。 A plurality of U-shaped U-pipes are regularly arranged side by side with their U-shaped bent ends facing one direction, and the adjacent connecting opening ends of these U-pipes are connected to each other by a U-shaped return bend. These U-pipes are successively connected, and on the outer periphery of each U-pipe there is a two-hole fin that is fitted and fixed externally across the straight pipes of each U-pipe, and a two-hole fin that is externally fitted and fixed between the straight pipes of the adjacent U-pipes. 2 for fixed connection
Hole fins are arranged alternately at a required pitch in the axial direction of these straight pipe parts, and a single hole fin is arranged on the outer periphery of the straight pipe part of the U-pipe at the outer end in the arrangement direction of the two-hole fins for connection. A heat exchanger characterized by being fitted and fixed.
