Description

Technical Field

[0001] This utility model relates to the field of battery cooling device technology, and in particular to a terminal cooling structure. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the performance and safety of power batteries, as core components, have attracted much attention. During the charging and discharging process of power batteries, the cell terminals generate a large amount of heat. If this heat cannot be dissipated effectively and in a timely manner, the cell temperature will become too high, affecting the battery's charging and discharging efficiency, cycle life, and even causing serious safety hazards such as thermal runaway. Therefore, developing efficient and reliable cell terminal cooling technology has become a key issue in the field of power batteries. Traditional power battery heat dissipation methods have many shortcomings. Early air-cooling methods, although simple in structure and low in cost, have limited heat dissipation efficiency. Due to the low specific heat capacity of air, it is difficult to quickly remove the large amount of heat generated by the cell terminals, especially when the battery is operating under high load, which cannot meet the heat dissipation requirements, resulting in a significant decline in battery performance. Existing power battery heat dissipation technologies have problems such as low heat dissipation efficiency, unstable fixing, untimely monitoring, and poor dust prevention performance in terms of cell terminal cooling. Therefore, a new type of liquid cooling structure for power battery cell terminals is needed. Utility Model Content

[0031] The following is combined with Figures 1-4 This invention describes the electrode cooling structure provided by the present invention.

[0032] In view of the problems of low cooling efficiency and poor safety of battery cooling devices in traditional technology, this utility model provides a pole cooling structure, including a housing 1, a cooling component 2, multiple pole fixing components 3 and a temperature sensor 4.

[0033] Please see Figure 1 The housing 1 includes a detachably connected housing body 11 and a cover plate 12. The housing body 11 has an installation cavity 13, and the cooling component 2 is disposed in the housing body 11. The detachable housing 1 facilitates disassembly and maintenance, reducing maintenance costs. Multiple electrode fixing components 3 are spaced apart on the bottom wall of the installation cavity 13. By setting multiple electrode fixing components 3, the cooling efficiency of the electrode can be effectively improved. In addition, the spaced electrode fixing components 3 can also ensure uniform heat dissipation of the electrode and avoid local overheating.

[0034] Specifically, each electrode fixing component 3 includes a cooling platform 31, with a positioning groove 32 for placing the electrode to be cooled. The cooling platform 31 is made of a highly thermally conductive material, such as copper, aluminum alloy, or ceramic. The cooling platform 31 can promptly transfer the cooling energy of the cooling component 2 to the electrode, allowing the electrode to cool down rapidly, while the mounting groove provides stable fixation for the electrode. Furthermore, a temperature sensor 4 is located on the side of the cover plate 12 facing the mounting cavity 13 to sense the temperature inside the mounting cavity 13. The temperature sensor 4 can monitor the electrode cooling in real time, significantly improving safety.

[0035] As previously mentioned, the cooling element 2 is disposed on the housing body 11. In an optional embodiment, the cooling element 2 can be disposed on each inner wall of the mounting cavity 13 to provide sufficient cooling for the electrode post. In other optional embodiments, the cooling element 2 can also be disposed on one inner wall of the mounting cavity 13, either within the inner wall or outside the inner wall. To reduce costs and to prevent interference between the installation of the cooling element 2 and the electrode post fixing member 3, please refer to [link to relevant documentation]. Figure 2 In the technical solution provided by this utility model, the housing 1 also has a receiving cavity 14, which is separated from the mounting cavity 13 by the bottom wall of the mounting cavity 13. The cooling component 2 is disposed in the receiving cavity 14 and close to the bottom wall of the mounting cavity 13. Specifically, the bottom wall of the mounting cavity 13 can also be made of a high thermal conductivity material. The double-layer cavity can achieve physical isolation between the cooling medium and the electrode, eliminating the safety hazards caused by liquid leakage. In addition, the independent layout of the receiving cavity 14 also facilitates centralized maintenance of the cooling system.

[0036] Please see Figure 3The cooling component 2 includes a cooling tank 21, an outlet connector 22, an inlet connector 23, a pump body 24, and cooling pipes 25. The outlet connector 22 and the inlet connector 23 are respectively located at the outlet end and the inlet end of the cooling tank 21. The two ends of the cooling pipes 25 are connected to the outlet connector 22 and the inlet connector 23, respectively. It should be noted that the closed-loop circulation can reduce the consumption of cooling medium and lower operating costs; the pump body 24 drives the medium to flow continuously, realizing dynamic heat exchange and avoiding the efficiency decay of static cooling; in addition, the modular design of the pipeline and tank also facilitates system expansion or replacement.

[0037] In the technical solution provided by this utility model, the cooling pipes 25 are sequentially bent along the length of the shell body 11 to form multiple cooling sections spaced apart along the length of the shell body 11. The cooling pipes 25 can be flexible or plastically designed, and the cooling sections can be smoothly connected or bent at angles; this utility model does not limit this. This design increases the contact area with the bottom wall of the mounting cavity 13 by bending the pipes, enhancing overall heat dissipation; the parallel cooling sections uniformly absorb heat, eliminating cooling blind spots; and the continuous flow channel design reduces fluid resistance and improves circulation efficiency.

[0038] Furthermore, each cooling platform 31 is configured in a one-to-one correspondence with each cooling section, and both the cooling platform 31 and each cooling section extend along the width direction of the shell body 11. With this configuration, the cooling platforms 31 and cooling sections are aligned vertically to shorten the heat transfer distance and accelerate the cooling speed of the electrode; the laterally extending cooling platforms 31 can also increase the contact area with the electrode and improve the uniformity of heat conduction.

[0039] It should be noted that the mounting groove can be determined according to the size and shape of the electrode post. When the electrode post is cylindrical, the mounting groove can be set to an arc shape. To improve the stability of the electrode post fixing, in the technical solution provided by this utility model, the electrode post fixing component 3 includes a fastening part, which includes a fixed clamp 33 and a movable clamp 34. The fixed clamp 33 is located on one side of the positioning groove 32, and the movable clamp 34 is rotatably located on the other side of the positioning groove 32. The movable clamp 34 and the fixed clamp 33 are detachably connected and used to engage and fix the electrode post to be cooled together with the positioning groove 32. The movable clamp 34 and the fixed clamp 33 can be set to extend along the cooling platform 31 for a certain length, which facilitates the stable fixing of the electrode post; alternatively, the movable clamp 34 and the fixed clamp 33 can be set as short rings, and the various positions of the electrode post can be fixed sequentially by multiple movable clamps 34 and fixed clamps 33. This utility model does not limit this.

[0040] Specifically, the movable clamp 34 has a protruding rib 35 at its end, and the fixed clamp 33 has an insertion hole 36 at its end. The protruding rib 35 and the insertion hole 36 are adapted to detachably connect the fixed clamp 33 and the movable clamp 34. The insertion structure of the protruding rib 35 and the insertion hole 36 provides mechanical interlocking to prevent accidental loosening; the insertion direction is consistent with the opening and closing action, conforming to ergonomic operating habits; the matching design ensures locking accuracy and reduces assembly errors. In other optional embodiments, snap-fit ​​installation, magnetic installation, etc., can also be selected. To improve the adaptability to fixing various types of poles, the movable clamp 34 can be elastically set.

[0041] Further, please refer to Figure 4 A display screen 5 is located on the side of the cover plate 12 away from the mounting cavity 13. The display screen 5 is electrically connected to the temperature sensor 4 and displays the temperature detected by the temperature sensor 4. Visualizing the temperature data helps users monitor the heat dissipation status in real time and provides early warning of abnormal temperature rises. The external location of the display screen 5 also avoids the need to open the cover, reducing interference from the external environment. Furthermore, a monitoring alarm 6 is also located on the cover plate 12. The monitoring alarm 6 is electrically connected to the temperature sensor 4, and the cover plate 12 also has a sound amplification hole 15 with a dustproof mesh. The monitoring alarm 6 can be a ring alarm or a sound and light alarm. The monitoring alarm 6 enables active safety protection, preventing overheating-induced malfunctions. The sound amplification hole 15 can directionally propagate the alarm sound, improving the warning effect. The dustproof mesh prevents foreign objects from entering the cavity, ensuring the long-term reliability of the sensor.

[0042] As mentioned above, the shell body 11 and the cover plate 12 are detachably connected. Specifically, the cover plate 12 has multiple bolts 16 on its periphery, and the shell body 11 has multiple corresponding screw holes 17. Each bolt 16 is threaded into the corresponding screw hole 17, so that the shell body 11 and the cover plate 12 are detachably connected. In actual operation, the user can rotate the bolts 16 to connect or disconnect the shell body 11 and the cover plate 12. In other optional embodiments, the connecting bolt and connecting hole can be inserted, or a magnetic attraction method can be selected; this utility model is not limited in this regard.

[0043] Finally, temperature sensor 4 can be set to one or more. When multiple temperature sensors 4 are set, temperature can be detected at various positions of the mounting cavity 13, with higher detection accuracy and more comprehensive control over the heat dissipation of the pole.

[0044] The working principle of the pole cooling structure provided by this utility model is as follows:

[0045] Place the battery cell terminals requiring cooling on the cooling platform 31. Insert one end of the cell terminal into the fixing clamp 33, adjust the position of the movable clamp 34 so that the movable clamp 34 fits over the other end of the cell terminal, aligning and connecting the protruding rib 35 with the insertion hole 36 to ensure the cell terminal is securely on the cooling platform 31. The cooling platform 31 is positioned corresponding to the cooling section to facilitate heat conduction. Cover the top of the shell body 11 with the cover plate 12, rotate the bolt 16, and the bolt 16 moves downward to engage with the threaded hole 17 until the cover plate 12 is tightly fixed to the shell body 11, ensuring a relatively closed space inside the shell 1, which is beneficial for cooling and monitoring. Start the pump body 24, which draws coolant from the cooling tank 21 through the outlet connector 22. The coolant enters the cooling pipe 25, which is in close contact with the cooling platform 31. The heat generated by the cell terminal is transferred to the cooling pipe 25 through the cooling platform 31. The coolant absorbs heat during its flow in the cooling pipe 25, causing its temperature to rise. Subsequently, the coolant flows back to the cooling tank 21 through the inlet connector 23, where it dissipates heat and cools, completing one cooling cycle and continuously reducing the temperature of the battery cell terminals. Temperature sensor 4 monitors the temperature inside the housing 1 in real time, especially the temperature near the battery cell terminals and the coolant circulation area. The temperature data is transmitted to the display screen 5, allowing staff to visually view the current temperature. When temperature sensor 4 detects that the temperature exceeds a preset safety threshold, it sends a signal to the monitoring alarm 6. Two mirror-symmetrically positioned monitoring alarms 6 sound simultaneously, the sound amplified through the speaker grille 15 to alert staff. A dustproof mesh on the inner wall of the speaker grille 15 prevents dust from entering and affecting the normal operation of the monitoring alarm 6.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
