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.
Claims18
A structure for providing acoustic attenuation of a flow of a first fluid flowing along the structure, the structure comprising:
- a first wall, which is perforated by a plurality of holes;
- a second wall;
- a plurality of intermediate walls extending between the first wall and the second wall;
- a plurality of corridors defined between adjacent intermediate walls, the corridors being bounded by the first and second walls;
- and
- a pipe configured to receive a second fluid, wherein each pipe is oriented along a length of, and inscribed within, one of the plurality of intermediate walls, and wherein the pipe is located a distance from both the first wall and the second wall;
- wherein the structure is configured for a portion of the first flow to penetrate, via the holes formed in the first wall, into the corridors for heat exchange between the portion of the first fluid in the corridors and the second fluid in a corresponding pipe in one of the intermediate walls defining the corridor.
A structure for providing acoustic attenuation of a flow of a first fluid flowing along the structure, the structure comprising:
- a first wall, which is perforated by a plurality of holes;
- a second wall;
- a plurality of intermediate walls extending between the first wall and the second wall, wherein one or more of the plurality of intermediate walls is in a form of a double wall comprising two parallel walls that extend between the first wall and the second wall and are separated by a free space forming a pipe configured to receive a second fluid;
- and
- a plurality of corridors defined between adjacent intermediate walls, the corridors being bounded by the first and second walls;
- wherein each pipe is oriented along a length of, and inscribed within, a corresponding one of the one or more of the plurality of intermediate walls in which the pipe is formed;
- and
- wherein the structure is configured such for a portion of the first flow to penetrate, via the holes formed in the first wall, into the corridors for heat exchange between the portion of the first fluid in the corridors and the second fluid in a corresponding pipe in one of the intermediate walls defining the corridor.
A structure providing acoustic attenuation of a flow of a first fluid flowing along the structure, the structure comprising:
- a first wall, which is perforated by a plurality of holes;
- a second wall;
- a plurality of intermediate walls extending between the first wall and the second wall, wherein one or more of the plurality of intermediate walls is in a form of a double wall comprising two parallel walls that extend between the first wall and the second wall and are separated by a free space forming a pipe configured to receive a second fluid;
- a plurality of corridors defined between adjacent intermediate walls, the corridors being bounded by the first and second walls;
- a partition wall integral with one or more of the plurality of intermediate walls and extending inside of the pipe and separating the pipe into two sub-pipes;
- and
- fins that extend along the first wall on a side thereof that is opposite the pipe, wherein each fin extends perpendicularly to the one or more intermediate walls and is integral with the first wall,
- wherein each pipe is oriented along a length of, and inscribed within, a corresponding one of the one or more of the plurality of intermediate walls in which the pipe is formed,
- wherein each pipe is located a distance from both the first wall and the second wall.
