This utility model discloses a multi-directional heat dissipation fin structure for a
power battery terminal, including a mounting base and a heat dissipation fin
assembly. The mounting base is a hollow cylindrical structure for fitting into the terminal. At least two heat dissipation fin assemblies are provided. These fin assemblies are evenly spaced from top to bottom on the outer wall of the
bushing, creating horizontal gaps between adjacent fin assemblies for
airflow. Each heat dissipation fin
assembly consists of multiple fins, which are evenly distributed circumferentially on the outer wall of the mounting base, creating vertical gaps between adjacent fins for
airflow. This increases
airflow efficiency while maintaining sufficient heat dissipation area, effectively reducing the terminal temperature and ensuring battery performance and safety.
