Description

Technical Field

[0001] This application relates to the technical field of battery cooling, and in particular to a battery pack cooling pipeline. Background Technology

[0002] Battery pack cooling piping is a crucial component in the field of new energy vehicles. Its main function is to control the operating temperature of the battery pack through the circulation of coolant, thereby ensuring that the battery pack operates in a highly efficient and safe manner.

[0003] In the existing technology, when installing cooling pipes for circulating coolant, the required pipes are usually first processed. When installing the pipes, they need to be positioned in the predetermined position by hand or by using tape. Then, the pipes are fixed by screws, welding or other methods, and then connected in sequence.

[0004] The existing installation methods are quite complex, requiring the location of each pipe to be precisely positioned and secured; the operation is cumbersome and the production efficiency is low. Utility Model Content

[0005] To facilitate the installation of cooling pipes and improve production efficiency, this application provides a battery pack cooling pipe system.

[0006] This application provides a battery pack cooling pipeline, which adopts the following technical solution:

[0007] A battery pack cooling pipeline includes a mounting base plate, cooling pipes, a fixing seat, and a fixing component. Several cooling pipes are arranged on the mounting base plate, and each cooling pipe has a connector at both ends for connecting to other cooling pipes. The fixing seat is fixedly arranged on the mounting base plate, and the fixing component can fix the fixing seat to the equipment.

[0008] By adopting the above technical solution, several cooling pipes are mounted on the mounting base plate, and the entire structure is fixed to the equipment using fixing seats and fasteners, thus achieving rapid positioning and installation of the cooling pipes. Compared to the existing technology that requires individual positioning and fixing of each pipe, this solution significantly simplifies the installation process and improves production efficiency.

[0009] Optionally, the fixing base is provided at both ends of the mounting base along the length of the mounting base plate, the fixing member is a fixing bolt, and the fixing base is provided with fixing holes for the fixing bolt to pass through.

[0010] By adopting the above technical solution, the fixing base is set at both ends of the mounting base along the length of the mounting base, which makes the entire cooling pipeline more stable during installation and avoids structural deformation caused by uneven stress. The fixing parts use fixing bolts and fixing holes are opened on the fixing base. This design not only facilitates disassembly and assembly, but also improves installation efficiency, reduces the skill requirements of operators, and ensures the reliability of the connection between the cooling pipeline and the equipment.

[0011] Optionally, the mounting base, cooling pipe, and fixing seat are integrally formed.

[0012] By adopting the above technical solution, the integrated design of mounting base plate, cooling pipe and fixing seat can significantly improve the overall structural strength of battery pack cooling pipe. At the same time, the design simplifies the assembly process, eliminating the need for additional pipe positioning and fixing operations, and greatly improving production efficiency.

[0013] Optionally, a positioning component is also included. The mounting base plate is provided with a plurality of first positioning grooves at intervals for engaging the cooling pipes. The positioning component can fix all the cooling pipes engaged in the first positioning grooves on the mounting base plate.

[0014] By adopting the above technical solution, the first positioning groove is set so that the cooling pipe can be fitted and set on the mounting base plate, thereby improving the stability of fixing the cooling pipe.

[0015] Optionally, the mounting base plate is provided with an arc-shaped positioning strip. One end of the arc-shaped positioning strip is fixed to the mounting base plate and its inner sidewall is connected to the sidewall of the first positioning groove. The other end of the arc-shaped positioning strip has a gap with the mounting base plate. The arc-shaped positioning strip can deform to allow the cooling pipe to enter the first positioning groove.

[0016] By adopting the above technical solution, an arc-shaped positioning strip is provided on the mounting base plate of the cooling pipe, which can quickly position the cooling pipe placed in the first positioning groove, improving installation efficiency and convenience, while ensuring the stability of the cooling pipe in the first positioning groove, thereby improving the reliability of the overall structure.

[0017] Optionally, the positioning component includes a positioning cover and a limiting member. The side wall of the positioning cover is provided with a plurality of second positioning grooves corresponding to the first positioning groove for the cooling pipe to engage. When the positioning cover is closed on the cooling pipe, the limiting member can prevent the positioning cover from falling off the mounting base plate. At this time, the cooling pipe is fixed between the first positioning groove and the second positioning groove.

[0018] By adopting the above technical solution, the cooperation between the positioning cover and the limiting component can effectively fix the cooling pipe and prevent it from loosening or falling off the mounting base plate. The specific effects are as follows: the second positioning groove on the positioning cover and the first positioning groove on the mounting base plate work together to form a double fixation for the cooling pipe, which improves the positional stability of the cooling pipe; the limiting component restricts the positioning cover from falling off the mounting base plate, which further enhances the reliability of the entire structure.

[0019] Optionally, an elastic pad is provided in the second positioning groove.

[0020] By adopting the above technical solution, the elastic pad can increase the friction between the second positioning groove and the cooling pipe, thereby improving the stability of the cooling pipe fixation and reducing the risk of displacement of the cooling pipe under vibration or external force. At the same time, the elastic pad can also play a buffering and protective role for the cooling pipe, preventing the cooling pipe from being damaged due to excessive compression and extending the service life of the cooling pipe.

[0021] Optionally, the limiting member is a limiting bolt, which can pass through the positioning cover and be threaded onto the mounting base plate.

[0022] By adopting the above technical solution and setting limit bolts, a stable connection between the positioning cover and the mounting base plate is achieved, ensuring that the cooling pipe is securely fixed between the first positioning groove and the second positioning groove.

[0023] Optionally, the limiting component includes a limiting block, a control rod, a gripping block, and a limiting spring. A connecting block is provided at the end of the positioning cover. A connecting groove is provided on the mounting base plate for the connecting block to pass through. A sliding groove is provided on the mounting base plate for the limiting block to slide. The sliding groove is connected to the connecting groove and their extension directions are perpendicular to each other. A guide slope is provided at the end of the limiting block facing the connecting groove. When the positioning cover is inserted into the connecting groove, the positioning cover abuts against the guide slope. The control rod is located at the end of the positioning block away from the connecting groove. The gripping block is located at the end of the control rod. The limiting spring is located between the gripping block and the mounting base plate. A limiting groove is provided on the connecting block for the limiting block to insert into. When the limiting block is inserted into the limiting groove, the limiting spring is in a stretched state.

[0024] By adopting the above technical solution, the limiting component adopts a combination design of limiting block, control rod, grip block and limiting spring, which makes the installation and disassembly of the positioning cover more convenient. At the same time, the tension state of the limiting spring ensures the reliable connection between the limiting block and the limiting groove, and improves the reliability of the overall structure.

[0025] In summary, this application includes at least one of the following beneficial effects:

[0026] 1. By fixing several cooling pipes to the mounting base plate and using fasteners and mounting seats to fix the mounting base plate to the equipment, the installation steps of the cooling pipes are simplified, the installation efficiency and positioning accuracy are improved, and the problems of cumbersome operation and low efficiency in the existing technology are effectively solved.

[0027] 2. The cooling pipes and mounting base plate are fixed in a detachable manner, which helps to improve the flexibility of the structure and facilitates the adjustment of the installation requirements of the cooling pipes; at the same time, it is convenient to inspect and maintain the cooling pipes separately.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] Example 1:

[0035] This application discloses a two-channel cooling pipe for a battery pack. (Refer to...) Figure 1 The battery pack cooling pipe 2 includes a mounting base plate 1, cooling pipes 2, fixing seats 3, and fixing components 4. The mounting base plate 1 is a long strip of metal plate, which mainly serves to position and support the device. Several cooling pipes 2 are provided on the mounting base plate 1. Specifically, the cooling pipes 2 extend along the length of the mounting base plate 1, and all cooling pipes 2 are spaced apart along the width of the mounting base plate 1. The cooling pipes 2 have connectors at both ends for connecting to other cooling pipes 2. The connectors are preferably integrally formed with the cooling pipes 2. The fixing seats 3 are fixedly provided on the mounting base plate 1, and preferably are provided at both ends of the mounting base plate 1. The fixing components 4 can fix the fixing seats 3 to the device.

[0036] With this design, multiple cooling pipes 2 are first fixed to the mounting base plate 1. The mounting base plate 1 is then fixed to the equipment using the fixing seat 3, thus fixing all the cooling pipes 2 on the mounting base plate 1 at once. This method is not only convenient and quick to install, avoiding the tediousness of positioning each cooling pipe 2 in the traditional installation method, but also improves installation efficiency. At the same time, by simply presetting the fixing position of the fixing seat 3, the installation of the cooling pipes 2 can be guaranteed to be in place, which can also improve the accuracy and standardization of the installation.

[0037] In this embodiment, the fixing member 4 is preferably a fixing bolt, and the fixing seat 3 can be set as a rectangular seat. The fixing seat 3 has fixing holes for the fixing bolt to pass through. At the same time, the corresponding position on the equipment can be preset with threaded holes. During installation, the mounting base plate 1 is placed in the predetermined position, and the fixing seat 3 and the mounting base plate 1 are immediately fixed to the equipment by fixing bolts, thereby fixing several cooling pipes 2 on the mounting base plate 1.

[0038] In this embodiment, the mounting base 1, cooling pipe 2, and fixing seat 3 are integrally formed and all made of metal, ensuring a certain strength while also ensuring the thermal conductivity of the cooling pipe 2. In this embodiment, the cooling pipe 2 can be symmetrically embedded in the mounting base 1, which facilitates better contact between the cooling pipe 2 and the battery when the mounting base 1 is fixed to the equipment.

[0039] The implementation principle of this embodiment is as follows: by fixing multiple cooling pipes 2 to the mounting base plate 1, and then fixing the mounting base plate 1 to the equipment with fixing bolts, the installation and fixing of multiple cooling pipes 2 can be quickly realized, simplifying the installation process and improving installation efficiency. At the same time, the cooling pipes 2 and the mounting plate are integrally molded, which can further improve installation efficiency and ensure installation stability.

[0040] Example 2:

[0041] The difference between this embodiment and Embodiment 1 is that the cooling pipe 2 can be detachably fixed to the mounting base plate 1 by means of the positioning component 5. This installation method retains the advantage of quickly installing the cooling pipe 2 by means of the mounting base plate 1. At the same time, it can also adjust the number of cooling pipes 2 fixed on each mounting base plate 1, and facilitates quick inspection and maintenance of each cooling pipe 2 in the later maintenance.

[0042] Reference Figure 2 and Figure 3In this embodiment, the mounting base plate 1 is also a rectangular metal plate. Multiple first positioning grooves 11 are recessed to one side of the mounting base plate 1 to engage the cooling pipe 2. The inner wall of each first positioning groove 11 corresponds to the outer wall of the cooling pipe 2, thus initially positioning the cooling pipe 2 on the mounting base plate 1. It should be noted that, to ensure efficient heat transfer between the cooling pipe 2 and the battery, the mounting base plate 1 is made of metal, and the wall thickness corresponding to the first positioning grooves 11 is relatively thin.

[0043] Reference Figure 2 and Figure 3 In this embodiment, an arc-shaped positioning strip 12 is also provided on the mounting base plate 1. The arc-shaped positioning strip 12 can be fixed to the side wall of the mounting base plate 1 by welding or integral molding. The arc-shaped positioning strip 12 bends towards the first positioning groove 11, and its inner side wall is connected to the inner side wall of the first positioning groove 11. At the same time, there is a gap between the end of the arc-shaped positioning strip 12 and the mounting base plate 1, which can deform to allow the cooling pipe 2 to enter the first positioning groove 11. By adding the arc-shaped strip, the cooling pipe 2 can be quickly clamped, preventing the cooling pipe 2 from falling out and improving the convenience of installation. Preferably, the arc-shaped positioning strip 12 can be provided at both ends of the mounting base plate 1 to improve the positioning effect.

[0044] Reference Figure 2 and Figure 3 In this embodiment, the positioning component 5 includes a positioning cover 51 and a limiting member 52. The positioning cover 51 is a rectangular plate that extends along the length of the mounting base plate 1. A plurality of second positioning grooves 511 are provided on the positioning cover 51, which correspond to the first positioning grooves 11 and are used to further engage and fix the cooling pipe 2. The limiting member 52 is used to fix the positioning cover 51 on the mounting base plate 1, thereby fixing the cooling pipe 2 through the positioning cover 51.

[0045] Alternatively, an elastic pad 6 can be provided in the second groove. The elastic pad 6 can be made of silicone material, which has good cushioning performance to prevent the cooling pipe 2 from being damaged by vibration during use, and can also improve the fixing effect of the cooling pipe 2.

[0046] In an optional embodiment, the limiting member 52 can be a limiting bolt (not shown in the figure). The limiting bolt is preferably provided at both ends of the positioning rod. The limiting bolt passes through the positioning cover 51 and is threadedly connected to the mounting base plate 1, so that the positioning cover 51 and the cooling pipe 2 can be fixed to the mounting base plate 1.

[0047] Reference Figure 3 and Figure 4In another optional embodiment, the limiting member 52 includes a limiting block 521, a control rod 522, a gripping block 523, and a limiting spring 524. The upper and lower ends of the positioning cover 51 are fixed with connecting blocks 512, which extend toward the mounting base plate 1. The mounting base plate 1 has a connecting groove 13 for the connecting block 512 to pass through, and the connecting groove 13 can be located at the center of the mounting plate. The limiting block 521 is slidably disposed on the mounting base plate 1, and the connecting block 512 has a limiting groove 513 for the limiting block 521 to insert into. When the connecting block 512 is inserted into the connecting groove 13 and the limiting block 521 is inserted into the limiting groove 513, the connecting block 512 can be prevented from coming out of the connecting groove 13, that is, the positioning cover 51 can be fixed to the mounting base plate 1.

[0048] Specifically, the mounting base plate 1 has a sliding groove 14 for the sliding of the limiting block 521. The sliding groove 14 is connected to the connecting groove 13 and the extension directions are perpendicular to each other. The limiting block 521 is slidably disposed in the sliding groove 14, and a guide slope is provided at the end of the limiting block 521 facing the connecting groove 13. The control rod 522 is fixed to the end of the limiting block 521 away from the connecting groove 13, the gripping block 523 is fixed to the end of the control rod 522, and the limiting spring 524 is connected between the gripping block 523 and the mounting base plate 1. When the limiting block 521 is inserted into the limiting groove 513, the limiting spring 524 is in a stretched state. When the positioning cover 51 is inserted into the connecting groove 13, the positioning cover 51 abuts against the guide slope, causing the limiting block 521 to move upward, allowing the connecting block 512 to be smoothly inserted into the connecting groove 13. After the connecting block 512 is in place, the limiting block 521 can be inserted into the limiting groove 513 under the action of the limiting spring 524, thereby fixing the positioning cover 51. When it is necessary to remove the positioning cover 51, simply move the limiting block 521 upward by holding the block 523 to unlock the limiting member 52 and remove the positioning cover 51.

[0049] The implementation principle of this embodiment is as follows: In use, first, place the required number of cooling pipes 2 into the first positioning groove 11 according to the needs, and position them using the arc-shaped positioning strip 12; then, cover the cooling pipes 2 with the positioning cover 51, and fix the positioning cover 51 to the mounting base plate 1 using the limiting member 52, that is, fix the cooling pipes 2 to the mounting base plate 1; finally, fix the mounting base plate 1 to the equipment. When it is necessary to inspect the cooling pipes 2, first unlock the limiting member 52, then remove the positioning cover, and the corresponding cooling pipe 2 can be removed.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
