Directional diversion cooling fin and preparation method thereof

The invention provides a directional diversion cooling fin, which is used in a super capacitor module and comprises a cooling fin shell and a plurality of partition walls. The radiating fin shell is provided with a hollow structure with the periphery closed and the top end and the bottom end open, the hollow structure forms a cavity penetrating through the top end and the bottom end, and the radiating fin shell is attached to the super capacitor single body. The partition walls are arranged in the cavity at intervals to form a plurality of cavity channels, a plurality of airflow inlets are formed in the top end, and a plurality of airflow outlets are formed in the bottom end. The cooling fin is used in a super-capacitor cooling device, the problem that a super-capacitor module is overheated is solved, the performance of a vehicle-mounted energy storage system is greatly improved, stable application of the vehicle-mounted energy storage system is achieved, and reliability, safety and economical efficiency are
