[0023] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] like Figure 1-3 As shown, the aluminum alloy integrated liquid cooling integrated energy storage box 100 in one embodiment of the utility model includes a bottom plate 10, a side plate 20 and a cooling pipe 30. The side plate 20 surrounds the edge of the bottom plate 10 and forms a storage space for placing batteries with the bottom plate 10. The cooling pipe 30 is buried in the bottom plate 20, and its water inlet 31 and water outlet are exposed from the bottom plate 20.

[0025] Traditional battery boxes are generally made by welding profiles, and cooling water channels are also made by welding. Due to the large-area welding process, it is inevitable that some parts are not welded properly or cracks appear, resulting in poor sealing, which ultimately leads to defective products.

[0026] To solve this problem, the aluminum alloy integrated liquid-cooled integrated energy storage box 100 in this embodiment buries the cooling pipe 30 in the bottom plate 10. When casting the bottom plate 10, the cooling pipe 30 is placed in the mold, and then the molten liquid is injected into the mold and waited for cooling and solidification. Since the cooling pipe 30 and the bottom plate 10 are integrally cast and formed without any welding operation, the overall sealing is high, which greatly avoids the problem of coolant leakage, and the overall yield and safety are high.

[0027] It is easy to imagine that in order to prevent the cooling pipe 30 from melting during the casting process, its melting point needs to be higher than the melting points of the bottom plate 10 and the side plate 20. In this embodiment, the cooling pipe 30 is made of steel, and its melting point is about 1500°C, while the bottom plate 10 and the side plate 20 are made of aluminum, and its melting point is only about 660°C, so the cooling pipe 30 will not melt in the aluminum liquid during the casting process.

[0028] In this embodiment, the cooling pipe 30 is formed by bending a steel water pipe, thereby avoiding welding operations. The entire cooling pipe 30 is formed in one piece, has no welding points, and is smoother as a whole. There will be no coolant overflow due to cracks in welding or inadequate welding.

[0029] like Figure 2 As shown, the cooling pipe 30 is formed with a plurality of bends to cover as much of the bottom plate 10 as possible, provide more cooling area, and improve the cooling effect.

[0030] Furthermore, the cooling pipe 30 is flat and has a rectangular cross-section, so the entire cooling pipe 30 is projected onto the plane of the base plate 10 with a larger area, resulting in a better cooling effect. This helps reduce the thickness of the base plate 10 and lowers the overall quality and cost.

[0031] In this embodiment, the water inlet 31 and the water outlet 32 ​​are arranged on the same side of the bottom plate 10 for water injection and water extraction. Of course, the two water inlets can also be arranged on different sides according to actual conditions, and this embodiment is not limited thereto.

[0032] Preferably, a plurality of reinforcing ribs 21 are arranged in an array on each side panel 20 to improve the overall rigidity and prevent deformation.

[0033] It can be imagined that the cooling pipe 30 and the bottom plate 10 are cast as one piece, and the bottom plate 10 and the side plate 20 can also be made in this way, so that the entire box is also integrally formed, with higher stability, especially when a three-dimensional cooling mechanism is used, it has better sealing.

[0034] Preferably, a plurality of holes 11 are arranged in an array on the bottom plate 10 , and each hole 11 extends to the internal cooling pipe 30 , respectively, for releasing pressure and preventing the bottom plate 10 from deforming.

[0035] Furthermore, the water inlet 31 and the water outlet 32 ​​are located outside the accommodating space to prevent the internal space from being occupied, improve space utilization, and facilitate the connection of water pipes.

[0036] Preferably, in order to prevent cooling water from splashing onto the internal battery and causing safety problems when the water is turned on or off, in this embodiment, the height of the side panel 20 on one side of the water inlet 31 and the water outlet 32 ​​is greater than the height of the remaining other side panels 20 to form a barrier to the cooling water and improve safety.

[0037] This embodiment also provides a method for manufacturing the aluminum alloy integrated liquid-cooled integrated energy storage box 100, comprising steps S1-S3:

[0038] In step S1, a water pipe is provided and the water pipe is bent multiple times.

[0039] Specifically, a steel water pipe is taken and bent multiple times according to the shape of the bottom plate 10 to form the final cooling pipe 30 .

[0040] In step S2, the bent water pipe is placed in a casting mold, and aluminum liquid is poured into the casting mold. The casting mold includes a cavity for forming a bottom plate 10 and a side plate 20, and finally solidifies to form the aluminum alloy integrated liquid-cooled integrated energy storage box 100.

[0041] Specifically, the cooling pipe 30 is placed in a casting mold, which includes a cavity for forming a base plate 10 and a side plate 20. The cooling pipe 30 is placed in the cavity of the base plate 10, and then molten aluminum is poured into the mold. After cooling and solidification, the final aluminum alloy integrated liquid-cooled integrated energy storage box 100 is formed.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
