Abstract
The utility model discloses a novel automobile silencer, comprising a shell and a gas inlet pipe and a gas outlet pipe which are welded in the shell, wherein the shell is made of aluminium magnesium alloy; and the gas inlet pipe and the gas outlet pipe are also made of aluminium magnesium alloy. The novel automobile silencer has the advantages that due to the adoption of the aluminium magnesium alloy, the heat conduction property is good, the heat dissipation effect is good, breakage does not easily occur, the ductility is good, the machining is convenient, resonance is low, the silencing effect is good, and the service life is long.
Description
Technical field
The utility model relates to a kind of automotive muffler, and specifically a kind of New Type Material automotive muffler belongs to the automotive muffler field.
Background technique
Automotive muffler is automobile constituent elements commonly used, is conducive to reduce the noise pollution in the vehicle traveling process, utilizes sound wave stack principle of interference to be made.Automotive muffler can be divided into reactive muffler, dissipative muffler and impedance composite muffler three classes by noise-cancelling theory and structure.Automotive muffler can reduce the exhaust sound of motor, and high-temp waste gas can be discharged safely and effectively.Silencing apparatus should guarantee that as the part of exhaust duct its exhaust is unimpeded, resistance is little and sufficient intensity.Silencing apparatus will stand 500 ℃～700 ℃ high-temperature exhaust airs, guarantees not damage, do not lose soundproof effect in the distance travelled of automobile regulation.Yet, most of automotive muffler with snowflake iron, stainless steel in the market.Snowflake iron automotive muffler: eliminate the noise all right, but corrosion-resistant easily is corroded, working life is short; The stainless steel automotive muffler: resonance is strong, and soundproof effect is poor, poor thermal conductivity, and the cold and hot temperature difference is large, easily fracture.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of Novel automobile muffler, and by adopting the aluminum-magnesium alloy material, thermal conductivity is good, good heat dissipation effect, and easy-rupturing not, ductility is good, and is easy to process, Hyporesonance, soundproof effect is good, long service life.
The technical solution of the utility model is:
A kind of Novel automobile muffler comprises housing, and is welded on suction tude and steam outlet pipe on the described housing, and described housing is the housing of aluminum-magnesium alloy, and described suction tude and steam outlet pipe are aluminum-magnesium alloy tube.
Further, be provided with aluminum-magnesium alloy dividing plate with holes in the described housing, described dividing plate is provided with one or some, and housing is divided into several chambers, improves further erasure effect by dividing plate.
Further, described enclosure interior also is provided with the porous inner tube that connects described suction tude and steam outlet pipe, and described inner tube is aluminum-magnesium alloy tube, and described inner tube is passed described dividing plate, the tube wall of described inner tube is provided with some pores, and the axis of described pore tilts along airflow direction.
Further, described steam outlet pipe is provided with the noise elimination through hole at the tube wall near this steam outlet pipe mouth of pipe place, and this noise elimination through hole is communicated with ambient atmosphere, can reduce the quadratic noise that produces in the steam outlet pipe.
The utility model has the advantage of: by adopting the aluminum-magnesium alloy material, thermal conductivity is good, good heat dissipation effect, and easy-rupturing not, ductility is good, and is easy to process, Hyporesonance, soundproof effect is good, long service life.
The utility model is described in further detail below in conjunction with drawings and Examples.
