Description

Technical Field

[0001] The present invention relates to the technical field of energy storage batteries, and in particular to an energy storage lithium battery device capable of rapidly dissipating heat and lowering temperature. Background Art

[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. At the same time, due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream of energy storage power sources. However, energy storage lithium batteries will generate a lot of heat during use. Therefore, it is particularly important to quickly dissipate heat for energy storage lithium batteries, and thus energy storage lithium battery devices that can quickly dissipate heat and cool down are needed.

[0003] However, the existing energy storage lithium battery devices that can quickly dissipate heat and cool down still have certain defects when used;

[0004] For example, a shell proposed in application number CN202311510106.1 comprises an outer shell and a cover detachably connected to the upper end face of the outer shell, a ventilation window is arranged on the outside of the outer shell, a buffer roll is fixedly connected to the inner wall of the outer shell, the cross section of the buffer roll is wavy, an inner frame is fixedly connected to the inside of the outer shell, and a bottom plate is fixedly connected to the bottom of the outer shell. The application arranges a buffer roll and an inner frame inside the outer shell, wherein the battery is installed inside the inner frame through a battery mounting frame, and three groups of structural reinforcement components are integrally connected through a connecting plate, which can enhance the energy absorption threshold, and the energy absorption box will deform with the groove as the point to absorb energy, thereby reducing the impact of external impact on the battery inside the inner frame, and the reinforcement frame corresponds to the position of the middle structural reinforcement component, which can further improve the threshold of the impact force that the reinforcement frame can withstand, and cooperates with the outer mesh sleeve and the inner mesh sleeve arranged at intervals, which can protect the battery to the maximum extent and effectively prevent the battery from being damaged by impact. In actual use, there are still the following problems;

[0005] The application provides a plurality of air holes on the outside of the buffer roll to cooperate with the cooling fan for heat dissipation. At the same time, the heat dissipation channel can improve the flow effect of the heat dissipation airflow, and the heat dissipation airflow passes through the outside of the battery assembly, so that the heat generated by the battery is taken away with the flow of the heat dissipation airflow to achieve heat dissipation. However, the heat dissipation efficiency of heat dissipation achieved only by air flow is low, and it is easily affected by the external temperature, which reduces the heat dissipation efficiency and effect;

[0006] A lithium energy storage battery with uniform heat dissipation, such as that proposed in application number CN202410340028.3, relates to the technical field of lithium energy storage batteries, including a battery box, wherein a plurality of water cooling components are arranged inside the battery box. In this lithium energy storage battery with uniform heat dissipation, the water cooling plate has two flow channels, and the water inlet and outlet directions are opposite. When the coolant in the first flow channel circulates from left to right, the coolant absorbs the heat of the battery cell and the temperature gradually increases, and a temperature difference is generated on both sides of the water cooling plate. At this time, the coolant in the second flow channel circulates from right to left to cool the side of the water cooling plate with a higher temperature. The second flow channel and the first flow channel cooperate to have a complementary effect, which can reduce the temperature difference of the water cooling plate, thereby being able to dissipate the heat of the battery cell more evenly, greatly improving the heat dissipation effect. In actual use, the following problems still exist;

[0007] This application uses water cooling to dissipate heat from the energy storage lithium battery. The heat dissipation liquid after absorbing heat from the energy storage lithium battery will carry the heat into the storage container of the heat dissipation liquid, and the heat dissipation liquid in the storage container needs to be cooled by a cooling structure. It is not convenient to use the structure of the energy storage lithium battery itself to cool the heat dissipation liquid, which reduces the use effect.

[0008] In view of this, we conducted in-depth research on the above issues, which led to the present case.

[0009] In view of the above problems, an innovative design is carried out based on the original energy storage lithium battery device which can quickly dissipate heat and cool down. Summary of the invention

[0022] By adopting the above technical solution, the setting of the detachable filtering mechanism can prevent external dust from entering the interior of the protective shell and causing pollution to the interior of the protective shell. At the same time, the detachable filtering mechanism can also be easily disassembled, which is conducive to cleaning the dust adhered to the surface after disassembly, thereby improving the convenience of cleaning.

[0023] Preferably, the liquid cooling drive mechanism includes a positioning sleeve, a conveying hose, a transmission seat, a roller and a liquid cooling heat exchange tube.

[0026] The above technical solution is adopted to facilitate the operation of the liquid cooling drive mechanism in cooperation with the double-head servo motor and the motor shaft, so that the heat dissipation liquid inside the bottom sealed liquid storage tank can be extracted during the operation, and the heat dissipation liquid can flow inside the liquid cooling heat exchange tube and finally re-enter the sealed liquid storage tank to realize circulation, which is beneficial to absorb the heat inside the protective shell during the circulation process to realize liquid cooling heat dissipation, and cooperate with the above-mentioned air cooling heat dissipation to perform double heat dissipation on the energy storage lithium battery device, thereby improving the heat dissipation efficiency and effect.

[0032] The rotation of the motor shaft can also utilize the meshing connection between the active bevel gear and the driven bevel gear to drive the rotating rod and the stirring blade to rotate, which is beneficial for the stirring blade to evenly stir the heat dissipation liquid inside the sealed liquid storage tank during rotation, and is beneficial for the heat dissipation liquid to evenly contact with the heat dissipation fins, thereby improving the thermal conductivity and uniformity of the heat dissipation fins.

[0036] In summary, liquid cooling combined with air cooling can improve the comprehensive heat dissipation effect and efficiency of the energy storage lithium battery device;

[0037] Moreover, the motor shaft can also drive the second cooling fan to rotate during the rotation process, and the second cooling fan cooperates with the cooling fins to perform air cooling on the cooling liquid inside the sealed liquid storage tank on the basis of natural cooling, thereby improving the cooling linkage and efficiency of the cooling liquid. The rotation of the motor shaft can also utilize the meshing of the active bevel gear and the driven bevel gear to drive the rotating rod and the stirring blade to rotate, which is beneficial for the stirring blade to stir the cooling liquid inside the sealed liquid storage tank during rotation, and then facilitates the cooling fins to evenly extract the heat in the cooling liquid, further improving the cooling efficiency of the cooling liquid.
