Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a water-cooled integrated single battery module. Background Art

[0002] At present, new energy vehicles around the world are developing at an unprecedented speed, and the battery of new energy electric vehicles is the most important part of them. The system integration performance of the battery is the key to determining the battery performance, especially the high and low temperature cycling function under different working conditions. During the charging and discharging process of the battery, a large amount of heat will be generated. If the heat cannot be dissipated in a timely and effective manner, the battery temperature will continue to rise, which will lead to a decline in battery performance and even pose a safety hazard in severe cases. Currently, the mainstream existing battery heat dissipation method is natural heat dissipation, mainly relying on the battery itself to dissipate heat to the surrounding environment. This method can hardly play an effective heat dissipation role when the battery generates more heat, resulting in a continuous increase in the battery temperature, which in turn affects the performance and lifespan of the battery. Summary of the Invention

[0003] Object of the Invention: The object of the present invention is to solve the problem that the mainstream existing battery heat dissipation method is natural heat dissipation and cannot play an effective heat dissipation role.

[0004] Technical Solution: A water-cooled integrated single battery module, including a frame. A plurality of water-cooled plates are fixedly connected together on the front inner surface and the rear inner surface of the frame. On the lower inner surface of the frame and below two adjacent water-cooled plates, U-shaped plug-in plates are fixedly connected together. Between two adjacent water-cooled plates, a battery body is provided, and the lower surfaces of the plurality of battery bodies respectively extend into the interiors of the plurality of U-shaped plug-in plates. Transverse channels are provided in the front and rear of the interior of the frame. Bent channels are integrally formed inside the plurality of water-cooled plates, and both ends of the plurality of bent channels are respectively communicated with the interiors of the two transverse channels.

[0005] Furthermore, a water inlet is provided above the right side of the frame, and a water outlet is provided below the left side of the frame. The left end of the water inlet and the right end of the water outlet are fixedly connected to the two transverse channels respectively.

[0006] Further, sliding grooves are formed in both the left inner side and the right inner side of the U-shaped plug-in board. A sliding plate is slidably connected to the interiors of the two sliding grooves in common. The upper surface of the sliding plate contacts the lower surface of the battery body. A plug-in block is fixedly connected to the lower surface of the sliding plate. A through plug-in groove is formed in common in the lower surfaces of the U-shaped plug-in board and the frame. The lower surface of the plug-in block passes through the plug-in groove. Engagement ports are formed in both the front inner surface and the rear inner surface of the plug-in groove. Activity cavities are formed in both the front inner side and the rear inner side of the plug-in block. Activity plates I are slidably connected to the interiors of the two activity cavities in common. Oblique plates are fixedly connected to the opposite sides of the two activity plates I. The opposite sides of the two oblique plates extend into the interiors of the two engagement ports respectively. A plurality of first springs are fixedly connected to the opposite sides of the two activity plates I and the inner surfaces of the two activity cavities respectively.

[0007] Further, a fixed cross plate is fixedly connected to the upper surface of the frame by bolts. Pressing plates are arranged above the plurality of battery bodies on the lower surface of the fixed cross plate. The lower surfaces of the plurality of pressing plates contact the upper surfaces of the plurality of battery bodies respectively.

[0008] Further, a plurality of guide rods are fixedly connected to both the upper inner surface and the lower inner surface of the interiors of the two sliding grooves in common. The outer side walls of the plurality of guide rods are slidably connected to the interior of the sliding plate. Second springs are arranged on the outer side walls of the plurality of guide rods. The two ends of the plurality of second springs are fixedly connected to the upper surface of the sliding plate and the upper inner surfaces of the two sliding grooves respectively.

[0009] Further, air cavities are formed in the interior of the plug-in block and below the two activity cavities. Activity plates II are slidably connected to the interiors of the air cavities. The upper inner surfaces of the air cavities are communicated with the interiors of the two activity cavities respectively. A pull rod is fixedly connected to the lower surface of the activity plate II. The bottom end of the pull rod extends below the plug-in block and is fixedly connected to a pull plate. A plurality of third springs are fixedly connected to the lower surface of the activity plate II and the lower inner surface of the air cavity.

[0010] Further, heat dissipation grooves are formed above the front inner surface and below the rear inner surface of the interior of the frame.

[0011] Beneficial effects: The coolant flows into the horizontal flow channel from the water inlet and then enters the bent flow channel inside the water-cooling plate. The design of the bent flow channel significantly increases the contact area between the coolant and the battery body, enabling the coolant to more efficiently absorb the heat generated by the battery. Moreover, during the circulation process of the coolant, it can continuously carry away the heat from the battery body and discharge it through the water outlet, achieving an efficient heat exchange process and ensuring that the battery can maintain an appropriate temperature during operation. In addition, the heat dissipation grooves opened on the frame can promote air convection and assist the water-cooling system in heat dissipation, further enhancing the overall heat dissipation effect; The battery body is installed between adjacent water-cooling plates and is limited by a U-shaped plug-in plate. When the battery body is pressed down, the sliding plate drives the plug-in block to insert into the plug-in slot, and the inclined plate is clamped into the clamping opening under the action of spring one, realizing the stable fixation of the battery body. At the same time, the fixed cross plate and the pressing plate on the frame further fix the battery body from above, ensuring that the battery will not shift or shake even in a complex working environment, and guaranteeing the structural stability of the battery assembly; When the battery body needs to be disassembled, by pulling down the corresponding pull plate, due to the pressure change in the air chamber and the movable chamber, the inclined plate is withdrawn from the clamping opening to release the fixation. At this time, the elastic force of spring two will pop up the battery body upward, facilitating the staff to take out the battery, which makes the installation and disassembly process of the battery body simple and fast, improves the maintenance efficiency, and reduces the maintenance cost.

[0014] To make the technical solutions of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments. Example

[0015] like Figures 1-3 As shown, a water-cooled integrated single battery assembly is provided, including a frame 1, a plurality of water-cooling plates 2 are fixedly connected to the inner front surface and the inner rear surface of the frame 1, a U-shaped plug-in plate 3 is fixedly connected to the inner lower surface of the frame 1 and located below two adjacent water-cooling plates 2, a battery body 4 is arranged between two adjacent water-cooling plates 2, the lower surfaces of the plurality of battery bodies 4 extend to the interior of the plurality of U-shaped plug-in plates 3, a transverse flow channel 5 is opened at the inner front and the inner rear of the frame 1, a curved flow channel 6 is integrally formed inside the plurality of water-cooling plates 2, the two ends of the plurality of curved flow channels 6 are respectively connected to the interior of the two transverse flow channels 5, a water inlet 7 is arranged at the upper right side of the frame 1, a water outlet 8 is arranged at the lower left side of the frame 1, and the left end of the water inlet 7 and the right end of the water outlet 8 are respectively fixedly connected to the two transverse flow channels 5; The coolant flows in through the water inlet 7 and enters the rear transverse flow channel 5, and then is diverted to the inside of the curved flow channel 6 integrally formed inside each water-cooling plate 2. The curved design of the curved flow channel 6 greatly increases the heat exchange area between the coolant and the battery body 4. Compared with the straight flow channel, the curved design allows the coolant to flow a longer path in a limited space, and can more fully contact the heat generated by the battery body 4. After the coolant takes away the heat in the curved flow channel 6, it flows into the front transverse flow channel 5 through the other end of the curved flow channel 6, and finally flows out from the water outlet 8 on the left side of the frame 1. The larger heat exchange area enables the coolant to absorb the heat emitted by the battery body 4 more efficiently, improve the heat dissipation efficiency, effectively prevent the battery from overheating and performance degradation during operation, and extend the battery life. At the same time, uniform and efficient heat dissipation helps to maintain the stability of battery performance, avoid performance differences among various parts of the battery due to local overheating, thereby ensuring the reliability and consistency of the entire battery assembly.

[0016] like Figure 1 As shown, heat dissipation grooves 27 are provided above the inner front surface and below the inner rear surface of the frame 1; The two heat dissipation slots 27 can further optimize the heat dissipation performance of the battery assembly, ensure the stable operation of the battery body 4, and extend the service life of the battery. At the same time, it also helps to improve the safety of the entire battery assembly and reduce the risk of failure due to overheating.

[0017] like Figure 3 and Figure 4As shown in the figure, sliding grooves 9 are provided on both the left side and the right side inside the U-shaped plug-in board 3. A sliding board 10 is slidably connected to the inside of the two sliding grooves 9. The upper surface of the sliding board 10 is in contact with the lower surface of the battery body 4. The lower surface of the sliding board 10 is fixedly connected with a plug-in block 11. A through plug-in groove 12 is provided on the lower surface of the U-shaped plug-in board 3 and the lower surface of the frame 1. The lower surface of the plug-in block 11 passes through the plug-in groove 12. Engaging ports 13 are provided on both the front surface and the rear surface inside the plug-in groove 12. Activity cavities 14 are provided in both the front and the rear inside the plug-in block 11. A first activity board 15 is slidably connected to the inside of the two activity cavities 14. Oblique plates 16 are fixedly connected to the opposite sides of the two first activity boards 15. The opposite sides of the two oblique plates 16 respectively extend into the two engaging ports 13. A plurality of first springs 17 are fixedly connected between the opposite sides of the two first activity boards 15 and the inside of the two activity cavities 14 respectively; When assembling the battery body 4 into the inside of the frame 1, the battery body 4 is inserted above the U-shaped plug-in board 3, so that the lower surface of the battery body 4 is in contact with the upper surface of the sliding board 10. Then, the battery body 4 is pressed downward. The sliding board 10 will slide downward in the sliding groove 9. At the same time, the plug-in block 11 will pass through the plug-in groove 12. During the process of the plug-in block 11 passing through the plug-in groove 12, the first activity board 15 in the activity cavity 14 inside the plug-in block 11 will slide into the activity cavity 14 and compress the first spring 17 under the action of the oblique plate 16 being squeezed by the engaging port 13. When the oblique plate 16 reaches a suitable position in the engaging port 13, the elastic force of the first spring 17 will push the first activity board 15 and the oblique plate 16 to reset, so that the oblique plate 16 is clamped into the engaging port 13, thereby realizing the embedding of the battery body 4 into the inside of the frame 1, improving the assembly efficiency and reducing the labor cost.

[0018] As Figure 1 shown in the figure, a fixed cross plate 18 is fixedly connected to the upper surface of the frame 1 through bolts. Pressure plates 19 are provided below the fixed cross plate 18 and above the plurality of battery bodies 4. The lower surfaces of the plurality of pressure plates 19 are respectively in contact with the upper surfaces of the plurality of battery bodies 4; After the plurality of battery bodies 4 are all embedded and installed inside the frame 1, the fixed cross plate 18 is fixedly connected to the upper surface of the frame 1 through bolts, so that the lower surfaces of the plurality of pressure plates 19 are respectively in contact with the upper surfaces of the plurality of battery bodies 4, thereby realizing the fixation above the battery body 4, further enhancing the stability of the battery body 4 inside the frame 1, preventing the battery from shifting and shaking under complex working conditions such as vehicle driving bumps and equipment vibrations, ensuring the integrity of the battery assembly structure, and avoiding faults such as connection loosening and short circuit caused by battery shaking.

[0019] As Figure 3 and Figure 4As shown, air chambers 22 are respectively formed inside the plug-in block 11 and below the two movable chambers 14. A second movable plate 23 is slidably connected inside the air chamber 22. The upper surface inside the air chamber 22 is respectively communicated with the inside of the two movable chambers 14. A pull rod 24 is fixedly connected to the lower surface of the second movable plate 23. The bottom end of the pull rod 24 extends below the plug-in block 11 and is fixedly connected to a pull plate 25. A plurality of third springs 26 are fixedly connected between the lower surface of the second movable plate 23 and the lower surface inside the air chamber 22. The upper surface and the lower surface inside the two sliding grooves 9 are respectively fixedly connected with a plurality of guide rods 20. The outer side walls of the plurality of guide rods 20 are slidably connected to the inside of the sliding plate 10. Spring two 21 are arranged on the outer side walls of the plurality of guide rods 20. The two ends of the plurality of spring two 21 are respectively fixedly connected to the upper surface of the sliding plate 10 and the upper surface inside the two sliding grooves 9. When it is necessary to maintain a certain battery body 4 inside the frame 1, first, remove the upper fixed cross plate 18 to cancel the fixation above the battery body 4. Then, pull down the corresponding pull plate 25. The pull plate 25 drives the pull rod 24 to move downward, thereby causing the second movable plate 23 to slide downward inside the air chamber 22, and at the same time compressing the plurality of third springs 26. Since the upper surface inside the air chamber 22 is communicated with the inside of the movable chamber 14, when the second movable plate 23 moves downward, it will change the air pressure inside the air chamber 22, prompting the first movable plate 15 inside the movable chamber 14 to move inward, compressing the first spring 17, and causing the inclined plate 16 to withdraw from the engaging port 13, releasing the fixation of the battery body 4. At this time, the spring two 21 that was compressed when the battery body 4 was installed will recover its elastic deformation and use its own elastic force to push the sliding plate 10 upward. The sliding plate 10 slides upward along the plurality of guide rods 20, and the battery body 4 can be popped upward and lifted above the frame 1. At this time, the battery body 4 can be conveniently taken out, which greatly improves the disassembly efficiency and saves labor and time costs.

The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
