Describe to be used for parallel-flow heat exchanger (figure according to the utility model first aspect embodiment below with reference to Fig. 1-Fig. 3
It is not shown) header 100.
As shown in Figure 1-Figure 3, according to the header for parallel-flow heat exchanger of the utility model first aspect embodiment
100, including：First body 1 and the second body 2.
Second body 2 is located in the first body 1, is limited between the internal perisporium of the periphery wall of the second body 2 and the first body 1
Go out sound-absorbing chamber 10a.For example, as shown in Figure 1-Figure 3, the first body 1 and the second body 2 can be it is columnar structured, first
Body 1 is set in the outside of the second body 2, and the first body 1 and the second body 2 are preferably coaxially disposed, the internal diameter of the first body 1
More than the external diameter of the second body 2, sound-absorbing chamber is limited between the internal perisporium of the periphery wall of the second body 2 and the first body 1
10a, sound-absorbing chamber 10a can reduce or even eliminate the noise produced in header 100 due to the flowing of refrigerant, lifting
The comfortableness that user uses.It is understood that the shape of cross section of the first body 1 and the second body 2 can also be other
Loop configuration (such as rectangle), and the cross-sectional area of the first body 1 and the second body 2 can be equal everywhere vertically, or
The change that size is separated by can also be presented along the axial direction of header 100 in the cross-sectional area of first body 1 and the second body 2, make collection
The size of cross section is undergone mutation in flow tube 100, as shown in Figure 3.
According to the header 100 for parallel-flow heat exchanger of the utility model embodiment, by the way that header 100 is set
It is to include limiting sound absorption cavity between the double-deck form of tubes of the first body 1 and the second body 2, and the first body 1 and the second body 2
Room 10a, can reduce or even eliminate the noise produced in header 100 due to the flowing of refrigerant, so as to lift use
The comfortableness that family is used.
In a specific embodiment of the present utility model, as shown in figure 1, being vacuumized in sound-absorbing chamber 10a.Due to sound
Propagation need to vacuumize in medium, sound-absorbing chamber 10a and can effectively cut off what the noise of cold-producing medium stream movable property life was outwards propagated
Approach, so as to eliminate the flow noise of refrigerant, improves the comfortableness that user uses.
Further, there is vacuum orifice 10b on the side wall of the first body 1.For example, as shown in figure 1, vacuum orifice 10b
Connected with sound-absorbing chamber 10a, so as to be vacuumized by vacuum orifice 10b to sound-absorbing chamber 10a, facilitate sound absorption cavity
Room 10a's vacuumizes.Wherein, vacuum-pumping tube 5 can be set at vacuum orifice 10b, in order to (not shown with vaccum-pumping equipment
Go out) connection.
Alternatively, as shown in figure 1, vacuum orifice 10b is located at the center on the length direction of the first body 1.Thus, afflux
Pipe 100 substantially can be on vacuum orifice 10b Central Symmetry, it is ensured that header 100 it is attractive in appearance, and can improve and vacuumize
Speed.
In another specific embodiment of the present utility model, sound-absorbing medium 3 is provided with sound-absorbing chamber 10a.For example, as schemed
Shown in 2, sound-absorbing medium 3 is filled in sound-absorbing chamber 10a, sound-absorbing medium 3 can absorb the energy of sound wave, reach reduction refrigerant
Flow noise effect.
Alternatively, sound-absorbing medium 3 is sound-absorbing sponge, mineral wool etc..Due to the sound-absorbing such as sound-absorbing sponge, mineral wool medium 3
The rambling passage that inside is constituted containing countless micro-pores, the noise of refrigerant flowing enters these passages, and makes an uproar
The sound wave of sound continues to propagate in passage, and the passage in the sound-absorbing medium 3 such as sound-absorbing sponge, mineral wool has friction to sound wave and damped
Effect, thus, sound-absorbing sponge, mineral wool etc. attract medium 3 acoustic energy of noise can be converted into heat energy, so as to reduce
Acoustic energy, and then the purpose of the flow noise of reduction refrigerant is reached, moreover, 3 pairs of collection of the sound-absorbing such as sound-absorbing sponge, mineral wool medium
The corrosion-free effect of flow tube 100, at the same the change by a small margin of temperature on its noise reduction without influence.It is, of course, understood that inhaling
Sound medium 3 can also be other porous sound absorbing materials, and be not limited to sound-absorbing sponge, mineral wool.For example, sound-absorbing medium 3 can be with
It is other kinds of sound-absorbing material such as sound deadening coating, as long as the effect of noise reduction can be reached, and makees to header 100 is corrosion-free
With the change by a small margin of, temperature on its noise reduction without influence.
In some embodiments of the present utility model, it is formed with the first body 1 along the length direction interval of the first body 1
It is formed with along the length direction spaced multiple second of the second body 2 and leads on the multiple first through hole set, the second body 2
Hole 21, multiple first through hole and multiple second through holes 21 are corresponded.For example, as shown in Figure 1-Figure 3, first through hole and second is led to
The size in hole 21 can be with equal, thus, when header 100 is applied to parallel-flow heat exchanger, and the flat tube of parallel-flow heat exchanger can be with
First through hole and the second through hole 21 are sequentially passed through, to facilitate the flat tube of parallel-flow heat exchanger and the connection of header 100.
Further, the two ends of the first body 1 and the second body 2 are respectively equipped with end cap 4 to block the first body 1 and second
The two ends of body 2.For example, as depicted in figs. 1 and 2, two end caps 4 are respectively provided at the axial two ends of header 100, to block
The two ends of sound-absorbing chamber 10a between one body 1 and the second body 2, thus, sound-absorbing chamber 10a are substantially in enclosed construction, so that
The flow noise of refrigerant is reduce further, and when sound-absorbing medium 3 is fluid such as sound deadening coating, sound-absorbing can be facilitated to be situated between
The splendid attire of matter 3.
According to the parallel-flow heat exchanger of the utility model second aspect embodiment, including according to the utility model above-mentioned first
The header 100 for parallel-flow heat exchanger of aspect embodiment.
Specifically, parallel-flow heat exchanger can also include multiple flat tubes, fin and the first header, wherein, multiple flat tubes
One end sequentially pass through after the first through hole of the first body 1 and the second through hole 21 of the second body 2 with connecting inside the second body 2
Logical, the other end of multiple flat tubes is connected with the first header, and fin is located between two neighboring flat tube to strengthen heat transfer effect.
When parallel-flow heat exchanger works, refrigerant is passed through to flow after the dispensing orifice in the distribution pipe in header 100
Enter in header 100, and be assigned to through above-mentioned one end of multiple flat tubes in multiple flat tubes, refrigerant is in flat Bottomhole pressure
During, the air in outside of the refrigerant by the wall, fin of flat tube with flowing through parallel-flow heat exchanger is exchanged heat, final system
Cryogen can flow out from the first header.Meanwhile, what refrigerant was produced during being flowed into through dispensing orifice in header 100
Flow noise, can be absorbed by sound-absorbing chamber 10a or cut off its route of transmission, so as to reduce or even eliminate the flowing of refrigerant
Noise, improves the comfortableness that user uses.
According to the parallel-flow heat exchanger of the utility model embodiment, by using above-mentioned header 100, reduction even disappears
Except the flow noise of refrigerant, the comfortableness that user uses is improved.
