Abstract
The bundling thin tube silencer uses thin flexible tube to form bundling, and its end portion is poured in the pouring head by using plastic cement. Both ends are ventilated. As air passes therethrough, the noise in the air supply and the piping is substantially reduced. The silencer can be used for noise reduction and silencing of a fresh air machine and an indoor air purifier, and has the characteristics of small volume, good silencing effect, low wind resistance, simple structure and low manufacturing cost.
Description
Technical field
Bundle pipes muffler, a kind of muffler made of boundling tubule, for dispelling source of the gas and pipe when conveying air
Noise in road.
Technical background
When needing to indoor particularly bedroom conveying air, the technical issues of noise reduction is exactly one extremely important.Especially
It is to during indoor air-supply with thinner pipeline, the outlet of pipeline can pass out apparent exceeded noise, moreover, it is particularly indoors
The muffler used in bedroom, moulding, volume, the energy consumption of volume and frequency range, muffler to its noise have harsh requirement.
Although there are many kinds of the technical solutions that can be selected, currently existing scheme is all unsatisfactory.
The content of the invention
It is an object of the present invention to propose a kind of small windage, excellent noise reduction effect, it is small, be adapted to various outer hull shapes
It is shape, easy to install, the organization plan of cheap Novel muffler.
It is a feature of the present invention that boundling tubule muffler；By boundling noise reduction snorkel 1 and pour first 2 and form, noise reduction
Snorkel 1 is the pipe that diameter 0.5---10 mm lengths are 50---1500 millimeters, and a bundle of noise reduction snorkel 1 forms noise reduction and lead to
Tracheae boundling 3, all noise reduction snorkels 1 in noise reduction snorkel boundling 3 are the snorkel of both ends open, noise reduction snorkel collection
All its ends of noise reduction snorkel 1 in beam 3, which are cast in, to be poured in first 2.
Further, all noise reduction snorkels 1 in the noise reduction snorkel boundling 3, two end is poured respectively
It different is poured at two in first 2.
Description of the drawings
Fig. 1 is a kind of schematic diagram of example of the present invention.Show that noise reduction snorkel to be only cast in there are one holding in figure
Rectangle pours the scene in first 2；In figure, 1 is noise reduction snorkel；2 be to pour head, and 3 be noise reduction snorkel boundling.
Fig. 2 is the end view of Fig. 1.
Specific implementation
Boundling tubule muffler belongs to a kind of resistive cellular muffler of extramalization, and performance can pass through cellular noise reduction
The formula of device calculates.The principle of resistive muffler is that acoustic energy is converted into thermal energy using the frictional force and viscous force of pipe surface,
So as to achieve the purpose that noise elimination.Traditional honeycomb muffler is mostly used the occasion in low speed Wind Volume, and the pipeline of use is all metal
Deng more hard material." tubule " as " honeycomb " is usually all 50 millimeters or more of hard tube, because too thin pipe, then
Inside installation sound-absorbing material is just had any problem.Honeycomb duct can not be too many, and otherwise, structure is just too complicated, overall cost-effective performance
It is too low.
The innovative point of the present invention is that by cellular muffler extramalization usual cellular muffler at most only has tens
Tubule, can will be bundled together into hundred up to ten thousand tubule collection here its extramalization.The tubule of usual cellular muffler,
A diameter of 50 millimeters or more of hard tube or square tube, here using 0.5----10 millimeters of small hose, representative value is 1-3 millimeters；
The hard tube of usual cellular muffler is arranged in parallel, and long hose is employed herein.
Since tube inner diameter is far smaller than wave length of sound, and the arrangement at random of outlet air port or even chaotic accumulation, inner-walls of duct
Specific surface area significantly increase, frictional force is huge, and acoustic impedance is huge, be achieved in the spatial volume of a very little very well
Erasure effect.
The windage of boundling tubule muffler depend on canaliculate end area summation and tubule length, it is easy to count
It calculates.
Boundling tubule muffler is simple to manufacture, and it is extensive to be used as the material source of noise reduction ventilation duct 1, cheap；
Casting craft is similar to pouring for hollow fiber film assembly, and colleague is readily appreciated that and grasps.
In use, the free end for pouring first 2 end or noise reduction snorkel boundling 3 can serve as inlet end or outlet side
Mouthful.
Hose is selected, the moulded limitation from material of muffler can be made, can roll up and be deposited in a smaller
Space in, reduce the volume of complete machine.
The both ends of noise reduction snorkel boundling 3 can be poured respectively two it is different pour in head, both ends is made all to fix
Come, be suitable for some specific occasions.
Circular, rectangle and other any shapes can be had by pouring first 2, be adapted to different applications.
Claims (2)
1. boundling tubule muffler, it is characterised in that：By boundling noise reduction snorkel 1 and pour first 2 and form, noise reduction snorkel 1
The pipe for being 50---1500 millimeters for diameter 0.5---10 mm lengths, a bundle of noise reduction snorkel 1 form noise reduction snorkel boundling
3, all noise reduction snorkels 1 in noise reduction snorkel boundling 3 are the snorkel of both ends open, in noise reduction snorkel boundling 3
All its ends of noise reduction snorkel 1, which are cast in, to be poured in first 2.
2. boundling tubule muffler according to claim 1, it is characterised in that：Institute in the noise reduction snorkel boundling 3
There is noise reduction snorkel 1, two end is cast in two and different pours in first 2 respectively.
