Efficient plate fin type heat radiator fin

The invention provides an efficient plate fin type heat radiator fin, which comprises a separation plate and unit fins arranged on the separation plate, wherein the unit fins are uniformly arranged on the separation plate in rows and in lines, each unit fin is of a V-shaped structure, in addition, at least six cylindrical turbulent flow elements are uniformly arranged on the V-shaped outer side surface of each unit fin, the total area of the turbulent flow elements is 15 percent to 20 percent of the area of each unit fin, the arrangement modes of every two rows of unit lines are identical, the unit fins in every two adjacent lines are in uniform and staggered arrangement, and in addition, the staggering positions are the end parts of the unit fins. The efficient plate fin type heat radiator fin has the advantages that the turbulent flow elements are arranged on the surfaces of the fins, the surface roughness of the fins is increased, when fluid impacts the turbulent flow elements, eddy current is formed near the turbulent flow elements, the fluid turbulence degree is increased, the heat boundary layer is damaged, and the heat exchange is further enhanced.
