Description

Multilamellar perforated microstructure noise elimination flow deflector
[technical field]
The present invention relates to aerodynamic noise control field, especially a kind of multilamellar perforated microstructure noise elimination flow deflector.
[background technology]
In prior art, anechoic sheet has application in ventilating system more, has good noise elimination effect for pneumatic noise, and passes The anechoic sheet of system many by perforated metal panel as facing material, the sound-absorbing material such as internal filled glass fiber.Although traditional approach The effect reducing pneumatic noise can be played, but it exists risk and the shortcoming of sound-absorbing material effusion that sound-absorbing material lost efficacy.
Therefore, for avoiding above-mentioned technical problem, necessary offer one has structure improved noise elimination flow deflector, with gram Take described defect of the prior art.
[summary of the invention]
In order to overcome above-mentioned weak point present in prior art, it is an object of the invention to provide a kind of multilamellar micropunch knot Structure noise elimination flow deflector, its soundproof effect is good, and there is not risk and the shortcoming of sound-absorbing material effusion that sound-absorbing material lost efficacy.
In order to reach above-mentioned purpose, the present invention uses following concrete technical scheme: multilamellar perforated microstructure noise elimination water conservancy diversion Sheet, is formed an envelope by metal micropunch left plate, metal micropunch right panel, skeleton shrouding, semicircle flow guiding head and pointed flow guiding head Enclosed cavity, is provided with plate in a metal micropunch in cavity, is formed in metal micropunch left plate and metal micropunch between plate Left cavity, forms right cavity between plate in metal micropunch right panel and metal micropunch, be provided with plural pieces and put down in described left cavity The left skeleton of row arrangement, is provided with the right skeleton that plural pieces is arranged in parallel, the left skeleton of described plural pieces and plural number in described right cavity The middle part of the right skeleton of sheet is all connected by gripper shoe.
Further, left skeleton of the present invention and right skeleton are staggered each along the length direction of skeleton shrouding.
Further, left skeleton of the present invention is isometric with the length of right skeleton, and the width of right skeleton is more than left skeleton Width.
Further, left skeleton of the present invention is equipped with right-angle side kink with the both sides of right skeleton.
Further, the cross section of pointed flow guiding head of the present invention is triangle.
Further, the cross section of semicircle flow guiding head of the present invention is arc.
Present invention advantage compared with prior art is: the present invention carries out sqouynd absorption lowering noise by three layers of microperforated panel, three layers Chamber, the left and right spacing that microperforated panel is formed, it is to avoid coincidence effect occurs.This noise elimination flow deflector is not filled with any sound-absorbing material, The fiber leakage problem of sound-absorbing material and can be avoided, it is possible to be applicable to the high place of purity requirements and other special want The place asked, such as the noise elimination noise reduction in the places such as superhigh temperature, ultralow temperature, high wind pressure and wind speed.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the sectional view of the present invention;
The present invention is described in further detail below in conjunction with the accompanying drawings.
[detailed description of the invention]
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, the tool to the present invention below in conjunction with the accompanying drawings Body embodiment is described in detail.
Elaborate detail in the following description so that fully understanding the present invention.But the present invention can with multiple not Being same as alternate manner described here to implement, those skilled in the art can do class in the case of intension of the present invention Like promoting.Therefore the present invention is not limited by following public being embodied as.
Referring to shown in Figure of description 1 and Fig. 2, the present invention is multilamellar perforated microstructure noise elimination flow deflector, micro-by metal Perforation left plate 1, metal micropunch right panel 2, skeleton shrouding 3, semicircle flow guiding head 4 and pointed flow guiding head 5 form a closed cavity Body.
Wherein, in cavity, be provided with plate 6 in a metal micropunch, metal micropunch left plate 1 and plate 6 in metal micropunch it Between form left cavity 7, metal micropunch right panel 2 and metal micropunch are formed between plate 6 right cavity 8, set in described left cavity 6 Have the left skeleton 9 that plural pieces is arranged in parallel, in described right cavity 8, be provided with the right skeleton 10 that plural pieces is arranged in parallel, left skeleton 9 with The length of right skeleton 10 is isometric, and the width of right skeleton 10 is more than the width of left skeleton 9, and left skeleton 9 is equal with the both sides of right skeleton 10 Being provided with right-angle side kink 11, the middle part of the left skeleton of plural pieces 9 and the right skeleton of plural pieces 10 is all connected by gripper shoe 12, described Left skeleton 9 and right skeleton 10 are staggered each along the length direction of skeleton shrouding 3, are entered transmitting noise by chamber, twice left and right Row Noise Reduction.
It should be noted that the cross section of pointed flow guiding head of the present invention is triangle.
Also, it should be noted the cross section of semicircle flow guiding head of the present invention is arc.
But, above-mentioned detailed description of the invention is exemplary, is to preferably enable those skilled in the art Understand this patent, it is impossible to be not understood as this patent is included the restriction of scope;As long as the institute according to spirit disclosed in this patent Any equivalent change made or modification, each fall within the scope that this patent includes.
