The muffler body is made of galvanized steel sheets.
By the technical scheme provided by the utility model, the utility model discloses an idle call tuber pipe silencer, its silencer body are "S" shape, make the air current get into behind the silencer through twice buckling, have increased the reflection number of times of sound wave in the silencer, have increased the contact chance of acoustic absorber and sound wave promptly, make the noise absorption absorb more completely. The utility model discloses an inside two-layer orifice plate that is equipped with of silencer, orifice plate itself are noise-abatement structure, and the design of two-layer orifice plate makes the noise cancelling effect of orifice plate obtain strengthening, and the hole site of two-layer orifice plate is crisscross to be laid each other, makes the air current through the aperture can disperse to the direction of difference to make the noise weaken. The air outlet and the air inlet of the silencer body are provided with the partition plates, so that the air flow entering and flowing out can be dispersed by the partition plates, and the noise of the air flow is weakened. The silencer body and the flange are integrally formed, so that the structure of the silencer can be more stable, the flange is tightly connected with the silencer body, and the noise caused by air leakage can be prevented from being dispersed outwards.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic structural diagram of an air duct opening according to an embodiment of the present invention.
In the figure: 1. the silencer comprises a flange, a silencer body, a sound absorption lining, a first orifice plate, a second orifice plate and a partition plate, wherein the sound absorption lining is arranged at 3, the first orifice plate is arranged at 4, the second orifice plate is arranged at 5, and the partition plate is arranged at 6.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 and 2, the air duct silencer for air conditioner provided by this embodiment includes a silencing structure, and a flange 1 and a silencer body 2 that are integrally formed, where the silencing structure includes a sound absorbing liner 3, a first orifice plate 4, a second orifice plate 5, and a partition plate 6. The silencer body is "S" shape, and flange 1 is fixed in the both ends of silencer body air outlet and income wind gap respectively, and the business turn over wind gap department of silencer body 2 still welds cross baffle 6, will advance, the air outlet falls into four little wind gaps. After the air current gets into muffler body 2, through the twice refraction of "S" shape corner, when making the air current obtain the buffering, also increased the absorption of acoustic liner 3 to the noise, and baffle 6 divides into four little wind gaps with the wind gap, played the effect of weakening to the flow and the velocity of flow of air current to weaken the noise of air current.
The inner wall of the silencer body 2 is provided with a sound absorption lining 3 made of fireproof silencing cotton or glass fiber yarns.
The inboard of sound absorption lining 3 is equipped with first orifice plate 4 and second orifice plate 5 in proper order, the hole site of first orifice plate 4 and second orifice plate 5 is crisscross the laying each other, the perforation rate of first orifice plate 4 and second orifice plate 5 is 30% ~ 40%, the hole of first orifice plate 4 and second orifice plate 5 is the bell mouth, the drill way diameter that is close to 2 inner wall one sides of muffler body is greater than the drill way diameter of keeping away from 2 inner wall one sides of muffler body on every orifice plate, the scope of first orifice plate tip drill way diameter is 1 ~ 6mm, the scope of second orifice plate tip drill way diameter is 0.7 ~ 5 mm. Because the hole on the orifice plate is the bell mouth, can make the air current through the orifice plate produce and disperse, weaken the velocity of flow of air current, the air current is once weakened the back, and then the aperture that the diameter is littleer, and the air current is through twice buffering, not equidirectional dispersing, can make the velocity of flow of air current obtain further weakening to reduce the noise of air current.
The cross section of the silencer body 2 is rectangular or circular, and when the cross section is rectangular, all corner transition parts are smooth transition. Smooth transition can reduce the friction loss of air current, also can reduce the impact of air current to the muffler body, when reducing the noise, also prolonged the life of silencer, make equipment more durable.
The utility model discloses an idle call tuber pipe silencer, its simple structure through the combined action of a plurality of noise elimination parts, makes the noise of air conditioner tuber pipe weaken by a wide margin, and noise reduction effect is obvious, and its stable in structure also makes equipment more durable.
