Wavy fin, heat exchanger having the same, apparatus for manufacturing the same, method for manufacturing the same and computer recordable medium storing the method
View Patent ↗Disclosed herein are a wavy fin, a heat exchanger having the same, an apparatus for manufacturing the same, a method of manufacturing the same, and a computer-readable recording medium storing the method. The wavy fin is configured such that top and bottom parts are alternately formed in a width direction while being connected by side parts, and the top, bottom, and side parts extend in a longitudinal direction so as to form a wave such that ridges and valleys are alternately repeated, and includes a front part in front of each ridge or valley of the wave in the longitudinal direction, and a rear part beyond the ridge or valley of the wave in the longitudinal direction. The front and rear parts are offset from each other in the width direction so as to be misaligned at the ridge or valley of the wave.
1. A wavy fin, in which a plurality of top and bottom parts forming ridges and valleys are alternately formed in a width direction while being connected by a plurality of side parts, and the top parts, the bottom parts, and the side parts extend in a longitudinal direction so as to form a wave such that ridges and valleys are alternately repeated, the wavy fin comprising:
a front part as a region in front of each ridge or valley of the wave in the longitudinal direction; and
a rear part as a region beyond the ridge or valley of the wave in the longitudinal direction,
wherein the front and rear parts are offset from each other in the width direction so as to be misaligned at the ridge or valley of the wave, wherein one of the front and rear parts is offset from the other within a width between adjacent side parts, and wherein the wave has a herringbone shape or a sinusoidal shape.
2. The wavy fin according to claim 1 , wherein one of the front and rear parts is offset from the other by ½ of a width between adjacent side parts.
3. The wavy fin according to claim 1 , wherein one of the front and rear parts is offset from the other by ⅓ of a width between adjacent side parts.
