RADIATION FIN FOR HEAT EXCHANGER

摘要

PURPOSE: A radiation fin for heat exchanger is provided to prevent the solidified water generated by the radiation operation from being scattered, while achieving an increased efficiency of heat exchanger. CONSTITUTION: A plurality of radiation fins are installed to a radiator of heat exchanger, wherein radiation fins are injection molded into a single unit. The radiation fin has a plurality of cut portions so as to form radiation apertures and a support portion. A plurality of radiation slits are formed at the support portion so as to achieve an increased radiation efficiency and prevent solidified water from being formed at the support portion. Each of radiation portions formed at an end of the radiation aperture, has a cut portion, and the cut piece is bent upward or downward, to thereby form a drain portion by the cut portion and cut piece. The solidified water formed at the surface of the radiation fin is drained through thus-formed drain portion.
