PROBLEM TO BE SOLVED: To prevent abnormal wear by vibration of fin tubes in insertion holes of an intermediate holding member, with a simple configuration.SOLUTION: A fin tube heat exchanger is configured so that a plurality of heat exchange modules A and B are coupled to each other, the heat exchange modules A and B each comprising: a plurality of fin tubes 3 each including a plurality of flange fins 6 axially and continuously attached onto an outer circumferential surface of a heat transfer tube 5; and an intermediate holding member 11 in which a plurality of insertion holes 12 are formed, the fin tubes 3 being inserted into the insertion holes 12, respectively, the fine tubes 3 being gathered on each intermediate member 11 by being inserted into the respective insertion holes 12. Linear tube-vibration-control members 20 are provided to stride over coupling portions of the heat exchange modules A and B (matching portions 11a of the intermediate holding members 11) and to obliquely passing between the fin tubes 3 in an axial view of the fin tubes 3. The plurality of tube-vibration-control members 20 is provided so as to have an area covering the coupling portions of the heat exchange modules A and B and to cross one another in an X-shaped fashion. |
