Abstract: The heat exchanger includes: a plurality of heat transfer tubes which is arranged and provided with predetermined gaps; and a plurality of second vibration suppression members 14B which is provided in the gaps and is provided on both sides sandwiching each of the heat transfer tubes 5, and one second vibration suppression member 14B and the other second vibration suppression member 14B of a plurality of second vibration suppression members 14B are provided at different positions in an axial direction of the heat transfer tubes 5 sandwiching the heat transfer tubes 5, the one second vibration suppression member 14B is provided pressing the heat transfer tubes 5; and the other second vibration suppression member 14B is provided pressing the heat transfer tubes 5 from an opposite side of the one second vibration suppression member 14B.

Abstract: It is intended to provide a vibration control apparatus that can be installed in a small pace and can be produced at low cost, as well as a wind turbine generator equipped with the vibration control apparatus and a vibration control method. The vibration control apparatus 7 includes a first vibration system 10 of inverted-pendulum type, second vibration systems 20 of inverted-pendulum type which are provided on both sides of the first vibration system 10, a restraining unit 30 which restrains a first weight 11 of the first vibration system 10 and a second weight 21 of the second vibration system 20 and a damper which damps vibration of the first weight 11 and the second weight 21. The vibration control apparatus 7 is installed on an upper floor 8a of a plurality of floors 8.
