The length of the hose is set according to actual needs. It will be appreciated that the longer the hose, the better the damping effect. Therefore, it is preferable that the length of the hose is not less than 200 mm. However, the length of the hose is 200mm in consideration of space limitation. Of course, the length of the hose may be selected to be other values, which is not limited in this embodiment.
The type of hose is chosen according to the actual requirements, for example, the hose is a stainless steel hose, a metal hose, a corrugated hose, a rubber hose, or a plastic hose. In order to improve the noise reduction effect, the hose is preferably a rubber hose or a plastic hose.
Among the above-mentioned device of making an uproar falls in refrigerant, damping magnet subassembly 3 includes a plurality of magnet pieces, during the installation, only need with the magnet piece place on capillary 1 can, the installation is comparatively simple and convenient.

The damper tube 2 may be connected in series to the middle or outlet end of the capillary tube 1. Specifically, the damper tube 2 is connected in series to the middle of the capillary tube 1, as shown in fig. 1 and 2, the capillary tube 1 includes a first capillary segment 11 and a second capillary segment 12, and the damper tube 2 is connected in series between the first capillary segment 11 and the second capillary segment 12. It is understood that the first capillary section 11 and the second capillary section 12 communicate through the damper tube 2.
In order to further reduce noise, the damping tube 2 is located outside the foam layer. Thus, the vibration of the outlet of the capillary tube 1 caused by the unstable flow of the refrigerant is effectively attenuated and transmitted to the upstream of the capillary tube 1, and the vibration of the capillary tube 1 in the foaming layer is attenuated to the maximum extent, so that the formation of secondary radiation sound in the foaming layer is prevented, and the noise reduction is further realized.
Preferably, the refrigerant noise reduction device further comprises a transition pipe 4 communicated with the outlet of the capillary tube 1, and the inner diameter of the transition pipe 4 is larger than that of the capillary tube 1. At this time, the capillary tube 1 is communicated with the evaporator 5 through the transition tube 4, and the inner diameter of the transition tube 4 is smaller than the inlet inner diameter of the evaporator 5.
The pipe diameter and the length of the transition pipe 4 are selected according to actual needs, and this embodiment does not limit this.
Further, the transition pipe 4 is a hose. Therefore, the noise can be further reduced, and the noise reduction effect is improved.
In the above-described refrigerant noise reduction device, the noise reduction effect may be improved by another method. Specifically, the refrigerant noise reduction device further comprises a porous noise reduction member 6, and the porous noise reduction member 6 is arranged in the vibration damping pipe 2 and/or the transition pipe 4. For example, as shown in FIG. 2, the porous noise reduction features 6 are disposed within the transition duct 4; as shown in fig. 3, the porous noise reduction member 6 is disposed inside the damper tube 2.
If the porous noise reduction part 6 is arranged in the vibration damping tube 2, the porous noise reduction part 6 is preferentially selected to be arranged at one end of the vibration damping tube 2 close to the capillary tube 1; if the porous noise reduction features 6 are disposed within the transition tube 4, it is preferred that the porous noise reduction features 6 be located at an end of the transition tube 4 proximate to the capillary tube 1.

In the refrigerant noise reduction device, the vibration reduction magnet assembly 3 is preferably located at the joint of the capillary tube 1 and the vibration reduction tube 2 and/or the joint of the capillary tube 1 and the transition tube 4 because the vibration at the sudden change of the tube diameter is large.

It should be noted that, at the outlet of the capillary tube 1, since the refrigerant is vaporized in a large amount and the temperature is low, about-30 ℃, the magnetic force of the damper magnet assembly 3 is not affected by the low temperature, and therefore, the reliability of installing the damper magnet assembly 3 at the outlet of the capillary tube 1 is more significant.
In the above-mentioned refrigerant noise reduction device, the vibration damping tube 2 may also be connected in series to the outlet end of the capillary tube 1, as shown in fig. 3.
In the above-described refrigerant noise reduction device, the inner diameter of the damper tube 2 is larger than the inner diameter of the capillary tube 1. Therefore, the pipe diameter is suddenly changed, the joint of the capillary tube 1 and the damping tube 2 has pressure drop, and the function of releasing pressure in advance can be achieved. When the vibration damping tube 2 is connected in series between the first capillary section 11 and the second capillary section 12, but due to the existence of the second capillary section 12 at the downstream of the vibration damping tube 2, the pressure drop is ensured to be small, the pressure drop at the outlet of the capillary tube 1 can be reduced, the refrigerant burst speed can be effectively reduced, and therefore the burst noise and the tail oscillation of the capillary tube 1 are reduced.
In order to prevent the formation of secondary radiated sound in the foamed layer, the entire capillary 1 is preferably located outside the foamed layer. Specifically, when the capillary tube 1 is communicated with the evaporator 5 through the transition tube 4, the transition tube 4 is positioned in the foaming layer; when the capillary tube 1 communicates with the evaporator 5 through the damper tube 2, the damper tube 2 is located in the foam layer.
Preferably, the vibration reduction magnet assembly 3 includes at least two magnet blocks sequentially distributed along the circumferential direction of the capillary 1. For example, the number of the magnet blocks is two, three, or four. Further, any two magnet blocks are the same in shape and size, and are uniformly distributed along the circumferential direction of the capillary tube 1.
For the sake of simplicity, it is preferable that the vibration reduction magnet assembly 3 includes two magnet blocks, and in this case, the two magnet blocks are disposed symmetrically with respect to the axis of the capillary 1. It will be appreciated that the two magnet blocks are attracted to each other.
The magnet block is curved to increase the force applied to the capillary 1. When the number of the magnet blocks is two, the magnet blocks are preferably selected to be semicircular. At this time, the two magnet blocks are butted to form a sleeve, and the sleeve is in interference fit with the capillary 1.
In practical applications, the magnet block may be selected to have other shapes as long as clamping of the capillary 1 is ensured, and is not limited to the above embodiments.
In order to further optimize the above technical solution, as shown in fig. 7, the refrigerant noise reduction device further includes a bushing 7 disposed between the capillary tube 1 and the damping magnet assembly 3 and capable of tightly connecting the capillary tube 1 and the damping magnet assembly 3.
The bushing 7 may be an elastic bushing such as a rubber bushing or a silicone bushing. For the sake of simplicity of mounting, the above-mentioned bush 7 is a rubber layer attached to the capillary 1. Of course, the bushing 7 may alternatively be a rubber layer attached to the magnet assembly 3.
In the refrigerant noise reduction device, the vibration reduction magnet assemblies 3 can be one group and are only arranged at one position of the capillary tube 1; the damping magnet assemblies 3 can also be at least two groups, and are sequentially distributed along the axial direction of the capillary tube 1, and at the moment, the damping magnet assemblies 3 are arranged at least two positions on the capillary tube 1.
The capillary tube 1 is a copper tube, and the damper tube 2 is a hose, so that the capillary tube 1 and the damper tube 2 are made of different materials. For the convenience of connection, the damper tube 2 and the capillary tube 1 are fixedly connected through a connection assembly. It will be appreciated that the above-described connection assembly communicates between the damper tube 2 and the capillary tube 1.

When the damper tube 2 is connected in series between the first capillary segment 11 and the second capillary segment 12, the capillary tube 1 may be the first capillary segment 11 or the second capillary segment 12.
Preferably, the first connecting piece 8 and the second connecting piece 9 are fixedly connected through thread fit, the first connecting piece 8 and the capillary tube 1 are fixedly connected through interference fit, and the second connecting piece 9 and the damping tube 2 are fixedly connected through interference fit.
In the above-mentioned connection assembly, the first connection member 8 and the second connection member 9, the first connection member 8 and the capillary tube 1, and the second connection member 9 and the damping tube 2 may also be fixed and connected by other methods, which is not limited to the above-mentioned embodiment.
Further, the first connecting member 8 has a stepped hole, and a large hole of the stepped hole is in interference fit with the capillary tube 1. Therefore, the installation of the capillary tube 1 is realized through the stepped hole, the axial limiting of the capillary tube 1 is also realized, the insertion depth of the capillary tube 1 can be strictly limited, and the control of the vibration of the tail end of the capillary tube 1 is realized through the strict matching of the inner diameter of the large hole of the stepped hole and the outer diameter of the capillary tube 1.

Because damping pipe 2 is the hose, when screwing up first connecting piece 8 and second connecting piece 9 of screw-thread fit, damping pipe 2 is easy to be out of shape, for reducing damping pipe 2's deformation, the one end of first connecting piece 8 inserts in damping pipe 2 and with damping pipe 2 interference fit. In this way, the portion of the first connecting member 8 inserted into the damper tube 2 achieves support of the damper tube 2, so that deformation of the damper tube 2 is reduced, and even deformation of the damper tube 2 can be avoided.
In order to facilitate the connection of the damper tube 2 and the first connector 8, the portion of the first connector 8 inserted into the damper tube 2 is tapered in the insertion direction thereof.
Specifically, the first connecting piece 8 includes a capillary connecting section 81, a first main connecting section 82 and a first vibration damping connecting section 83 which are connected in sequence, and the second connecting piece 9 includes a second main connecting section 91 and a second vibration damping connecting section 92 which are connected in sequence, wherein the capillary connecting section 81 is sleeved on the capillary tube 1, the stepped hole is arranged in the capillary connecting section 81, and a large hole of the stepped hole is in interference fit with the capillary tube 1; the first main connecting section 82 is fixedly connected with the second main connecting section 91, specifically, the second main connecting section 91 is sleeved outside the first main connecting section 82, and the second main connecting section 91 is in threaded fit with the first main connecting section 82; the damping pipe 2 is sleeved on the first damping connecting section 83, the damping pipe 2 is in interference fit with the first damping connecting section 83, and further, the first damping connecting section 83 is gradually reduced from one end close to the first main connecting section 82 to one end far away from the first main connecting section 82; the second vibration damping connecting section 92 is sleeved on the vibration damping pipe 2, and the second vibration damping connecting section 92 is in interference fit with the vibration damping pipe 2.
Of course, one end of the first connecting member 8 may be inserted into the damper tube 2 and transition-fitted into the damper tube 2, and is not limited to the above-described embodiment.
