In the prior art, the liquid separating device usually adopts a flow dividing pipeline device, however, under different working conditions, the problem of uneven distribution usually occurs to the distribution of the refrigerant by the flow dividing pipeline device, so that the amount of the refrigerant entering each flow path in the multi-flow path heat exchanger is different, the heat exchange efficiency of the multi-flow path heat exchanger is reduced, and the air conditioning effect of the air conditioner is reduced.

In order to improve the above-mentioned problem, in other words, in order to improve the technical problem that the heat exchanger heat exchange efficiency is not high because divide the inhomogeneous heat exchanger that leads to of liquid piping arrangement, and leads to the air conditioning effect of air conditioner to reduce, provide the liquid device 50 and adopted this air conditioner who divides liquid device 50 in this application.

In an embodiment of the present application, referring to fig. 1 and fig. 2, the liquid separating device 50 includes a liquid inlet pipe 200, a liquid separating assembly 100, and a plurality of liquid outlet pipes 300. The liquid inlet pipe 200 and the plurality of liquid outlet pipes 300 are connected to the liquid separating assembly 100, the liquid inlet pipe 200 is used for introducing the refrigerant into the liquid separating assembly 100, the liquid separating assembly 100 is used for uniformly distributing the refrigerant to the plurality of liquid outlet pipes 300, and the plurality of liquid outlet pipes 300 are led out to the plurality of flow paths of the multi-flow-path heat exchanger 10, in other words, the plurality of liquid outlet pipes 300 are respectively connected to the plurality of flow paths of the multi-flow-path heat exchanger 10. It should be understood that, in the case of switching the flow direction of the refrigerant, the refrigerant may also flow from the multi-flow heat exchanger 10 to the liquid separation device 50, in this case, the refrigerant in the plurality of flow paths of the multi-flow heat exchanger 10 is introduced into the liquid separation assembly 100 from the plurality of liquid outlet pipes 300, respectively, and the refrigerant is collected in the liquid separation assembly 100 and then is led out from the liquid inlet pipe 200.

The liquid separation assembly 100 comprises an outer shell 110, a first liquid separation cavity 111 and a plurality of second liquid separation cavities 112 are arranged inside the outer shell 110, and the plurality of second liquid separation cavities 112 are arranged around the first liquid separation cavity 111. A plurality of liquid separation holes 121 are formed in the peripheral wall surrounding the first liquid separation cavity 111; any one of the second liquid-dividing chambers 112 communicates with the first liquid-dividing chamber 111 through at least one liquid-dividing hole 121. The liquid inlet pipe 200 is connected to the outer shell 110, and an internal passage of the liquid inlet pipe 200 is communicated with the first liquid separation chamber 111; a plurality of effluent tubes 300 are connected to outer housing 110, and any one of second dispense chambers 112 is in communication with the internal channel of at least one effluent tube 300.

As described above, in the case where the liquid distribution pipe is connected to the air conditioner, the refrigerant can be introduced from the liquid inlet pipe 200 into the first liquid distribution chamber 111, and the plurality of second liquid distribution chambers 112 are disposed around the first liquid distribution chamber 111, which means that the first liquid distribution chamber 111 and the plurality of second liquid distribution chambers 112 are substantially flat, and the plurality of second liquid distribution chambers 112 are respectively communicated with the first liquid distribution chamber 111 through the liquid distribution holes 121, so that the refrigerant in the first liquid distribution chamber 111 can uniformly flow to the plurality of second liquid distribution chambers 112 around, and the refrigerant introduced into the plurality of second liquid distribution chambers 112 from the first liquid distribution chamber 111 can be uniformly distributed, thereby uniformly distributing the refrigerant, and improving the technical problem of non-uniform liquid distribution of the liquid distribution pipes in the prior art. Based on this, can ensure that the heat exchanger has good heat transfer ability, improve the heat exchange efficiency of heat exchanger.

It is worth noting that, in some embodiments of the present application, in order to facilitate the flow of the refrigerant, in the case where the liquid dividing device 50 is installed in an air conditioner, the first liquid dividing chamber 111 and the plurality of second liquid dividing chambers 112 are located substantially on the same plane, in other words, the plurality of second liquid dividing chambers 112 are arranged around the first liquid dividing chamber 111 in a horizontal direction, thereby enabling the refrigerant entering the first liquid dividing chamber 111 to flow into the plurality of second liquid dividing chambers 112 uniformly and rapidly. Under the condition that the refrigerant enters the first liquid dividing cavity 111 through the liquid inlet pipe 200 and then enters the plurality of second liquid dividing cavities 112 from the first liquid dividing cavity 111, the refrigerant can be rapidly and uniformly distributed to the plurality of second liquid dividing cavities 112; and under the condition that the refrigerant is guided into the second liquid dividing chambers 112 through the liquid outlet pipes 300 and then is collected into the first liquid dividing chamber 111 from the liquid dividing chambers, the refrigerant can be collected quickly and efficiently, and the refrigerant can be guided out through the liquid inlet pipe 200. In addition, by disposing the first liquid-separation chamber 111 and the plurality of second liquid-separation chambers 112 on the same plane, it is possible to prevent refrigerant from being trapped in the first liquid-separation chamber 111 and the second liquid-separation chamber 112. The first liquid separation cavity 111 and the plurality of second liquid separation cavities 112 are located on the same plane, which can be shown that, under the condition that the liquid separation device 50 is normally installed, the bottom wall of the first liquid separation cavity 111 and the bottom walls of the plurality of second liquid separation cavities 112 are located on the same plane; alternatively, the center of the first distribution chamber 111 and the centers of the plurality of second distribution chambers 112 may be located in the same plane.

Of course, referring to fig. 3 and fig. 4 in combination, in other embodiments of the present application, the first liquid-dividing chamber 111 and the plurality of second liquid-dividing chambers 112 in the liquid-dividing assembly 100 may be arranged in other manners. For example, the plurality of second liquid-dividing chambers 112 are located in the same plane, and the plurality of second liquid-dividing chambers 112 are lower than the first liquid-dividing chamber 111, thereby allowing the refrigerant in the first liquid-dividing chamber 111 to fall into the plurality of second liquid-dividing chambers 112.

To form the first dispensing chamber 111 and the plurality of second dispensing chambers 112 in the dispensing assembly 100, in some embodiments of the present application, the dispensing assembly 100 further includes a diverter 120 and a plurality of dividers 130. The flow dividing member 120 and the plurality of dividing members 130 are disposed inside the outer case 110. The flow divider 120 is disposed annularly, the inner side of the flow divider 120 encloses a first liquid dividing cavity 111, and a plurality of liquid dividing holes 121 are formed in the flow divider 120. A plurality of dividing members 130 are attached to the outside of the flow dividing member 120 at intervals to form a plurality of second flow dividing chambers 112. That is, one end of the partition 130 is connected to the outside of the flow dividing member 120, and the other end is connected to the outer case 110, thereby forming one second branch chamber 112 between two adjacent partition 130, and in the case where a plurality of partition 130 are disposed around the flow dividing member 120, a plurality of second branch chambers 112 surrounding the first branch chamber 111 are formed.

In some embodiments of the present application, the hole diameter of the liquid separation hole 121 is small, and the number of the liquid separation holes 121 is large, so that any one of the second liquid separation chambers 112 is communicated with the first liquid separation chamber 111 through the plurality of liquid separation holes 121 with small hole diameters, and thus, when a refrigerant is introduced into the first liquid separation chamber 111, the refrigerant can be introduced into the second liquid separation chamber 112 from the plurality of liquid separation holes 121. Through the arrangement of the plurality of liquid distribution holes 121 with small hole diameters, a small difference in conduction area between any one of the second liquid distribution chambers 112 and the first liquid distribution chamber 111 can be easily realized, and it can also be seen that the same conduction area between any one of the second liquid distribution chambers 112 and the first liquid distribution chamber 111 can be easily realized, so that the refrigerant in the first liquid distribution chamber 111 is uniformly distributed into the plurality of second liquid distribution chambers 112, the assembly requirement of the flow distribution member 120 can be reduced, the uniform distribution of the refrigerant can be realized after the flow distribution member 120 is simply installed, and the problem of uneven distribution of the refrigerant in the prior art is solved.

Of course, in other embodiments of the present application, the arrangement of the liquid distribution holes 121 on the flow divider 120 may also be different, for example, the number of the liquid distribution holes 121 opened on the flow divider 120 is the same as the number of the second liquid distribution chambers 112, and any one of the second liquid distribution chambers 112 is communicated with the first liquid distribution chamber 111 through one liquid distribution hole 121.

Optionally, in some embodiments of the present application, the shunt 120 is circular. The dividing members 120 are surrounded into a circular ring shape, so that not only can a plurality of separating members 130 be conveniently connected with the dividing members 120 to form a plurality of uniform second liquid dividing cavities 112, but also uniform distribution of the refrigerant can be conveniently realized. And, in the case that the flow dividing member 120 is surrounded by a circular ring, the liquid inlet pipe 200 may correspond to the center of the circular ring surrounded by the flow dividing member 120, so that the distance from the refrigerant introduced by the liquid inlet pipe 200 to each position of the flow dividing member 120 is the same, so that the refrigerant can uniformly flow into the plurality of second liquid dividing chambers 112 surrounding the first liquid dividing chamber 111, which is also beneficial to uniform distribution of the refrigerant.

It should be understood that in other embodiments of the present application, the splitter 120 may be enclosed in other shapes, such as a regular polygon or a special shape. It should be noted that, in the case that the flow dividing member 120 is formed in a special shape, the special shape formed by the flow dividing member 120 is preferably a central symmetrical pattern or a symmetrical pattern.

Further, optionally, in some embodiments of the present application, the separator 130 is curved in a wave shape. The wave shape is that the separator 130 is bent to form at least two arcs, and the centers of the two arcs are different. By bending the partition 130 in a wave shape, the refrigerant may impact the partition 130 several times when being introduced into the second liquid separation chamber 112, and thus may be introduced into the liquid outlet pipe 300 after several bounces of the partition 130, thereby reducing the flow velocity of the refrigerant and preventing the refrigerant from flowing backward.

Of course, in other embodiments of the present application, the divider 130 may also be formed in other shapes. For example, the partition 130 is curved in an arc shape. As another example, the separator 130 extends in a straight line. For another example, the dividing member 130 may be bent, and the dividing member 130 may be regarded as extending along a broken line path. Also for example, the separator 130 is bent in a shape of a profile or the like.

In some embodiments of the present application, the flow divider 120 and the plurality of separators 130 are each plate-shaped, and the flow divider 120 and the plurality of separators 130 may be mounted on the outer case 110 by welding. Of course, in other embodiments of the present application, the connection manner of both the flow dividing member 120 and the dividing member 130 with the outer shell 110 can also adopt other manners, for example, the flow dividing member 120 and the dividing member 130 are adhered to the outer shell 110; for another example, the flow divider 120, the separating element 130 and the outer shell 110 are integrally connected; also for example, the shunt member 120 and the spacer member 130 can be removably attached to the outer housing 110 by a snap, screw, or plug connection, among others.

The liquid outlet pipe 300 and the liquid inlet pipe 200 are respectively connected to two opposite sides of the outer housing 110. Through this mode of setting, under the condition that a plurality of drain pipes 300 are connected with the evaporimeter, can avoid a plurality of drain pipes 300 to influence the connection of feed liquor pipe 200 and other pipelines, also make things convenient for the maintenance of feed liquor pipe 200 and a plurality of drain pipes 300 certainly.

Under general conditions, under the condition that liquid separating device 50 is installed in refrigerating system 1, the pipeline of connecting feed liquor pipe 200 and multithread way heat exchanger 10 are located the relative both sides of liquid separating assembly 100 respectively, from this, connect feed liquor pipe 200 and a plurality of drain pipe 300 respectively in the relative both sides that set up on shell body 110, can conveniently divide the installation of liquid device 50, also make things convenient for refrigerating system 1's pipeline calandria simultaneously.

Of course, in other embodiments of the present application, the liquid inlet pipe 200 and the plurality of liquid outlet pipes 300 may be disposed on the same side of the outer housing 110; alternatively, liquid inlet pipe 200 and a portion of liquid outlet pipe 300 are disposed on the same side of outer housing 110. In addition, in the above-described embodiment of the present application, the liquid inlet pipe 200 and the liquid outlet pipe 300 are disposed at opposite sides of the outer case 110, thereby making the liquid inlet pipe 200 and the liquid outlet pipe 300 substantially parallel; it should be understood that in some embodiments of the present application, liquid inlet pipe 200 and liquid outlet pipe 300 may be disposed on two adjacent sides of outer housing 110, such that liquid inlet pipe 200 and liquid outlet pipe 300 are disposed at an angle.

In some embodiments of the present application, please refer to fig. 2 and 3 in combination, the outer housing 110 includes a housing main body 113 and a cover plate 114; the first liquid distribution chamber 111 and the plurality of second liquid distribution chambers 112 are provided inside the case main body 113, in other words, the flow dividing member 120 and the plurality of partition members 130 are provided inside the case main body 113, and enclose the first liquid distribution chamber 111 and the plurality of second liquid distribution chambers 112 inside the case main body 113. The cover plate 114 covers the shell body 113 to cover the first liquid separation chamber 111 and the plurality of second liquid separation chambers 112; thereby enabling the first branch liquid chamber 111 and the plurality of second branch liquid chambers 112 to be sealed to prevent liquid leakage. In the case where the cover plate 114 is coupled to the case main body 113, the flow dividing member 120 and the plurality of dividing members 130 are coupled to the cover plate 114, thereby allowing communication between the first and second liquid dividing chambers 111 and 112 only through the liquid dividing holes 121. In addition, the liquid inlet pipe 200 is connected to the middle of the cover plate 114; a plurality of effluent channels 300 are connected to the side of housing body 113 remote from cover plate 114.

The cover plate 114 and the case main body 113 may be connected in such a manner that the cover plate 114 is connected to the case main body 113 by welding. Alternatively, the cover plate 114 is connected to the housing main body 113 by a screw connection or a snap connection, so that the cover plate 114 can be conveniently detached, thereby facilitating the maintenance of the liquid separation device 50. Still alternatively, the cover plate 114 is bonded to the case main body 113 by means of bonding. Of course, in other embodiments of the present application, the connection manner of the cover plate 114 and the shell main body 113 is not limited to the above connection manner, and the connection of the cover plate 114 and the shell main body 113 may also be achieved through a magnetic connection, a thermal fusion connection, and the like.

Optionally, in some embodiments of the present application, a plurality of effluent channels 300 are disposed proximate an outer edge of housing body 113. It can also be seen that the liquid outlet pipe 300 is connected to the shell main body 113 at a position at an end of the second liquid distribution chamber 112 far from the first liquid distribution chamber 111, and in a case where the refrigerant is distributed from the first liquid distribution chamber 111 to a plurality of second liquid distribution chambers 112, the refrigerant can flow in a direction of the second liquid distribution chamber 112 far from the first liquid distribution chamber 111, and since the partition 130 is bent in a wave shape, the refrigerant can impact the partition 130 multiple times and be rebounded by the partition 130, a flow velocity of the refrigerant can be slowed down, and backflow of the refrigerant can be prevented, and the refrigerant can have a sufficient flow space to facilitate uniform distribution of the refrigerant.

Of course, in order to facilitate the refrigerant to flow in second liquid-dividing chamber 112, liquid outlet pipe 300 is disposed at an end of second liquid-dividing chamber 112 far from first liquid-dividing chamber 111, so that the position where liquid outlet pipe 300 is connected to case main body 113 is disposed near the outer periphery of case main body 113, and thus it appears that a plurality of liquid outlet pipes 300 are disposed near the outer edge of case main body 113. In addition, by disposing the plurality of liquid outlet pipes 300 close to the outer edge of the case main body 113, the distance between the plurality of liquid outlet pipes 300 may be increased, thereby facilitating the connection of the plurality of liquid outlet pipes 300 with the plurality of flow paths of the multi-flow-path heat exchanger 10.

It should be understood that in other embodiments of the present application, since first liquid distribution chamber 111 has a certain area and second liquid distribution chamber 112 is disposed around first liquid distribution chamber 111, a plurality of liquid outlet pipes 300 can be represented as being disposed around first liquid distribution chamber 111 in the case where liquid outlet pipes 300 are disposed at any positions corresponding to second liquid distribution chamber 112, in other words, even though liquid outlet pipes 300 are disposed corresponding to the middle portion of second liquid distribution chamber 112, liquid outlet pipes 300 can be considered as being disposed near the outer edge of housing main body 113.

In addition, in order to improve the efficiency of introducing the refrigerant from the first liquid-dividing chamber 111 into the plurality of second liquid-dividing chambers 112, the liquid-dividing assembly 100 further includes a flow guide member 400; the flow guide part 400 is arranged in the first liquid separation cavity 111, and the flow guide part 400 is conical; the small end of the guide 400 is disposed toward the liquid inlet pipe 200. In the case where the flow guide member 400 is provided, it is also possible to ensure that the refrigerant is uniformly distributed into the plurality of second partial liquid chambers 112 surrounding the first partial liquid chamber 111 by the flow guide member 400 in the case where the refrigerant is introduced into the first partial liquid chamber 111 from the liquid inlet pipe 200, ensuring that the refrigerant can be uniformly distributed.

The small end of the flow guide member 400 is disposed toward the liquid inlet pipe 200, and the tapered surface of the flow guide member 400 is disposed toward the liquid inlet pipe 200, so that when the refrigerant is introduced into the first branch chamber 111 from the liquid inlet pipe 200, the refrigerant is received by the tapered surface of the flow guide member 400, and the refrigerant flows toward the flow guide member 120 under the guiding action of the tapered surface of the flow guide member 400, so that the refrigerant flows toward the plurality of second branch chambers 112, and the refrigerant can be promoted to flow toward the plurality of second branch chambers 112, thereby achieving the purpose of improving the refrigerant distribution efficiency.

Of course, in other embodiments of the present application, the flow guiding member 400 may have a spherical shape, and the spherical surface of the flow guiding member 400 may also provide a guiding function to the refrigerant, so that the refrigerant flows toward the plurality of second liquid dividing chambers 112.

Optionally, in some embodiments of the present application, the flow guide member 400 has a conical shape, so that the conical surface of the flow guide member 400 can uniformly distribute the refrigerant, and the refrigerant can uniformly flow toward the flow dividing member 120, and the distribution of the refrigerant can be uniformly accomplished. Of course, in other embodiments of the present application, the flow guide 400 may also be formed in a pyramid shape, such as a rectangular pyramid, a pentagonal pyramid, or a hexagonal pyramid. In addition, the flow guide 400 may also be formed in a frustum shape.

In order to improve the guiding function of the flow guide 400, the cross section of the flow guide 400 formed along the axis thereof is triangular, and the angle of the angle formed by the small end of the flow guide 400 in the cross section is an acute angle. Optionally, the value range of the acute angle is greater than or equal to 30 ° and less than 90 °; that is, the acute angle may take a value of 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, 60 °, 65 °, 70 °, 75 °, 80 °, or 85 °, etc. In other words, in some embodiments of the present application, the flow guide 400 is conical, and the angle of the cone angle of the small end of the conical flow guide 400 is acute. Therefore, the small end of the flow guide member 400 can conveniently divide the refrigerant introduced by the liquid inlet pipe 200, and can also conveniently distribute the refrigerant uniformly, so that the refrigerant can be uniformly introduced into the plurality of second liquid dividing chambers 112.

It should be understood that the provision of the baffle 400 may be eliminated in other embodiments of the present application.
