Description

Technical Field

[0001] This utility model relates to the field of new energy and discloses a novel thermal management device for soft-pack CTP batteries. Background Technology

[0002] As a crucial component of the new energy field, pouch CTP batteries generate a significant amount of heat during operation. If this heat cannot be dissipated in a timely manner, it can lead to excessively high battery temperatures, affecting battery performance, lifespan, and safety. In extreme cases, it may even trigger dangerous situations such as thermal runaway. Therefore, efficient thermal management equipment is essential for the stable operation of pouch CTP batteries.

[0003] The heat dissipation structure design of the traditional soft-pack CTP battery thermal management equipment currently in use has limitations. For example, relying on a single heat dissipation method is insufficient in heat dissipation capacity under extreme operating conditions, making it difficult to quickly dissipate the heat generated by the battery cell. At the same time, some equipment adds extra heat dissipation components to enhance the heat dissipation effect, which takes up more space, which is not conducive to the compact layout of the battery pack and affects the overall integration efficiency.

[0004] Current traditional thermal management devices for pouch CTP batteries have limitations in their limiting structures. For example, they may have poor limiting performance, making it difficult to adapt to the fixing requirements of different sized cell modules; or they may have complex structures, making installation and disassembly inconvenient, and their buffering performance is poor when subjected to external vibrations, failing to effectively protect the cell modules. Therefore, a novel thermal management device for pouch CTP batteries is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel thermal management device for soft-pack CTP batteries, which aims to improve the problems of single heat dissipation effect and inability to protect the cell module in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel thermal management device for soft-pack CTP batteries includes a housing, a blower box fixedly connected to one side of the housing, a motor fixedly connected to one side of the blower box, a fan rod fixedly connected to the drive end of the motor, a plurality of fan blades fixedly connected to the outer wall of the fan rod, a ventilation plate fixedly connected to one side of the housing, a ventilation opening provided at the top of the ventilation plate, a support plate fixedly connected to the outer periphery of the ventilation plate, a ventilation opening provided at the top of the support plate, and a plurality of limiting components provided on both sides of the housing.

[0008] As a further description of the above technical solution:

[0009] The limiting assembly includes the outer plate, the limiting spring is fixedly connected to the inner side of the outer plate, the other end of the limiting spring is fixedly connected to the inner plate, the limiting plate is fixedly connected to the inner side of the inner plate, and the box girder is fixedly connected to the outer side of the outer plate.

[0010] As a further description of the above technical solution:

[0011] The top of the tray is provided with the thermally conductive adhesive, and the top of the thermally conductive adhesive is fixedly connected to the battery cell module.

[0012] As a further description of the above technical solution:

[0013] Multiple battery cells are fixedly connected to the top of the battery cell module.

[0014] As a further description of the above technical solution:

[0015] The bottom of the tray is provided with the thermally conductive adhesive.

[0016] As a further description of the above technical solution:

[0017] The liquid cooling plate is fixedly connected to the bottom of the thermally conductive adhesive.

[0018] As a further description of the above technical solution:

[0019] The top of the box is fixedly connected to the box cover.

[0020] As a further description of the above technical solution:

[0021] The top of the box lid is fixedly connected to the pull ring.

[0022] This utility model has the following beneficial effects:

[0023] In this invention, a highly efficient air-cooled heat dissipation system is formed by setting up a wind box, motor, fan rod, fan blades, ventilation plate, and support plate on one side of the housing. The motor drives the fan rod to rotate, which in turn drives the fan blades to generate airflow. The airflow is transmitted through the ventilation ports on the ventilation plate and support plate and blown onto the battery cells. The airflow within the support plate enhances heat dissipation, significantly improving thermal management efficiency and quickly dissipating the heat generated by the battery cells during operation.

[0024] In this invention, the effective limiting and buffering of the battery cell module is achieved through the cooperation of the outer plate, limiting spring, inner plate, limiting plate, and box girder. The limiting spring has elastic deformation capability. When the battery cell module is subjected to external vibration or impact, the limiting spring can absorb the impact force through extension and contraction, reducing the shaking and displacement of the battery cell module, preventing the battery cell from colliding and being damaged with other components, and ensuring the structural stability and safety of the battery cell module.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2This utility model provides an embodiment of a novel thermal management device for soft-pack CTP batteries, comprising a housing 1, which serves as the main frame of the entire device, accommodating and supporting other structures such as a blower box 2, a ventilation plate 6, and a support plate 7. A blower box 2 is fixedly connected to one side of the housing 1, providing installation space for a motor 3, a fan rod 4, and fan blades 5, thus protecting internal components and guiding airflow. A motor 3 is fixedly connected to one side of the blower box 2, with its drive end connected to the fan rod 4, providing power for the rotation of the fan rod 4 and fan blades 5. The drive end of the motor 3 is fixedly connected to the fan rod 4, with one end fixed to the drive end of the motor 3. The outer wall is connected to the fan blades 5, which rotate under the drive of the motor 3. The fan blade 5 generates wind power. Multiple fan blades 5 are fixedly connected to the outer wall of the fan rod 4. They are fixed to the outer wall of the fan rod 4 and generate wind power as the fan rod 4 rotates, providing airflow for the air-cooling heat dissipation of the equipment. A ventilation plate 6 is fixedly connected to one side of the housing 1. It has a vent on the top to transfer the wind power generated by the fan blades 5 to the support plate 7. The top of the ventilation plate 6 has a vent. The support plate 7 is fixedly connected to the outer periphery of the ventilation plate 6. It has a vent on the top to support the battery cell module 14 and blow the wind power from the ventilation plate 6 to the battery cell 15 through the vent. At the same time, the internal airflow enhances heat dissipation. The top of the support plate 7 has a vent. Multiple limiting components are provided on both sides of the housing 1.

[0034] Reference Figure 1 and Figure 3 The limiting component includes an outer plate 8, which serves as the external structure of the limiting component. A limiting spring 9 is connected to the inner side of the outer plate 8, and a box beam 12 is connected to the outer side of the outer plate 8, providing support for the limiting component. The limiting spring 9 is fixedly connected to the inner side of the outer plate 8, connecting the outer plate 8 and the inner plate 10. It absorbs the impact force through elastic deformation, playing a buffering and limiting role for the battery cell module 14. The other end of the limiting spring 9 is fixedly connected to the inner plate 10, with a limiting plate 11 connected to the inner side and the limiting spring 9 connected to the outer side, transmitting the elastic force of the limiting spring 9. It works with the limiting plate 11 to limit the battery cell module 14. The limiting plate 11 is fixedly connected to the inner side of the inner plate 10, and is fixed inside the inner plate 10, directly contacting the battery cell module 14 to limit the battery cell module 14 and prevent its displacement. The box beam 12 is fixedly connected to the outer side of the outer plate 8, and is fixed outside the outer plate 8, enhancing the structural strength of the outer plate 8 and improving the stability of the limiting component.

[0035] Reference Figure 1 , Figure 4 and Figure 5The top of the tray 7 is provided with thermally conductive adhesive 13, which connects the tray 7 and the cell module 14, enhancing heat conduction between them and assisting in heat dissipation. The top of the thermally conductive adhesive 13 is fixedly connected to the cell module 14, and the bottom is connected to the tray 7 through the thermally conductive adhesive 13. The top of the cell module 14 is connected to the cell 15, serving as the integrated carrier for the cell 15. Multiple cell 15s are fixedly connected to the top of the cell module 14, which is the core component of the battery. Heat dissipation is achieved through air cooling of the tray 7 and liquid cooling of the liquid cooling plate 17. The bottom of the tray 7 is provided with thermally conductive adhesive. Adhesive 16 is installed at the bottom of the tray 7, connecting the tray 7 and the liquid cooling plate 17, enhancing the heat conduction between the two and assisting in liquid cooling heat dissipation. The bottom of the thermally conductive adhesive 16 is fixedly connected to the liquid cooling plate 17, and is connected to the tray 7 through the thermally conductive adhesive 16. It works in conjunction with air cooling to enhance heat dissipation redundancy under extreme conditions. The top of the box 1 is fixedly connected to the box cover 18, which is used to cover the box 1 and protect the internal battery cell module 14. The top of the box cover 18 is fixedly connected to the pull ring 19, which is fixed to the top of the box cover 18 to facilitate the handling or opening of the box cover 18.

[0036] Working Principle: The housing 1 serves as the main frame, integrating efficient heat dissipation and stable positioning functions. Its structure is meticulously designed and highly coordinated. Regarding the heat dissipation system, a fan box 2 fixed to one side of the housing 1 provides the power for heat dissipation. A motor 3 on the fan box 2 drives the fan rod 4 to rotate, causing multiple fan blades 5 on the outer wall of the fan rod 4 to generate continuous airflow. This airflow is conducted through the ventilation port on the top of the ventilation plate 6 on one side of the housing 1 to the support plate 7 fixed to the outer periphery of the ventilation plate 6. The airflow then directly acts on the battery cell 15 through the ventilation port on the top of the support plate 7. The airflow circulation within the support plate 7 enhances local heat dissipation efficiency. Simultaneously, the bottom of the support plate 7 is tightly connected to the liquid cooling plate 17 via thermally conductive adhesive 16. The heat generated by the battery cell 15 is transferred to the support plate 7 via the battery cell module 14 and the thermally conductive adhesive 13 on the top of the support plate 7, and then efficiently conducted to the liquid cooling plate 17 by the thermally conductive adhesive 16. This achieves coordinated heat dissipation through air cooling and liquid cooling, significantly improving heat dissipation redundancy under extreme conditions without requiring additional space. In terms of limit protection, the multiple limit components on both sides of the housing 1 have an ingenious structure. The limit spring 9 on the inner side of the outer plate 8 connects to the inner plate 10, and the limit plate 11 on the inner side of the inner plate 10 directly fits the cell module 14. The elastic deformation of the limit spring 9 can effectively buffer external vibrations and reduce the shaking displacement of the cell module 14. The box beam 12 on the outer side of the outer plate 8 enhances the overall structural strength of the limit components and ensures stable limit effect. In addition, the box cover 18 on the top of the housing 1 can provide comprehensive protection for the internal components. The pull ring 19 on the top of the box cover 18 is easy to operate. Through the precise cooperation of each component, the whole device achieves efficient thermal management and stable protection of soft-pack CTP batteries during operation.
