Distributor, heat exchanger and air conditioner

Technical Field

The invention belongs to the technical field of household electrical equipment, and particularly relates to a distributor, a heat exchanger and an air conditioner.

Background

In the distributor in the prior art, the sizes of all the shunt pipes are the same, and in order to adjust the flow of all the flow paths connected with the distributor, the flow can be adjusted only by adjusting the sizes of all the external pipelines.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art or the related art.

To this end, a first object of the invention is to propose a dispenser.

A second object of the invention is to propose a heat exchanger.

A third object of the present invention is to provide an air conditioner.

To achieve at least one of the above objects, according to a first aspect of the present invention, there is provided a dispenser for an air conditioner, comprising: an inlet pipe; at least one first shunt pipe communicated with the inflow pipe; at least one second shunt pipe communicated with the inflow pipe; wherein, the first shunt pipe and the second shunt pipe have different volumes.

The application provides a distributor for air conditioner, including inlet tube, at least one first shunt tubes and at least one second shunt tubes, wherein, first shunt tubes and second shunt tubes all communicate with the inlet tube. The distributor is arranged in the flow path of the heat exchanger and used for distributing the refrigerant in the flow path of the heat exchanger and adjusting the flow of each flow path. Specifically, the refrigerant flows into the distributor from the inflow pipe and then flows into the first shunt pipe and the second shunt pipe, the first shunt pipe and the second shunt pipe are respectively connected with the external pipelines of the heat exchanger, and the refrigerant flows into the corresponding external pipelines through the first shunt pipe and the second shunt pipe respectively, so that the refrigerant is shunted.

Further, the first shunt pipe and the second shunt pipe have different volumes. The refrigerant enters the flow divider from the inflow pipe and then respectively flows into the first shunt pipe and the second shunt pipe, and then flows into the external pipeline through the first shunt pipe and the second shunt pipe. It is understood that the flow rate of the refrigerant in each external pipe is related to the volume of the first or second branch pipe connected to each external pipe. Specifically, first shunt tubes are the same with the length of second shunt tubes, if the volume of first shunt tubes is less than second shunt tubes, the coolant volume that can flow through first shunt tubes in unit time is less than the coolant volume that can flow through second shunt tubes in unit time, also the flow of first shunt tubes is less than the flow of second shunt tubes, thereby make the flow of the external pipeline of being connected with first shunt tubes be less than the flow of the external pipeline of being connected with second shunt tubes, and then realize the effect of the flow of adjusting each external pipeline through the distributor.

Through set up at least one first shunt tubes and at least one second shunt tubes in the distributor for the refrigerant flows into each shunt tubes when flowing through the distributor, realizes the effect to the refrigerant reposition of redundant personnel. Further, the volume of first shunt tubes and second shunt tubes is set to be different, thereby making first shunt tubes and second shunt tubes have different flow rates, make the refrigerant flow into each external pipeline rather than being connected with the flow rate inflow of difference after passing through first shunt tubes and second shunt tubes, realize the effect of adjusting the flow rate of each external pipeline through the distributor, need not to adjust the flow rate through the external pipeline that sets up multiple specification, can unify the external pipeline that adopts a size and connect in the distributor, thereby it is more easy to make the external pipeline standardized, and the production cost is reduced, and because the external pipeline of unified specification can be adopted, thereby can guarantee the uniformity of the product of same batch, the stability of the product quality of same batch is improved. Furthermore, the external pipeline is standardized, so that the welding position of the external pipeline and the distributor is controllable, and the automatic production of products is facilitated.

The dispenser according to the invention as described above may also have the following additional technical features:

in the above technical solution, further, the ratio of the length of the first pipe section of the first shunt pipe to the length of the second pipe section of the first shunt pipe is a first ratio; the ratio of the length of the first pipe section of the second shunt pipe to the length of the second pipe section of the second shunt pipe is a second ratio; the first shunt pipe and the second shunt pipe are the same in length, and the first ratio is different from the second ratio.

In this technical scheme, first shunt tubes and second shunt tubes are multistage structure, and specifically, first shunt tubes and second shunt tubes all include first pipeline section and second pipeline section. The inner diameters of the first pipe section and the second pipe section of the first shunt pipe are different, and the inner diameters of the first pipe section and the second pipe section of the second shunt pipe are also different. It can be understood that the flow rate of the shunt tube is smaller when the proportion of the smaller inner diameter of the first tube section and the second tube section in the length of the shunt tube is larger, and therefore, the flow rate of the first shunt tube and the second shunt tube can be adjusted by adjusting the length proportion of the first tube section and the second tube section. Specifically, the length ratio of the first pipe section of the first shunt pipe and the length ratio of the second pipe section of the first shunt pipe is defined as a first ratio, the ratio of the length of the first pipe section of the second shunt pipe and the length ratio of the second pipe section of the second shunt pipe is defined as a second ratio, and because the lengths of the first shunt pipe and the second shunt pipe are the same, under the condition that the first ratio and the second ratio are different, the flow rates of the first shunt pipe and the second shunt pipe are also different, so that the refrigerant flow rate can be adjusted through the flow divider.

Specifically, in the case where the inner diameter of the first pipe section of the first shunt pipe is smaller than the inner diameter of the second pipe section of the first shunt pipe, and the inner diameter of the first pipe section of the second shunt pipe is smaller than the inner diameter of the second pipe section of the second shunt pipe, if the first ratio is smaller than the second ratio, the flow rate of the first shunt pipe is greater than the flow rate of the second shunt pipe, and conversely, if the first ratio is greater than the second ratio, the flow rate of the first shunt pipe is less than the flow rate of the second shunt pipe.

Further, because the length of the first shunt pipe is equal to that of the second shunt pipe, the flow rate relationship between the first shunt pipe and the second shunt pipe can be directly determined through the comparison result of the lengths of the pipe section with the smaller inner diameter in the first shunt pipe and the pipe section with the smaller inner diameter in the second shunt pipe. Specifically, taking the case that the inner diameter of the first pipe section of the first shunt pipe is smaller than the inner diameter of the second pipe section of the first shunt pipe, and the inner diameter of the first pipe section of the second shunt pipe is smaller than the inner diameter of the second pipe section of the second shunt pipe as an example, if the length of the first pipe section of the first shunt pipe is smaller than the length of the first pipe section of the second shunt pipe, the flow rate of the first shunt pipe is greater than the flow rate of the second shunt pipe, and conversely, if the length of the first pipe section of the first shunt pipe is greater than the length of the first pipe section of the second shunt pipe, the flow rate of the first shunt pipe is smaller than the flow rate of the second shunt pipe.

The first ratio of the length of the first pipe section of the first shunt pipe and the length of the second pipe section of the first shunt pipe is limited to be different from the second ratio of the length of the first pipe section of the second shunt pipe and the length of the second pipe section of the second shunt pipe, the flow of the first shunt pipe and the flow of the second shunt pipe can be adjusted by adjusting the first ratio and the second ratio, the adjustment of the flow by the distributor is realized, the flow is not required to be adjusted by setting external pipelines of various specifications, the external pipelines of one size can be uniformly connected to the distributor, the external pipelines are more easily standardized, the production cost is reduced, and the external pipelines of uniform specifications can be adopted, so that the consistency of products of the same batch can be ensured, and the stability of the quality of products of the same batch is improved. Furthermore, the external pipeline is standardized, so that the welding position of the external pipeline and the distributor is controllable, and the automatic production of products is facilitated.

In the above technical solution, further, a ratio of a first inner diameter of the first pipe section of the first shunt pipe to a second inner diameter of the second pipe section of the first shunt pipe is a third ratio; the ratio of the third inner diameter of the first pipe section of the second shunt pipe to the fourth inner diameter of the second pipe section of the second shunt pipe is a fourth ratio; the third ratio is different from the fourth ratio.

In the technical scheme, the inner diameters of the first pipe section of the first shunt pipe and the second pipe section of the first shunt pipe are different, and the ratio of the inner diameters of the first pipe section of the first shunt pipe and the second pipe section of the first shunt pipe is defined as a third ratio. The first pipe section of the second shunt pipe and the second pipe section of the second shunt pipe are different in inner diameter, and the ratio of the inner diameters of the second pipe section of the second first shunt pipe and the second pipe section of the first shunt pipe is defined as a fourth ratio.

The first shunt tube and the second shunt tube have the same length, and a case where the first tube section of the first shunt tube has the same length as the first tube section of the second shunt tube, the inner diameter of the first tube section of the first shunt tube is smaller than the inner diameter of the second tube section of the first shunt tube, and the inner diameter of the first tube section of the second shunt tube is smaller than the inner diameter of the second tube section of the second shunt tube will be described as an example. It will be appreciated that in this case the smaller the third ratio, the smaller the flow of the first shunt tube, and likewise the smaller the fourth ratio, the smaller the flow of the second shunt tube. Therefore, the flow rates of the first shunt pipe and the second shunt pipe are adjusted by adjusting the third ratio and the fourth ratio.

The flow of the first shunt pipe and the second shunt pipe can be adjusted by adjusting the third ratio and the fourth ratio, so that the flow can be adjusted by the distributor, the flow can be adjusted without adjusting the flow by setting external pipelines with various specifications, the external pipelines with one size can be uniformly connected to the distributor, the external pipelines are more easily standardized, the production cost is reduced, and the external pipelines with uniform specifications can be adopted, so that the consistency of products in the same batch can be ensured, and the stability of the quality of products in the same batch is improved. Furthermore, the external pipeline is standardized, so that the welding position of the external pipeline and the distributor is controllable, and the automatic production of products is facilitated.

In the above technical solution, further, the first inner diameter is smaller than the second inner diameter; the third inner diameter is smaller than the fourth inner diameter.

In this embodiment, the first inner diameter is smaller than the second inner diameter, and the third inner diameter is smaller than the fourth inner diameter. It will be appreciated that the shunt tube is divided into a plurality of segments having different internal diameters so that the flow through the shunt tube can be regulated by adjusting the length and internal diameter of each segment. Taking the first shunt tube as an example, when the first inner diameter of the first tube section of the first shunt tube is smaller than the second inner diameter of the second tube section of the first shunt tube, the smaller the ratio of the first inner diameter to the second inner diameter, the smaller the flow rate of the first shunt tube.

Through injecing first internal diameter and being less than the second internal diameter, the third internal diameter is less than the fourth internal diameter to set up first shunt tubes and second shunt tubes into the structure of the pipeline section including different internal diameters, and then the flow of this shunt tubes is adjusted to the ratio of the internal diameter of each pipeline section of accessible adjustment, realize through the regulation of distributor to the flow, need not to adjust the flow through the external pipeline that sets up multiple specification, can unify the external pipeline that adopts a size and connect in the distributor, realize external pipeline's standardization.

In the above technical solution, further, the first shunt pipe and the second shunt pipe have the same outer diameter.

In the technical scheme, the outer diameters of the first shunt pipe and the second shunt pipe are the same, so that at least one first shunt pipe and at least one second shunt pipe can be arranged in the distributor in a unified shape and size, the first shunt pipe and the second shunt pipe are more easily connected with an external pipeline of the same specification, the weight of the first shunt pipe and the weight of the second shunt pipe of the same outer diameter are close to each other, and the weight of each position of the distributor is more balanced.

The outer diameters of the first shunt pipe and the second shunt pipe are set to be the same, so that the first shunt pipe and the second shunt pipe are easier to be connected with an external pipeline of the same specification, and the standardization of the external pipeline of the distributor is further realized.

In the above technical solution, further, the inflow pipe includes: the first wall surface comprises a first side and a second side departing from the first side; the first shunt pipe and the second shunt pipe are arranged on the first side; the flow guide part is arranged on the second side; the flow guide part and the inner wall of the flow inlet pipe form a flow dividing cavity, and the flow dividing cavity is communicated with the first flow dividing pipe and the second flow dividing pipe.

In this technical scheme, the inlet flow pipe includes first wall, and first wall includes first side and the second side that deviates from first side, and first shunt tubes and second shunt tubes all set up in first side. The second side of the first wall faces the inner cavity of the inflow pipe, and a flow guide part is further arranged in the inflow pipe and arranged on the second side of the first wall, namely the flow guide part is arranged in the inner cavity of the inflow pipe.

A certain distance is reserved between the flow guide part and the inner wall of the flow inlet pipe, so that the flow guide part and the inner wall of the flow inlet pipe form a flow dividing cavity, and the flow dividing cavity is communicated with the first flow dividing pipe and the second flow dividing pipe. After entering the inflow pipe, the refrigerant is shunted by the diversion part, enters the shunt cavity between the diversion part and the inner wall of the inflow pipe, and then enters the first shunt pipe and the second shunt pipe through the shunt cavity.

The flow guide part is arranged in the flow inlet pipe, so that the flow guide effect on the refrigerant is achieved, and the refrigerant is uniformly guided into the first flow dividing pipe and the second flow dividing pipe.

In the above technical solution, further, the flow guide portion is a conical protrusion, and a sectional area of an end of the flow guide portion departing from the first wall surface is smaller than a sectional area of an end of the flow guide portion facing the first wall surface.

In this technical scheme, water conservancy diversion portion is the protruding structure of toper, and specifically, the cross-sectional area of the one end that water conservancy diversion portion deviates from the first wall is less than the cross-sectional area of the one end of water conservancy diversion portion towards the first wall. The flow guide part is arranged on the inner wall of the flow guide part, the flow guide part is arranged on the outer wall of the flow guide part, and the inner wall of the flow guide part is provided with a plurality of holes.

Through setting up the water conservancy diversion portion into the bellied structure of toper to set up the sectional area that water conservancy diversion portion deviates from first wall one end into being less than the sectional area of water conservancy diversion portion towards first wall one end, thereby make the less one end of sectional area of the bellied water conservancy diversion portion of toper towards the inflow direction of refrigerant, thereby reduce the hindrance of water conservancy diversion portion to the refrigerant, reduce the influence of water conservancy diversion portion to the refrigerant velocity of flow, and can make the refrigerant flow along the wall of water conservancy diversion portion more easily, thereby realize the water conservancy diversion function to the refrigerant.

In the above technical solution, further, the inflow pipe includes: a flow inlet cavity; the transition cavity is arranged between the flow inlet cavity and the first wall surface, and the flow guide part is arranged in the transition cavity.

In the technical scheme, the inflow pipe comprises an inflow cavity and a transition cavity, wherein the transition cavity is arranged between the inflow cavity and the first wall surface. After entering the distributor, the refrigerant firstly flows into the inflow cavity, and the refrigerant flowing through the inflow cavity enters the transition cavity. The diversion part is arranged in the transition cavity, the refrigerant is in contact with the diversion part after entering the transition cavity, and the diversion part diverts the refrigerant and conducts diversion on the refrigerant, so that the refrigerant can flow into the first shunt pipe and the second shunt pipe through different flow paths.

It can be understood that, if the refrigerant flows into the distributor, because of the change of the inner diameter of the pipeline, the flow velocity of the refrigerant can be changed to a certain extent, if the refrigerant is immediately divided and guided, the refrigerant is easy to be unstable, in order to keep the refrigerant in a stable flowing state, after the refrigerant flows into the distributor, the refrigerant is firstly transited through the inflow cavity, after the refrigerant flows in the distributor in a stable state, the refrigerant enters the transition cavity, and the refrigerant is guided through the guide part in the transition cavity, so that the guide of the refrigerant is realized, and the refrigerant can be kept in a stable flowing state.

The inflow pipe is divided into the inflow cavity and the transition cavity, the refrigerant can be stably transited through the inflow cavity to keep the stable flowing state of the refrigerant, and then the refrigerant is guided by the guide part in the transition cavity, so that the refrigerant is guided, and the refrigerant can be kept in the stable flowing state.

In the above technical solution, further, the cross-sectional area of the transition cavity gradually increases in a direction toward the first wall surface.

In this solution, the cross-sectional area of the transition chamber gradually increases in a direction toward the first wall surface. It can be understood that, because the water conservancy diversion portion sets up in the transition chamber, and the water conservancy diversion portion is whole to be the toper, and the water conservancy diversion portion is along the direction sectional area crescent towards first wall, if the size of transition chamber in each position keeps unchangeable, then because the sectional area size of water conservancy diversion portion changes, the sectional area of the reposition of redundant personnel chamber between the wall of water conservancy diversion portion and transition chamber can reduce gradually, and this can produce the influence to the velocity of flow of refrigerant, leads to the refrigerant to appear unstable state. In order to reduce the influence of the flow guide part on the flow velocity of the refrigerant, the transitional cavity is in a variable-section structure, specifically, the sectional area of the transitional cavity towards the direction of the first wall surface is gradually increased, so that the sectional area of the flow dividing cavity is approximately kept unchanged, the influence on the flow velocity of the refrigerant is reduced, and the refrigerant is kept in a stable flowing state.

The sectional area of the transition cavity towards the first wall surface is gradually increased, so that the sectional area of the flow dividing cavity is approximately kept unchanged, the influence on the flow velocity of the refrigerant is reduced, and the refrigerant is kept in a stable flowing state.

In the above technical solution, further, a sectional area of an end of the transition cavity facing the first wall surface is larger than a sectional area of any position of the flow inlet cavity.

In the technical scheme, the sectional area of one end, facing the first wall surface, of the transition cavity is larger than that of any position of the flow inlet cavity. Specifically, the cross-sectional area of the transition cavity close to the side of the flow inlet cavity is the same as that of the flow inlet cavity, so that the refrigerant is stable when flowing into the transition cavity from the flow inlet cavity. In order to keep the sectional area of the diversion cavity between the cavity wall of the transition cavity and the diversion part approximately constant, the sectional area of the transition cavity is gradually increased towards the first wall surface, namely, the sectional area of one end of the transition cavity towards the first wall surface is the maximum sectional area of the transition cavity, so that the sectional area of one end of the transition cavity towards the first wall surface is larger than the sectional area of any position of the inflow cavity.

The sectional area of one end of the transition cavity facing the first wall surface is larger than that of any position of the flow inlet cavity, so that the sectional area of the flow dividing cavity between the cavity wall of the transition cavity and the flow guide part can be kept unchanged approximately, and the stable flowing state of the refrigerant in the flow dividing cavity is guaranteed.

In the above technical solution, further, the distributor further includes a plurality of connecting pipes for connecting external pipes; the plurality of connecting pipes are respectively arranged on the at least one first shunt pipe and the at least one second shunt pipe.

In the technical scheme, the distributor is also provided with a plurality of connecting pipes, and the connecting pipes are used for connecting external pipelines. The plurality of connecting pipes are respectively arranged on at least one first shunt pipe and at least one second shunt pipe, namely each first shunt pipe and each second shunt pipe are provided with one connecting pipe. The external pipelines are connected with the first shunt pipe and the second shunt pipe through connecting pipes, and then the refrigerant can flow into each external pipeline through the distributor.

The connecting pipes are arranged in the first shunt pipe and the second shunt pipe, so that the external pipelines can be connected with the first shunt pipe and the second shunt pipe through the connecting pipes, and then the refrigerant can flow into each external pipeline through the distributor. The connecting pipes of the same specification are arranged in the first shunt pipe and the second shunt pipe, so that the first shunt pipe and the second shunt pipe of different sizes can be connected with the external pipeline of the same specification.

In the above technical solution, further, the inner diameter of the connecting pipe is larger than the inner diameter of any position of the first shunt pipe and the second shunt pipe; the outer diameter of the connecting pipe is larger than the outer diameter of the first shunt pipe and the outer diameter of the second shunt pipe.

In the technical scheme, the size of the connecting pipe is limited in order to facilitate the connection of the external pipeline to the connecting pipe. Specifically, the inner diameter of the connecting pipe is larger than the inner diameter of any position of the first shunt pipe and the second shunt pipe; the outer diameter of the connecting pipe is larger than the outer diameter of the first shunt pipe and the outer diameter of the second shunt pipe. It can be understood that, under the condition that the inner diameter of the connecting pipe is larger than the inner diameter of any position of the first shunt pipe and the second shunt pipe, the external pipeline can be inserted into the connecting pipe, and at the root of the connecting pipe, the part smaller than the inner diameter of the connecting pipe can automatically form a limiting wall surface to limit the external pipeline so as to prevent the external pipeline from continuously extending into the first shunt pipe or the second shunt pipe.

The inner diameter of the connecting pipe is larger than that of any position of the first shunt pipe and the second shunt pipe; the outer diameter of the connecting pipe is larger than the outer diameter of the first shunt pipe and the outer diameter of the second shunt pipe, so that the external pipeline can be limited when the external pipeline is inserted into the connecting pipe, and the external pipeline is conveniently connected with the distributor.

In the above technical solution, further, at least one first shunt pipe and at least one second shunt pipe are disposed on a side close to an outer edge of the first wall surface.

In this technical scheme, at least one first shunt canalization pipe and at least one second shunt canalization pipe are located and are close to one side of first wall outward flange, promptly, first shunt canalization pipe and second shunt canalization pipe all distribute along the outward flange of first wall to make first shunt canalization pipe and second shunt canalization pipe be linked together with the reposition of redundant personnel chamber.

The first flow dividing pipe and the second flow dividing pipe can be communicated with the flow dividing cavity by arranging the first flow dividing pipe and the second flow dividing pipe on one side close to the outer edge of the first wall surface, and the smooth flow of the refrigerant is realized.

The second aspect of the invention also proposes a heat exchanger comprising the distributor proposed by the first aspect of the invention.

The heat exchanger provided by the second aspect of the present invention has all the advantages of the distributor, because the distributor provided by the first aspect of the present invention is included.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

A distributor 100, a heat exchanger, and an air conditioner provided according to some embodiments of the present invention are described below with reference to fig. 1 to 6.

The first embodiment is as follows:

referring to fig. 1 and 4, an embodiment of a first aspect of the present invention provides a dispenser 100 for an air conditioner, including: an inlet pipe 110; at least one first shunt tube 120 in communication with the inflow tube 110; at least one second shunt tube 130 in communication with the inflow tube 110; wherein, the first shunt pipe 120 and the second shunt pipe 130 have different volumes.

The present application provides a distributor 100 for an air conditioner, comprising an inlet pipe 110, at least one first shunt pipe 120 and at least one second shunt pipe 130, wherein the first shunt pipe 120 and the second shunt pipe 130 are both communicated with the inlet pipe 110. The distributor 100 is disposed in the flow path of the heat exchanger, and is used for distributing the refrigerant in the flow path of the heat exchanger and adjusting the flow rate of each flow path. Specifically, the refrigerant flows into the distributor 100 from the inlet pipe 110, and then flows into the first shunt pipe 120 and the second shunt pipe 130, the first shunt pipe 120 and the second shunt pipe 130 are respectively connected to external pipelines of the heat exchanger, and the refrigerant flows into the corresponding external pipelines through the first shunt pipe 120 and the second shunt pipe 130, so that the refrigerant is shunted.

Further, the first shunt tube 120 and the second shunt tube 130 have different volumes. The refrigerant enters the flow divider from the inlet pipe 110, then flows into the first and

second branch pipes

120 and 130, and then flows into the external pipeline through the first and

second branch pipes

120 and 130. It is understood that the flow rate of the refrigerant in each external pipe is related to the volume of the first or

second branch pipe

120 or 130 connected to each external pipe. Specifically, the first shunt tube 120 and the second shunt tube 130 have the same length, if the volume of the first shunt tube 120 is smaller than that of the second shunt tube 130, the amount of refrigerant flowing through the first shunt tube 120 in unit time is smaller than that flowing through the second shunt tube 130 in unit time, that is, the flow rate of the first shunt tube 120 is smaller than that of the second shunt tube 130, so that the flow rate of the external pipeline connected to the first shunt tube 120 is smaller than that of the external pipeline connected to the second shunt tube 130, and the effect of adjusting the flow rate of each external pipeline through the distributor 100 is achieved.

The distributor 100 is provided with at least one first shunt pipe 120 and at least one second shunt pipe 130, so that the refrigerant flows into each shunt pipe when flowing through the distributor 100, and the refrigerant is shunted. Further, the volumes of the first shunt tube 120 and the second shunt tube 130 are set to be different, so that the first shunt tube 120 and the second shunt tube 130 have different flow rates, the refrigerant flows into each external pipeline connected with the refrigerant at different flow rates after passing through the first shunt tube 120 and the second shunt tube 130, the effect of adjusting the flow rate of each external pipeline through the distributor 100 is realized, the flow rate is not required to be adjusted through the external pipelines with various specifications, the external pipelines with one size can be uniformly connected to the distributor 100, the external pipelines are more easily standardized, the production cost is reduced, and the external pipelines with uniform specifications can be adopted, so that the consistency of products in the same batch can be ensured, and the stability of the quality of products in the same batch is improved. Further, the external pipeline is standardized, so that the welding position of the external pipeline and the distributor 100 is controllable, and the automatic production of products is facilitated.

Example two:

in a specific embodiment based on the first embodiment, as shown in fig. 2, 3 and 5, the ratio of the length of the first pipe section of the first shunt pipe 120 to the length of the second pipe section of the first shunt pipe 120 is a first ratio; the ratio of the length of the first pipe section of the second shunt pipe 130 to the length of the second pipe section of the second shunt pipe 130 is a second ratio; the first shunt tube 120 and the second shunt tube 130 have the same length, and the first ratio is different from the second ratio.

In this embodiment, the first shunt tube 120 and the second shunt tube 130 are each a multi-segment structure, and specifically, the first shunt tube 120 and the second shunt tube 130 each include a first tube segment and a second tube segment. The first and second sections of the first shunt tube 120 have different inner diameters, and the first and second sections of the second shunt tube 130 have different inner diameters. It can be understood that the flow rate of the shunt tube is smaller when the ratio of the length of the shunt tube to the smaller inner diameter of the first tube section and the second tube section is larger, and thus, the flow rate of the first shunt tube 120 and the second shunt tube 130 can be adjusted by adjusting the length ratio of the first tube section and the second tube section. Specifically, the ratio of the length of the first pipe section of the first shunt pipe 120 to the length of the second pipe section of the first shunt pipe 120 is defined as a first ratio, and the ratio of the length of the first pipe section of the second shunt pipe 130 to the length of the second pipe section of the second shunt pipe 130 is defined as a second ratio, and because the lengths of the first shunt pipe 120 and the second shunt pipe 130 are the same, and under the condition that the first ratio is different from the second ratio, the flow rates of the first shunt pipe 120 and the second shunt pipe 130 are also different, so that the refrigerant flow rate can be adjusted through the flow divider.

Specifically, in the case where the inner diameter of the first pipe section of the first shunt pipe 120 is smaller than the inner diameter of the second pipe section of the first shunt pipe 120, and the inner diameter of the first pipe section of the second shunt pipe 130 is smaller than the inner diameter of the second pipe section of the second shunt pipe 130, if the first ratio is smaller than the second ratio, the flow rate of the first shunt pipe 120 is greater than the flow rate of the second shunt pipe 130, and, conversely, if the first ratio is greater than the second ratio, the flow rate of the first shunt pipe 120 is smaller than the flow rate of the second shunt pipe 130.

Further, since the length of the first shunt tube 120 is equal to the length of the second shunt tube 130, the flow rate relationship between the first shunt tube 120 and the second shunt tube 130 can be directly determined by comparing the lengths of the tube sections with smaller inner diameters in the first shunt tube 120 and the second shunt tube 130. Specifically, taking the case that the inner diameter of the first pipe section of the first shunt pipe 120 is smaller than the inner diameter of the second pipe section of the first shunt pipe 120, and the inner diameter of the first pipe section of the second shunt pipe 130 is smaller than the inner diameter of the second pipe section of the second shunt pipe 130 as an example, if the length of the first pipe section of the first shunt pipe 120 is smaller than the length of the first pipe section of the second shunt pipe 130, the flow rate of the first shunt pipe 120 is greater than the flow rate of the second shunt pipe 130, and conversely, if the length of the first pipe section of the first shunt pipe 120 is greater than the length of the first pipe section of the second shunt pipe 130, the flow rate of the first shunt pipe 120 is smaller than the flow rate of the second shunt pipe 130.

The first ratio of the length of the first pipe section of the first shunt pipe 120 to the length of the second pipe section of the first shunt pipe 120 to the second ratio of the length of the first pipe section of the second shunt pipe 130 to the length of the second pipe section of the second shunt pipe 130 is different, the flow of the first shunt pipe 120 and the flow of the second shunt pipe 130 can be adjusted by adjusting the first ratio and the second ratio, the adjustment of the flow of the distributor 100 is realized, the flow is not required to be adjusted by setting external pipelines with various specifications, the external pipelines with one size can be uniformly connected to the distributor 100, the external pipelines are more easily standardized, the production cost is reduced, and the external pipelines with uniform specifications can be adopted, so that the consistency of products in the same batch can be ensured, and the stability of the quality of products in the same batch is improved. Further, the external pipeline is standardized, so that the welding position of the external pipeline and the distributor 100 is controllable, and the automatic production of products is facilitated.

Example three:

in a specific embodiment based on any of the above embodiments, as shown in fig. 2, 3 and 5, a ratio of the first inner diameter of the first pipe section of the first shunt pipe 120 to the second inner diameter of the second pipe section of the first shunt pipe 120 is a third ratio; the ratio of the third inner diameter of the first pipe section of the second shunt pipe 130 to the fourth inner diameter of the second pipe section of the second shunt pipe 130 is a fourth ratio; the third ratio is different from the fourth ratio.

In this embodiment, the first pipe section of the first shunt pipe 120 and the second pipe section of the first shunt pipe 120 have different inside diameters, and the ratio of the inside diameters of the first pipe section of the first shunt pipe 120 and the second pipe section of the first shunt pipe 120 is defined as a third ratio. The first pipe section of the second shunt pipe 130 and the second pipe section of the second shunt pipe 130 have different inside diameters, defining the ratio of the inside diameters of the second pipe section of the second first shunt pipe 120 and the second pipe section of the first shunt pipe 120 as a fourth ratio.

The first shunt tube 120 and the second shunt tube 130 have the same length, and the case where the first pipe section length of the first shunt tube 120 is equal to the first pipe section length of the second shunt tube 130, the inner diameter of the first pipe section of the first shunt tube 120 is smaller than the inner diameter of the second pipe section of the first shunt tube 120, and the inner diameter of the first pipe section of the second shunt tube 130 is smaller than the inner diameter of the second pipe section of the second shunt tube 130 will be described as an example. It will be appreciated that in this case, the smaller the third ratio, the smaller the flow rate of the first shunt tube 120, and likewise, the smaller the fourth ratio, the smaller the flow rate of the second shunt tube 130. Therefore, the flow rates of the first shunt tube 120 and the second shunt tube 130 are adjusted by adjusting the third ratio and the fourth ratio.

The third ratio of the first inner diameter of the first pipe section of the first shunt pipe 120 to the second inner diameter of the second pipe section of the first shunt pipe 120 to the fourth ratio of the third inner diameter of the first pipe section of the second shunt pipe 130 to the fourth inner diameter of the second pipe section of the second shunt pipe 130 is different, the flow of the first shunt pipe 120 and the flow of the second shunt pipe 130 can be adjusted by adjusting the third ratio and the fourth ratio, the adjustment of the flow of the distributor 100 is realized, the flow is not required to be adjusted by setting external pipelines with various specifications, the external pipelines with one size can be uniformly connected to the distributor 100, the external pipelines are easier to standardize, the production cost is reduced, and the external pipelines with uniform specifications can be adopted, so that the consistency of products in the same batch can be ensured, and the stability of the quality of products in the same batch is improved. Further, the external pipeline is standardized, so that the welding position of the external pipeline and the distributor 100 is controllable, and the automatic production of products is facilitated.

Example four:

in a specific embodiment based on any of the above embodiments, as shown in fig. 2, 3 and 5, the first inner diameter is smaller than the second inner diameter; the third inner diameter is smaller than the fourth inner diameter.

In this embodiment, the first inner diameter is less than the second inner diameter and the third inner diameter is less than the fourth inner diameter. It will be appreciated that the shunt tube is divided into a plurality of segments having different internal diameters so that the flow through the shunt tube can be regulated by adjusting the length and internal diameter of each segment. Taking the first shunt tube 120 as an example, in the case that the first inner diameter of the first pipe section of the first shunt tube 120 is smaller than the second inner diameter of the second pipe section of the first shunt tube 120, the smaller the ratio of the first inner diameter to the second inner diameter, the smaller the flow rate of the first shunt tube 120.

Through injecing first internal diameter and being less than the second internal diameter, the third internal diameter is less than the fourth internal diameter to set up first shunt tubes 120 and second shunt tubes 130 into the structure of the pipeline section including different internal diameters, and then the flow of this shunt tubes is adjusted to the ratio of the internal diameter of accessible adjustment each pipeline section, realize through distributor 100 to the regulation of flow, need not to adjust the flow through the external pipeline that sets up multiple specification, can unify the external pipeline that adopts a size and connect in distributor 100, realize external pipeline's standardization.

Example five:

in a specific embodiment based on any of the above embodiments, as shown in fig. 1 and 4, the first shunt tube 120 and the second shunt tube 130 have the same outer diameter.

In this embodiment, the first shunt tubes 120 and the second shunt tubes 130 have the same outer diameter, so that the at least one first shunt tube 120 and the at least one second shunt tube 130 can be arranged in the distributor 100 with uniform external dimensions, the first shunt tube 120 and the second shunt tube 130 can be more easily connected with external pipelines of the same specification, and the weights of the first shunt tube 120 and the second shunt tube 130 with the same outer diameter dimension are close to each other, so that the weights of all positions of the distributor 100 are more balanced.

By setting the outer diameters of the first shunt tube 120 and the second shunt tube 130 to be the same, the first shunt tube 120 and the second shunt tube 130 can be more easily connected with external pipelines of the same specification, thereby realizing standardization of external pipelines of the distributor 100.

Example six:

in a specific embodiment based on any of the above embodiments, as shown in fig. 3 and 6, the inlet pipe 110 includes: a first wall 111, the first wall 111 comprising a first side and a second side facing away from the first side; the first shunt tube 120 and the second shunt tube 130 are arranged on the first side; a flow guide part 112 arranged on the second side; the guide portion 112 and the inner wall of the inlet pipe 110 form a flow dividing chamber 113, and the flow dividing chamber 113 is communicated with the first flow dividing pipe 120 and the second flow dividing pipe 130.

In this embodiment, the inlet pipe 110 comprises a first wall 111, the first wall 111 comprises a first side and a second side facing away from the first side, and the first shunt pipe 120 and the second shunt pipe 130 are both arranged on the first side. The second side of the first wall surface 111 faces the inner cavity of the inlet pipe 110, a flow guiding portion 112 is further disposed in the inlet pipe 110, the flow guiding portion 112 is disposed on the second side of the first wall surface 111, that is, the flow guiding portion 112 is disposed in the inner cavity of the inlet pipe 110.

A certain distance is left between the flow guiding part 112 and the inner wall of the inlet pipe 110, so that the flow guiding part 112 and the inner wall of the inlet pipe 110 form a flow dividing cavity 113, and the flow dividing cavity 113 is communicated with the first flow dividing pipe 120 and the second flow dividing pipe 130. After entering the inlet pipe 110, the refrigerant is split by the flow guide part 112, enters the split cavity 113 between the flow guide part 112 and the inner wall of the inlet pipe 110, and enters the first split pipe 120 and the second split pipe 130 through the split cavity 113.

The flow guide part 112 is provided in the inlet pipe 110 to guide the refrigerant, and the refrigerant is uniformly guided to the first and

second branch pipes

120 and 130.

Example seven:

in a specific embodiment based on any of the above embodiments, as shown in fig. 3 and fig. 6, the flow guiding portion 112 is a conical protrusion, and a cross-sectional area of an end of the flow guiding portion 112 facing away from the first wall 111 is smaller than a cross-sectional area of an end of the flow guiding portion 112 facing toward the first wall 111.

In this embodiment, the flow guide portion 112 is a conical protrusion structure, and specifically, a cross-sectional area of an end of the flow guide portion 112 facing away from the first wall surface 111 is smaller than a cross-sectional area of an end of the flow guide portion 112 facing toward the first wall surface 111. It can be understood that, when the refrigerant flows through the flow guide portion 112, the refrigerant flows along the wall surface of the flow guide portion 112, the flow guide portion 112 is configured as a conical protrusion, and the end of the conical protrusion with the smaller cross-sectional area faces the inflow direction of the refrigerant, so that the obstruction of the flow guide portion 112 to the refrigerant can be reduced, the influence of the flow guide portion 112 on the flow velocity of the refrigerant can be reduced, and the refrigerant can more easily flow along the wall surface of the flow guide portion 112, thereby realizing the flow guide function of the refrigerant.

The flow guide part 112 is set to be of a conical convex structure, the sectional area of one end, away from the first wall surface 111, of the flow guide part 112 is set to be smaller than the sectional area of one end, facing the first wall surface 111, of the flow guide part 112, so that the end, with the smaller sectional area, of the conical convex flow guide part 112 faces the inflow direction of the refrigerant, the obstruction of the flow guide part 112 to the refrigerant is reduced, the influence of the flow guide part 112 on the flow velocity of the refrigerant is reduced, the refrigerant can flow along the wall surface of the flow guide part 112 more easily, and the flow guide function of the refrigerant is achieved.

Example eight:

in a specific embodiment based on any of the above embodiments, as shown in fig. 3 and 6, the inlet pipe 110 includes: an inlet chamber 114; and the transition cavity 115 is arranged between the flow inlet cavity 114 and the first wall surface 111, and the flow guide part 112 is arranged in the transition cavity 115.

In this embodiment, the inlet pipe 110 comprises an inlet chamber 114 and a transition chamber 115, wherein the transition chamber 115 is provided between the inlet chamber 114 and the first wall 111. After entering the distributor 100, the refrigerant first flows into the inlet chamber 114, and the refrigerant flowing through the inlet chamber 114 enters the transition chamber 115. The diversion portion 112 is disposed in the transition cavity 115, the refrigerant enters the transition cavity 115 and then contacts the diversion portion 112, and the diversion portion 112 diverts the refrigerant and diverts the refrigerant, so that the refrigerant flows into the first diversion pipe 120 and the second diversion pipe 130 through different flow paths.

It can be understood that, if the refrigerant flows into the distributor 100, the flow rate of the refrigerant may change due to the change of the inner diameter of the pipeline, if the refrigerant is immediately split and guided, an unstable state of the refrigerant is easily caused, in order to keep the refrigerant in a stable flowing state, after the refrigerant flows into the distributor 100, the refrigerant is firstly transited through the inflow cavity 114, and after the refrigerant flows in the distributor 100 in a stable state, the refrigerant enters the transition cavity 115, and the refrigerant is guided by the guide portion 112 in the transition cavity 115, so that the refrigerant is guided and can be kept in a stable flowing state.

By dividing the inflow pipe 110 into the inflow cavity 114 and the transition cavity 115, the refrigerant can be stably transited through the inflow cavity 114 to maintain a stable flowing state of the refrigerant, and then the refrigerant is guided by the guide portion 112 in the transition cavity 115, so that the refrigerant is guided and can be maintained in a stable flowing state.

Example nine:

in a specific embodiment based on any of the above embodiments, as shown in fig. 3 and 6, the cross-sectional area of the transition cavity 115 is gradually increased toward the first wall 111.

In this embodiment, the transition chamber 115 has a gradually increasing cross-sectional area in a direction towards the first wall 111. It can be understood that, since the flow guide portion 112 is disposed in the transition cavity 115, and the flow guide portion 112 is tapered as a whole, the cross-sectional area of the flow guide portion 112 gradually increases along a direction toward the first wall surface 111, and if the size of the transition cavity 115 at each position is kept unchanged, the cross-sectional area of the flow dividing cavity 113 between the flow guide portion 112 and the wall surface of the transition cavity 115 gradually decreases due to the change of the cross-sectional area of the flow guide portion 112, which may affect the flow velocity of the refrigerant, resulting in an unstable state of the refrigerant. In order to reduce the influence of the flow guide part 112 on the flow velocity of the refrigerant, the transition chamber 115 has a variable cross-section structure, specifically, the cross-sectional area of the transition chamber 115 in the direction toward the first wall surface 111 is gradually increased, so that the cross-sectional area of the flow dividing chamber 113 is substantially kept constant, the influence on the flow velocity of the refrigerant is reduced, and the refrigerant is kept in a stable flowing state.

By gradually increasing the cross-sectional area of the transition chamber 115 toward the first wall surface 111, the cross-sectional area of the branch chamber 113 is substantially maintained, and the influence on the flow velocity of the refrigerant is reduced, thereby maintaining a stable flow state of the refrigerant.

Further, the cross-sectional area of the transition chamber 115 at the end facing the first wall 111 is larger than the cross-sectional area of the inlet chamber 114 at any location.

In this embodiment, the cross-sectional area of the transition chamber 115 at the end facing the first wall 111 is greater than the cross-sectional area of the inlet chamber 114 at any location. Specifically, the cross-sectional area of the transition chamber 115 near the inlet chamber 114 is the same as the cross-sectional area of the inlet chamber 114, so that the refrigerant is stable when flowing from the inlet chamber 114 into the transition chamber 115. In order to keep the sectional area of the flow dividing chamber 113 between the wall of the transition chamber 115 and the flow guide part 112 substantially constant, the transition chamber 115 is configured to gradually increase in size in the sectional area toward the first wall surface 111, that is, the sectional area of one end of the transition chamber 115 toward the first wall surface 111 is the maximum sectional area of the transition chamber 115, and therefore, the sectional area of one end of the transition chamber 115 toward the first wall surface 111 is larger than the sectional area of any position of the flow inlet chamber 114.

By making the cross-sectional area of the end of the transition chamber 115 facing the first wall surface 111 larger than the cross-sectional area of any position of the inlet chamber 114, the cross-sectional area of the branch chamber 113 between the wall surface of the transition chamber 115 and the flow guide portion 112 can be kept substantially constant, thereby ensuring that the refrigerant can be kept in a stable flowing state in the branch chamber 113.

Example ten:

in a specific embodiment based on any of the above embodiments, as shown in fig. 1, 3 and 5, the distributor 100 further includes a plurality of connecting pipes 140 for connecting external pipes; the plurality of connection pipes 140 are respectively provided to the at least one first shunt pipe 120 and the at least one second shunt pipe 130.

In this embodiment, a plurality of connection pipes 140 are further provided in the dispenser 100, and the connection pipes 140 are used to connect external pipes. Wherein, a plurality of connecting pipes 140 are respectively provided at least one first shunt pipe 120 and at least one second shunt pipe 130, that is, each first shunt pipe 120 and each second shunt pipe 130 are provided with one connecting pipe 140. The external pipes are connected to the first and

second branch pipes

120 and 130 through a connection pipe 140, so that the refrigerant can flow into each external pipe through the distributor 100.

By providing the connection pipe 140 in the first and

second branch pipes

120 and 130, the external pipe may be connected to the first and

second branch pipes

120 and 130 through the connection pipe 140, and the refrigerant may flow into each external pipe through the distributor 100. The first shunt pipe 120 and the second shunt pipe 130 having different sizes may be connected to the external pipes having the same size by providing the connection pipe 140 having the same size in the first shunt pipe 120 and the second shunt pipe 130.

Further, the inner diameter of the connection pipe 140 is larger than the inner diameter of any one of the first shunt pipe 120 and the second shunt pipe 130; the connection pipe 140 has an outer diameter greater than that of the first shunt pipe 120 and that of the second shunt pipe 130.

In this embodiment, in order to facilitate the connection of the external line to the connection pipe 140, the size of the connection pipe 140 is limited. Specifically, the inner diameter of the connection pipe 140 is larger than the inner diameter of any one of the first shunt pipe 120 and the second shunt pipe 130; the connection pipe 140 has an outer diameter greater than that of the first shunt pipe 120 and that of the second shunt pipe 130. It can be understood that, under the condition that the inner diameter of the connecting pipe 140 is larger than the inner diameter of any position of the first shunt pipe 120 and the second shunt pipe 130, the external pipe can be inserted into the connecting pipe 140, and at the root of the connecting pipe 140, the part smaller than the inner diameter of the connecting pipe 140 automatically forms a limiting wall surface to limit the external pipe, so as to prevent the external pipe from continuously extending into the first shunt pipe 120 or the second shunt pipe 130.

By making the inner diameter of the connection pipe 140 larger than the inner diameter of any one of the first and

second shunt pipes

120 and 130; the outer diameter of the connection pipe 140 is greater than the outer diameters of the first shunt pipe 120 and the second shunt pipe 130, so that the external pipe can be limited when inserted into the connection pipe 140, and the connection between the external pipe and the distributor 100 is facilitated.
