Claims

[Scope of utility model registration request]

(1) A large number of elongated holes 1 for fluid circulation are bored in the metal plate spaced apart from each other in the width direction and the longitudinal direction, and the metal plate is cultured at substantially both ends of the elongated holes 1 along its long axis. The fin of the heat exchanger is formed by bending a plate to form a zigzag shape, and the long axis of the long hole 1 is positioned in the direction in which the culm rises.

(2) A large number of long holes 1 are bored in parallel with each other, and a large number of inter-long hole metal parts 2 existing between adjacent long holes 1 in the width direction of each long hole 1 are drilled one after another. The fin according to claim 1, which is a registered utility model, wherein the fin is formed in an uneven manner so that the elongated hole 1 expands in the thickness direction of the metal plate.

(3) The fin according to claim 1, which is a registered utility model, in which both longitudinal edges of the elongated hole 1 are formed by a single smooth line.
