[0021] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] 7. Such as Figures 1 to 3 As shown, the utility model provides a new energy iron-lithium battery pack aluminum profile, characterized in that: it includes an aluminum shell frame 1, the same reinforcement members 5 are arranged at the vertices around the aluminum shell frame 1, and the lower end of the aluminum shell frame 1 is fixedly connected to a bottom plate 2, a left side plate 3 is arranged on the left side of the bottom plate 2, and a right side plate 4 is arranged on the right side of the bottom plate 2, and a sealing plate 6 is arranged on the upper side of the aluminum shell frame 1, and guide grooves 7 are evenly distributed on the left side plate 3, the right side plate 4, and the sealing plate 6.

[0024] Furthermore, a rectangular honeycomb panel 41 is provided at the center of the left side panel 3 and the right side panel 4. The overall weight of the battery pack is large, and the honeycomb panels are provided on both sides to reduce the weight of the entire shell and provide protection.

[0025] Furthermore, a graphene heat sink 61 is provided at the center of the sealing plate 6 to improve the heat dissipation efficiency when the temperature is too high during battery operation, and a dustproof net is provided outside the graphene heat sink 61 to prevent accidental dust from entering the battery pack.

[0026] Furthermore, a circular reinforcing rib 51 is provided at the center of the reinforcing member 5, and a transverse beam 54 is provided below the reinforcing rib 51 to play a supporting and reinforcing role. An L-shaped collecting groove 52 is formed between the transverse beam 54 and the outer aluminum shell frame. The water droplets condensed on the battery pack shell can be collected by the guide groove 7 and uniformly guided to the collecting groove 52 to prevent water from entering the battery pack. A protruding block 53 is provided on the right side of the reinforcing member 5, and a cavity is provided between the protruding block 53 and the reinforcing rib 51. The structure is firm and can withstand large pressure and temperature changes. The four reinforcing members 5 have the same structure and are symmetrically placed to enhance the protective effect of the entire aluminum shell.

[0027] Furthermore, the rectangular honeycomb panel 41 is a regular hexagonal honeycomb structure made of aluminum. This structure is similar to many I-beams connected together, and the panel is similar to the flange of the I-beam, which can reduce the overall weight while also being able to withstand the load.

[0028] Furthermore, the interior of the aluminum shell frame 1 is coated with fire-retardant paint to play a flame retardant role and enhance safety.

[0029] Working process: First, the battery is completely wrapped with an aluminum shell frame 1, and the weight of the entire aluminum shell is reduced through the rectangular honeycomb panel 41 in the center of the left plate 3 and the right plate 4. When the battery temperature is too high, the heat dissipation efficiency can be improved through the graphene heat sink 61. At the same time, the dustproof net outside the graphene heat sink 61 can effectively prevent dust from entering the battery pack. When water droplets condense on the outside of the aluminum shell, the guide grooves 7 evenly distributed on the left plate 3, the right plate 4, and the sealing plate 6 can guide the water droplets and collect them into the L-shaped collection groove 52 inside the reinforcement.

[0030] It is worth noting that the interior of the aluminum shell and the aluminum shell frame 1 is evenly coated with fire-retardant paint to achieve a flame-retardant effect and increase the overall safety factor.
