Device for reducing the vibrations of a tube bundle of a heat exchanger inside its shell

A device for reducing vibrations of a tube core inside a shell of a heat exchanger, wherein said tube core includes a main face and two side faces adjacent to the main face, and at least one linking part between tubes of the tube core giving rise to a protrusion in the main face and the two side faces, and wherein the device comprises:

• a first section adapted to be arranged on the main face and two second sections adapted to be arranged on the two side faces, wherein each second section extends from a different end of the first section and the two second sections are arranged in opposition to one another, such that the first section and the second sections in combination form a “U” shape;
• at least one anchor arranged in each section and oriented toward the inside of the “U” shape formed by the first section and the second sections in combination, wherein each anchor is adapted to receive a protrusion formed by the at least one linking part between tubes of the tube core;
• and
• at least one elastically deformable support element arranged in each section and oriented toward the outside of the “U” shape formed by the first section and the second sections in combination, wherein the at least one elastically deformable support element is adapted to be supported against at least one inside surface of the shell of the heat exchanger;
• wherein each second section of the two second sections comprises a retaining clip, and the retaining clips of the two second sections operate in opposition to one another to retain the device on the tube core.
