Claims

[Scope of utility model registration request]

A large number of fins 2, 2... are commonly used orthogonal to a large number of heat transfer tubes 1.1... arranged in parallel, and the front and rear numbers of the heat transfer tube insertion portions 3, 3... of each fin 2 are In a heat exchanger in which a large number of cut and raised pieces 4, 4, . The side end portions 2b are located before and after the fins 2 at least at the positions that are the side end portions 2b, 2b of each fin 2.
, 2b are integrally formed with ribs 6, 6, . . . to reinforce the bending strength of the heat exchanger.
