Description

Technical Field

[0001] This utility model relates to the field of energy storage battery pack enclosure technology, specifically an integrated steel-aluminum hybrid energy storage enclosure. Background Technology

[0002] A battery pack typically refers to a collection of multiple battery cells assembled together to provide power. The battery pack housing is the main load-bearing component of the battery pack, and its structure and layout directly affect the battery pack's lifespan. Only when the housing is statically and dynamically stable (rigidity, modal characteristics, etc.) can the battery power system operate smoothly. Currently, most energy storage battery pack housings are made of aluminum alloy, but aluminum alloy materials are relatively expensive, so the amount of capital required for mass production of energy storage battery pack housings is relatively large. Utility Model Content

[0003] To address the problems mentioned in the background section, the present invention aims to provide an integrated steel-aluminum hybrid energy storage enclosure, which has the advantages of both reducing costs and improving overall structural performance. It solves the problem that most energy storage battery pack enclosures currently use aluminum alloys, which are expensive and therefore require a large amount of capital for mass production.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an integrated steel-aluminum hybrid energy storage tank, comprising a flat plate, a flow channel plate, a water connector, and a module crossbeam. The bottom of the module crossbeam is fixedly connected to the left and right sides of the top of the flat plate. The water connector is fixedly installed on both sides of the left side of the top of the flat plate and is connected to the flat plate. The bottom of the flow channel plate is provided with two reinforcing ribs. The front and rear sides of the reinforcing ribs are fixedly connected to square tubes. The inner side of the square tubes is provided with square tubes. The two ends of the square tubes are fixedly connected to the right side of the inner side of the square tubes. The inner side of the square tubes is provided with reinforcing ribs. The front and rear sides of the reinforcing ribs are fixedly connected to the left side of the inner side of the square tubes. The materials of the reinforcing ribs, the reinforcing ribs, the square tubes are all steel, and the materials of the flat plate, the flow channel plate, and the water connector are all aluminum alloy.

[0005] As a preferred embodiment of this utility model, the top of the plate is provided with an M5 rivet nut. Several M5 rivet nuts are provided and distributed in a rectangular, equidistant pattern. The end of each M5 rivet nut near the second reinforcing rib passes through the plate, the flow channel plate, and the second reinforcing rib in sequence, extending to the bottom of the second reinforcing rib. The M5 rivet nut is threadedly connected to the plate, the flow channel plate, and the second reinforcing rib. The end of each M5 rivet nut near the first square tube passes through the plate, the flow channel plate, and the first square tube in sequence, extending to the bottom of the first square tube. The M5 rivet nut is threadedly connected to the plate, the flow channel plate, and the first square tube. The end of each M5 rivet nut near the second square tube passes through the plate, the flow channel plate, and the second square tube in sequence, extending to the bottom of the second square tube. The M5 rivet nut is threadedly connected to the plate, the flow channel plate, and the second square tube.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0007] 1. This utility model, by setting up square tube one, square tube two, reinforcing rib one, and reinforcing rib two, first assembles the flat plate, flow channel plate, water connector, and module crossbeam and then places them in a furnace for brazing. After brazing, a water-cooled plate is formed. Then, square tube one, square tube two, and reinforcing rib one and reinforcing rib two are assembled into a reinforcing rib frame. The splicing points of each part are connected by welding. The water-cooled plate is made of aluminum alloy, which has the characteristics of good heat dissipation and corrosion resistance. The reinforcing rib frame is made of steel structure. Due to the high strength of steel, the overall load-bearing, vibration, drop, and extrusion performance can be improved. At the same time, the cost of steel is relatively low, which can reduce the overall cost. This solves the problem that most energy storage battery pack boxes are made of aluminum alloy, which is expensive and requires a large amount of capital for mass production of energy storage battery pack boxes. It achieves the effect of both reducing costs and improving the overall structural performance.

[0008] 2. By setting M5 rivet nuts, this utility model can assemble and fix the water-cooled plate formed by the assembly and brazing of the flat plate, flow channel plate, water connector and module crossbeam, and the reinforcing frame formed by the assembly of square tube one, square tube two and reinforcing rib one and reinforcing rib two.

The end of the M5 rivet nut 9 near the second reinforcing rib 6 passes through the plate 1, the flow channel plate 2 and the second reinforcing rib 6 in sequence and extends to the bottom of the second reinforcing rib 6. The M5 rivet nut 9 is threadedly connected to the plate 1, the flow channel plate 2 and the second reinforcing rib 6. The end of the M5 rivet nut 9 near the first square tube 3 passes through the plate 1, the flow channel plate 2 and the first square tube 3 in sequence and extends to the bottom of the first square tube 3.

The M5 rivet nut 9 is threadedly connected to the plate 1, the flow channel plate 2 and the second square tube 4.

[0017] As a technical optimization of this utility model, by setting M5 rivet nuts 9, the water-cooled plate formed by assembling and brazing the flat plate 1, flow channel plate 2, water connector 7 and module crossbeam 8 can be assembled and fixed with the reinforcing frame formed by assembling square tube 1 3, square tube 2 4 and reinforcing rib 1 5 and reinforcing rib 2 6.

[0018] The working principle and usage process of this utility model are as follows: First, the flat plate 1, flow channel plate 2, water connector 7, and module crossbeam 8 are assembled and placed in a furnace for brazing. After brazing, a water-cooled plate is formed. Next, square tube 1 (3), square tube 2 (4), and reinforcing rib 1 (5) and reinforcing rib 2 (6) are assembled into a reinforcing rib frame. The parts are connected by welding at their joints. The water-cooled plate is made of aluminum alloy, which has good heat dissipation and corrosion resistance. The reinforcing rib frame is made of steel, which has high strength and improves overall load-bearing capacity. It has excellent resistance to load, vibration, drop, and extrusion. At the same time, steel has a lower cost, which can reduce the overall cost. Next, the water-cooled plate and the reinforcing frame are assembled and fixed with M5 rivet nuts 9 around the perimeter. The surfaces of the water-cooled plate and the reinforcing frame in contact are glued together. Finally, after the above assembly is completed, M6 rivet nuts are used to form an integrated steel-aluminum hybrid lower box. At the same time, the steel-aluminum hybrid box can flexibly adjust the ratio of steel and aluminum according to different specifications of energy storage boxes, thereby achieving the effect of cost reduction and efficiency improvement.

[0019] In summary, this integrated steel-aluminum hybrid energy storage enclosure, through the installation of square tube 1 (3), square tube 2 (4), reinforcing rib 1 (5), and reinforcing rib 2 (6), firstly, the flat plate 1, flow channel plate 2, water connector 7, and module crossbeam 8 are assembled and then brazed in a furnace, forming a water-cooled plate. Next, square tube 1 (3), square tube 2 (4), and reinforcing rib 1 (5) and reinforcing rib 2 (6) are assembled into a reinforcing rib frame. The components are connected by welding at their joints. The water-cooled plate is made of aluminum alloy, which has excellent heat dissipation and corrosion resistance. The reinforcing rib frame is made of steel. Due to the high strength of steel, the overall load-bearing, vibration, drop, and extrusion performance is improved. At the same time, steel has a lower cost, reducing the overall cost. This solves the problem that most energy storage battery pack enclosures currently use aluminum alloy, which is expensive, thus requiring a large amount of capital for mass production.
