Claims (1)

[Claims for Utility Model Registration] (1) A heat exchange tube that has multiple rows of fluid passages for refrigerant, etc. and is bent in a meandering manner, and heat that is interposed in the gap between adjacent parts of this heat exchange tube. What is claimed is: 1. A heat exchanger comprising replacement fins, wherein at least one of the heat exchange tube and the fin is provided with a protrusion for preventing fin displacement that engages with the other. (2) The heat exchanger according to claim 1, wherein projections for preventing fin displacement are discontinuously formed at the contact portion between the heat exchange tube and the heat exchange fin.
