Novel plate -fin type heat exchanger fin

The utility model discloses a novel plate -fin type heat exchanger fin, constitute by the two triangle -shaped scales of opening of plain fin and theta angle, at first crack on the slab through the cutter, then be the two triangle -shaped scales of opening in theta angle that the square was arranged through mould punching press play order is protruding sunken, last rolling forming, this novel plate -fin type heat exchanger fin, support through the baffle between the adjacent fin, it is sealed through the sealing strip between the baffle, the fluid flows into along perpendicular scale opening orientation, its special construction can realize arranging, it is contrary, strandeds such as friendship cross -flow flow, when fluid flow warp or entering scale, not only can improve the local velocity, the attenuate boundary layer, increase temperature gradient, and produce strong disturbing action, improve its comprehensive properties, the whole appearance of this novel fin is the same with ordinary fin, has higher co
