Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolytic cell cooling, in particular to an aluminum electrolytic cell cooling device. Background Art

[0002] Electrolytic aluminum is aluminum produced through electrolysis. Modern electrolytic aluminum production utilizes cryolite-alumina molten salt electrolysis. Molten cryolite serves as the solvent, alumina as the solute, carbonite as the anode, and molten aluminum as the cathode. A strong direct current is applied to the two electrodes within the electrolytic cell at temperatures between 950°C and 970°C, creating an electrochemical reaction known as electrolysis.

[0003] Publication number CN219409940U currently discloses a cooling device for an electrolytic cell, which relates to the field of electrolytic cell technology. The cooling device for an electrolytic cell comprises a base plate and a cooling assembly. An electrolytic cell and a cooling box are fixedly mounted on the top of the base plate. The cooling box is located on the right side of the electrolytic cell. The cooling assembly is arranged on the base plate. The cooling assembly comprises a cooling coil. The cooling coil is wound around the outer wall of the electrolytic cell for cooling the electrolytic cell. The cooling device for an electrolytic cell can circulate the coolant inside the cooling coil through a circulating pump, thereby improving the cooling effect of the electrolytic cell and avoiding the situation where the cooling coil heats up and affects the cooling effect. When the heat inside the electrolytic cell is more serious, ice cubes can be added to the inside of the placement box. As a result, during the circulation of the cooling coil, it is difficult for the cooling coil to be cooled by the placement box, thereby reducing the temperature of the cooling coil and improving the cooling effect of the electrolytic cell.

[0004] In order to solve the cooling problem, the existing technology uses a circulating pump to circulate the coolant inside the cooling coil. However, during the circulation of the cooling liquid, the heat absorption effect is lost too quickly, which leads to a low heat absorption cooling effect. Utility Model Content
