Abstract
An acoustic component is provided with a flow channel for a fluid. The flow channel has an inlet pipe and an outlet pipe. A flow channel section is arranged between the inlet pipe and the outlet pipe, wherein the flow channel section has a silencer volume connected in the flow channel section via openings to the flow channel. A flow deflection device is arranged at least in the flow channel section with the silencer volume, wherein the flow deflection device deflects a flow of the fluid in the flow channel section with the silencer volume away from the openings. The openings in the flow channel section are arranged in a sheltered zone of the flow deflection device.
Claims13
An acoustic component comprising:
- a flow channel for air, the flow channel comprising an inlet pipe, an outlet pipe, and a flow channel section arranged between the inlet pipe and the outlet pipe,
- wherein the flow channel section comprises:
- a cylindrical wall radially surrounding the flow channel where the flow channel extends through the flow channel section;
- a resonator chamber having an air-filled open interior, formed at a radially outer side of the cylindrical wall, the air-filled open interior of the resonator chamber forming a silencer volume,
- wherein the flow channel extends through the flow channel section;
- wherein the silencer volume is connected to the flow channel in the flow channel section via openings formed in the cylindrical wall of the flow channel section;
- a flow deflection device arranged at least in the flow channel section with the silencer volume,
- wherein the flow deflection device comprises at least one step, formed as a step change in a cross section of the flow channel at the at least one step and positioned upstream of the openings, the flow deflection device is configured to deflect a flow of the air in the flow channel section with the silencer volume away from the openings;
- wherein the openings in the flow channel section are arranged in a sheltered zone of the flow deflection device;
- wherein the flow deflection device comprises
- at least one longitudinal stay arranged at a radially inner side of the cylindrical wall radially surrounding the flow channel, the longitudinal stay projecting into the flow channel and extending in an axial direction along a longitudinal axis of the flow channel along the flow channel section.
