Claims

[Scope of utility model registration request]

It consists of a large number of fins arranged in parallel at predetermined intervals, a group of heat exchange tubes that pass through these fins, and a U-bend portion that connects the ends of the group of heat exchange tubes to form a flow path. In the heat exchanger, each fin located between the heat exchange tubes is provided with a pair of cut-and-raised pieces facing each other, and the pair of cut-and-raised pieces are arranged so that the free ends of the pair of cut-and-raised pieces join together. A heat exchanger characterized in that it is bent to form a triangular projection, and the triangular projection is used as a spacer between each fin.
