Abstract
A module ensuring an acoustic attenuation of a flow of a first fluid and a heat exchange between the first fluid and a second fluid. The module comprises a perforated first wall with a cutout, a second wall, a cellular structure extending from the second wall to the first wall, a recess provided in the cellular structure between a perforated bottom and a perforated top, and a heat exchanger which is fixed inside the recess between the bottom and the top and in which the second fluid circulates. Such a module ensures an attenuation of sound waves and a heat exchange without limiting the attenuation surface.
Claims10
A module ensuring an acoustic attenuation of a flow of a first fluid and a heat exchange between the first fluid and a second fluid, the module comprising:
- a first wall which is perforated, along which said first fluid flows and which has a cutout,
- a second wall,
- a cellular structure delimiting cells which extend from the second wall to the first wall, and having a first end secured to the second wall and a second end,
- a recess provided in the cellular structure and delimited between a bottom and a top which are perforated, wherein the top closes off the cutout, wherein the bottom extends at a distance from the top, wherein, outside the recess, the second end of the cellular structure is secured to the first wall and wherein, at the recess, the second end of the cellular structure is secured to the bottom, and
- a heat exchanger which is fixed inside the recess between the bottom and the top and in which the second fluid circulates.
