Fin-and-tube heat exchanger, an air conditioner having the same, and a method for manufacturing fin and tube type heat exchanger

摘要

PROBLEM TO BE SOLVED: To suppress deformation of a fin shape by biting fins with each other in taking out a lamination fin.;SOLUTION: A fin and tube type heat exchanger includes a plate-like fin 17 laminated with a constant interval, and a heat transfer pipe 3 inserted into the laminated plate-like fin 17. At the edge of at least one of both side parts of each laminated plate-like fin 17, fin intrusion control means 15, 16 are formed at a plurality of places, which prevent adjacent lamination fin 2 from intruding into a gap between plate-like fins 17 laminated at manufacturing.;COPYRIGHT: (C)2014,JPO&INPIT
