Fin for a one-piece heat exchanger and method of manufacturing the fin |
摘要 |
The present invention provides fins utilized in an integrated heat exchanger that achieve a highly effective prevention of heat conduction, do not create any cuttings during their formation and achieve a high degree of dynamic strength and a method for manufacturing these fins. The fins are each provided with a heat transfer prevention portion at the apex located between tubes of adjacent heat exchangers and the fins are formed by implementing, at least, a slit formation step in which at least a pair of slits are formed over specific intervals at an approximate center of a fin material achieving a specific width along the direction of the width, a corrugating step in which the fin material is bent to achieve a corrugated shape so that the pair of slits are at the apex of the fin material along the direction in which the fin material advances, a heat transfer prevention portion formation step in which a heat transfer prevention portion is formed by folding the area between the pair of slits forming the apex portion to the opposite direction from the apex portion and a crest cutting step in which the corrugated fin material is cut to achieve a specific number of crests.
