[0002] Energy storage batteries are devices that store electrical energy through chemical reactions and release electrical energy through reverse chemical reactions when needed. When charging, the positive electrode material in the energy storage battery undergoes an oxidation reaction, and the negative electrode material undergoes a reduction reaction, converting electrical energy into chemical energy for storage; when discharging, the positive and negative electrode materials undergo opposite reactions, converting the stored chemical energy into electrical energy output. Energy storage batteries usually use rechargeable battery technology, such as lithium-ion batteries, lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, etc. Currently, lithium batteries are more commonly used. Lithium batteries have the advantages of high capacity and high charging and discharging power. Their main application areas are wide, including power system energy storage, transportation energy storage, distributed energy storage, and electronic equipment energy storage. However, current energy storage batteries generate heat during the charging and discharging process, and many current energy storage batteries generally dissipate heat naturally, with poor heat dissipation efficiency, which can easily increase the temperature of energy storage batteries and reduce safety in use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0021] The utility model embodiment discloses a heat dissipation shell structure of an energy storage battery, such as Figure 1-5 As shown, it includes an energy storage battery 1 and a shell 2 sleeved on the energy storage battery 1. The energy storage battery 1 is arranged in a square shape, and a positive electrode and a negative electrode are arranged on the energy storage battery 1. The surface of the shell 2 close to the positive and negative electrodes of the energy storage battery 1 is opened, and at the same time, there is a certain distance between the inner wall of the shell 2 and the surface of the energy storage battery 1. The shell 2 is close to the positive and negative electrodes of the energy storage battery 1. The two opposite sides of the side surface of the energy storage battery 1 are integrally formed with a bending portion 23, and the bending portion 23 is fixed to the side surface of the energy storage battery 1 with the positive and negative electrodes by welding.
[0022] In addition, both ends of the outer wall of the shell 2 are water pipe connectors. Specifically, the water pipe connector includes a quick plug 21 welded to the outer wall of one end of the shell 2, and a quick socket 22 welded to the outer wall of the other end of the shell 2. The quick plug 21 and the quick socket 22 are plugged together. The operator can use a water pipe to connect the quick plug 21 and the quick socket 22. The coolant flows into the shell 2 from the quick plug 21, absorbs the heat generated by the energy storage battery 1, and then flows out from the quick socket 22. When multiple energy storage batteries 1 are spliced together, the quick plug 21 on the energy storage battery 1 can also be plugged into the quick socket 22 on the adjacent energy storage battery 1, so that it is more compact and reduces space occupation.
[0023] In addition, in order to improve the heat dissipation effect, a plurality of heat dissipation fins 3 are arranged between the energy storage battery 1 and the shell 2. The heat dissipation fins 3 are arranged in a U-shaped shape. The heat dissipation fins 3 are sleeved on the energy storage battery 1. One side of the heat dissipation fins 3 is fixedly connected to the side wall of the energy storage battery 1, and the other side of the heat dissipation fins 3 is connected to the inner wall of the shell 2. The heat dissipation fins 3 can increase the heat dissipation area of the energy storage battery 1, thereby improving the heat dissipation effect. At the same time, the heat dissipation fins 3 can play a supporting role between the shell 2 and the energy storage battery 1, so that the shell 2 is not easily deformed. In addition, through holes 31 are opened at both ends of the heat dissipation fins 3 close to the water pipe joint, and the through holes 31 can allow the coolant to flow between the plurality of heat dissipation fins 3. In addition, a plurality of supporting fins 4 are arranged between the bottom of the energy storage battery 1 and the inner wall of the outer shell 2, one side of the supporting fin 4 is connected to the bottom of the energy storage battery 1, and the other side of the supporting fin 4 is connected to the inner wall of the outer shell 2, and both ends of the supporting fin 4 are flush with the two end surfaces of the energy storage battery 1, so that it is convenient for the coolant to flow between the supporting fins 4. The supporting fins 4 can not only support the energy storage battery 1, but also further increase the heat dissipation area of the energy storage battery 1, and the plurality of supporting fins 4 are arranged in a zigzag shape, so that the supporting effect is stronger.
[0024] The implementation principle of the heat dissipation shell structure of an energy storage battery in an embodiment of the utility model is as follows: a coolant is introduced into the quick plug 21 and flows into the shell 2. After the coolant absorbs the heat generated by the energy storage battery 1, it flows out from the quick plug port 22. The multiple heat dissipation fins 3 can increase the heat dissipation area of the energy storage battery 1, so that the heat dissipation effect of the energy storage battery 1 is better. When multiple energy storage batteries 1 are spliced together, the quick plug 21 on the energy storage battery 1 can also be plugged into the quick plug port 22 on the adjacent energy storage battery 1, so that it is more compact and reduces space occupancy.
