Description
Technical field
The present invention relates to automotive muffler field, more specifically to a kind of height in vehicle intercooler air inlet pipe
Frequently acoustic filter.
Background technology
Along with turbocharging technology application in automobile engine, while improving vehicle dynamic quality, turbine produces
Utter long and high-pitched sounds, surge high-frequency noise more and more prominent, and be gradually increasing the main contributions source into internal car noise.This noise frequency master
In the range of 1200Hz-2500Hz to be concentrated on, have even reaches 3000Hz, and frequency coverage is the widest.How to reduce turbine work
During work produce utter long and high-pitched sounds, surge noise improve automobile sound quality be particularly important.At present, the side of high-frequency noise is solved
Formula mainly has following several:
(1) adding multiple (usual four) quarter-wave long tube on air inlet tube of cooler, quarter-wave long tube is an end seal
Closing the pipe of one end perforate, it together forms collateral branch's type acoustic filter with air inlet tube of cooler.
(2) see Fig. 5, air inlet tube of cooler 1 is arranged side by side three resonant cavities (can also be more than three) with shape
Becoming high-frequency resonant cavity, each resonant cavity is connected with air inlet tube of cooler by the radially little round tube hole of a group on air inlet tube of cooler,
The soundproof effect of high-frequency resonant cavity is substantially better than quarter-wave long tube, and without by frequency, the quantity of its resonant cavity determines
The quantity of noise elimination peak value, and radially the volume of the diameter of little round tube hole, quantity and resonant cavity has together decided on single noise elimination peak value
Bandwidth, the number of resonant cavity is the most, and the quantity of noise elimination peak value is the most, can widen noise elimination bandwidth to a certain extent；If
Keep former resonant cavity number constant, in the case of increasing axial length (i.e. chamber length), optimize quantity and the Kong Zhi of little round tube hole
Footpath, it is possible to widen noise elimination bandwidth to a certain extent, but this high-frequency resonant cavity also can be limited by Arrangement of Engine-room, its footpath
In the range of certain size, thus chamber number and the quantity of little round tube hole of resonant cavity can only be affected to size and axial length, make
Its noise elimination frequency band can not cover the frequency range of needs well, does not has good noise elimination effect.
Summary of the invention
It is an object of the invention to provide a kind of high frequency acoustic filter in vehicle intercooler air inlet pipe, it can be limited
Cabin space in so that it is noise elimination frequency band is wider, and acoustic attenuation performance is excellent, more effectively reduces and produces during turbocharger operation
Raw utter long and high-pitched sounds, the high-frequency noise such as surge.
High frequency acoustic filter in vehicle intercooler air inlet pipe of the present invention, including air inlet tube of cooler, in cold
In device air inlet pipe connect have main pipeline, be provided with an opening vertically in the side of main pipeline tube wall, this opening part be provided with in
The housing of cavity body structure, housing, by this closure of openings, is disposed radially the dividing plate that polylith is axially spaced apart in housing,
Making in closed housing body to be axially formed multiple resonant cavity along main pipeline, resonant cavity connects with main pipeline.
Further, being equipped with PEEK film in resonant cavity and main pipeline connectivity part, PEEK film can effectively reduce air-flow to altogether
Shake the impulsive force of cavity wall, be greatly reduced due to high frequency acoustic filter when the gas handling system abnormal sound problem that cause.
Further, dividing plate quantity is seven, makes in closed housing body to be axially formed eight resonant cavities along main pipeline.
Further, main pipeline is provided with fixed support, it is not necessary to additionally increase mount point, and moulding is neat and artistic.
High frequency acoustic filter in vehicle intercooler air inlet pipe of the present invention, owing to having said structure, closes housing collection
Becoming in turbocharger air inlet pipe side, the size of this structure is little, is limited little by Arrangement of Engine-room requirement, it is possible in limited cabin
Increasing the number of resonant cavity in space, its frequency of noise elimination characteristic matches with the frequency characteristic of turbocharger noise, and has foot
Enough sound deadening capacities, multiple resonant cavities broaden the noise elimination bandwidth of sound transmission loss so that it is covering frequence increases, and disappears with existing high frequency
Noise elimination bandwidth and the sound deadening capacity being greatly improved sound transmission loss compared by sound device, and acoustic attenuation performance is excellent, comes from turbocharger
The air whirl noise produced, runs into the cross section of multiple acoustic impedances sudden change that this structure is formed, multiple reflections occurs, constantly disappears
Energy consumption, thus produce during effectively reducing turbocharger operation utter long and high-pitched sounds, the high-frequency noise such as surge, improve vapour
The sound quality of car.

Detailed description of the invention
In order to technical scheme is explained further, come that the present invention will be described in detail below in conjunction with the accompanying drawings.
Seeing shown in Fig. 1 to Fig. 3, this is used for the high frequency acoustic filter in vehicle intercooler air inlet pipe, including charge air cooler air inlet
Pipe 1, connects on air inlet tube of cooler 1 and has main pipeline 2, be provided with an opening vertically in the side of main pipeline tube wall, open at this
Being provided with the housing 4 in cavity body structure at Kou, housing 4, by this closure of openings, has been disposed radially polylith vertically in housing
Spaced apart dividing plate 5, makes the interior multiple resonant cavity that is axially formed along main pipeline of closing housing 4, and resonant cavity is with main pipeline 2 even
Logical.It is equipped with PEEK film 15 in resonant cavity and main pipeline connectivity part.Main pipeline 2 is provided with fixed support 6.The present embodiment
In, dividing plate 5 quantity is seven, make in closing housing 4 along main pipeline be axially formed first resonant cavity the 7, second resonant cavity 8, the
Three resonant cavity the 9, the 4th resonant cavity the 10, the 5th resonant cavity the 11, the 6th resonant cavity the 12, the 7th resonant cavity the 13, the 8th resonant cavities 14.
Shown in Figure 4, come from the air whirl noise that turbocharger produces, run into multiple sound that this structure is formed
, there is multiple reflections, continuous consumed energy in the resonant cavity of change in the instantaneous impedance, thus effectively reduce utter long and high-pitched sounds, the high-frequency noise such as surge.
Through CAE acoustics simulation calculation, finally design analytical calculation obtains sound transmission loss curve as shown in Figure 4, a in figure, b, c, d,
The noise elimination peak value of the most corresponding first, second, third, fourth, the five, the six, the seven, the 8th resonant cavities of e, f, g, h；With 20dB
