Background technology
Reactive muffler noise elimination frequency band is limited, generally to it is low, midband soundproof effect is good, high frequency soundproof effect is poor, lorry
Use reactive muffler more.Sound-absorbing material come abating noises, is fixed on air-flow stream by dissipative muffler mainly with sound-absorbing material
Logical inner-walls of duct or by certain way arrangement in the duct, when sound wave enters silencer, most of acoustic energy is absorbed, and is played
Noise elimination acts on.The advantages of dissipative muffler is to be eliminated the noise in the range of wider medium-high frequency, is especially had to high frequency sound wave prominent
Noise elimination acts on, and shortcoming is in high-temperature vapor and has service life in the gas of corrosion function shorter to sound-absorbing material.It is existing
Silencer it is more both are combined to carry out noise reduction, but noise reduction over the entire frequency band is not still very good, or
To obtain preferable soundproof effect, the volume of silencer is excessive, is not easy to install.It is therefore desirable to provide a kind of new noise elimination
Device is to solve above-mentioned technical problem.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided one kind can obtain over the entire frequency band
Obtain the pollution of preferable soundproof effect, reduction tail gas to environment reduces carrying for influence of the delivery temperature to Muffler Performance simultaneously
The automotive muffler of catalyst converter and cooler.
According to technical scheme provided by the utility model, the automotive muffler with catalyst converter and cooler, including
Cooler, ventilative noise absorption cover, catalyst converter, air inlet supervisor, air inlet end cap, tubular shell, built-in silencer, outlet end cap and outlet
Supervisor；Air inlet end cap is fixed with inside the left end of tubular shell, outlet end cap is fixed with inside the right-hand member of tubular shell,
Inlet end, which covers, is fixed with air inlet supervisor, is covered in outlet side and is fixed with outlet supervisor, fixed on the right side wall of air inlet end cap
There is ventilative noise absorption cover, ventilative noise absorption cover covers the air inlet supervisor on the right side of air inlet end cap, the tubular shell in ventilative noise absorption cover
Catalyst converter, cooler and built-in silencer are sequentially installed with from left to right on interior air inlet supervisor.
Supporting plate is installed, the other end of supporting plate, which is arranged on, breathes freely on the air inlet supervisor between catalyst converter and cooler
On noise absorption cover.
The built-in silencer includes first partition, second partition, the 3rd dividing plate, the 4th dividing plate, noise elimination air inlet pipe, noise elimination
Connecting tube and noise elimination escape pipe；The left part of noise elimination air inlet pipe is fixed in first partition, and the right part of noise elimination air inlet pipe is fixed
On second partition, the left part of two noise elimination connecting tubes is fixed on second partition, in the right part peace of two noise elimination connecting tubes
Equipped with the 3rd dividing plate, the left part of noise elimination escape pipe is fixed on the 3rd dividing plate, and the right part of noise elimination escape pipe is fixed with the 4th
Dividing plate.
The utility model arranges a catalyst converter to reduce the pernicious gas in exhaust, the cloth after catalyst converter after air inlet pipe
A cooler is put to be lowered into the temperature of built-in silencer gas, reduces influence of the temperature to Muffler Performance.This practicality
It is new using resonant cavity, more perforated pipes and sound-absorbing material reduce the noise in whole frequency domain.
