Novel efficient low-pressure-drop plate-fin type heat exchanger fin

The invention discloses a novel efficient low-pressure-drop plate-fin type heat exchanger fin. The novel efficient low-pressure-drop plate-fin type heat exchanger fin comprises staggered corrugated fins, wherein the staggered corrugated fins are disconnected and staggered at the end portion of each unit wavelength; the interior of each unit wave is averaged into multiple sections through notches. The novel efficient low-pressure-drop plate-fin type heat exchanger fin has the advantages of having the advantages of staggered fins, corrugated fins and slotted fins at the same time, the degree of turbulence of fluid is stronger in the heat exchange process, a heat exchange boundary layer can be effectively destroyed, and consequently the heat exchange capacity of a heat exchanger is improved greatly. Meanwhile, due to gaps between the fins and the corrugated shape of the fins, flowing resistance of the fluid can be decreased, and the pressure drop in the heat exchange process is not too high.
