Document Type and Number:
WIPO Patent Application WO/2018/092355
Kind Code:
A1
Abstract:
The present invention relates to a vibration damping structure for a heat transfer tube group that has an array of a plurality of spaced-apart columns (5A), which comprise an array of a plurality of heat transfer tubes (5) parallel to each other and curved on a common surface. First vibration suppression members (14A) and second vibration suppression members (14B) which are provided between the N-th column and the (N+1)th column so as to cross each other in the array direction of the columns are arranged at positions different from each other in the axial direction of the heat transfer tubes, and have a thickness in the array direction larger than the average of the spaces between the columns during operation.
