Universal attenuation device for air-conditioning circuit

摘要

An attenuation device for a vehicle is provided, including a housing having a chamber formed therein. The housing is coupled to and in fluid communication with an air-conditioning circuit of the vehicle. A dampening member is disposed within the chamber of the housing. The dampening member includes a partition plate having at least one pipe disposed therein. The dampening member is configured to attenuate acoustic energy produced by a fluid of the air-conditioning circuit.

1. An attenuation device, comprising:
a housing having a hollow interior, the hollow interior including at least one chamber, an inlet section having a radially outwardly flared first end, and an outlet section having a radially outwardly flared first end; and a dampening member disposed within the at least one chamber, the dampening member including a partition plate disposed in a substantially orthogonal manner to a longitudinal direction of the at least one chamber, the partition plate having at least one pipe extending therethrough and an outer peripheral surface abutting an inner surface of the housing and forming a first sub-chamber and a second sub-chamber, each of the first sub-chamber and the second sub-chamber longitudinally disposed in the at least one chamber, wherein the first end of the inlet section is directly coupled to both the first sub-chamber and a first end of the at least one pipe and the first end of the outlet section is directly coupled to both the second sub-chamber and a second end of the at least one pipe, wherein the dampening member and the housing are configured to attenuate acoustic energy occurring within a frequency band of about 200 Hz to about 2000 Hz.
