AI Technical Summary
The heat generated during the charging and discharging process of composite batteries can lead to excessively high temperatures, affecting battery life and safety. Furthermore, battery activity decreases and output power is insufficient in low-temperature environments.
A composite battery heat exchanger was designed, comprising a heat dissipation mechanism and a heat exchange mechanism. A fan accelerates airflow, which enters the heat dissipation box through a breathable grid, then enters the mounting box through the air inlet and air inlet pipe. After contacting the heat exchange mechanism, the heat is carried away and discharged. Combined with the connecting air pipes of the ring array, the contact area is increased, achieving rapid heat dissipation and heat conversion.
It effectively avoids heat accumulation, reduces the impact of high battery temperature on lifespan and safety, improves heat dissipation efficiency, prevents thermal runaway, and ensures stable battery performance under different temperature environments.
