A heat exchanger fin and a heat exchanger tube having the same are provided to facilitate heat exchange between fluids flowing inside and outside the heat exchanger tube by increasing heat transfer area, and to allow various arrangement of the heat exchanger tube in the process of designing a heat exchanger. A heat exchanger fin(100), which is attached onto an outer periphery of a heat exchanger tube within a housing of a heat exchanger that absorbs ambient heat or dissipates heat, comprises a cylindrical connection part(110), a disk-like flange part(120), and a filler metal mounting part(140). The connection part has a predetermined width to make face contact to the outer periphery of the heat exchanger tube. The flange part extending from one end of the connection part in radial direction, having a plurality of embossments(130) formed like a dome with an outside open, whose top position is lower than the width of the connection part, at a predetermined gap(132) between each embossment. The filler metal mounting part is grooved on the flange part to mount a filler metal for brazing of the outer periphery of the heat exchanger tube and the connection part. |
