Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery thermal management structure technology, specifically a cell module structure with heat energy dissipation function. Background Technology
[0002] As an indispensable component in battery module manufacturing, the structural stability and thermal control capabilities of the cell mold directly affect the uniformity and quality consistency of the module pressing process. During the operation of the cell mold, due to continuous heating, pressing, or other process effects, a large amount of heat is generated inside the module. If this heat is not dissipated in time, it will not only lead to uneven temperature distribution within the mold cavity, affecting the module's cooling effect and molding quality, but may also cause problems such as component structural deformation and cell performance degradation due to heat retention, thereby reducing the overall production efficiency and reliability of the module.
[0003] For example, utility model CN209312828U discloses a battery cell module assembly. This assembly forms an internal liquid cooling channel by setting a flow-guiding flat tube between adjacent battery cells, with water inlets on both sides, and connecting to an external water system via connecting pipes. This achieves rapid cooling and heating regulation of the module, improving the temperature uniformity and regulation efficiency within the module. This solution effectively improves the distribution of heat energy within the module through liquid cooling, helping to extend the battery cell's lifespan and enhance safety.
[0004] However, this structure primarily relies on the diffusion of internal heat and the circulation of coolant to regulate temperature. It lacks an effective mechanism for guiding and actively removing internal heat, making it easy for heat to accumulate within the module structure and hindering the rapid removal of hot air. This accumulation is particularly pronounced during extended module operation or under heavy heat loads, potentially leading to a sustained increase in the overall module temperature and causing risks such as thermal deformation, performance degradation, or even damage to the battery cell module structure.
[0005] Therefore, in order to address the technical shortcomings of existing technologies where heat energy can diffuse within the module but is difficult to effectively remove, it is urgent to propose a cell module structure with a clear heat energy removal path. Through structural optimization and airflow control, the heat inside the module can be discharged in a timely manner, thereby improving the thermal stability and operational reliability of the module structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A battery cell mold structure with heat dissipation function includes a protective cover, and a battery cell mold is disposed inside the protective cover. A sealing cover is disposed on the top of the protective cover. A mounting frame is disposed inside the protective cover, and a ventilation plate is installed inside the mounting frame. A cooling component is disposed inside the mounting frame.
[0009] The cooling assembly includes a guide tube, which is disposed inside the mounting frame. Several air outlet pipes are connected to the surface of the guide tube. A miniature blower is installed on the outside of the protective cover. One end of the guide tube is connected to the surface of the miniature blower, and the other end is disposed outside the protective cover.
[0010] Furthermore, the surface of the ventilation plate is provided with a number of ventilation holes.
[0011] Furthermore, a filter plate is provided at the end of the mounting frame away from the sealing cover, and the filter plate is snapped together with the protective cover.
[0012] Furthermore, positioning components are provided on both sides of the filter plate, and snap-fit grooves are provided on both sides inside the protective cover.
[0013] The positioning component includes a telescopic rod, which is installed on the side of the filter plate.

[0020] The battery cell mold structure with heat dissipation function provided by this utility model has the following beneficial effects:
[0021] This invention creates a through-flow heat dissipation path by setting a guide tube inside the mounting frame, connecting one end of the tube to a miniature blower outside the protective cover, and extending the other end to the outside of the protective cover. This allows the hot air accumulated inside the cell mold to be guided to the outside in a timely manner during the operation of the cell mold, effectively reducing heat accumulation inside the structure and improving the heat dissipation efficiency and operational stability of the cell mold.
[0022] By setting multiple air outlets on the surface of the guide tube, the area for capturing hot air can be expanded, allowing heat to be more evenly collected and discharged in the guide path, further enhancing the overall performance of the cooling system. The guide tube is secured in the receiving groove of the sealing cap, and the installation method, which runs through both sides of the mounting frame, ensures a stable and fixed heat conduction path, reduces the risk of structural shaking or loose connections during operation, and enhances the overall sealing and reliability of the system.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0030] like Figures 1-4As shown in the figure, the present invention provides a battery cell mold structure with heat dissipation function, including a protective cover 1, and a battery cell mold 2 is disposed inside the protective cover 1. A sealing cover 3 is disposed on the top of the protective cover 1. A mounting frame 4 is disposed inside the protective cover 1, and a ventilation plate is installed inside the mounting frame 4. The surface of the ventilation plate has a plurality of ventilation holes. A cooling component 5 is disposed inside the mounting frame 4.
[0031] The cooling assembly 5 includes a guide tube 52, which is disposed inside the mounting frame 4. Several air outlet pipes 54 are connected to the surface of the guide tube 52. A miniature blower 51 is mounted on the outside of the protective cover 1. One end of the guide tube 52 is connected to the surface of the miniature blower 51, and the other end is disposed outside the protective cover 1. Two through holes are opened on the side of the mounting frame 4, and the guide tube 52 is disposed inside the two through holes. Two receiving grooves are opened on one side of the surface of the sealing cover 3, and the guide tube 52 is inserted into the two receiving grooves.
[0032] In one embodiment of this invention, when the battery cell module 2 is in operation, it continuously generates heat. This heat flows upward along the inside of the mounting frame 4 and is locally dissipated through several ventilation holes on the ventilation plate. To further improve the efficiency of heat dissipation, the user can activate the miniature blower 51 located outside the protective cover 1. After being powered on, the miniature blower 51 generates airflow, which is transported to the outside of the protective cover 1 through the guide pipe 52 connected to it. Since one end of the guide pipe 52 is connected to the miniature blower 51 and the other end is located outside the protective cover 1, a closed flow path is formed, thereby achieving continuous outward transport of internal hot air.
[0033] During the extraction of hot air, the guide tube 52 serves as the main channel. The air inside the guide tube flows in a fixed direction under the action of the blower 51, while simultaneously absorbing the heat energy emitted by the ventilation plate through several surface-connected exhaust pipes 54. These exhaust pipes 54 cover the internal area of the mounting frame 4, thereby enhancing the heat capture range. The guide tube 52 passes through two through holes installed on the side of the mounting frame 4 and is secured in two receiving grooves on the sealing cover 3, ensuring that the guide tube 52 is stably fixed during operation, preventing shaking or detachment, and guaranteeing a continuous and reliable heat conduction path.
[0034] This structure utilizes the combined action of a blower and a guide tube to actively expel the heat generated by the battery cell module 2 during operation, significantly reducing the risk of internal heat buildup and effectively preventing performance degradation or structural damage caused by overheating. Simultaneously, the guide path is positioned within a storage groove, preventing structural exposure from affecting overall sealing and further enhancing the overall practicality and safety of the structure.
[0035] In this embodiment, the guide tube 52 is arranged in a continuous, winding pattern along the plane inside the mounting frame 4, which significantly increases its overall path length within a limited space, thereby increasing its contact area with the internal hot air. This arrangement not only extends the flow path of the hot air within the guide tube but also effectively improves the heat conduction efficiency, allowing the heat to be fully carried away by the blowing airflow over a longer period of time.
[0036] The coiled arrangement also has the advantages of compact structure and orderly layout, which can make full use of the internal space of the mounting frame 4 and achieve efficient heat dissipation without affecting the installation of other components. At the same time, this arrangement helps to reduce the disturbance and turbulence of hot air during the flow process, maintain the stability of the heat conduction path and the consistency of the heat dissipation effect, and improve the reliability and operating efficiency of the overall cooling system.
[0037] In this embodiment, a filter plate 6 is provided at the end of the mounting frame 4 away from the sealing cover 3, and the filter plate 6 is snap-fitted to the protective cover 1. This design allows external air to be guided into the interior of the protective cover 1 as the guide tube 52 drives the airflow. Because the filter plate 6 and the protective cover 1 are snap-fitted together, installation and disassembly are simple, allowing for quick replacement or cleaning.
[0038] This structure offers two significant advantages. First, the filter plate 6 provides initial filtration of dust, impurities, and other foreign objects in the incoming air, preventing them from entering the working area of the battery cell mold 2 with the airflow. This avoids contamination or damage to the battery cell mold, improving overall safety and stability. Second, the snap-fit connection not only enhances the ease of assembly but also facilitates later maintenance. The filter plate can be disassembled and assembled without tools, significantly improving the maintainability and practicality of the equipment.
[0039] In this embodiment, positioning components 7 are provided on both sides of the filter plate 6, and snap-fit grooves are provided on both sides inside the protective cover 1. The positioning component 7 includes a telescopic rod 71, which is installed on the side of the filter plate 6. A positioning block 73 is provided at the end of the telescopic rod 71 away from the filter plate 6. A spring 72 is installed on the side of the positioning block 73 and the side of the filter plate 6 that are close to each other. The side surface of the positioning block 73 is provided with a beveled structure, and the shape of the positioning block 73 is adapted to the shape of the snap-fit groove.
[0040] When the filter plate 6 needs to be installed inside the protective cover 1, the operator can directly push the filter plate 6 into the protective cover 1 along the axial direction. Since the side surface of the positioning block 73 is provided with a sloped structure, during the pushing process, the snap-fit grooves on both sides inside the protective cover 1 will squeeze the slope of the positioning block 73, so that the positioning block 73 overcomes the elastic force of the spring 72 under pressure and retracts inward along the direction of the telescopic rod 71, thus smoothly passing through the narrow entrance of the snap-fit groove.
[0041] Once the filter plate 6 is moved to the target installation position, the compressive force is released, and the spring 72 automatically releases, causing the positioning block 73 to spring back to both sides, embedding it into the snap-fit groove, thereby achieving a secure positioning of the filter plate 6. The entire installation process requires no additional tools, relying on the inherent elasticity of the structure to complete the self-locking operation, resulting in strong stability and convenient assembly and disassembly.
[0042] This structure enables rapid installation and positioning of the filter plate, improving operational efficiency and making it suitable for scenarios requiring frequent replacement or maintenance. Furthermore, the spring 72 provides a continuous and stable preload force, which, combined with the shape matching of the positioning block 73 and the snap-fit groove, prevents the installed filter plate from loosening or shifting during operation. This helps ensure the airflow path's sealing and the reliability of the filtration effect, enhancing the stability and safety of the entire cooling airflow system.
[0043] In this embodiment, several reinforcing tubes 53 are sleeved on the outer side of the guide tube 52, and the air outlet pipe 54 passes through the reinforcing tubes 53. During the installation of the guide tube 52, several reinforcing tubes 53 are sleeved on its outer side, and the air outlet pipe 54 passes through the middle of the reinforcing tubes 53. Through this structural arrangement, the guide tube 52 not only has the function of airflow conduction, but also significantly improves its overall rigidity and resistance to deformation. The setting of the reinforcing tubes 53 can effectively prevent the guide tube from bending, collapsing, or shifting its position when subjected to external assembly stress, airflow pulsation, or vibration disturbance, thus maintaining its shape stability.
[0044] After the air outlet pipe 54 passes through the reinforcing pipe 53, its airflow channel is connected to the inside of the guide pipe 52. During the airflow process, it can guide the hot air in the mounting frame 4 to be drawn into the guide pipe from multiple distribution points. This multi-point heat absorption structure can expand the heat capture range, make the heat conduction process more uniform and efficient, and avoid local heat retention.
[0045] This structure achieves both mechanical enhancement and functional expansion of the guide tube in the cooling path, improving both overall structural strength and heat dissipation efficiency. Simultaneously, the through-type exhaust pipe arrangement facilitates later cleaning and maintenance, demonstrating good practicality and engineering adaptability.
[0046] In this embodiment, a sealing ring is provided at the edge of the surface of the protective cover 1, and the outer dimensions of the sealing ring are adapted to the mating boundary dimensions inside the sealing cover 3. This design enables the sealing cover 3 to form a reliable sealing interface when combined with the protective cover 1.
[0047] This structure helps prevent unfiltered impurities, dust, or moisture from the outside air from directly entering the protective cover, especially when the blower system is operating and creating an airflow channel, effectively maintaining a clean and dry working environment for the battery cell mold. Simultaneously, the sealing ring also prevents internal hot air or particulate matter from leaking to the outside of the sealing joint due to airflow disturbances, thereby maintaining the stability of the internal air pressure and air path, and preventing disruption to the heat dissipation path.
[0048] This sealing not only improves the overall airtightness and environmental adaptability of the structure, but also helps protect internal components from corrosion, contamination and overheating risks, thereby improving the overall operational reliability and lifespan of the battery cell module.
[0049] In this embodiment, a support base is provided on the side of the protective cover 1, and the miniature blower 51 is mounted on the surface of the support base. In this structure, the support base is provided on the side of the protective cover 1 for mounting the miniature blower 51. By directly fixing the blower to the surface of the support base, it can be ensured that it maintains a stable posture during operation, avoiding problems such as displacement, loosening, or poor contact caused by vibration or airflow pulsation.
[0050] This support base provides a solid mounting foundation for the blower, helping to effectively transmit the mechanical vibrations generated during operation to the protective cover body and avoiding localized stress concentration at the guide tube connection or surrounding components. At the same time, the lateral mounting position facilitates a straight path between the blower and the guide tube, shortening the airflow transmission path, reducing energy loss, and improving cooling efficiency.
[0051] This structure not only optimizes the way the blower is fixed, improving assembly reliability and the continuity of airflow transmission, but also facilitates the inspection or replacement of the blower during subsequent maintenance, thus improving the ease of use and maintainability of the system.
[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
