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. A pressure member 20 is interposed between the heat exchange modules A and B, and this pressure member 20 is an elastic body that pressure-contacts both the fin tubes 3 of one heat exchange module A and those of the other heat exchange module B, and that presses the fin tubes 3 of the respective modules A and B toward a central portion M of the intermediate holding member 11. |
