Low, pipeline intrinsic frequency is intensive (being spaced between rank and rank smaller), is difficult to walk pipe direction by change and avoids compressor operation frequency
Rate, in addition U curved increase improves cost, also has part type since structure limits, and there is no space increase U is curved.
As shown in Figure 1, being one section of cross-section pipe bend, if the diameter of bend pipe is d, the corner of bend pipe is β, bend gas intake mouth
The pressure at place is P, then the resultant force in bend pipe angular bisector direction is
If P is definite value, F is also definite value, and quiet deformation and static stress are only caused to pipeline；As P=Pm+ Δ P, it is with joint efforts
P is pipeline mean effective pressure in formula, and Δ P is fluctuation pressure maximum amplitude, and first item is static load caused by P in formula
Load forces do not cause to vibrate；Section 2 is alternating force caused by pressure fluctuation, it is the exciting force for leading to pipe vibration, by its power
Width is denoted as Δ F,
When β=0.Then △ F=0N will not generate the vibration of pipeline even if illustrating there is pressure fluctuation in straight tube.
With the increase of β, turning exciting force increases, and illustrates turning there are stress concentration, bending is bigger, and bending part is answered
Power is bigger.

Specific embodiment
In conjunction with to shown in Fig. 5, embodiment according to the present utility model, air-conditioner outdoor unit includes compressor 1 referring to fig. 2, pressure
The exhaust outlet and/or gas returning port of contracting machine 1 are connected with air conditioner piping 2, and air conditioner piping 2 includes spring pipeline section 3.Preferably, air-conditioning is matched
Pipe 2 avoids the running frequency of compressor 1 by spring pipeline section 3.
The air conditioner piping 2 of the air-conditioner outdoor unit includes spring pipeline section 3, and the stress distribution of spring pipeline section 3 is uniform, Ke Yiyou
Effect reduces piping stress and concentrates, while bourdon tube flexibility is relatively preferable, can be vibrated with effective attenuation, reduces pipeline close to compressor
The former a flexure stresses of suction gas tube orifice problem bigger than normal disperses pipeline stress, therefore can pass through spring when compressor 1 works
Pipeline section 3 disperses the stress generated in 1 vibration processes of compressor, while can use the elastic extenuation vibration of spring pipeline section 3, makes
Operation of air conditioner frequency can be avoided using better simply structure by obtaining air conditioner piping 2, so that the increase for overcoming U curved can be such that pipeline consolidates
There is frequencies go lower, pipeline intrinsic frequency is intensive, is difficult to walk the problem of compressor operating frequency is avoided in pipe direction by change, can be with
Pipeline stress problem is solved with shorter pipeline, piping material cost is greatly reduced, reduces piping manufacture and assembly time.By
The running frequency of compressor 1 can be avoided in air conditioner piping 2, therefore can be avoided air conditioner piping in air-conditioner outdoor unit operational process
2 resonate with compressor 1, reduce dither effect.
In the present embodiment, spring pipeline section 3 is formed by normal straight tube pitch of the laps, pipe diameter size and thin and thick and commonly used copper
Pipe is consistent, and the gap between the diameter and the number of turns and pipeline of pitch of the laps is by copper pipe caliber, circuit design space size and pipeline
Intrinsic frequency codetermines, and needs to guarantee that a whole set of pipeline avoids the compressor operating frequency for determining frequency machine or the vibration for avoiding frequency changer
Biggish frequency is moved, wherein the biggish frequency of the vibration of frequency changer can rule of thumb data obtain, and can also unite by measurement
Meter obtains.
Air conditioner piping 2 is adjusted by using spring pipeline section 3 intrinsic frequency with can be convenient, effectively avoids air conditioner piping 2
Resonance is formed between compressor 1, and vibration decaying is carried out by spring pipeline section 3, reduces the vibration of compressor 1 to air conditioner piping
Influence caused by 2 improves the stress and vibration problem of air conditioner piping 2.
The exhaust outlet of compressor 1 is connected with air conditioner piping 2, and spring pipeline section 3 is connected to the exhaust outlet of compressor 1；And/or
The gas returning port of compressor 1 is connected with air conditioner piping 2, and spring pipeline section 3 is connected to the gas returning port of compressor 1.
Generally, due to which compressor 1 is vibration source, therefore, closer to compressor 1, the pipeline stress of air conditioner piping 2 is got over
Greatly, spring pipeline section 3 is directly connect with the exhaust outlet of compressor 1 or gas returning port at this time, so that it may decaying vibration to greatest extent
Dynamic and dispersive stress, plays optimal effectiveness in vibration suppression.
In the present embodiment, air-conditioner outdoor unit further includes gas-liquid separator 6, and gas-liquid separator 6 is connected to returning for compressor 1
Port, the air inlet of gas-liquid separator 6 are connected with air conditioner piping 2, and spring pipeline section 3 is connected to the air inlet of gas-liquid separator 6.By
In gas-liquid separator 6 be usually a part as compressor 1, it will also be appreciated that be vibration source, therefore by bourdon tube
Section 3 is directly connected to the air inlet of gas-liquid separator 6, can also play the effect of effective decaying vibration and dispersive stress.
Preferably, air conditioner piping 2 further includes straight pipe 4, and spring pipeline section 3 is connected to the exhaust of compressor 1 by straight pipe 4
Mouth and/or gas returning port.Since the stress of straight pipe 4 itself is smaller, so that spring pipeline section 3 is connected by shorter straight pipe 4
It is connected to the exhaust outlet or gas returning port of compressor 1, in the case where facilitating the structure for carrying out air conditioner piping 2 arrangement, can also be dropped
The molding difficulty of low latitude deployment tube 2, while the stress problem and vibration problem of air conditioner piping 2 can be effectively improved.
Air conditioner piping 2 further includes bend loss 5, and bend loss 5 is connected to the one end of spring pipeline section 3 far from compressor 1.Due to bullet
One end vibration stress of the reed pipe section 3 far from compressor 1 is smaller, therefore can be directly connected to the shorter bend loss 5 of length,
It can reduce material cost, while reducing the molding difficulty of air conditioner piping 2.
The spring pipeline section 3 of different tube diameters it is different around loop diameter, bigger around loop diameter, effectiveness in vibration suppression is better, and pitch of the laps is straight
Diameter is smaller, does not have damping effect not only, is also unfavorable for processing (too small around loop diameter, flat tube is easy when coiling).For
The lesser copper pipe of caliber can suitably reduce, therefore the pitch of the laps of spring pipeline section 3 since pipeline itself is flexible preferably around loop diameter
Relationship between diameter D and the bourdon tube caliber d1 of spring pipeline section 3 meets: D >=7d1, thus while meeting damping requirements,
