Air intake silencer

Abstract

An air intake silencer assembly (10) at the intake of an air handling system includes a plenum housing (20) having an inlet (23) end for receiving air and having an outlet port (24) for discharging air. Two baffle panels (28) in spaced relation in the housing define, with the housing, an inlet chamber (30) , a central chamber (32), and a discharge chamber (34) . A plurality of tubular (36) members is supported by the baffle panels (28) and each includes a perforated core (40) and a sound dissipating fiber wrapping (42) . Air flows into the inlet chamber, through the plurality of tubular members to the discharge chamber, and is discharged from the discharge chamber through the outlet port.

Description

[0001] References to other applications [0002] This application claims priority under Title 35, Section 119, of the United States Patent Code to Provisional Patent Application No. 60 / 687,739, filed June 6, 2005, which is hereby incorporated by reference. technical field [0003] The present invention relates to an air intake silencer for attenuating the noise of air flowing into an air handling system, such as an air compressor or blower. Background technique [0004] Air handling systems, such as air compressors or blowers, involve drawing in air from the interface environment. Air in motion, when it reaches the inlet of an air handling system, is subject to changes in air pressure due to the air's interaction with stationary or moving objects. Pressure changes in air manifests, such as sounds, accompanied by annoying or unwanted sounds are broadly defined as noise. Sound propagates at a certain speed through air, other gases and the surrounding medium and reaches the r...

Problems solved by technology

One disadvantage of this method is that it makes the distance between the liner pipe and the air compressor longer, which further increases the noise and leakage at the connecting pipe and hose

Acoustic enclosures, which are supposed to be airtight to reduce internal noise radiation to the external environment, can also cause heat retention problems, complicating the design of acoustic enclosures and increasing their cost by necessitating cooling systems and specific ventilation systems
