A cross-sectional view of a part of one embodiment, Fig. 4 shows an IV-IV cross-sectional view, Fig. 5 A is a perspective view of expanded metal, Fig. 5 shows a ■-■ cross-sectional view, and Fig. 6 shows another cross-sectional view. FIG. 3 is a cross-sectional view of the expanded metal of the example. In the drawings, 1 is a heat exchanger tube (flat tube), 1a is a partition wall, 1b is a straight tube part, 2 is a needle fin group, 3 is an expanded metal, 3
a is the strand part, 3b is the bond part, T is the plate thickness, BW is the strand width, LW is the center-to-center distance in the long direction, SW is the center-to-center distance in the short direction, W is the width of the expanded band metal, h
゛ is the wave height after corrugating, and θ is the angle between the longitudinal direction and the straight line after corrugating.

Claims

[Scope of utility model registration request]

In a heat exchanger in which straight pipe sections of flat tubes through which a heat exchange medium flows are arranged substantially parallel to each other, and fins are joined between adjacent hill sections, An expanded metal having needle-like fin groups formed by cutting slits in a staggered manner and enlarging the slits is meandered along its longitudinal direction, and both ends in the width direction are joined to the straight pipe part. A heat exchanger characterized by:
