Abstract
The utility model relates to a silencer for a turbo supercharged engine. The silencer comprises a shell and an inner core arranged in the shell, wherein an air channel is arranged in the axial direction of a the inner core shaft; a set of through holes are formed in the peripheral direction of the air channel; a set of a baffles is are further arranged on the outer side of the inner core; a set of mutually-independent inner cavities are formed between the baffles and the inner wall of the shell. According to the silencer provided by the utility model, the noise reduction performance of the silencer can be effectively improved; the silencer is simple in structure, small in volume and low in cost and can be widely applied to the field of automobile engine silencers.
Description
Technical field
The utility model relates to a kind of baffler, relates in particular to a kind of baffler for turbosupercharged engine.
Background technique
Due to the impeller High Rotation Speed of turbosupercharger, the air circle of paddle wheel plane is disturbed.Under the effect of pressure reduction, air is extruded to rear portion by the front portion of blade, produces Gas Vibration, and noise is very strong.It has very wide frequency distribution, take radio-frequency component as main, the increase of its intensity rotating speed and improving rapidly.In order to reduce induction noise, must be at the outlet end design silencing apparatus of pressurized machine.In the baffler of existing design, due to design factor, make erasure effect not perfect, affect driving comfortability.
As Chinese Patent Application No. 200910265360.3 discloses a kind of baffler, comprise suction tude, housing and end socket, in described suction tude, have the inlet hole of a plurality of small pore-like, described suction tude top seal, in described housing, near end socket place, be provided with a fixed dam housing is divided into housing ante-chamber and housing back cavity, on described fixed dam, have many inner tubes and be communicated with housing ante-chamber and housing back cavity, on described housing back cavity, have a plurality of annular slotted holes, the inwall of described baffler is provided with sound-absorbing porous material, the inside of described inner tube is also provided with many group noise reduction tablets, described noise reduction tablet engrail distributes.The present invention adopts sound-absorbing material and bloop, and cost is high, and baffler volume is large, and in baffler, space can not well be utilized.
Model utility content
The purpose of this utility model is to provide a kind of baffler for turbosupercharged engine, solves available engine baffler volume large, the problem that cost is high.
The utility model solves the technological scheme that its technical problem adopts: a kind of baffler for turbosupercharged engine, and comprise housing and be placed in the inner core in housing, along inner spindle to being provided with air flue, along air flue, be circumferentially provided with one group of through hole; The outside of described inner core is also provided with one group of baffle plate, forms one group of separate cavity between baffle plate and inner walls.
For improving noise reduction, described baffle plate is at least provided with 3.
Further, described through hole is for along being axially uniformly distributed of air flue, and through hole is circular hole.
For convenience of installing, on described inner core, be provided with the fixed plate coordinating with shell end, fixed plate is connected with shell end bolt.
The beneficial effects of the utility model: by the cavity structure forming between through hole and baffle plate and inner walls, can greatly reduce the flow velocity that enters gas in baffler, thereby reach the object that reduces noise, simple in structure, and the space in housing is fully utilized, make when reaching the effect of identical noise reduction, less than other baffler volumes, facilitate complete machine to arrange.The Placement of described inner core and housing, simple in structure, easy accessibility.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the sectional view of A-A in Fig. 1.
Fig. 3 is the plan view of inner core.
Embodiment
Embodiment: as shown in Figures 1 to 3, a kind of baffler for turbosupercharged engine, comprises housing 2 and be placed in the inner core 1 in housing 2, be provided with air outlet on housing 2, air outlet is connected with inter cooling pipeline; On inner core 1, be provided with suction port, suction port and pressurized machine are come round.Along inner core 1, be axially provided with air flue 3, along air flue 3 be circumferentially evenly provided with one group of through hole 4, through hole 4 is the circular hole that pore size does not wait; The outside of described inner core 1 is also provided with one group of baffle plate 5, forms one group of separate cavity between baffle plate 5 and housing 2 inwalls.After gas enters the air flue 3 in inner core 1, by through hole 4, enter cavity, thereby reduce the speed of gas flow, reach and fall low noise effect.Described baffle plate 5 is at least provided with 3, has reached good noise reduction.By experiment, at maximum torque point, every meter of inner core can make the noise level 4.5dB(A that declined), reach the effect of having eliminated high-frequency noise.
On described inner core 1, be also provided with the fixed plate 6 coordinating with housing 2 ends, fixed plate 6 is connected with housing 2 end bolt.
