AI Technical Summary

⚠Technical Problem

Existing water cooling methods pose a risk of leakage when used for extended periods or exposed to vibration, and require electrically driven coolers, leading to unstable heat dissipation of the secondary battery pack.

⚗Method used

Air cooling technology is adopted. By setting inflow and outflow channels in the secondary battery module, heat exchange is carried out through close contact between the heat dissipation structure and the battery cells. Combined with heat dissipation fins and support components, the heat dissipation structure is stabilized to ensure effective cooling even under vibration conditions.

🎯Benefits of technology

It achieves high-efficiency cooling performance under long-term use and vibration environment, avoids the risk of water leakage, and does not require power drive, thus improving the stability and efficiency of heat dissipation structure.
