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 and cryogenic liquid complete heat exchanging process 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, the sound for generating 210 high temperature gas of the first cooling tube 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 in blocking film 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.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
