Provided with exterior enclosure wall 3 and interior enclosure wall, the interior enclosure wall is located outside positioned at interior, exterior enclosure wall 3, and exterior enclosure wall 3 is convex
For the arc of construction wall outer surface, the both sides of exterior enclosure wall 3 are respectively equipped with left vent and right side vent, inside go along with sb. to guard him
Wall is provided with a room ventilation mouth, and forming one between exterior enclosure wall 3 and interior enclosure wall connects left vent, right side exhaust
Mouthful and room ventilation mouth ventilating duct, be provided with outer layer perforated plate 11 close to the side of exterior enclosure wall 3 in ventilating duct, close interior enclosure wall
Side is provided with internal layer perforated plate 12, and internal layer sound-absorbing material 10 is provided between internal layer perforated plate 12 and interior enclosure wall, exterior enclosure wall 3
Medial surface is provided with outer layer sound-absorbing material 8.
In the present embodiment, exterior enclosure wall 3 and interior enclosure wall use multilayer gluing wood material, have while proof strength
There are certain insulation and sound insulation property.Outer layer perforated plate 11 and internal layer perforated plate 12 are aluminium sheet material, and processing is more on aluminium sheet
Individual circular hole, there is preferable resonance sound-absorbing performance.Outer layer sound-absorbing material 8 and internal layer sound-absorbing material 10 are rock wool porous sound absorption material
Material, has certain heat-insulating property, while be fire proofing material.Packed density is less between internal layer perforated plate 12 and interior enclosure wall
Rock wool sound-absorbing porous material, make that there is larger porosity in cavity.Shutter 6 is band blinds, using aluminium sheet material, lightweight
It is high-strength, there is preferable inoxidizability and dicoration, can play a part of keeping the sun off, rainwater, inside configuration can be slowed down
The weathering oxidizing process of material, ensure that the long period uses, reduce cost.The aperture of steel wire 7 is less than 1cm, prevents birds and beasts from building
Nest is got in, additionally it is possible to is prevented some float things from being got in such as leaf, polybag with air-flow, is ensured indoor
Cleaning.
The lower section of window 2 is provided with upper windowsill 18, outdoor corresponding to flooring to be provided with lower windowsill 16, exterior enclosure wall 3 and interior
The upper and lower ends of enclosure wall are separately fixed on windowsill 18 and lower windowsill 16, the vertical plane of interior enclosure wall and interior architecture wall
Concordantly, interior enclosure wall is divided into left side enclosure wall 5 in enclosure wall 4 and right side by the room ventilation mouth on interior enclosure wall, simultaneously
Also outer layer perforated plate 11 and internal layer perforated plate 12 are divided into left and right two parts.Outer layer perforated plate 11 and internal layer perforated plate 12 are distinguished
It is fixed on by fix bar 9 between exterior enclosure wall 3 and interior enclosure wall, fix bar 9 is perforated with outer layer perforated plate 11 and internal layer respectively
Plate 12 is arranged vertically, and the both ends of fix bar 9 are separately fixed on exterior enclosure wall 3 and interior enclosure wall.Enclosure wall 4 and right side in left side
The sliding window sash 13 for setting wooden plywood to make between interior enclosure wall 5, by being fixed on upper windowsill 18 and lower windowsill 16
On the push-and-pull of slide rail 14 or so.Sealing joint strip 15 is set in the gap in sliding window sash 13 and right side between enclosure wall 5.Sliding window
Fan 13 moves left and right the openings of sizes that can realize room ventilation mouth, adapts to wind speed outside different chamber, need not divulge information when, can
To be turned off.The internal layer perforated plate of room ventilation mouth both sides is with enclosure wall 5 in enclosure wall in left side 4 and right side the same as wide a, left side
To fill internal layer rock wool between the internal layer perforated plate of room ventilation mouth both sides respectively more for enclosure wall 5 in enclosure wall 4 and right side in side
Hole sound absorbing material.Shutter 6 and steel wire 7, steel wire 7 are equipped with the left vent and right side vent of exterior enclosure wall 3
The inner side of shutter 6 is invested, is fixed on construction wall and exterior enclosure wall 3.
Draught principle：The air-flow of different directions can enter inside configuration by the ventilating opening of the both sides of exterior enclosure wall 3.Work as room
When the dynamic direction of outer air flow is vertical or angled with external wall, the left side that air-flow directly passes through on exterior enclosure wall 3 is divulged information
Mouth and right side vent enter inside configuration；When outdoor air flows are parallel with external wall, air-flow is through arcuate peripheral revetment 3
Surface, air velocity can be more than the air velocity apart from the surface certain distance position of exterior enclosure wall 3, according to bernoulli principle, outside
The surface pressure of enclosure wall 3 is less than the air pressure apart from its certain distance position, forms pressure difference, and air-flow is pressed into left vent and the right side
Side ventilating opening.
After air-flow is by left vent and right side vent, inside configuration is entered with certain speed.Ventilating duct is outer
The outer layer sound-absorbing material 8 of the side of enclosure wall 3 has a larger flow resistance, and its superficial air velocity is relatively small.On the contrary, enclosed in ventilating duct
The surface flow resistance of internal layer perforated plate 12 of revetment side is smaller, and air velocity is very fast, also according to bernoulli principle, divulges information indoors
Mouth position forms pressure difference, is more than interior enclosure wall side atmospheric pressure close to the side atmospheric pressure of exterior enclosure wall 3, air-flow is pressed towards room
It is interior.Meanwhile two-way blast converges at vent position indoors at left and right sides of room ventilation mouth, the arc knot of exterior enclosure wall 3 in addition
Convergence effect on the inside of structure, is formed compared with air blast, air-flow is got in enough speed.
Principle of noise reduction：After air-flow, which carries sound wave, enters inside configuration, acoustic energy causes the hole in rock wool sound-absorbing porous material
Gap shakes with fiber, acoustic energy is converted into heat energy, consumes a part of high-frequency sound energy.Outer layer perforated plate 11 and the phase of internal layer perforated plate 12
There is larger hole for rock wool sound-absorbing porous material, sound wave causes its hole ambient gas to shake, can consume certain intermediate frequency
Several energy.Larger cavity in internal layer perforated plate 12 and left side in enclosure wall 4 and right side between enclosure wall 5, under sound wave effect
The acoustic energy of vibrations consumption all-bottom sound.Whole process terminates, and when air is got in, its each frequency range sound wave has certain consumption,
It can reach obvious noise reduction.
