Accompanying drawing explanation
Below the content expressed by the accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is muffler structure schematic diagram of the present invention.
Be labeled as in figure: 1, air inlet pipe, 2, escape pipe, 3, housing, 4, dividing plate, 41, opening, the 5, first chamber, the 6, second chamber.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
Automotive air-conditioning system muffler of the present invention, as shown in Figure 1, this muffler is installed in pipe for flowing of refrigerant road, comprises housing 3 and is located at air inlet pipe on housing 3 front face 1 and is located at escape pipe 2 on housing 3 rear surface, and air inlet pipe 1 and escape pipe 2 axis are not on the same line, in arranged off-centre.Utilize the flowing of its potential energy for ease of refrigerant gas, air inlet pipe 1 is located at position on the upper side in the middle part of housing 3 front face, escape pipe 2 is located at the position that on housing 3 rear surface, middle part is on the lower side.
In the present invention, in housing 3, be provided with dividing plate 4, inner chamber be separated into two the first chamber 5 and the second chambers 6 in irregular shape; Air inlet pipe 1 is communicated with the first chamber 5, and escape pipe 2 is communicated with the second chamber 6, and dividing plate 4 is provided with the opening 41 of some connection two chambers.Being imported by air inlet pipe 1 of refrigerant gas, enters the second chamber 6 through the first chamber 5 by each opening 41 on dividing plate 4, and then is flowed out by escape pipe 2.
As shown in fig. 1, dividing plate 4 is by the bending plate with three-stage structure, comprises the vertical plate of top, the level board of below and the swash plate be connected between two plates.Vertical plate, level board and swash plate are equipped with opening 41, and opening 41 number on each plate is all not identical, eliminates different frequency noise to realize may correspond to.On each plate the number of opening 41 and large I according to need abate the noise main frequency determine.
Preferably, the direction of swash plate direction towards escape pipe 2 is arranged, be conducive to gas flowing.Explain according to fluid principles, the dividing plate 4 of this structure has the effect of certain guiding airflow direction, can by cavity upper, middle and lower three parts, upper gas goes out through Upper vertical plate current turns back downwards with rear side collision with wall, lower gas is turned back through lower end level board and lower end collision with wall, and common and middle part air-flow bout flows out smoothly from escape pipe, wherein cold media gas and collision with wall, make sound wave that stronger collision reflex occur in cavity wall, reach good erasure effect.
Preferably, one deck silencing cotton can be provided with on housing 3 inwall, the gas of flowing and collision with wall, strengthen its sound deadening further.
The gas flow of automotive air-conditioning system muffler of the present invention as shown by the arrows in Figure 1, cold-producing medium enters in the first chamber 5 in housing by air inlet pipe 1, cold-producing medium is at empty intraluminal inflation, part acoustic energy is converted into potential energy, then enters the second chamber 6, by the opening of different number by the opening 41 on dividing plate 4, the effect alleviating noise can be played, extend the currency simultaneously, gas is circulated and becomes mild, realize noise reduction further.The arrangement of dividing plate 4 guides direction of flow, upper gas and rear side collision with wall are turned back downwards, lower gas and lower end collision with wall turn back, common and middle part air-flow bout flows out smoothly from escape pipe 2, wherein cold media gas and collision with wall, make sound wave that stronger reflection, interference occur in pipeline, reach good erasure effect.
Automotive air-conditioning system muffler structure of the present invention is simple, easy to install, be divided into two chambers by dividing plate 4, dividing plate 4 is for having the bending plate of three-stage structure, opening 41 all established by every section of dividing plate, and opening 41 available buffer of different number eliminates the noise of different frequency.Refrigerant gas enters the first chamber 5 by air inlet pipe, can obtain in the cavities and expand and part acoustic energy be converted into potential energy, then enter the second chamber 6 by the opening 41 on dividing plate 4, extend the currency, gas is circulated and becomes mild, play Noise Reduction further.According to fluid principles explain, the bootable gas flow of dividing plate 4, makes cold media gas and collision with wall, make sound wave with cavity wall in there is stronger collision reflex, reach good erasure effect.Structure of the present invention is simple, can well reduce automotive air-conditioning system flow of refrigerant and the noise that produces, to reduce the impact of induction noise on external noise in car, improve car load NVH performance.
Above by reference to the accompanying drawings to invention has been exemplary description; but the present invention is not limited to aforesaid way; as long as adopt method of the present invention is conceived and technical scheme is carried out the improvement of various unsubstantialities or directly apply to other occasion, all drop in protection scope of the present invention.
