PROBLEM TO BE SOLVED: To provide a heat exchanger or the like that can appropriately suppress vibration of a plurality of heat transfer tubes.SOLUTION: The heat exchanger includes: a plurality of heat transfer tubes 5 provided side by side with predetermined gaps between them; and a plurality of second vibration suppression members 14B which are provided in the gaps and are provided at both sides of each of the plurality of heat transfer tubes 5 with each of the heat transfer tubes 5 interposed between them. The plurality of second vibration suppression members 14B are arranged in such a manner that the second vibration suppression member 14B on one side and the second vibration suppression member 14B on the other side are arranged with the heat transfer tubes 5 interposed between them and are provided at positions different from each other in an axial direction of the heat transfer tubes 5, the second vibration suppression members 14B on one side are provided so as to press the heat transfer tubes 5 and the second vibration suppression members 14B on the other side are provided so as to press the heat transfer tubes 5 from a side opposite from the second vibration suppression member 14B on one side. |
