Fig. 5 is the assembling schematic diagram of the of the present utility model first built-in muffler A and the second built-in muffler B, flexible pipe 8 one
End riveted can be filled in flexible pipe built-in muffler 6 after aluminum hull 7 is interior, make the aluminum hull position of its close noise source side, due to
Particularity in its structure, muffler can be subject to the tooth form constraint of aluminum pipe in flexible pipe and aluminum hull in flexible pipe, will not be because of movement
And influence erasure effect.For simplicity, the schematic diagram that built-in muffler is installed in flexible pipe one end is only depicted in Figure 5, this
Field it will be appreciated by the skilled person that eliminating the structure that the flexible pipe other end installs built-in muffler in figure.
Service intermittent mode according to air conditioning for automobiles, the mechanical impact sound of inlet valve, air bleeding valve caused by it is gentle
Noise waves, by Fourier principle, can be converted into sine wave by the characteristics of noise of stream shows multifrequency in air intake duct, according to
Sine waveform feature, it is known that：The sound wave of different frequency can be presented different crests, trough, Ran Houtong in synchronization
Cross vector superposed, it is possible to decrease amplitude, i.e., the energy of noise waves can obtain a certain degree of reduction, meanwhile, the vibration of pipeline also can
There is different degrees of reduction, can thus play a part of to reduce and eliminate compressor noise.
Seen according to experiment, to high, medium and low band limits, i.e. the noise of multifrequency segment limit more has the first built-in muffler A
Effect, the second built-in muffler B centerings, low-frequency range noise it is more effective, so under actual condition, being surveyed using noise measuring equipment
The apparent position of actual noise frequency range and noise source is tried out, it is from the combination of corresponding muffler, such as built-in using first
Muffler A or the second built-in muffler B, is installed in being close to sebific duct one end of noise source position；There is one kind side in addition
Formula, is the first built-in built-in muffler A of muffler A+ first, or the second built-in built-in muffler B of muffler B+ second, and
Or first the built-in built-in muffler B of muffler A+ second mode, this mode be by muffler assembling the two of sebific duct
End, is which end for being located at sebific duct as the first built-in muffler A and the second built-in muffler B, be according to specific noise source
Which band limits and judge apart from the position at sebific duct two ends, the effective frequency of the band limits of noise source close to muffler
Segment limit, the muffler is just used near that end of noise source, and the other end is similarly.
The application of built-in muffler combination, cooperates by with main engine plants on more than, on different product, disappears for difference
Sound device is combined, and the noise before and after being combined using built-in muffler for air-conditioning duct has done multiple test, as a result shows：Using interior
After putting muffler combination, the noise of the special frequency channel to eliminating and reducing automotive air-conditioning system is very effective, if it can be promoted
Use, have very important meaning for vehicle energy saving, environmental protection.
Above content is to combine the further description that specific preferred embodiment is made to the utility model patent,
It cannot be assumed that the specific implementation of the utility model patent is confined to above-mentioned these explanations.For the utility model art
Those of ordinary skill for, on the premise of the utility model inventional idea is not departed from, some simple deductions can also be made
Or replace, should all be considered as belonging to protection domain of the present utility model.
