Description

Technical Field

[0001] This application relates to the field of battery thermal management technology, and in particular to a battery pack structure and vehicle. Background Technology

[0002] With the continuous development of pure electric and hybrid technologies, battery packs are often constructed using series and parallel connections with additional modules to meet the vehicle's performance requirements for voltage, current, and capacity. However, the large number of cells generates a significant amount of heat during charging and discharging, which can easily cause the battery pack to overheat. This not only affects the battery pack's cycle life but may even lead to an explosion. Therefore, the heat dissipation performance of the battery pack is crucial.

[0003] Common battery pack cooling methods include air cooling, water cooling, or a combination of both. For battery packs using air cooling technology, since the battery modules are installed inside the battery pack casing, it is difficult to adequately cool the internal cells for safety reasons, resulting in poor heat dissipation performance. Utility Model Content

[0004] In view of this, this application aims to propose a battery pack structure and vehicle to solve the problem that it is difficult to adequately cool the core at the center of the battery pack when it is air-cooled.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0006] The first aspect of this application provides a battery pack structure, including:

[0007] Mounting bracket;

[0008] Multiple mounting sleeves are provided inside the mounting bracket. Each mounting sleeve has a cavity inside, and each mounting sleeve has openings at both ends in the length direction so that the cavity communicates with the outside.

[0009] A battery module is disposed inside the cavity and its shape matches the cavity; the battery module is hollow inside and its two ends in the length direction are connected to the outside, so that a heat dissipation channel is formed in the center of the battery module;

[0010] A heat dissipation mechanism is mounted on the mounting bracket and corresponds to the heat dissipation air duct.

[0011] Optionally, the heat dissipation mechanism includes:

[0012] Multiple fan mounting brackets are mounted on the mounting brackets and correspond one-to-one with the heat dissipation air ducts of each of the battery modules;

[0013] Multiple fans are respectively installed inside each of the aforementioned fan mounting brackets.

[0014] Optionally, each of the aforementioned fan mounting brackets is integrated into one unit.

[0015] Optionally, the mounting bracket is provided with cover plates at the openings at both ends of the mounting sleeve, and the cover plates are provided with through holes that match the heat dissipation duct.

[0016] Optionally, the heat dissipation mechanism further includes multiple heat-conducting components, which are respectively disposed inside the heat dissipation duct of each battery module, and the shape of the heat-conducting components matches the shape of the heat dissipation duct, and the heat-conducting components are in contact with the wall of the battery module.

[0017] Optionally, the length of the heat-conducting component is the same as the length of the battery module, the heat-conducting component is a tubular shape with an internal hollow structure and open ends, and the heat-conducting component is provided with multiple heat dissipation fins inside.

[0018] Optionally, each of the heat dissipation fins is evenly distributed in the circumferential direction of the heat-conducting component, and the length direction of the heat dissipation fins is consistent with the length direction of the heat-conducting component.

[0019] Optionally, the inner wall of the battery module is provided with a connecting groove, and the heat-conducting component is provided with a protrusion that matches the connecting groove.

[0020] Optionally, the cross-section of the cavity inside the mounting sleeve and the battery module are circular or polygonal.

[0021] A second aspect of this application provides a vehicle that includes the battery pack structure provided in the first aspect.

[0022] Compared with the prior art, the battery pack structure and vehicle described in this application have the following advantages:

[0023] By employing a hollow internal structure with both ends open to the outside to form a heat dissipation channel, the battery module significantly increases the contact area with air. Heat can be quickly dissipated through the heat dissipation channel, effectively solving the problem of low heat dissipation efficiency in existing air-cooled battery packs. The heat dissipation channel runs through the center of the battery module, directly dissipating heat from core heat-generating components such as the internal cells, overcoming the difficulty of traditional air-cooled battery packs in adequately cooling the internal cells.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figure 1 As shown, the first aspect of this application provides a battery pack structure, including:

[0033] Mounting bracket 1;

[0034] Multiple mounting sleeves 2 are provided inside the mounting bracket 1. Each mounting sleeve 2 has a cavity 21 inside, and each mounting sleeve 2 has openings at both ends in the length direction so that the cavity 21 communicates with the outside.

[0035] The battery module 3 is disposed inside the cavity 21 and its shape matches the cavity 21; the battery module 3 is hollow inside and its two ends in the length direction are connected to the outside, so that a heat dissipation channel is formed in the center of the battery module 3.

[0036] The heat dissipation mechanism 4 is mounted on the mounting bracket 1 and corresponds to the heat dissipation air duct.

[0037] Mounting bracket 1 provides a basic support frame for the entire battery pack structure, bearing and securing other components to ensure the stability and integrity of the battery pack structure. It ensures that the components maintain relative positional stability under various operating conditions, such as vehicle operation, preventing component displacement or loosening, and provides a reliable mounting base for battery modules 3, ensuring the normal operation of the battery pack.

[0038] The mounting sleeve 2 is installed inside the mounting bracket. Its internal cavity 21 accommodates the battery module 3, and the open design at both ends allows the cavity 21 to communicate with the outside, providing a channel for heat dissipation. Through a reasonable layout and structural design, it positions and protects the battery module 3, while the cavity 21, communicating with the outside, creates conditions for subsequent heat dissipation, facilitating heat dissipation and air circulation. The cavity 21, as the installation space for the battery module 3, is shaped to match the battery module 3, ensuring accurate installation and stable placement within it. Providing suitable housing space for the battery module 3 allows it to maintain a relatively stable state during operation, reducing the impact of shaking and other factors on the performance and lifespan of the battery module 3.

[0039] Battery module 3 is the core component of the battery pack, responsible for storing and releasing electrical energy. It can be designed in a cylindrical shape, with a hollow interior and both ends open to the outside, forming heat dissipation channels. This structure significantly increases the surface area in contact with air. Compared to traditional battery modules, heat can be transferred more quickly from the inside of battery module 3 to the air through the walls of the heat dissipation channels, effectively improving heat dissipation efficiency and solving the problem of low heat dissipation efficiency in existing air-cooled battery packs. The presence of the heat dissipation channels allows heat to be quickly expelled through air convection, reducing the internal temperature of battery module 3. When battery module 3 generates heat during operation, hot air can rise naturally and be exhausted from both ends of the heat dissipation channels, while cool air enters from the outside to replenish it, forming a good heat exchange cycle and effectively preventing heat accumulation.

[0040] The heat dissipation duct runs through the center of battery module 3, directly dissipating heat from the core heat-generating components such as the battery cells inside the battery module 3. Traditional air-cooled battery packs struggle to adequately cool the internal battery cells, while the heat dissipation duct allows cool air to directly contact the heat generated by the battery cells, carrying the heat away and effectively solving the current predicament of air-cooled battery packs being unable to effectively dissipate heat from the inside of the battery module.

[0041] The heat dissipation mechanism 4 is mounted on the mounting bracket and corresponds to the heat dissipation duct of the battery module 3. It accelerates heat dissipation through forced airflow and other methods. It actively promotes airflow in the heat dissipation duct, enhances the heat dissipation effect, effectively reduces the temperature of the battery module, prevents the battery pack from degrading in performance or malfunctioning due to overheating, and ensures that the battery pack operates within a suitable temperature range.

[0042] like Figure 1 and Figure 3 As shown, the heat dissipation mechanism 4 further includes: multiple fan mounting brackets 41, which are mounted on the mounting bracket 1 and correspond one-to-one with the heat dissipation air ducts of each battery module 3; and multiple fans 42, which are respectively disposed inside each fan mounting bracket 41.

[0043] The fan mounting bracket 41 has an internal hollow design to accommodate the fan 42. The fan mounting bracket 41 is connected to the mounting bracket 1 by screws, and each fan mounting bracket 41 faces one battery module 3, ensuring that the fan 42 inside the fan mounting bracket 41 is directly aligned with the heat dissipation duct of the battery module 3. This ensures that the cooling airflow is precisely directed to the heat dissipation duct of the battery module 3. It allows cool air to directly enter the heat dissipation duct and hot air to be smoothly exhausted, improving heat dissipation efficiency, avoiding ineffective airflow diffusion, and guaranteeing effective heat dissipation for the battery module 3.

[0044] By configuring multiple fans 42 corresponding to multiple battery modules 3, the operating status of each fan 42 can be flexibly controlled according to the actual heat generation of the battery modules 3. For example, when some battery modules 3 generate a lot of heat, the speed of the corresponding fan 42 can be increased individually to achieve differentiated heat dissipation for different battery modules 3, better adapt to the heat dissipation requirements of the battery pack under different operating conditions, and improve the overall heat dissipation performance and reliability of the battery pack.

[0045] The fan mounting bracket 41 is connected to the mounting bracket 1 by screws. This connection method ensures the stable installation of the fan mounting bracket 41 on the mounting bracket 1, and also facilitates the disassembly and replacement of the fan mounting bracket 41 and the fan 42. When the heat dissipation mechanism needs to be repaired or parts replaced, it can be done conveniently and quickly, reducing maintenance costs and difficulty, while also ensuring the stability of the entire battery pack structure during daily use and maintenance.

[0046] Furthermore, each fan mounting bracket 41 is integrated into one unit, meaning that the fan mounting brackets 41 on the same side are connected to each other as one unit.

[0047] The integrated fan mounting bracket 41 eliminates gaps and weak points between components, resulting in a more robust overall structure. During vehicle operation, it better resists external forces such as vibration and impact, reducing the risk of fan 42 displacement or damage due to bracket deformation or loosening. This ensures the stability and reliability of the heat dissipation mechanism 4 and guarantees the continuous and effective heat dissipation of the battery module 3.

[0048] In terms of manufacturing, the one-piece molding process simplifies the production process, reduces the number of parts, and lowers production costs. Meanwhile, during installation, the integrated fan mounting bracket 41 only requires a single installation operation to secure it to the mounting bracket 1, which is simpler and faster than installing multiple separate components one by one, improving production efficiency and reducing potential installation errors and problems.

[0049] Furthermore, in an optional embodiment, the heat dissipation mechanism 4 can also use a liquid-cooled heat dissipation module instead of a fan-based heat dissipation mechanism. The liquid-cooled heat dissipation module includes components such as liquid-cooled pipes, coolant, a coolant pump, and a radiator. The liquid-cooled pipes can be designed in a serpentine or spiral shape to increase the contact area with the battery module 3. The pipes are laid near the heat dissipation ducts of the battery module 3 or directly attached to the outer casing of the battery module 3. The coolant pump drives the coolant to circulate within the pipes, while the radiator is responsible for cooling the coolant that has absorbed heat from the battery module 3.

[0050] Furthermore, the mounting bracket 1 has cover plates 11 at both ends of the mounting sleeve 2, and the cover plates 11 have through holes 12 that match the heat dissipation airflow. The cover plates 11 are positioned between the fan mounting bracket 41 and the mounting bracket 1, and are connected to the mounting bracket 1 by screws. During connection, they can be matched with the fan mounting bracket 41, allowing the fan mounting bracket 41 and the cover plates 11 to be installed using the same one or more screws. That is, screw holes are provided on the mounting bracket 1, and threaded through holes are provided on the cover plates 11 and the fan mounting bracket 41 to match the screw holes. During installation, first place the cover plates 11 in the corresponding positions, aligning the through holes on the cover plates 11 with the screw holes on the mounting bracket 1. Then, fit the fan mounting bracket 41 against the cover plates 11, aligning the through holes on the fan mounting bracket 41 with the through holes on the cover plates 11. Finally, insert the screws to install the cover plates 11 and the fan mounting bracket 41 together onto the mounting bracket 1.

[0051] The cover plate 11 is mainly used to seal the opening of the cavity 21 of the mounting sleeve 2, effectively fixing the battery module 3 and preventing it from sliding out of the cavity 21 due to vibration or bumps during vehicle operation. This ensures that the battery module 3 is always in the correct installation position. By preventing the battery module 3 from shaking or shifting within the cavity 21, it avoids impacting the fan mounting bracket 41 or other surrounding components when the vehicle vibrates. This reduces the risk of damage to the battery module 3 due to collisions.

[0052] The cover plate 11 has through holes 12 that match the heat dissipation duct, providing a clear flow path for the heat dissipation airflow. This ensures that the airflow generated by the fan 42 can accurately pass through the heat dissipation duct without being obstructed by the cover plate 11, thus preventing turbulence or backflow. This reasonable airflow guidance helps improve heat dissipation efficiency, allowing the heat generated by the battery module 3 to be dissipated more smoothly.

[0053] The cover plate 11 and the fan mounting bracket 41 can share screws for installation, simplifying the installation structure. This reduces the number of screws and mounting holes required, lowering installation complexity and component management costs. Simultaneously, this shared screw installation method allows the installation processes of the cover plate 11 and the fan mounting bracket 41 to be interconnected and coordinated, improving installation accuracy and efficiency, reducing adjustment and positioning time during installation, facilitating rapid assembly on the production line, and increasing battery pack production efficiency.

[0054] During installation, the cover plate 11 and the fan mounting bracket 41 are tightly fixed together with the mounting bracket 1 by a common screw connection, forming a mutually supportive and synergistic integrated structure. This structure enhances the connection strength between the mounting bracket 1, the cover plate 11, and the fan mounting bracket 41, improves the vibration resistance and stability of the entire cooling system and battery pack structure under vehicle operating conditions, and reduces the possibility of components loosening or being damaged due to long-term vibration.

[0055] like Figure 1 and Figure 2 As shown, the heat dissipation mechanism 4 further includes multiple heat-conducting components 43, which are respectively disposed inside the heat dissipation air duct of each battery module 3, and the shape of the heat-conducting component 43 matches the shape of the heat dissipation air duct, and the heat-conducting component 43 is in contact with the wall of the battery module 3.

[0056] The heat-conducting component 43 is attached to the wall of the battery module 3. Its excellent thermal conductivity can quickly conduct the heat generated by the cells inside the battery module 3 to the air in the heat dissipation duct. Compared with relying solely on the natural heat exchange between the battery module 3 casing and the air, the heat-conducting component 43 greatly increases the speed and efficiency of heat transfer, allowing heat to be transferred more quickly from the cells to the heat dissipation duct and then expelled from the battery pack, effectively reducing the temperature of the battery module 3 and improving the heat dissipation effect.

[0057] During the charging and discharging process of battery module 3, temperature changes generate thermal stress. The presence of heat-conducting component 43 can distribute heat more evenly, reducing thermal stress concentration caused by uneven temperature. This helps protect the structural integrity of battery module 3, preventing deformation and cracking of the battery module 3 casing due to excessive thermal stress, and reducing the risk of failure caused by structural damage to battery module 3.

[0058] The heat-conducting component 43 is tightly fitted to the wall of the battery module 3, providing support and reinforcement to the outer shell of the battery module 3 to a certain extent. When vibration or impact occurs during vehicle operation, the heat-conducting component 43 can help disperse external forces, reduce the direct impact on the outer shell of the battery module 3, further protect the safety of the internal cells of the battery module 3, and improve the reliability of the battery pack under complex operating conditions.

[0059] Furthermore, the length of the heat-conducting component 43 is the same as that of the battery module 3. The heat-conducting component 43 is a tubular structure with an internal hollow core and open ends. Multiple heat dissipation fins 44 are provided inside the heat-conducting component 43.

[0060] The length of the heat-conducting component 43 is the same as the length of the battery module 3, ensuring efficient heat conduction along the entire length of the battery module 3. This makes full use of the space of the battery module 3, allowing the heat-conducting component 43 to fully contact the heat generated by the internal cells of the battery module 3, leaving no dead corners for heat dissipation, thereby maximizing the efficiency of heat collection and conduction, and ensuring a uniform decrease in the overall temperature of the battery module 3.

[0061] Multiple heat dissipation fins 44 inside the heat-conducting component 43 further increase the heat dissipation surface area. When hot air flows inside the pipe, the heat dissipation fins 44 increase the contact opportunity between the air and the heat-conducting component 43, allowing heat to be transferred to the air more quickly. The heat dissipation fins 44 can also disrupt airflow, enhancing air turbulence and promoting more thorough heat exchange, further improving the heat dissipation efficiency inside the heat-conducting component 43 and helping to reduce the internal temperature of the battery module 3 more quickly. The presence of the heat dissipation fins 44 changes the heat conduction path inside the heat-conducting component 43, allowing heat to be conducted more quickly from the inner wall of the heat-conducting component 43 to the fin surface and then to the air. This multi-path heat conduction method accelerates the heat dissipation rate, prevents heat accumulation inside the heat-conducting component 43, improves the overall heat dissipation performance of the heat-conducting component 43, and thus better protects the battery module 3.

[0062] Furthermore, each heat dissipation fin 44 is evenly arranged around the heat-conducting component 43, and the length direction of the heat dissipation fin 44 is consistent with the length direction of the heat-conducting component 43.

[0063] Because the heat dissipation fins 44 are evenly distributed around the heat conductor 43 and their length direction is consistent with the length direction of the heat conductor 43, heat can be evenly distributed and transferred inside the heat conductor 43. This helps to avoid local overheating of the battery module 3 caused by local heat concentration, ensures that each cell in the battery module 3 works in the same temperature environment, and improves the overall performance stability of the battery module 3.

[0064] The tubular structure, heat dissipation fins 44, and the design that is the same length as the battery module 3 work together to form a uniform and efficient heat dissipation network within the heat dissipation airflow of the battery module 3. Regardless of where the heat is generated in the battery module 3, it can be quickly and evenly dissipated through this heat dissipation network, ensuring the temperature consistency of the entire battery module 3 and improving the overall performance and reliability of the battery pack.

[0065] like Figure 4As shown, the inner wall of the battery module 3 is provided with a connecting groove 31, and the heat-conducting component 43 is provided with a protrusion 45 that matches the connecting groove.

[0066] The matching design of the protrusion 45 and the connecting groove 31 allows the heat-conducting component 43 to fit tightly against the inner wall of the battery module 3. This tight fit ensures maximum contact area between the heat-conducting component 43 and the battery module 3, reducing air gaps and thus improving heat conduction efficiency. Heat can be transferred more smoothly from the battery module 3 to the heat-conducting component 43, avoiding thermal resistance caused by poor contact and effectively improving heat dissipation.

[0067] During vehicle operation, vibrations and bumps may occur. The cooperation between the connecting groove 31 and the protrusion 45 prevents the heat-conducting component 43 from shifting within the heat dissipation duct. This ensures that the heat-conducting component 43 is always in the optimal heat dissipation position, stably exchanging heat with the battery module 3, thus guaranteeing the reliability and stability of the heat dissipation system.

[0068] When the heat-conducting component 43 is connected to the connecting groove 31 on the inner wall of the battery module 3 via the protrusion 45, it provides a certain degree of support for the outer casing of the battery module 3. Especially when the battery module 3 is subjected to external impact, the heat-conducting component 43 can disperse part of the impact force to the inner wall of the battery module 3 through the protrusion 45, reducing the stress on the outer casing, reducing the risk of deformation or damage to the outer casing, and protecting the safety of the internal cells of the battery module 3.

[0069] When installing the heat-conducting component 43, the matching of the protrusion 45 and the connecting groove 31 provides accurate installation position and direction guidance for the heat-conducting component 43. The operator only needs to align the protrusion 45 with the connecting groove 31 and insert it to complete the initial installation, which greatly improves the convenience and accuracy of installation and reduces the adjustment time and workload during the installation process.

[0070] In one alternative embodiment, the cross-section of the cavity 21 inside the mounting sleeve 2 and the battery module 3 are circular or polygonal.

[0071] The circular structure experiences uniform stress in all directions, with no obvious stress concentration points. When the battery pack is subjected to external pressure, impact, or vibration, the circular cavity 21 and battery module 3 can better distribute stress, reduce the risk of local damage, thereby improving the stability and reliability of the entire battery pack structure and helping to protect the internal components such as the battery cells of the battery module 3 from damage.

[0072] For air-cooled heat dissipation, the circular structure helps to create a more uniform airflow path. When air flows in a circular heat dissipation channel, the resistance is relatively small and the distribution is uniform, avoiding airflow turbulence or localized excessively fast or slow flow rates caused by structural abrupt changes. This allows for more consistent heat dissipation throughout the battery module 3, preventing localized overheating problems caused by uneven heat dissipation.

[0073] The polygonal structure, such as a square, allows the cavity 21 inside the mounting sleeve 2 and the battery module 3 to be arranged more tightly and regularly within the battery pack. Compared to other irregular shapes, the square shape can make better use of space and reduce gaps, thereby accommodating more battery modules 3 within a limited battery pack volume, increasing the energy density of the battery pack, and meeting the vehicle's demand for energy storage capacity.

[0074] The battery installation area inside a vehicle typically has certain shape and size limitations. The square battery module 3 and cavity 21 are easier to adapt to the vehicle's installation space. This allows for easier layout and installation, improving the convenience and compatibility of battery pack installation within the vehicle, reducing the space and structure required for additional design due to shape mismatch, and lowering the complexity of vehicle design and manufacturing.

[0075] A second aspect of this application provides a vehicle that includes the battery pack structure provided in the first aspect.

[0076] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
