Novel plate -fin type heat exchanger fin

The utility model discloses a novel plate -fin type heat exchanger fin comprises plain fin and 14 spherical inclusions, and at first crack on the slab through the cutter, then go out alternately protruding with sunkenly to be the 14 spherical inclusions that the square was arranged through the mould punching press, last rolling forming, its main structural parameters includes: fin height h (i) f (i), fin thickness delta (i) f (i), interval s in the wing (i) f (i), 14 spherical inclusion radius R, i), (i) (the inclusion leaves b to the fin back gauge (i) f is (i) f adjacent inclusion interval c, this novel plate -fin type heat exchanger fin supports through the baffle between the adjacent fin, and sealed through the sealing strip between the baffle, the fluid flows into along perpendicularinclusion opening orientation, its special construction can realize suitable, contrary, hand over stranded such as cross -flow to flow, when fluid flow warp or entering inclusion, not only can improvethe local velocity, the a
