling liquid joint 3 and the cooling water pipeline 4.
When in use, the conductor cooling structure is installed and connected with the corresponding cooling water pipeline, and the conductor can be put into operation.
In summary, in the conductor cooling structure according to the embodiment of the present utility model, the spiral groove is formed in the cooling water pipe 4 in the conductor body 1, so that the cooling liquid flows in from the cooling liquid joint 3, and then the spiral flow-shaped conductor body 1 is formed in the spiral groove. When the flow of the cooling water is in a swirl shape, the flow speed of the liquid in the cooling water pipeline 4 is accelerated, and the special thread-shaped spiral groove is processed, so that the contact surface between the liquid and the conductor body 1 is effectively increased, and the area of the conductor body 1 participating in heat exchange is increased. When heat exchange is performed, the flow speed of liquid is increased within a certain range, the heat exchange effect can be greatly improved, the working temperature reduction amplitude of the conductor body 1 is larger than that of a light pipe, and the copper foil production yield is further ensured.
