The flow diversion assembly 100 of an embodiment of the present utility model is described below with reference to the drawings of the specification.

As shown in fig. 1, a flow splitting assembly 100 according to an embodiment of the present utility model includes: a shunt tube 110, a shunt plate 120, and at least one sound attenuating member 130.

The shunt 110 has a fluid inlet 111 and a plurality of fluid outlets 112, as shown in fig. 1, 2, and 3. The fluid inlet 111 and the plurality of fluid outlets 112 are used to communicate between the interior and the exterior of the shunt 110, to ensure that external media can flow into the shunt 110 through the fluid inlet 111 and to ensure that media in the shunt 110 can be expelled through the plurality of fluid outlets 112.

As shown in fig. 1, a diverter plate 120 is disposed within the shunt tube 110, the diverter plate 120 having a plurality of diverter holes 121, the diverter plate 120 being downstream of the fluid inlet 111 and upstream of the plurality of fluid outlets 112. Wherein, the splitter plate 120 is located downstream of the inlet 111 is understood to mean that, during the flow of the external medium, the external medium flows to the inlet 111 first and then to the splitter plate 120; accordingly, the flow splitter plate 120 is located upstream of the plurality of outlets 112. It is understood that during the flow of the external medium, the external medium flows to the flow splitter plate 120 and then to the plurality of outlets 112.

Wherein, the splitter plate 120 is provided with a plurality of splitter holes 121, so that the external medium can effectively pass through the splitter plate 120, and the purpose of splitting the external medium by the splitter plate 120 is achieved.

That is, when the external medium flows in the shunt tube 110, the external medium flows through the shunt plate 120, and then flows to the plurality of liquid outlets 112 and is discharged through the plurality of liquid outlets 112 after being shunted by the shunt plate 120.

It should be noted that, because the external medium is split by the splitter plate 120 before flowing into the plurality of liquid outlets 112, the centrifugal force and the gravity of the external medium flowing into the plurality of liquid outlets 112 can be guaranteed to be approximately the same after the external medium is split, so that the external medium in the splitter 110 can uniformly flow into the plurality of liquid outlets 112, thereby guaranteeing the uniformity of the split and improving the split effect of the splitter assembly 100.

It should be noted that, the external medium may be a refrigerant, and the split flow assembly 100 of the present application splits the refrigerant to ensure that the refrigerant flowing into the plurality of liquid outlet pipes 300 is uniform, thereby ensuring the heat exchange effect of the refrigerant.

In some embodiments, as shown in fig. 1, 2 and 3, the fluid inlet 111 and the plurality of fluid outlets 112 are disposed at opposite ends of the shunt 110, such that when the shunt plate 120 is disposed within the shunt 110, it is ensured that the shunt plate 120 can be positioned downstream of the fluid inlet 111 and upstream of the plurality of fluid outlets 112, facilitating the use of the shunt plate 120 for shunt; meanwhile, through the arrangement, the liquid inlet 111 and the liquid outlets 112 can be arranged at intervals, so that the liquid inlet 111 and the liquid outlets 112 are prevented from interfering with each other during forming, and the forming difficulty of the liquid inlet 111 and the liquid outlets 112 is reduced, namely the forming difficulty of the shunt tube 110 is reduced.

As shown in fig. 1, a sound attenuating member 130 is disposed within the shunt tube 110, with the sound attenuating member 130 being located upstream of the plurality of fluid outlets 112. That is, when the refrigerant flows in the bypass pipe 110, the refrigerant flows to the muffler 130 and then flows to the plurality of liquid outlets 112, and the muffler 130 can reduce noise generated during the flowing process of the refrigerant, thereby reducing noise generated during the operation of the bypass assembly 100, so that the bypass assembly 100 has the advantage of low operation noise.

As can be seen from the above structure, in the flow dividing assembly 100 according to the embodiment of the present utility model, the flow dividing plate 120 is disposed in the flow dividing tube 110, and the flow dividing plate 120 is disposed downstream of the liquid inlet 111 and upstream of the liquid outlets 112, so that when the refrigerant flows from the liquid inlet 111 to the liquid outlets 112, the flow dividing plate 120 can be utilized to divide the refrigerant flowing to the liquid outlets 112, so that the centrifugal force and the gravity of the refrigerant flowing to the liquid outlets 112 are approximately the same, and the refrigerant in the flow dividing tube 110 can uniformly flow to the liquid outlets 112, thereby improving the flow dividing effect of the flow dividing assembly 100.

Meanwhile, the structure of the flow dividing assembly 100 can be optimized by directly using the flow dividing plate 120 to divide the flow, thereby improving the manufacturability of the flow dividing assembly 100 and reducing the production cost of the flow dividing assembly 100.

By arranging the silencing member 130 in the shunt tube 110 and arranging the silencing member 130 to be located at the upstream of the plurality of liquid outlets 112, when the refrigerant flows from the liquid inlet 111 to the liquid outlets 112, the silencing member 130 can be utilized to silence, so that noise generated in the flowing process of the refrigerant is eliminated, the purpose of noise reduction is achieved, and the shunt assembly 100 has the advantage of low working noise.

That is, the flow dividing assembly 100 of the present application has a good flow dividing effect, is convenient to manufacture, has low manufacturing cost, and has low working noise.

It can be appreciated that, compared with the prior art, the shunt tube 110 of the shunt assembly 100 of the present application is provided with the shunt plate 120 and the silencing member 130, and the shunt plate 120 and the silencing member 130 cooperate to improve the shunt effect of the shunt assembly 100 and reduce the noise generated by the shunt assembly 100 during shunt.

In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

In some embodiments, as shown in FIG. 1, at least one sound attenuating member 130 is located downstream of the splitter plate 120. That is, when the refrigerant flows in the shunt tube 110, the refrigerant flows to the shunt plate 120 and then to the muffler 130, so as to shunt and muffler the refrigerant, thereby enabling the refrigerant to uniformly flow to the plurality of liquid outlets 112 and reducing noise generated during the flow of the refrigerant.

Of course, in other embodiments, the sound attenuating member 130 may be disposed upstream of the splitter plate 120. That is, when the refrigerant flows in the bypass pipe 110, the refrigerant flows to the muffler 130 and then to the bypass plate 120, so that the bypass and the muffler of the refrigerant are also achieved.

In some embodiments, as shown in FIG. 1, at least one sound attenuating member 130 is provided on the splitter plate 120. In this way, the muffler 130 can be supported by the splitter plate 120 while reducing noise generated by the refrigerant in the flowing process by using the muffler 130, so that the position stability of the muffler 130 is improved, and the working performance of the muffler 130 is ensured.

In some embodiments, as shown in connection with fig. 4 and 5, the splitter plate 120 is provided with a mounting hole 122, and at least one muffler member 130 is a first muffler member 131, where the first muffler member 131 is disposed in the mounting hole 122. At least one silencing piece 130 is arranged on the flow dividing plate 120, so that the silencing piece 130 is supported by the flow dividing plate 120 conveniently, the position stability of the silencing piece 130 is improved, and therefore noise generated in the flowing process of the refrigerant can be effectively reduced by the silencing piece 130, and the purpose of noise reduction is achieved.

Alternatively, the outer peripheral wall of the first sound damping member 131 is in stop-fit with the inner peripheral wall of the mounting hole 122. That is, the first silencing member 131 is in a stop fit with the mounting hole 122, so that when the first silencing member 131 is arranged on the splitter plate 120, welding of the first silencing member 131 and the splitter plate 120 in production can be omitted, and connection difficulty between the first silencing member 131 and the mounting hole 122 is reduced, so that assembly difficulty between the first silencing member 131 and the splitter plate 120 is reduced, connection quality between the first silencing member 131 and the splitter plate 120 is improved, and the first silencing member 131 is stable relative to the splitter plate 120.

In some embodiments, as shown in fig. 4, the mounting hole 122 is located at a middle portion of the flow dividing plate 120, and the plurality of flow dividing holes 121 are spaced apart in a circumferential direction of the mounting hole 122. The space on the flow dividing plate 120 is reasonably utilized, so that the installation holes 122 and the plurality of flow dividing holes 121 can be simultaneously formed in the flow dividing plate 120, and the first silencing member 131 can be conveniently arranged on the flow dividing plate 120 while the flow dividing plate 120 can effectively divide the refrigerant.

When the first muffler 131 is not disposed on the flow dividing plate 120, as shown in fig. 9 and 10, only the plurality of flow dividing holes 121 are disposed on the flow dividing plate 120, and the plurality of flow dividing holes 121 are spaced apart in the circumferential direction of the flow dividing plate 120, so that the flow dividing plate 120 can effectively divide the refrigerant, and the centrifugal force and the gravity of the refrigerant flowing through the flow dividing plate 120 to the plurality of liquid outlets 112 are approximately the same.

In some embodiments, as shown in connection with fig. 1 and 5, at least one of the muffling members 130 is a second muffling member 132, the second muffling member 132 being located downstream of the manifold 120. The refrigerant split by the splitter plate 120 is ensured to flow through the silencing piece 130, so that noise generated in the flowing process of the refrigerant is reduced by using the silencing piece 130, and the purpose of noise reduction is achieved.

As can be seen from the foregoing, as shown in fig. 1, the flow dividing assembly 100 of the present application includes at least two silencing members 130, wherein one silencing member 130 (second silencing member 132) is located downstream of the flow dividing plate 120, and the other silencing member 130 (first silencing member 131) is disposed on the flow dividing plate 120. The downstream of the splitter plate 120 and the splitter plate 120 are provided with the silencing members 130, so that the number of the silencing members 130 in the splitter tube 110 is increased, and the noise generated in the splitting process of the splitter assembly 100 is effectively reduced.

In some embodiments, as shown in connection with fig. 1 and 5, the second muffler 132 is a stop fit on the side of the manifold 120 adjacent the outlet 112. The second silencing member 132 is arranged at the downstream of the flow dividing plate 120, so that the second silencing member 132 is convenient to silence the refrigerant after the flow dividing plate 120, and noise generated in the flowing process of the refrigerant is reduced.

In addition, the second silencing member 132 is in stop fit with the flow dividing plate 120, so that the second silencing member 132 and the flow dividing plate 120 can be mutually supported, the position stability of the second silencing member 132 and the flow dividing plate 120 is improved, and the working performance of the second silencing member 132 and the flow dividing plate 120 is improved.

Alternatively, as shown in fig. 5, the second sound damping member 132 is provided with a through hole 1321 facing the first sound damping member 131. Here, when the flow dividing assembly 100 includes the first muffler 131 and the second muffler 132, the second muffler 132 is provided with a through hole 1321 facing the first muffler 131, and the through hole 1321 is used for avoiding the refrigerant, so that the refrigerant muffled by the first muffler 131 is prevented from being muffled repeatedly by the second muffler 132, and excessive throttling of the refrigerant by the muffler 130 is prevented, thereby ensuring the heat exchanging effect of the refrigerant.

That is, the muffler 130 of the present application not only achieves the purpose of muffling but also does not excessively throttle the refrigerant.

In some embodiments, as shown in FIG. 1, the outer peripheral wall of the shunt plate 120 and the outer peripheral wall of the second muffler element 132 each are in abutting engagement with the inner peripheral wall of the shunt tube 110. The fixed connection of the splitter plate 120 and the second silencing piece 132 with the splitter tube 110 is realized, so that the splitter plate 120 and the second silencing piece 132 are stable in position in the splitter tube 110, and the working performance of the splitter plate 120 and the second silencing piece 132 is ensured.

That is, the present application utilizes the abutment fit between the outer peripheral wall of the splitter plate 120, the outer peripheral wall of the second muffler 132, and the inner peripheral wall of the splitter tube 110 to achieve the fixed connection between the splitter plate 120, the second muffler 132, and the splitter tube 110, which is simple in connection form, so that the splitter assembly 100 is convenient to process, thereby improving the production and assembly efficiency of the splitter assembly 100.

In some embodiments, the splitter plate 120 and the second silencing member 132 may be separately formed and shaped into standard components, and after the splitter plate 120 and the second silencing member 132 are formed, the splitter plate 120 and the second silencing member 132 are respectively pressed into the splitter tube 110 directly, so that welding of the splitter tube 110 with the splitter plate 120 and the second silencing member 132 during production is avoided, and thus the production difficulty of the splitter assembly 100 is reduced.

In addition, by the assembly mode, the requirement of the space of the current distribution assembly 100 can be reduced.

In some embodiments, as shown in fig. 1, a first limiting protrusion 114 and a second limiting protrusion 115 are disposed in the shunt tube 110, the first limiting protrusion 114 and the second limiting protrusion 115 cooperate to form an assembly space, and the shunt plate 120 and the second muffler 132 are assembled in the assembly space and are in stop fit with the first limiting protrusion 114 and the second limiting protrusion 115, so that the shunt plate 120 and the second muffler 132 can be stably disposed in the shunt tube 110 by using the first limiting protrusion 114 and the second limiting protrusion 115 to cooperate and fix the shunt plate 120 and the second muffler 132.

It should be noted that, when the second muffler 132 is disposed upstream of the splitter plate 120, or the second muffler 132 is disposed downstream of the splitter plate 120 but not in abutting engagement with the splitter plate 120, as shown in fig. 6, 7 and 8, the splitter plate 120 may be only assembled in the assembly space formed by the first limiting protrusion 114 and the second limiting protrusion 115 in a matching manner, and the splitter plate 120 is in abutting engagement with the first limiting protrusion 114 and the second limiting protrusion 115, and the splitter plate 120 is fixed by the matching of the first limiting protrusion 114 and the second limiting protrusion 115, so as to improve the position stability of the splitter plate 120.

In some embodiments, as shown in fig. 1 and 6, the straight distance between the liquid outlet 112 near the flow dividing plate 120 and the flow dividing plate 120 is 4d ₁～8d₁,d₁, which is the diameter of the liquid outlet 112, among the plurality of liquid outlets 112. The linear distance between the liquid outlet 112 near the flow dividing plate 120 and the flow dividing plate 120 can be understood as L1 shown in fig. 1 and 6, that is, l1=4d ₁～8d₁, by which the liquid outlet 112 near the flow dividing plate 120 is spaced from the flow dividing plate 120 and a certain distance between the liquid outlet 112 near the flow dividing plate 120 and the flow dividing plate 120 is ensured, so that a mixing space is formed between the liquid outlet 112 near the flow dividing plate 120 and the flow dividing plate 120, the refrigerant after being split by the flow dividing plate 120 can be mixed again, the mixed refrigerant enters each liquid outlet 112 again, the centrifugal force and the gravity of the refrigerant entering a plurality of liquid outlets 112 are ensured to be approximately the same, and the uniformity of split by the flow dividing assembly 100 is improved.

In a specific example, the linear distance between the liquid outlet 112 near the splitter plate 120 and the splitter plate 120 may be 4d ₁、5d₁、6d₁、7d₁ or 8d ₁.

In some embodiments, as shown in fig. 4 and 9, the number of the flow dividing holes 121 of the flow dividing plate 120 is greater than or equal to 3. The flow dividing effect of the flow dividing plate 120 can be improved while ensuring that the flow dividing plate 120 can effectively divide the refrigerant.

In a specific example, as shown in fig. 4 and 9, the number of the distribution holes 121 on the distribution plate 120 is 4.

Optionally, the aperture d ₂ of the shunt hole 121 is > 1mm. To avoid noise generated by the splitter plate 120 during splitting.

That is, the flow dividing plate 120 of the present application not only can effectively divide the refrigerant, but also can reduce noise generated in the flow dividing process of the flow dividing plate 120, thereby ensuring the working performance of the flow dividing plate 120.

In some embodiments, the shunt assembly 100 further includes a filter (not shown) disposed within the shunt 110 and between the fluid inlet 111 and the shunt plate 120. That is, when the refrigerant flows in the shunt tube 110, the refrigerant flows through the filter element, and then flows to the shunt plate 120, and the filter element is used for filtering the refrigerant flowing through the filter element, so that on one hand, the heat exchange effect of the refrigerant is ensured, and on the other hand, impurities in the refrigerant can be prevented from blocking the shunt plate 120, and the shunting effect of the shunt plate 120 is ensured.

Meanwhile, by arranging the filter element in the shunt tube 110, the arrangement of one filter can be reduced, the production cost of the shunt assembly 100 can be reduced, the occupied space of the shunt assembly 100 can be reduced, and the installation of the shunt assembly 100 is facilitated.

In some embodiments, the filter element is removably disposed within the shunt 110, reducing the difficulty of assembly and disassembly of the filter element, thereby facilitating cleaning and maintenance of the filter element by a user, and ensuring a filtering effect of the filter element.

It can be understood that, in summary, the split-flow component 100 of the present application is the split-flow tube 110, and the split-flow plate 120, the silencing member 130 and the filtering member are integrated in the split-flow tube 110, so that the structural form of the split-flow component 100 is simple while the working performance of the split-flow component 100 is ensured, thereby making the processing of the split-flow component 100 convenient and improving the production and assembly efficiency of the split-flow component 100.
