It is equipped with airflow channel between chamber C, exhaust noise silencing chamber B and exhaust noise silencing chamber C, is equipped between exhaust noise silencing chamber A and exhaust noise silencing chamber B
Connecting tube, the exhaust coil pipe are connect with exhaust noise silencing chamber C.
Airflow channel between exhaust noise silencing chamber B and exhaust noise silencing chamber C described in the utility model is from exhaust noise silencing chamber B to row
The aperture in the direction gas silencing cavity C is gradually reduced.
Exhaust noise silencing chamber A described in the utility model, it resonator, exhaust noise silencing chamber B, is respectively arranged at the top of exhaust noise silencing chamber C and disappears
Sound lid, the connecting tube both ends are protruded into intracavitary across the noise reduction lid of exhaust noise silencing chamber A and exhaust noise silencing chamber B.
Cylinder head component described in the utility model includes cylinder head, air suction silencer, and cylinder head is mounted on the cylinder head of cylinder block
Position forms discharge chamber between cylinder block and cylinder head.
Utility model works principle is as follows: refrigerant enters in cylinder after being inhaled into from air suction silencer, after compressing
It is discharged into discharge chamber from cylinder again, exhaust noise silencing chamber A is initially entered by runner and resonator level-one expands noise reduction, due to altogether
Tymapanum and the A intercommunication of exhaust noise silencing chamber, cavity volume increasing are twice above, and level-one expansion erasure effect greatly promotes, and then passes through again
It crosses connecting tube and enters the expansion noise reduction of exhaust noise silencing chamber B second level, enter the expansion noise reduction of exhaust noise silencing chamber C three-level by airflow channel,
Finally by entering refrigeration system circulation outside exhaust coil pipe discharge body.
The utility model has the advantage that 1, air-flow road through the multistage noise-reducing structure of upper setting, noise reduction compared with prior art
Effect is more preferable；2, cylinder block two sides are arranged symmetrically exhaust noise silencing chamber, and balance is more preferable, reduce the noise of crank rotation generation；
3, setting resonator is connected to exhaust noise silencing chamber A, and cavity volume increases, and further increases erasure effect；4, exhaust noise silencing chamber B with
Airflow channel sectional area between exhaust noise silencing chamber C is gradually reduced, and the exhaust gas pulses of compressor is improved, when running compressor
Gas generate lower noise.
