Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
The structure of the blast pipe 1 of compressor according to embodiments of the present invention is described below with reference to Fig. 1-Fig. 4, wherein, exhaust
Pipe 1 is suitable to be connected with the exhaust outlet of compressor, that is to say, that compressor is after refrigerant is compressed, the gaseous coolant of high pressure-temperature
Miscellaneous part is oriented to by blast pipe 1.
For example, the particular location of blast pipe 1 can not be restricted, for example, blast pipe 1 can be connected to compressor and cold
Either segment refrigerant pipeline between condenser, in some embodiments, blast pipe 1 refers only to what is connected between compressor and four-way valve
Refrigerant pipeline.
The blast pipe 1 of compressor according to embodiments of the present invention, as depicted in figs. 1 and 2, the section tubular wall of blast pipe 1 to
It is recessed to form the necking part 10 of tube section reduction.
In the description of the invention, it is to be understood that term " length ", " width ", " thickness ", " interior ", " outer " etc. refer to
The orientation or position relationship shown is based on orientation shown in the drawings or position relationship, is for only for ease of the description present invention and simplifies
Description, rather than the device or element of instruction or hint meaning must have specific orientation, with specific azimuth configuration and behaviour
Make, therefore be not considered as limiting the invention.
In embodiments of the present invention, what the blast pipe 1 of compressor was generally selected is metal tube, blast pipe in some embodiments
1 is copper pipe.The processing mode of setting necking part 10 has a variety of on blast pipe 1, for example, can be stamped and formed out contracting on blast pipe 1
Neck 10, in another example, multistage pipe can be selected when making blast pipe 1, wherein the tube section area of one section of pipe is less than other pipes
Tube section area, multistage pipe are welded to connect successively, and in the homogeneous tube so connected, the less pipeline section of tube section area forms blast pipe
Necking part 10 on 1.Certainly, in the embodiment of the present invention, necking part 10 can also be made up of other processing modes, not make here
Limitation.
It should be noted that the present invention is on the basis of exhaust pipe structure disclosed in prior art, pass through the form of necking
The processing of contracting internal diameter is carried out to correct position.Inside there is into the piping arrangement of necking in the piping system of refrigerant circulation, can be effective
Compressor pressure pulsation is reduced, reduces the noise as caused by pulsation.
Specifically, for the pipeline to resonate, necking processing is carried out at maximal rate in stationary field, for abatement
Gas is maximally efficient.By emulation it is known that compared with the pipeline of the blast pipe with not carrying out necking, with necking part 10
Blast pipe 1, the unevenness of its internal flow can decline, simultaneously because the tube section area of necking part 10 is less than normal tube section
Area, impedance unbalance, the reflection to sound wave is produced, reduce pipeline noise.
So that the tube section of necking part 10 is circle as an example, formula is referred to：
In formula, d be necking part 10 internal diameter, D be blast pipe internal diameter, v0For the air velocity in blast pipe 1, C is row
The velocity of sound of refrigerant in tracheae 1.
Obviously, by controlling the position of necking part 10 and the internal diameter of necking part 10, it can be controlled in different ripple frequencies
The blast pipe 1 of lower band necking part 10, it suppresses pressure fluctuation effect and noise reduction.
In the embodiment having, by reasonable arrange parameter, after blast pipe 1 sets necking part 10, the pressure of blast pipe 1 can be made
Power pulsation rate reduces by 15% or so, and pressure fluctuation attenuation ratio reaches more than 50%, and the necking part 10 of different parameters can be to different frequencies
The pressure fluctuation of section has preferable inhibition.It is this only to pass through necking for the blast pipe of tradition addition silencer
The blast pipe 1 that processes of mode, small volume, cost are low, soundproof effect is more preferable.
Blast pipe 1 according to embodiments of the present invention, by setting necking part 10, small volume, cost are low, soundproof effect more
It is good.Pulsed by reducing pipeline, complete machine noise can be reduced.
In certain embodiments, as shown in Fig. 2 necking part 10 includes：Converging transition 11 and divergent segment 12, in refrigerant flowing side
Upward converging transition 11 is located at the upstream of divergent segment 12, and the tube section area of converging transition 11 is gradually reduced, the tube section of divergent segment 12
Area gradually increases.Using this tapered method, refrigerant can be reduced as far as possible and larger disorder is produced by necking part 10, reduced
Air current flow resistance.
Specifically, as shown in Fig. 2 necking part 10 also includes：Straight length 13, straight length 13 are located at converging transition 11 and divergent segment
Between 12.Refrigerant, in the smooth transition phase, sets the straight length 13 of suitable length, can hindered as far as possible when flowing through straight length 13
Block the pressure pulse of propagation.
Alternatively, as shown in figure 3, the tube section of necking part 10 is formed as circular.This circular shape of necking part 10 rule
Then, the necking part 10 influences easily to calculate, emulated on the noise reduction of pressure pulse, can easily calculate influenceed pulsation frequency
The frequency range of rate.Certainly, in the embodiment of the present invention, the tube section shape of necking part 10 can also be not limited to circle, such as showing in Fig. 4
In example, the tube section of necking part 10 is formed as the flat degree of lip-rounding, and the necking part 10 of such shape can also get up under suitable parameter design
Good Noise Reduction.
In the embodiment having, necking part 10 is formed as bellows (not shown), and the ripple acted on pipeline rises and falls, can
To the continuous obstruction of noise, on the premise of reasonable arrange parameter, the bellows of necking down also can be until good Noise Reduction.
In certain embodiments, on the length direction of blast pipe 1, blast pipe 1 is provided with multiple necking parts spaced apart
10.Multiple Noise Reduction can be so formed to the refrigerant of flowing, improves noise reduction.
In the pipeline diverse location of blast pipe 1, multiple identical or different necking parts 10 are added, can reach the effect of needs
Fruit, for example, identical necking part 10 can be to the noise of a certain frequency range noise reduction to greatest extent, and different necking parts 10 can be to not
With the noise noise reduction of frequency range.
Specifically, when setting multiple necking parts 10, the tube section of at least two necking parts 10 can be sized to not
Together, the tube section of at least two necking parts 10 can also be shaped to difference, or the pipe range of at least two necking parts 10
It is arranged to difference, set-up mode has a variety of, can be selected according to actual conditions.
Blast pipe 1 according to embodiments of the present invention, the noise of compressor air-discharging can be effectively reduced, and take small volume, knot
Structure is simple, handling ease, cost are low.
Air conditioner according to embodiments of the present invention, include the blast pipe 1 of compressor according to the above embodiment of the present invention, arrange
The structure of tracheae 1 is illustrated by above-described embodiment, is repeated no more here.
Air conditioner according to embodiments of the present invention, by setting above-mentioned blast pipe 1, especially apply in outdoor machine of air-conditioner, can
Pipeline pulsation is reduced, reduces outer machine noise.
In addition, other compositions of air conditioner according to embodiments of the present invention, such as condenser and compressor etc. and operation
