Referring to fig. 1 to 9, a dispenser according to an embodiment of the present disclosure includes a body 10, a flow divider 20, and a throttling element 30, where the body 10 includes a main channel 101, the flow divider 20 is disposed in the main channel 101 and includes a plurality of flow dividing channels 201, and the flow dividing channels 201 are communicated with the main channel 101 to divide a fluid flowing out of the main channel 101; the throttling element 30 is arranged in the main channel 101, the throttling element 30 is in contact with the inflow end side of the flow dividing channel 201, the throttling element 30 is configured with a plurality of hollow parts 301, the hollow parts 301 and the flow dividing channel 201 define a throttling opening 302, and the throttling opening 302 is used for throttling fluid flowing to the flow dividing channel 201.

By adopting the liquid separator provided by the embodiment of the disclosure, the throttling element 30 is arranged between the main channel 101 and the flow dividing channel 201, namely, the throttling opening 302 is used for throttling the fluid flowing to the flow dividing channel 201, so that the content of the fluid flowing through each flow dividing channel 201 is different, wherein the throttling of each flow dividing channel 201 is adjusted according to the working condition of the corresponding flow path, thereby realizing that the content of the fluid flowing into the corresponding flow path from the flow dividing channel 201 is different and is adaptive to the working condition of the corresponding flow path, ensuring that the heat exchange effect of each flow path is basically the same, so as to achieve the purpose of uniform heat exchange, and further improving the overall heat exchange efficiency of the heat exchanger; meanwhile, the problem of increasing the accommodating space caused by the use of the capillary can be avoided.

Optionally, the main channel 101 is a cylindrical structure. The main channel 101 comprises an inlet 103 and an outlet 104 opposite the inlet 103, wherein the cross-sectional area of the inlet 103 is smaller than the cross-sectional area of the outlet 104 and the cross-sectional area of the inlet 103 is smaller than the cross-sectional area of the main channel 101. Thus, after the refrigerant flows into the main passage 101 through the inlet 103, the space of the main passage 101 becomes large, the pressure of the refrigerant becomes small, and the impact force on the flow dividing member 20 and the throttling member 30 is reduced; which helps to improve the stability of the flow divider 20 and flow restriction 30 during use.

Alternatively, the flow divider 20 may be removably attached, or fixedly attached, to the main channel 101. The plurality of flow dividing channels 201 of the flow dividing member 20 are uniformly spaced, which helps to ensure that the flow dividing member 20 is uniformly stressed during operation.

The throttle 30 is provided in the main passage 101 and the throttle 30 is in contact with the inflow end side of the branch passage 201, which can be understood as: the fluid in the main passage 101 is prevented from flowing into the branch passage 201 without being throttled by the throttle 30, that is, the fluid in the main passage 101 is prevented from flowing into the branch passage 201 through the gap between the throttle 30 and the branch passage 201. The throttle member 30 abuts on the inflow end side of the flow dividing passage 201, so that a gap between the throttle member 30 and the flow dividing passage 201 is avoided as much as possible.

The fluid in the main channel 101 flows into the branch channel 201 through the hollow part 301 and the throttle opening 302 defined by the branch channel 201, so as to achieve the purpose of throttling. Wherein, different flow dividing channels 201 correspond to different chokes 302. The flow area of each orifice 302 is set according to the actual condition of the flow path corresponding to the flow dividing channel 201. The orifice 302 may be understood as a flow area where the hollow portion 301 and the flow dividing channel 201 are overlapped.

Alternatively, the hollowed-out portion 301 may be a regular pattern or an irregular pattern. For example, the hollowed-out portion 301 may be circular or fan-shaped. The shapes of the hollow portions 301 may be the same, different, or partially the same.

Alternatively, the orifice 30 has a plate shape, and the flow areas of the partial hollows 301 are the same.

The shunting channels 201 of the shunting pieces 20 are uniformly distributed at intervals, the flow areas of the parts of the hollowed parts 301 are the same, and after the throttling pieces 30 are matched with the shunting pieces 20, the flow areas of the throttling holes 302 defined by each shunting channel 201 and the corresponding hollowed parts 301 are different, the throttling holes 302 with different flow areas correspond to the flow paths matched with the throttling holes, so that the heat exchange effect of each flow path is basically the same, the purpose of uniform heat exchange is achieved, and the overall heat exchange efficiency of the heat exchanger is improved.

The number of the hollow parts 301 is the same as that of the flow dividing channels 201, and the arrangement of the hollow parts 301 is matched with that of the flow dividing channels 201. Thus, each flow dividing channel 201 can be ensured to form the throttling opening 302 matched with the flow path, so that the content of the fluid flowing through the corresponding flow path in unit time is different, and the heat exchange effect of each flow path is ensured to be basically the same, so that the aim of uniform heat exchange is fulfilled.

Optionally, the flow area of the hollowed-out portion 301 is greater than or equal to the flow area of the flow dividing channel 201.

The flow area of the hollow part 301 is larger than or equal to the flow area of the flow dividing channel 201, so that the flow area of the throttling opening 302 defined by the hollow part 301 and the flow dividing channel 201 is smaller than or equal to the flow area of the flow dividing channel 201, and the purpose of throttling the fluid flowing to the flow dividing channel 201 is achieved.

When the flow area of the hollow portion 301 is larger than that of the flow dividing channel 201, the hollow portion 301 and the flow dividing channel 201 may partially overlap to define the throttle opening 302. Alternatively, the entire flow dividing channel 201 is located in the region surrounded by the hollow portion 301, so that the flow area of the orifice 302 is the same as the flow area of the flow dividing channel 201.

When the partial areas of the flow dividing channel 201 and the hollow portion 301 are overlapped, the edge of the flow dividing channel 201 is abutted against the edge of the hollow portion 301.

Optionally, each of the flow dividing channels 201 corresponds to a hollow portion 301, and a flow area of the defined throttling opening 302 is smaller than or equal to a flow area of the flow dividing channel 201.

The purpose of throttling the fluid flowing to the diversion channel 201 is achieved by the fact that the flow area of the throttling opening 302 is smaller than or equal to the flow area of the diversion channel 201.

Each of the flow dividing channels 201 corresponds to a hollow portion 301, and a flow area of the flow dividing channel 201 is partially overlapped with a flow area of the hollow portion 301 to define a throttle opening 302. The fluid in the main channel 101 flows into the branch channel 201 through the hollow 301 and the orifice 302, and then enters the flow path corresponding to the branch channel 201.

Each of the flow-splitting channels 201 corresponds to one hollow portion 301, but the same hollow portion 301 may correspond to a plurality of flow-splitting channels 201. Wherein the number of the chokes 302 corresponds to the number of the flow dividing channels 201. Optionally, the flow area of the partial chokes 302 is the same. In this way, the flow area of the flow dividing passage 201 corresponding to the flow path having a relatively large difference in heat exchange effect only needs to be adjusted, thereby reducing the complexity of the orifice 30. For example, if there are 4 flow dividing channels and only one of the flow dividing channels needs to be throttled, the throttling element 30 may include two hollow portions 301, where one hollow portion 301 covers 3 flow dividing channels, and the flow area of the throttling opening 302 is equal to the flow area of the flow dividing channel 201. The other hollow part 301 overlaps with a partial flow area of the flow dividing channel, and the flow area of the defined throttling opening 302 is smaller than that of the flow dividing channel 201.

Optionally, the inner side wall of the main channel 101 is provided with a circumferentially surrounding socket 102, the socket 102 being used for mounting the throttle 30. As shown in connection with fig. 1 and 3.

The choke piece 30 is installed through the bearing part 102, so that the stability of the choke piece 30 in the main channel 101 is improved, and the plane of the choke piece 30 and the radial plane of the main channel 101 are ensured to be located on the same plane.

The receiving portion 102 may be formed by an inward protruding structure from the inner sidewall of the main channel 101, or may be formed by bending and extending outward from a set position of the inner sidewall of the main channel 101.

Optionally, the main channel 101 comprises a first side wall 105, a bay 102 and a second side wall 106. The first sidewall 105 encloses a first channel and includes an inlet 103 in communication with the first channel, wherein the inlet 103 is located at a bottom of the sidewall. The receiving portion 102 is formed by bending and extending outward from the top edge of the first sidewall 105. The second sidewall 106 is formed by bending and extending upward from the edge of the receiving portion 102, the second sidewall 106 defines a second channel, the second channel is communicated with the first channel, and includes an outlet 104 opposite to the inlet 103.

The orifice member 30 is positioned on the receiving portion 102, and a circumferential side wall of the orifice member 30 is in contact with an inner side wall of the second passage. Therefore, on one hand, the connection firmness between the throttling element 30 and the body 10 is improved, and on the other hand, the fluid is prevented from flowing into the second channel from the gap between the throttling element 30 and the inner side wall of the second channel as far as possible, so that the throttling effect of the throttling element 30 on the shunting channel 201 is influenced.

The flow divider 20 is disposed in the second channel, and the circumferential side wall of the flow divider 20 contacts with the inner side wall of the second channel, and a sealing ring is disposed between the two to prevent the fluid in the main channel 101 from flowing out from the gap between the two.

Optionally, the inner side wall of the main channel 101 is provided with a first limiting portion 40, and the edge of the throttling element 30 is configured with a groove 303 matched with the first limiting portion 40, wherein the first limiting portion 40 is matched with the groove 303 to limit the throttling element 30 to rotate relative to the main channel 101.

Under the condition of installing the throttling element 30, the groove 303 of the throttling element 30 is aligned to the first limiting part 40 and is matched with the first limiting part 40, so that the throttling element 30 can be prevented from rotating relative to the main channel 101 through the first limiting part 40, and the flow area of the throttling opening 302 defined between the throttling element 30 and the flow dividing element 20 is ensured to be unchanged, so that the heat exchange effect of the heat exchanger is prevented from being influenced.

The first position-limiting portion 40 is located at the receiving portion 102. Alternatively, the first stopper portion 40 is formed from an inwardly protruding configuration of the inner side wall of the second passage. Alternatively, the first stopper portion 40 is formed in a protruding configuration upwardly from the surface of the receiving portion 102.

Alternatively, the first position-limiting portion 40 has an arc-shaped structure, and accordingly, the groove 303 of the throttle 30 has an arc-shaped structure. In practical applications, the first position-limiting portion 40 may also have other structures, and the groove 303 of the throttling element 30 has the same structure as the first position-limiting portion 40.

Optionally, the flow splitter 20 comprises: the orifice plate 202 is provided with a plurality of through holes 203, and the edges of the through holes 203 are bent and extended along a first direction to form a flow distribution channel 201; the edge of the orifice plate 202 is bent and extended along the first direction to form the housing 204, the housing 204 and the orifice plate 202 define an accommodating cavity 205, and a partial area of the hollow portion 301 is communicated with the accommodating cavity 205, so that a part of the fluid flowing out from the hollow portion 301 flows into the accommodating cavity 205, and the impact of the fluid on the throttling element 30 is buffered.

The through holes 203 are uniformly arranged at intervals, the edges of the through holes 203 bend and extend along the first direction to form a shunting channel 201, wherein the shunting channel 201 is located in the main channel 101, and the shunting channel 201 is in contact with the throttling element 30.

The edge of the orifice plate 202 is bent and extended in the first direction to form a housing 204, and the flow divider 20 is connected to the main channel 101 through the housing 204. For example, after the housing 204 of the flow divider 20 is screwed to the inner sidewall of the main channel 101, or the flow dividing channel 201 corresponds to the hollow portion 301 of the throttle 30, the housing 204 of the flow divider is fixed to the main channel 101 by welding, so as to prevent the flow divider 20 from rotating relative to the main channel 101 under the impact of the fluid.

Alternatively, in the case where the orifice plate 202 is disposed horizontally and upward, the bottom surface of the flow dividing channel 201 and the bottom surface of the housing 204 are located on the same plane. In this way, after the flow dividing member 20 and the throttling member 30 are installed, the flow dividing channel 201 and the housing 204 can simultaneously contact with the surface of the throttling member 30, which helps to improve the stability of the liquid distributor during use.

A containing cavity 205 is defined by the shell 204 and the orifice plate 202, and a partial area of the hollow part 301 is communicated with the containing cavity 205; thus, the fluid flowing out of the hollow portion 301 and not the orifice 302 flows into the housing chamber 205, and the impact force of the fluid that cannot flow out through the orifice 302 in the main passage 101 on the orifice 30 can be reduced. The fluid flowing into the accommodating chamber 205 can flow in the accommodating chamber 205.

Optionally, the inner sidewall of the main channel 101 is provided with a second limiting portion 50, and the sidewall of the housing 204 is configured with a limiting groove 206, wherein the second limiting portion 50 cooperates with the limiting groove 206 to limit the flow divider 20 from rotating relative to the main channel 101.

The second limiting portion 50 protrudes from the inner side wall of the main channel 101, and the limiting groove 206 of the housing 204 is a through groove with an open end, so that when the flow distribution member 20 is installed, the flow distribution member 20 can be inserted into and matched with the second limiting portion 50 through the limiting groove 206, and the purpose of limiting the flow distribution member 20 to rotate relative to the main channel 101 is achieved.

Alternatively, when there are a plurality of second position limiting portions 50, the plurality of second position limiting portions 50 are disposed at regular intervals. This helps to force the diverter 20 and the body 10 evenly.

Optionally, the second position-limiting portion 50 has a rectangular structure, and the position-limiting groove 206 also has a rectangular structure. Thus, under the condition that the second limiting part 50 is installed in cooperation with the limiting groove 206, the contact area between the second limiting part 50 and the limiting groove 206 is large, which is beneficial to improving the limiting effect between the shunt member 20 and the body 10.

Optionally, the outer side wall of the main channel 101 is configured with a recess 107, and the recess 107 is used for displaying the corresponding position of the first position-limiting part 40 and/or the second position-limiting part 50. As shown in connection with fig. 2 and 3.
