Preferably, the shunting jag part use arc transition, the radius of circular arc be tube body height 13.
Preferably, angle is 120 ° between the side wall of the shunting peak both sides, the side wall and air outlet of the shunting peak both sides
The angle of the tube wall at place is 150 °.
Further, the noise reduction louver ends, the side of close air outlet are also associated with the deflector being horizontally mounted, institute
State and be laid with rubber layer on the inside of deflector.
Preferably, the deflector and noise reduction screen both sides are laid with rubber layer.
Air passage airflow device provided by the utility model is compact-sized, using modularized design, takes small, its shunting
It is all very excellent with erasure effect, compared with prior art, without installing silencing means and part flow arrangement respectively again, it enormously simplify
Installation steps, in small space, its advantage easy for installation becomes apparent, and also reduces difficulty of construction, in addition, for business
For air-conditioning system, clean difficulty and be also greatly lowered, there is good promotional value.

Embodiment
In the description of the utility model, it is to be understood that the orientation or position relationship of the instruction such as term " interior ", " outer "
Based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model and simplifying description, without referring to
Show or imply that the device of meaning or element there must be specific orientation, with specific azimuth configuration and operation, therefore cannot manage
Solve as the limitation to the utility model.
In addition, term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be mechanically connecting or being electrically connected
Connect or the connection inside two elements, can be directly connected, can also be indirectly connected by intermediary, for
For those of ordinary skill in the art, the concrete meaning of the term can be understood as the case may be.
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.
Fig. 1-3 shows a kind of air passage current divider for having shunting and silencing function concurrently, which uses modularization
Design, including hollow square tube body 1, the middle part of tube body 1 offer an air inlet, and 1 both ends of tube body are air outlet,
1 inner wall of tube body, the position of face air inlet are recessed inwardly to form shunting peak 2, in the tube body 1, between shunting 2 both sides of peak etc.
It is laminated away from ground and multi-disc noise reduction screen 3 is installed, the side wall at the noise reduction screen 3 and shunting peak 2 is parallel to each other and the noise reduction grid
The inner side of plate 3 is uniformly laid with rubber layer 4 made of soft rubber.
It is well known that muffler is broadly divided into resistive muffler, resistant noise-reducing device and impedance complex muffler, its principle
Main is exactly to be absorbed by sound-absorbing material sound, therefore in general, can all use surface be laid with rubber layer 4 every
Plate, some partition plate composition noise reduction layers being obliquely installed, on the one hand ensures on the other hand air-flow can be by realizing sound by partition plate
Reflection absorbs, but this design necessarily brings greater pressure to lose, and air outlet is often only towards a direction,
Also need to set flow-guiding structure to be shunted again again.And the current divider of above-mentioned technological means is used, by current divider
It is interior that shunting peak 2 is set, then the noise reduction screen 3 for having refluence and silencing function concurrently is set in shunting 2 both sides of peak, both save material
Expect, by saving space.
Preferably, the rubber and plastic layer surface is equipped with continuous undulating pleats.
If shunting it is unreasonable, it is easy to cause shunting noise, therefore, inventor when design noise reduction screen 3, intentionally
Edge 3a of the multi-disc noise reduction screen 3 close to air inlet side is staggered identical spacing in the horizontal direction, thus both can ensure that and appoint
Anticipate the air passage that is formed between adjacent two blocks of noise reduction screens 3 can effective inlet air, rubber layer 4 on the one hand can be made full use of to absorb
Noise, on the other hand can then avoid air quantity from concentrating on generation noise in a certain narrow and small air passage, lose wind pressure.
Preferably, the shunting peak 2 top use arc transition, the radius of circular arc be tube body height 13, by repeatedly
Experiment and test, inventor has found that 2 top of shunting peak is arranged to arc-shaped can further reduce wind-dryness, while reduces wind pressure
Loss, and the radius of circular arc then approximately be equal to 13 tube body, 1 height.
Preferably, angle is 120 ° between the side wall of shunting 2 both sides of peak, the side wall of shunting 2 both sides of peak and outlet air
The angle of tube wall at mouthful is 150 °.
Further, 3 end of noise reduction screen, the side of close air outlet are also associated with the deflector 5 being horizontally mounted,
The inner side of deflector 5 is laid with rubber layer 4.
Further, 3 both sides of deflector 5 and noise reduction screen are laid with rubber layer 4.
Above-described embodiment is the preferable implementation of the utility model, and in addition, the utility model can be with other sides
Formula is realized, any on the premise of the technical program design is not departed from obviously to replace in the protection model of the utility model
Within enclosing.
In order to allow those of ordinary skill in the art more easily understand the utility model relative to the prior art improvement it
Place, some attached drawings of the utility model and description have been simplified, and for the sake of clarity, present specification is omitted one
A little other elements, those of ordinary skill in the art should be aware that these elements omitted also may make up the interior of the utility model
Hold.
