The cooling device can remove excess heat generated during the electrolysis process in a timely manner, preventing the electrolytic cell temperature from becoming too high, avoiding problems such as accelerated electrolyte volatilization, melting of the cell walls, and frequent occurrence of the anode effect. At the same time, it can also prevent the electrolyte from solidifying due to excessively low temperatures, which would affect the normal progress of the electrolysis reaction.

Driven by the water pumps, the cooling water circulates in the cooling water pipes, absorbing the heat from the electrolytic cell components, and then flows to the cooling tank for cooling and reuse. However, traditional cooling tanks cool the cooling water slowly, affecting the cooling effect of the aluminum electrolytic cell. Utility Model Content

[0013] This utility model, through the design of a cooling water tank, a first fan, and a condenser plate, enables the cooling device of an aluminum electrolysis cell to achieve the following: During operation, a circulating water pump sends cooling water from one side of the cooling water tank into the circulating inlet pipe, which then enters the circulating water pipe inside the aluminum electrolysis cell.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a cooling device for an aluminum electrolysis cell, comprising: an aluminum electrolysis cell 1 and a cooling water tank 5. A circulating water inlet pipe 2 and a circulating water outlet pipe 4 are provided on one side of the aluminum electrolysis cell 1. The circulating water inlet pipe 2 introduces cooling water into the aluminum electrolysis cell 1, while the circulating water outlet pipe 4 discharges the cooled water after heat absorption out of the aluminum electrolysis cell 1, forming a circulating path for the cooling water. This ensures that the cooling water can continuously remove the heat generated by the aluminum electrolysis cell 1, maintaining the normal operating temperature of the aluminum electrolysis cell 1. One section of the circulating water outlet pipe 4 is located inside the cooling water tank 5. A heat sink 10 is provided on the outer wall of the area of ​​the circulating water outlet pipe 4 inside the cooling water tank 5. The location of the circulating water outlet pipe 4 inside the cooling water tank 5 facilitates heat dissipation of the cooling water within the cooling water tank 5. The heat sink 10 increases the contact area between the circulating water outlet pipe 4 and the air inside the cooling water tank 5, improving heat exchange efficiency and allowing the heat in the cooling water to dissipate into the air more quickly, accelerating the cooling process of the cooling water.

[0023] A water spray pipe 9 is provided on one side of the cooling water tank 5. A connecting pipe 8 is provided between one end of the water spray pipe 9 and the circulating water outlet pipe 4. The water spray pipe 9 has a water outlet hole facing the heat sink 10. The connecting pipe 8 connects the circulating water outlet pipe 4 and the water spray pipe 9, allowing cooling water to flow from the circulating water outlet pipe 4 into the water spray pipe 9. The water spray pipe 9 has a water outlet hole facing the heat sink 10, which can spray the cooling water onto the heat sink 10 in the form of water mist, further increasing the contact area between the cooling water and the air, enhancing the heat dissipation effect, and improving the cooling rate of the cooling water.

[0024] A first fan 6 is located at the top of the cooling water tank 5, above the spray pipe 9. A first baffle 11 and a condenser plate 12 are located on one side of the interior of the cooling water tank 5. A circulating water pump 3 is located at one end of the circulating water inlet pipe 2. The first fan 6 accelerates the airflow within the cooling water tank 5, allowing the air to more quickly remove heat from the cooling water mist sprayed from the heat sink 10 and the spray pipe 9, improving heat dissipation efficiency and helping the cooling water cool down faster, thus better cooling the aluminum electrolysis cell 1. The first baffle 11 guides the flow direction of the cooling water within the cooling water tank 5, allowing it to flow along a set path, increasing the residence time of the cooling water within the tank, and giving it more time to dissipate heat, thus improving the cooling effect. The condenser plate 12 has good thermal conductivity; when the cooling water mist or cooling water comes into contact with the condenser plate 12, heat is quickly transferred to it and dissipated through it, further reducing the temperature of the cooling water and improving the cooling capacity of the cooling device. The circulating water pump 3 provides power for the circulation of cooling water, and can continuously deliver the cooling water in the cooling water tank 5 to the circulating water inlet pipe 2, and then into the aluminum electrolysis cell 1, ensuring the continuity and stability of the cooling water circulation, and ensuring that the aluminum electrolysis cell 1 can be continuously and effectively cooled.

[0025] The aluminum electrolysis cell 1 is equipped with layered circulating cooling pipes, and there are multiple circulating water outlet pipes 4 arranged in layers. This layered arrangement of circulating cooling pipes ensures even distribution within the aluminum electrolysis cell 1, allowing for more comprehensive heat exchange between the cooling water and the cell. This removes heat generated in various parts of the cell, improving cooling uniformity and effectiveness, and preventing localized overheating. The outer wall of each circulating water outlet pipe 4 is equipped with multiple heat sinks 10, arranged at equal intervals. These equidistant heat sinks further increase the contact area between the circulating water outlet pipe 4 and the air, improving heat exchange efficiency and allowing heat in the cooling water to dissipate more evenly and quickly into the air, enhancing heat dissipation and helping the cooling water cool down faster.

[0026] A heat insulation plate 14 is provided on the outer side of the condenser plate 12. The condenser plate 12 is inclined, with the bottom end of the inclined surface close to the first partition 11. A heat-conducting strip 13 is provided on one side of the condenser plate 12. The heat insulation plate 14 reduces heat exchange between the condenser plate 12 and the external environment, prevents the condenser plate 12 from absorbing external heat, and ensures that the condenser plate 12 can continuously and effectively dissipate heat from the cooling water, thereby improving the cooling effect of the condenser plate 12 and thus improving the performance of the entire cooling device. The inclined condenser plate 12 facilitates the flow of cooling water on its surface, allowing the cooling water to better contact the condenser plate 12 and improve heat exchange efficiency. At the same time, the bottom end of the inclined surface close to the first partition 11 can guide the cooling water to flow along a set path, facilitating further heat dissipation and circulation of the cooling water in the cooling water tank 5. The heat-conducting strip 13 increases the heat-conducting area of ​​the condenser plate 12, improves the heat conductivity of the condenser plate 12, and enables the condenser plate 12 to quickly dissipate its own heat. Together with the second fan 7, it further enhances the cooling effect of the condenser plate 12.

[0027] A second fan 7 is installed on one side of the cooling water tank 5, at one end of the heat insulation plate 14, and a second exhaust valve 17 is installed on the other side of the cooling water tank 5, at the other end of the heat insulation plate 14. The second fan 7 can accelerate the airflow on one side of the heat insulation plate 14, carrying away the heat emitted by the condenser plate 12 and improving heat dissipation efficiency. The second exhaust valve 17 can promptly discharge the hot air generated by heat dissipation inside the heat insulation plate 14, maintaining the air pressure balance inside the cooling water tank 5, and also facilitating the entry of fresh air, further improving the cooling effect.

[0028] Inside the cooling water tank 5, a second baffle 15 is located outside the heat insulation plate 14, and a first vent valve 16 is located on one side of the top of the cooling water tank 5. The second baffle 15 can further guide the flow direction of the cooling water in the cooling water tank 5, allowing the cooling water to return to the circulating water pump 3 more smoothly after multiple heat dissipation processes, completing the cooling water circulation. It also helps to increase the residence time of the cooling water in the cooling water tank 5, enhancing the heat dissipation effect. The first vent valve 16 can promptly discharge the hot air generated by the cooling water heat dissipation in the cooling water tank 5, preventing the hot air from accumulating in the cooling water tank 5 and affecting the cooling effect. At the same time, it maintains the air pressure balance in the cooling water tank 5, ensuring the normal operation of the cooling device.

[0029] One end of the circulating water pump 3 is connected to the interior of the cooling water tank 5. The connection between the circulating water pump 3 and the interior of the cooling water tank 5 ensures that the circulating water pump 3 can smoothly draw cooling water from the cooling water tank 5 and deliver it to the circulating water inlet pipe 2, realizing the circulation of cooling water and providing continuous cooling for the aluminum electrolysis cell 1.

[0030] When the aluminum electrolysis cell cooling device is in use, the cooling water from one side of the cooling water tank 5 is sent into the circulating water inlet pipe 2 by the circulating water pump 3, and then into the circulating water pipe inside the aluminum electrolysis cell 1. After the cooling water exchanges heat with the aluminum electrolysis cell 1, it enters the circulating water outlet pipe 4. Then, the cooling water in the circulating water outlet pipe 4 passes over the heat sink 10 and the first fan 6 and is cooled by the air blown by the heat sink 10 and the first fan 6. Then, the cooling water enters the spray pipe 9 through the connecting pipe 8. The spray pipe 9 sprays the cooling water onto the outer wall of the heat sink 10 to increase the contact area between the cooling water and the outside air for further cooling. Then, part of the cooling water mist comes into contact with the condenser plate 12 under the wind force of the first fan 6 for further cooling, and another part comes into contact with the condenser plate 12 after passing the first partition 11 for cooling. Then, the cooled cooling water passes the second partition 15 and re-enters the circulating water pump 3 to realize the circulation of cooling water.

[0031] The cooling water in the entire cooling water tank 5 achieves multiple heat dissipation through the combined action of heat dissipation mechanisms such as heat sink 10, first fan 6, and condenser plate 12, effectively improving the cooling effect of the cooling water and thus ensuring the cooling effect of the aluminum electrolysis cell.
