Description
Technical field
The utility model belongs to compressor accessory field, specifically, relates to a kind of baffler be used to preventing or suppress noise, more particularly, relates to a kind of baffler with cutting.
Background technique
Chiller plant (for example refrigerator) is household electric appliance commonly used in the daily life.Chiller plant is because itself being affected by its system, and in the process of compressor normal operation, system can produce a series of noise, mainly comprises: refrigeration agent eruption, the sound that flows, compressor operating sound, system unit (condenser, vaporizer) resonance sound.The noise that produces in order to alleviate chiller plant, prior art adopt transition tube to alleviate the noise that chiller plant produces usually, and capillary tube is inserted in the transition tube.Capillary tube is when the ejector refrigeration agent, and the part that capillary tube is inserted in the transition tube will produce vibration in transition tube, thereby alleviates the noise of chiller plant.So baffler has become the parts of chiller plant indispensability.
The kind of baffler is a lot, but studies carefully its noise elimination mechanism, can be divided into six kinds of main types to them again, i.e. resistive muffler, resistant noise-reducing device, impedance complex formula baffler, microperforated panel baffler, aperture baffler and active baffler.The most frequently used in the air-conditioning is the resistant noise-reducing device, that pipe and chamber by abrupt interface combines, like well an acoustic filter, similar to electrical filter, each cell with pipe is a mesh of wave filter, air quality in the pipe is equivalent to inductance and the resistance on the electricity, is called acoustical mass and acoustic resistance.Volume of air in the cell is equivalent to the electric capacity on the electricity, is called acoustic compliance.Similar with electrical filter, each cell with pipe has the natural frequency of oneself.When the sound wave that includes various frequency contents enters first short tube, only near the sound wave of some frequency first mesh natural frequency could arrive second short tube mouth by mesh, the sound wave of other frequency then can not pass through mesh, can only in cell, come back reflective, therefore, we claim that this sound wave is had the structure of filter function is acoustic filter.Choosing suitable pipe and chamber makes up. and just can filter the noise of some frequency content, thereby reach the purpose of noise elimination.The resistant noise-reducing device is applicable in the elimination, low-frequency noise.
Chinese patent application numbers 200820161298.4 in open day on November 25th, 2009, discloses the patent document that a name is called silencer for air conditioner.This model utility relates to a kind of silencer for air conditioner, it is characterized in that comprising shell, liner, described shell is circular tube shaped, liner is installed in the enclosure, described liner is the circular tube shaped that two ends connect, be provided with circular bottom part at the one end, some filter screen pieces and several flow regulator pieces are installed in liner inside, have several throttle orifices at flow regulator pieces, described filter screen piece and flow regulator pieces begin successively the interval from circular bottom part and pack into the liner, in outermost filter screen piece outside fixing device for installing, fixing device and liner secure fit; Shrink at the two ends of shell, forms outlet and entrance.This model utility combines throttling arrangement and baffler, makes it have simultaneously the advantages such as throttling, noise reduction, filtration.But do not need to filter during the work of general baffler, increase the effect that the filter screen piece does not only increase noise reduction, also increased cost.
China Patent No. 201120268686.4, open day on 05 30th, 2012, the patent document that a kind of name is called a kind of vehicle air conditioning pipeline pressure silencer is disclosed, this model utility relates to a kind of vehicle air conditioning pipeline pressure silencer, the resonant cavity that comprises elongated cylindrical, the chamber wall inward at both ends of resonant cavity closes up and forms two soldering openings, and the soldering opening internal diameter is less than the internal diameter of resonant cavity, is connected with shoulder structure by neck between soldering opening and the chamber wall.The beneficial effect of this model utility: new process is increased work efficiency by to the metal tube cold-extrusion shaping, guarantees product quality; Novel process has kept the physicochemical property of metallic material, has promoted anti-(being subjected to) pressure capability index of product ontology, and product can use maintenance-free all the year round after being shaped in non-artificial destruction (or other annexes damage) situation; It is simple in structure, adopts expanding chamber (single-cavity resonance stops up) principle, and dividing reduces pressure defeats by force, and the absorption acoustic reactance is interfered reflective sound wave, reduction and the dry sound of elimination audio frequency; Overall appearance is generous, and cost of production is low, and is easy to use and reliable.When but this structure air-flow had just entered baffler, the sidewall that air-flow is close to the intermediate resonance chamber flowed, the outside that sound can spread thereupon, and soundproof effect is undesirable.And be easy to be confused about when installing positive and negative, bring difficulty for workman's installation.
A lot of inside in above-mentioned two parts of patents also having occurred now increases patent aspect a lot of quieter materials, but there is complex structure in these bafflers, the problem that processing cost is high.And general baffler needs minute inlet end and outlet side from structure, can not setup error during installation, and easy to process for the baffler part, from outer surface, the two ends appearance of general baffler is identical, is difficult to distinguish, and some bafflers end after processing is labelled, but the label ratio is easier to lose, so that the workman is difficult to judge positive and negative end.
Summary of the invention
The problem that solves
, complex structure undesirable for existing silencing apparatus erasure effect, the problem that processing cost is high, the utility model provides a kind of baffler with cutting, and simple in structure, good muffling effect are easy to process, and the positive and negative joint of convenient identification, and the workman installs easily.
