Abstract

A cooling fin provides at least a projection part and at least a slot is disposed at lateral sides for the airflow producing turbulent flows while passing through the slot and creating eddy currents at the periphery of the cooling fin. Therefore, the cold air, which flows between a plurality of cooling fins, can stagnate longer time for carrying more heat outward and enhancing the heat dissipation efficiency greatly.
