[0002] With the rapid development of new energy technologies, lithium battery modules, as the core energy source for many electric drive devices, are becoming increasingly critical in terms of performance and stability. In practical applications, lithium battery modules inevitably generate a large amount of heat during charging and discharging.

[0025] Example

[0026] Reference Figure 1-4 This embodiment of the present invention provides a wind-cooled heat dissipation device for a lithium battery module used in industrial mobile robots, comprising:

[0027] The support assembly 100 includes a connector 101, a cover plate 102 fixedly installed on the side wall of the connector 101, and an adapter pipe 103 threadedly connected to the side wall of the connector 101, the adapter pipe 103 communicating with the interior of the connector 101.

[0028] The heat dissipation assembly 200 includes a frame 201 snapped onto the upper end of the cover plate 102, a heat sink 202 fixedly connected inside the frame 201, a protective plate 203 fixedly connected to the upper end of the frame 201, and a fan 204 fixedly connected to the middle of the protective plate 203. The heat sink 202 is inserted into the groove in the middle of the cover plate 102.

[0029] The connector 101 connects the various parts and has an internal cavity to facilitate the introduction of liquid for auxiliary cooling. The cover plate 102 is snapped onto the outside of the battery pack, increasing the stability of the connection with the connector 101 and also protecting the battery pack. The adapter pipe 103 is threaded to the side wall of the connector 101, enabling communication with the inside of the connector 101. This further facilitates the introduction of liquid or cooling gas for auxiliary cooling of the battery pack. The heat sink 202 is fixedly connected to the inside of the frame 201 to increase the heat dissipation area of ​​the battery pack and effectively improve heat dissipation efficiency. The protective plate 203 is used to install the fan 204 and also shields the side wall of the fan 204 to prevent foreign objects from entering and affecting the normal operation of the fan. When the fan 204 is running, it generates airflow, accelerates air movement, and carries away heat, thus achieving the heat dissipation function.

[0030] Specifically, the heat dissipation assembly 200 also includes an air inlet pipe 205 threadedly connected to one side of the frame 201, the end of the air inlet pipe 205 extending to the side wall of the heat sink 202, and an air outlet for use with the air inlet pipe 205 and the heat sink 202 is provided on the other side of the frame 201.

[0031] The air inlet duct 205 is used to draw external cold air to the heat sink 202, providing an additional cold source for heat dissipation and ensuring the cooling effect.

[0032] Furthermore, the heat dissipation assembly 200 also includes a baffle 206 inserted into the side wall of the air outlet of the frame 201, and the baffle 206 is inserted into the outside of the heat sink 202.

[0033] The baffle 206 is inserted into the side wall of the air outlet of the frame 201, and the size of the air outlet can be adjusted to control the air flow.

[0034] Furthermore, the heat dissipation assembly 200 also includes a knob 207 rotatably connected to the side wall of the frame 201, with the end of the knob 207 threadedly connected to the side wall of the baffle 206.

[0035] The knob 207 is rotatably connected to the side wall of the frame 201. By rotating the knob 207, the position of the baffle 206 can be easily controlled, thereby adjusting the size of the air outlet to adapt to different heat dissipation needs.

[0036] Preferably, the side wall of the cover plate 102 is provided with a bent edge structure, and the bent edge of the side wall of the cover plate 102 extends to the bottom of the connector 101.

[0037] The side bend of the cover plate 102 is used to shield and protect the battery pack, while maintaining the connection accuracy between the cover plate 102 and the battery pack and preventing the heat dissipation device from becoming loose.

[0038] It should be noted that the support assembly 100 also includes a pipe joint 104 threaded to the end of the adapter pipe 103, and an extension pipe 105 sealed to the end of the pipe joint 104. The extension pipe 105 communicates with the interior of the adapter pipe 103 through the pipe joint 104. The connector 101 has a cavity structure inside that cooperates with the adapter pipe 103. One set of connectors 101 communicates with another set of connectors 101 through the extension pipe 105.

[0039] The extension tube 105 is internally connected to the adapter tube 103 via the tube connector 104. One set of connectors 101 can be connected to another set of connectors 101 through the extension tube 105. This design gives the entire support assembly good scalability and flexibility in gas delivery, allowing it to be used for combined heat dissipation of battery packs of different sizes, and it is easy to assemble and disassemble.

[0040] During use, when the lithium battery module's air-cooling device is operating, the fan 204 starts, generating airflow. External cold air enters the frame 201 through the air inlet duct 205 and flows over the heat sink 202. Because the heat sink 202 increases the contact area with the air, the cold air can fully absorb the heat dissipated by the lithium battery module, thus achieving heat dissipation. Hot air is exhausted from the air outlet on the other side of the frame 201. During this process, if it is necessary to adjust the airflow at the air outlet, the knob 207 can be rotated. The knob 207 moves the threaded baffle 206, changing the size of the air outlet to meet different heat dissipation requirements. Simultaneously, the connectors 101, adapter pipes 103, pipe joints 104, and extension pipes 105 in the support assembly 100 cooperate to achieve communication between multiple devices, allowing for reasonable airflow throughout the system. The heat dissipation system can be flexibly configured according to the actual layout and heat dissipation requirements of the lithium battery module.

[0041] In summary, the design of the heat sink 202 increases the heat dissipation area. Combined with the airflow generated by the fan 204, it can quickly remove the heat generated by the battery pack, ensuring the battery pack operates within a suitable temperature range, extending battery life, and improving battery performance. The knob 207 and baffle 206 allow for convenient adjustment of the air outlet size according to different heat dissipation conditions of the battery pack, precisely controlling airflow and achieving flexible and efficient heat dissipation adjustment. The bent edge structure of the cover 102 and the protective plate 203 respectively protect the components below and the fan 204, reducing the risk of damage to critical internal components from external objects and improving the stability and reliability of the device. The connection methods of the connector 101, adapter pipe 103, pipe joint 104, and extension pipe 105 in the support assembly 100 allow for easy connection between multiple devices. A heat dissipation system can be flexibly constructed according to the actual layout and heat dissipation requirements of the battery pack, meeting the needs of heat dissipation scenarios of different scales and complexities.
