Cooling tube wall is distributed in array.Through-hole 222 and through-hole on first cooling tube, 210 and second cooling tube, 220 tube wall
212 shape, number and spread pattern are all identical.High-temperature gas in first cooling tube 210 and the second cooling tube 220 is through heat exchange
It is discharged respectively from the through-hole 212 and through-hole 222 afterwards, into second shell 120.The heat exchanging silencer uses flat tube conduct
Cooling tube can increase the contact area of high-temperature gas and cryogenic liquid, and the structure of serpentine shaped separation air inlet is used in cooling tube,
The flow velocity of fluid can be improved and enhance disturbance, to improve the heat exchange efficiency of heat exchanging silencer.Cooling tube is vented using aperture
Structure, effective sound deadening can be played.Using the first shorter cooling tube 210 and longer second cooling tube, 220 phase
Mutually setting, and the length difference of the length of the second cooling tube 220 and the first cooling tube 210 is the sound wave half-wavelength that high-temperature gas generates
Odd-multiple, make 210 high temperature gas of the first cooling tube generate sound wave and 220 high temperature gas of the second cooling tube generate sound
Wave interferes at through-hole 212 and through-hole 222, cancels out each other, to reduce noise.Meanwhile the gas being discharged from through-hole 212
Stream liquidates with the air-flow being discharged from through-hole 222, formation, air-flow velocity is reduced, to make reproduced air-flow noise reduce.
Wherein, accommodation space is formed between 210 and second cooling tube 220 of the outer housing and first cooling tube, it is low
The accommodation space that geothermal liquid is formed between first shell 110 and the first cooling tube 210 and the second cooling tube 220 passes through；Heat is handed over
High-temperature gas after changing is emitted into second shell 120 and first through the through-hole on 220 wall of the first cooling tube 210 and the second cooling tube
In the accommodation space formed between cooling tube 210 and the second cooling tube 220.
Two pieces of sealing baffles 130 are arranged radially in the both ends inside the first shell 110, the sealing baffle respectively
130 edge is connect with 210 inner wall sealing of the first shell.Sealing baffle 130 be equipped with 210 outer wall of the first cooling tube and
The through-hole 131 that second cooling tube, 220 outer wall matches, the first cooling tube 210 and the second cooling tube 220 are from the through-hole 131
It passes through, and is tightly connected by the through-hole 131 and the sealing baffle 130.
The heat exchanging silencer further includes rear jam 140, is arranged radially in the end inside the second shell 120
The edge at end, the rear jam 140 is connect with 120 inner wall sealing of the second shell.Jam 140 is equipped with and the second cooling afterwards
The through-hole 141 that 220 outer wall of pipe matches, the second cooling tube 220 are passed through from the through-hole 141, and by the through-hole 141 with
Jam 140 is tightly connected after described.Region of the jam 140 other than crossing with second cooling tube 220 is equipped with multiple logical afterwards
Hole 142.The high-temperature gas to be cooled down in second shell 120 is discharged from the through-hole 142.The heat exchanging silencer is in rear jam
Multiple through-holes 142 are set on 140, so that the gas in heat exchanging silencer is discharged eventually by through-hole 142, further reduced air-flow
Noise.
The first shell 110 is respectively equipped with and 110 connects with the internal cavities of the first shell at the both ends of same side wall
Inlet tube 150 and drain pipe 160.The inlet tube 150 is disposed in proximity to the side of the cooling tube outlet end, the drain
Pipe 160 is disposed in proximity to the side of the cooling tube arrival end, i.e. cryogenic liquid flow direction is opposite with high-temperature gas flow direction.It sets in this way
The flow direction for setting cold fluid and hot fluid enhances liquidating between cold fluid and hot fluid, further improves the high-temperature gas and Low Temperature Liquid
The heat exchange efficiency of body.
The operation principle of the heat exchanging silencer is：The high-temperature gas mean allocation of internal combustion engine discharge enters the first cooling tube
210 and second cooling tube 220 input end, the high-temperature gas from the first cooling tube 210 and the second cooling tube 220 it is snakelike every
Plate part passes through, cryogenic liquid through inlet tube 150 enter first shell 110 and the first cooling tube 210 and the second cooling tube 220 it
Between the accommodation space that is formed, the height in cryogenic liquid and the first cooling tube 210 and the second cooling tube 220 in the accommodation space
Warm gas flow is opposite.Serpentine shaped separation in first cooling tube, 210 and second cooling tube 220 improves the stream of high-temperature gas
Speed simultaneously enhances disturbance, improves the heat exchange efficiency between the high-temperature gas and cryogenic liquid in heat exchanging silencer.And the heat exchange disappears
Sound device high temperature gas and cryogenic liquid flow direction are on the contrary, liquidating between enhancing cold fluid and hot fluid, further improves the high temperature
The heat exchange efficiency of gas and cryogenic liquid.The high-temperature gas completes heat exchanging process with cryogenic liquid in first shell 110
Afterwards, the high-temperature gas to be cooled down in the first cooling tube 210 and the second cooling tube 220 is respectively through multiple through-holes 212 and multiple through-holes
222 enter the accommodation space formed between second shell and the first cooling tube 210 and the second cooling tube 220, and by the high temperature
The cryogenic liquid of gas heating is flowed out through drain pipe 160, and through pipeline to the place for needing thermal energy.Cooling tube uses aperture
The structure of exhaust can play erasure effect.Using the first shorter cooling tube 210 and longer second cooling tube, 220 phase
Mutual arranged for interval, and the length difference of the length of the second cooling tube 220 and the first cooling tube 210 is the high-temperature gas into cooling tube
The odd-multiple of the sound wave half-wavelength of generation makes the sound that 210 high temperature gas of the first cooling tube generates involve the second cooling tube
The noise sound wave that 220 high temperature gases generate interferes at through-hole 212 and through-hole 222, to reduce noise.Meanwhile from
The air-flow being discharged in through-hole 212 and the air-flow being discharged from through-hole 222, formation liquidate, and air-flow velocity are reduced, to make air-flow
Regenerated noise reduces.Finally, high-temperature gas is logical on jam 140 after described after heat exchange is completed in the heat exchanging silencer
Hole 142 is discharged, and the setting of through-hole 142 further reduced pneumatic noise.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
