Cooling tube is inside interspersed with, the coolant for being connected with and constantly flowing is connected in the cooling tube, is equipped with the noise reduction unit and diversion division
The recoil groove that end is oppositely arranged, track of the recoil groove outer rim tangential direction after the discharge of diversion division end exhaust gas, institute
State noise reduction unit side wall and be equipped with exhausting-gas hole.
As a preferred mode, the diversion division inner cavity is equipped with spiral flow deflector.
As a preferred mode, it is surrounded with noise elimination baffle on the outside of the diversion division end.
As a preferred mode, the recoil groove inner wall is equipped with silencing plate.
As a preferred mode, the silencing plate is noise elimination cotton.

Embodiment
The utility model will be further described below with reference to the accompanying drawings.The embodiment of the utility model includes but unlimited
In the following example.
Embodiment 1：
Referring to Fig. 1~4, a kind of exhausting silencer structure for internal combustion engine, including be sequentially communicated suction nozzle 1, unhurried current portion
2nd, adjustment part 4, diversion division 11 and noise reduction unit 5, the unhurried current portion 2 from entrance to export bore become larger until with adjustment part 4
Bore is identical, and cooling tube 3 is interspersed with the adjustment part 4, the coolant for being connected with and constantly flowing, institute are connected in the cooling tube 3
The recoil groove 8 for being equipped with noise reduction unit 5 and being oppositely arranged with 11 end of diversion division is stated, 8 outer rim tangential direction of the recoil groove is by leading
Track after the 11 end exhaust gas discharge of stream portion, 5 side wall of noise reduction unit are equipped with exhausting-gas hole 7.
In applicant, internal combustion engine, which produces exhaust gas, has big the reason is that, exhaust gas temperature is high a, gas of larger acoustic energy
Expansion multiple is big.In the present embodiment, the exhaust gas that internal combustion engine produces enters from suction nozzle 1, passes through the gradual gentle gas in unhurried current portion 2
Stream.After exhaust gas is adjusted portion 4, quick heat exchange is carried out with cooling tube 3, its temperature quickly reduces, contraction of gas, then real
The now consumption to acoustic energy for the first time.After exhaust gas is discharged from 11 end of diversion division, move forward, then strike recoil groove 8
Inner wall consumes certain acoustic energy, then realizes second of the consumption to acoustic energy.After shock, exhaust gas continue along recoil 8 inner wall of groove to
Outer ejection, due to track of the recoil 8 outer rim tangential direction of groove after 11 end exhaust gas discharge of diversion division, recoils out
Exhaust gas will then be realized with subsequently mutually being impacted from the exhaust gas of 11 end of diversion division discharge and do not extending the premise of silencing channel
Under, the quick purpose for reducing acoustic energy.The utility model, can be quick without setting longer silencing channel to ensure the consumption of acoustic energy
The acoustic energy in exhaust gas is consumed, by the consumption to acoustic energy three times, the exhaust gas acoustic energy finally discharged is smaller, and noise elimination effect is good.
