There is a phenomenon where reflections, interference at the interface of anti-mutation, to realize noise reduction.In a specific embodiment, a plurality of noise reductions
The mode of the interval of baffle 521 interaction arrangement an are as follows: silencing baffles 521 are mounted on the bottom centre position of silencing cavity 511, then separately
One silencing baffles 521, which are spaced, is mounted on the top center of silencing cavity 511, in positioned opposite up and down, disappears followed by third
Sound baffle 521 is mounted on the left end center of silencing cavity 511, and the 4th silencing baffles 521 are mounted on the right end of silencing cavity 511
Center, opposite in left and right, the 5th silencing baffles 521 are mounted on the bottom centre position of silencing cavity 511, and so on follow
Ring, wherein upper and lower position in no particular order, can be with reversed order, and left-right position also in no particular order can be up and down and left with reversed order
Between right position also in no particular order, a plurality of silencing baffles 521 are parallel to each other；And it is located at the rear of the compressor 1；It is a plurality of
The connection of 5211 air-tightness of connecting tube of the silencing baffles 521 is integral pipe 6, and the company of the entrance air-tightness of integral tube 6
It is connected to one end of the capillary 4, the outlet for being connected to the filter 3 of the other end air-tightness of the capillary 4 is described
The entrance for being connected to the filter 3 of the outlet air-tightness of condenser 2, the outlet air-tightness of the compressor 1 are connected to
The entrance of the condenser 2, the entrance for being connected to the compressor 1 of the outlet air-tightness of integral tube 6, is followed to form refrigeration
Ring, refrigerant is sucked from compressor 1 to be compressed, and is entered condenser 2 afterwards and is condensed, and is subsequently entered the filtering of filter 3, is entered back into capillary
4 expenditure and pressures cool down to silencing cavity 511 followed by entering in Flapper type evaporator 52, finally return in compressor 1.
The gas outlet of first order expanding denoising device 300 is connected to the air inlet 512.
When work, the air outlet of blower 7 is communicated to the input end of pipeline 8 to be purged, it will by reducing connecting tube 400
The outlet port of pipeline 8 to be purged is connected to the input end of first order expanding denoising device 300；It is high that blower 7 blows out high temperature
The steam of pressure high speed purges pipeline, and the steam of purged high temperature and pressure high speed is introduced into the first order expanding drop
It makes an uproar and carries out first order expanding noise reduction in device 300, then push the rotation of flabellum 11 acting again, play the second level and drop for the first time
The effect made an uproar, in specific implementation, the flabellum 11 can use turbine flabellum, and the flabellum 11 drives the compressor in turn
1 movement, the compressor 1 will become the gaseous refrigerant of high temperature and pressure after refrigerant sucking compression, and then compressor 1 is by gaseous state
Refrigerant is transported in condenser 2；Condenser 2 is by gaseous refrigerant condensation and heat release, the vapor refrigerant of high temperature and pressure become
The liquid refrigerant of cryogenic high pressure, refrigerant can enter in the filter 3 after condensation and filter out impurity, then into
Enter in the capillary 4, by the expenditure and pressure of capillary 4, the pressure of refrigerant will reduce, and enter finally into Flapper type steaming
Among the integral tube 6 for sending out device 52, the diameter of the connecting tube in Flapper type evaporator 52 than blood capillary 4 manage it is broad very much, low temperature
The liquid refrigerant of low pressure enters after Flapper type evaporator 52 evaporation that can rapidly absorb heat, and ultimately becomes the gas of isothermal and isobaric
State refrigerant, gaseous refrigerant can be sucked again by compressor and be compressed later, continue refrigeration cycle.As refrigerant is disappearing
Evaporation endothermic in Flapper type evaporator 52 in sound chamber 511, the temperature in 511 body of silencing cavity are also decreased, are finally realized
The effect of refrigeration plays second of second level noise reduction to realize the function of cooling noise reduction.On the other hand, high temperature and pressure
After the steam of high speed drives the flabellum 11 to rotate, kinetic energy is reduced, and speed and pressure reduction then proceed to blow to a plurality of noise reductions
Baffle 521 carries out physical barriers by silencing baffles 521, further decreases speed, play second level third time noise reduction,
And muffler chamber 9 is formed between adjacent silencing baffles 521, and form the sectional area mutation of internal structure, further
Weaken noise generation and propagation so that the sound wave of certain frequencies the interface that acoustic impedance be mutated occur reflect, interfere,
Realize that the decrease of noise functions of the second level the 4th time finally makes the steaming of high temperature and pressure high speed in conjunction with the cooling decrease of noise functions of refrigeration system
Stripping temperature, pressure, speed are greatly lowered.
