Description
Technical field
The utility model is related to silencer technical field, more particularly to a kind of novel Hull nurse hereby high frequency silencer.
Background technology
With being constantly progressive for automobile industry, the requirement to NVH is continuously improved, and then the work of muffler of automobile exhaust system
With ever more important, the primary and foremost purpose of silencer is to eliminate noise, therefore to meet acoustical demands.Gas is transported in air inlet system and exhaust system
It is dynamic, and must satisfy the requirement of air flowing, the in addition also requirement of material, installation space etc..
At present, traditional silencer is short of in terms of taking into account low-frequency noise and high frequency noise.Some silencer schemes
It reduces low frequency noise and increases high frequency noise, some are then opposite.Current automotive muffler is limited to space layout, substantially
All it is to use single structure, it is difficult to take into account the noise of full frequency band, so exhaust noise is difficult to be controlled, and increases manufacture
Cost.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of novel Hull nurse hereby high frequency noise elimination
Device.
The utility model is to solve above-mentioned technical problem by following technical proposals：
Hereby high frequency silencer, feature are a kind of novel Hull nurse of the utility model offer comprising shell, inlet end
Lid, outlet end cap, air inlet pipe, escape pipe, intermediate tubule and high-frequency tube, the both ends of the shell be occluding with respectively the air inlet end cap and
The outlet end cap is fixed with first partition and second partition in the shell, which is divided into cavity I, cavity II and cavity
III, the first partition are porous barrier, which is non-porous separator plate, the air inlet pipe by the air inlet end cap wear this
One partition board simultaneously extends between the first partition and the second partition, and the outlet end of the air inlet pipe offers multiple apertures,
One end of the intermediate tubule is inserted in the air inlet pipe, the other end wears the second partition and extends to the second partition and this goes out
Between gas end cap, cavity III is made to form a Hull nurse hereby chamber；
The escape pipe wears the first partition and the second partition and penetrates through the outlet end cap, the escape pipe be located at this second
It is offered on the wall of section on close hole and the wall between partition board and the outlet end cap and is arranged with the high-frequency tube.
Preferably, the intermediate tubule is inserted in 5mm in the air inlet pipe.
Preferably, the intermediate tubule is fixedly connected with the high-frequency tube by connector.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can arbitrarily combine to get the utility model respectively compared with
Good example.
The positive effect of the utility model is：
The utility model preferably takes into account low frequency and high frequency noise in capable of arranging in a limited space, using novel conspicuous
Er Muzi high frequency silencers can efficiently control exhaust low-and high-frequency noise.
Description of the drawings
Fig. 1 is the structural schematic diagram of the novel Hull nurse hereby high frequency silencer of the utility model preferred embodiment.
Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained without making creative work all belong to
In the range of the utility model protection.
As shown in Figure 1, the present embodiment provides a kind of novel Hull nurse hereby high frequency silencers comprising shell, air inlet end cap
1, outlet end cap 8, air inlet pipe 5, escape pipe 6, intermediate tubule 4 and high-frequency tube 7, the both ends of the shell are occluding with the inlet end respectively
Lid 1 and the outlet end cap 8 are fixed with first partition 2 and second partition 3 in the shell, which are divided into cavity I, cavity
II and cavity III, the first partition 2 are porous barrier, which is non-porous separator plate, which passes through the inlet end
Lid 1 wears the first partition 2 and extends between the first partition 2 and the second partition 3, and the outlet end of the air inlet pipe 5
Multiple apertures are offered, one end of the intermediate tubule 4 is inserted in 5mm, the other end in the air inlet pipe 5 and wears the second partition 3 simultaneously
It extends between the second partition 3 and the outlet end cap 8, cavity III is made to form a Hull nurse hereby chamber.
The escape pipe 6 wears the first partition 2 and the second partition 3 and penetrates through the outlet end cap 8, passes through the outlet end cap
8 gas is discharged, which, which is located between the second partition 3 and the outlet end cap 8, offers close hole and the wall on the wall of section
On be arranged with the high-frequency tube 7, which is fixedly connected with the high-frequency tube 7 by connector.
For air-flow after the inflow of air inlet pipe 5, a part of air-flow enters III Hull nurse of cavity hereby chamber by intermediate tubule 4, eliminates
Part low frequency noise, another part air-flow is flowed by the aperture of the outlet end of air inlet pipe 5 in II expansion cavity of cavity, then is passed through
Process in first partition 2 flows back into cavity I, enters back into escape pipe 6, and the high-frequency tube 7 by being installed additional outside escape pipe 6
It is discharged after eliminating high frequency noise.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make these embodiments numerous variations or repair under the premise of without departing substantially from the principles of the present invention and essence
Change, but these change and modification each fall within the scope of protection of the utility model.
