However, to a certain extent, the following defects still exist.

[0004] For example, the heat sink and the base of the above device are fixedly connected by welding, and the heat sink cannot be disassembled.

[0021] See also Figures 1-6 A high-efficiency heat dissipation aluminum plate for a power battery base includes a base body 1, an inner cavity of the base body 1 is fixedly connected to a battery body 6, support base plates 5 are welded to the left and right sides of the bottom of the base body 1, a heat dissipation plate 4 is slidably inserted between the left and right support base plates 5, a positioning mechanism 3 is movably connected to the inner cavity on the front side of the support base plate 5, and a sealing plate 2 is fixedly connected to the top of the base body 1;

[0022] See also Figure 5 The heat sink 4 includes an aluminum plate body 14, a heat sink fin 13 is welded to the bottom of the aluminum plate body 14, and positioning holes 12 are opened on both sides of the left and right sides of the top front side of the aluminum plate body 14. By setting the positioning holes 12, it has a through positioning function, which can facilitate the positioning of the insert plate 8 through the aluminum plate body 14;

[0023] See also Figure 6 The outer surface of the heat dissipation fin 13 is coated with a corrosion-resistant coating 15. The number of the heat dissipation fins 13 is several and is evenly distributed. Ventilation holes 7 are opened on the front side of the heat dissipation fin 13. The corrosion-resistant coating 15 is an anodized aluminum film coating, which can improve the corrosion resistance of the heat dissipation fin 13 and extend its service life. By providing the ventilation holes 7, the heat dissipation efficiency is improved, the contact surface with the air is increased, and the heat in the heat dissipation fin 13 is quickly lost.

[0024] See also Figure 4 The positioning mechanism 3 includes a positioning spring 10 and a cover plate 11. The top of the positioning spring 10 is movably connected to the connecting push plate 9. The top of the connecting push plate 9 is welded with a positioning plug plate 8. The top of the positioning plug plate 8 passes through the supporting base plate 5 and the heat dissipation plate 4 in sequence. A sliding opening is opened on the outside of the cover plate 11. The outer side of the connecting push plate 9 passes through the outer side of the cover plate 11. By setting the cover plate 11, it has the function of installation and sealing, which can prevent the positioning spring 10 from falling.

[0025] See also Figure 2 , a cavity is opened on the front side of the interior of the supporting bottom plate 5, and the bottom of the sealing plate 2 is fixedly connected to the base body 1 by a sealing bolt;

[0026] See also Figure 1A slot is provided at the top of the opposite side of the left and right supporting base plates 5, and a mounting hole is provided at the edge of the top of the sealing plate 2. By setting the slot, it has the function of installation guide, which can facilitate the insertion of the aluminum plate body 14 into the interior of the supporting base plate 5.

[0027] When in use, put the battery body 6 into the base body 1 and close the sealing plate 2 for protection. The battery body 6 will generate a lot of heat energy during use. The heat energy is transferred to the aluminum plate body 14 through the bottom of the base body 1, and then transferred to each heat dissipation fin 13, increasing the contact area with the air to achieve rapid heat dissipation. When the base body 1 is deformed and damaged and needs to be replaced, the personnel push the connecting push plates 9 on both sides downward respectively, and the positioning plug plate 8 is removed from the positioning hole 12 and pushed into the cavity inside the supporting bottom plate 5. At this time, the personnel pulls the aluminum plate body 14 forward, and the aluminum plate body 14 is removed from the two sides. Pull it out from the supporting bottom plate 5, so that the heat sink 4 can be removed from the bottom of the base body 1. The personnel only needs to replace the base body 1, and there is no need to replace the heat sink 4 together, which reduces the replacement cost. After the replacement is completed, the personnel pushes the connecting push plate 9 downward again. At this time, the positioning spring 10 is compressed, and then the two sides of the aluminum plate body 14 are respectively inserted into the supporting bottom plates 5 on both sides and pushed in with force. After it is fully pushed in, the connecting push plate 9 is released, and the positioning spring 10 releases its elastic force and pushes the positioning plug plate 8 through the connecting push plate 9 to insert into the positioning hole 12 to fix the aluminum plate body 14. This makes disassembly and assembly more convenient and quick.

[0028] In summary: the power battery base uses a high-efficiency heat dissipation aluminum plate, which solves the problem of being unable to disassemble the heat sink, increasing replacement costs, and poor corrosion resistance through the coordinated use of the base body 1, positioning mechanism 3, heat dissipation plate 4, support bottom plate 5 and corrosion-resistant coating 15.
