Abstract
A structure ensuring acoustic attenuation of a flow of a first fluid and heat exchange between a first fluid and a second fluid. The structure includes a first wall which is perforated, a second wall, and a plurality of intermediate walls extending between the first wall and the second wall. For each intermediate wall, there is a pipe intended to receive the second fluid and inscribed within the intermediate wall. Such a structure makes it possible to optimally integrate the acoustic wave attenuation function and the heat exchange function.

A structure providing acoustic attenuation of a flow of a first fluid and heat exchange between the first fluid and a second fluid, the structure comprising:
- a first wall which is perforated;
- a second wall;
- a plurality of intermediate walls extending between the first wall and the second wall;
- and
- for each of the intermediate walls, a pipe to receive a second fluid and inscribed within the intermediate wall, and wherein the pipe is located a distance from both the first wall and the second wall.
A structure providing acoustic attenuation of a flow of a first fluid and heat exchange between the first fluid and a second fluid, the structure comprising:
- a first wall which is perforated;
- a second wall;
- a plurality of intermediate walls extending between the first wall and the second wall;
- and
- for each of the intermediate walls, a pipe to receive a second fluid and inscribed within the intermediate wall, wherein the intermediate wall has a form of a double wall comprising two parallel walls extending between the first wall and the second wall and separated by a free space forming the pipe.
A structure providing acoustic attenuation of a flow of a first fluid and heat exchange between the first fluid and a second fluid, the structure comprising:
