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: a flow inlet pipe; at least one first shunt tube in communication with the inlet tube; at least one second shunt tube in communication with the inlet tube; wherein the first shunt tube and the second shunt tube have different volumes.
The distributor is used for an air conditioner and comprises an inflow pipe, at least one first shunt pipe and at least one second shunt pipe, wherein the first shunt pipe and the second shunt pipe are communicated with the inflow pipe. 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 regulating the flow rate of each flow path. Specifically, the refrigerant flows into the distributor from the inflow pipe, 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 pipeline of the heat exchanger, and the refrigerant flows into the external pipeline corresponding to the first shunt pipe and the second shunt pipe respectively through the first shunt pipe and the second shunt pipe, so that the flow distribution of the refrigerant is realized.
Further, the first shunt tube and the second shunt tube have different volumes. The refrigerant flows into the first shunt tube and the second shunt tube respectively after entering the shunt from the inflow tube, and flows into the external pipeline through the first shunt tube and the second shunt tube. It will be appreciated that the flow rate of the refrigerant in each external line is related to the volume of the first shunt tube or the second shunt tube connected to each external line. Specifically, if the first shunt tube has the same length as the second shunt tube, the volume of the first shunt tube is smaller than that of the second shunt tube, and the refrigerant quantity capable of flowing through the first shunt tube in unit time is smaller than that capable of flowing through the second shunt tube in unit time, that is, the flow of the first shunt tube is smaller than that of the second shunt tube, so that the flow of an external pipeline connected with the first shunt tube is smaller than that of an external pipeline connected with the second shunt tube, and the effect of adjusting the flow of each external pipeline through the distributor is achieved.
By arranging at least one first shunt tube and at least one second shunt tube in the distributor, the refrigerant flows into each shunt tube when flowing through the distributor, and the effect of shunting the refrigerant is realized. Further, the volumes of the first shunt pipe and the second shunt pipe are set to be different, so that the first shunt pipe and the second shunt pipe have different flow, refrigerant flows into all external pipelines connected with the first shunt pipe and the second shunt pipe at different flow after passing through the first shunt pipe and the second shunt pipe, the effect of adjusting the flow of all external pipelines through the distributor is achieved, the flow is not required to be adjusted through the external pipelines with various specifications, the external pipelines with one size can be uniformly adopted to be connected with the distributor, the external pipelines are more easily standardized, the production cost is reduced, and the uniformity of products in the same batch can be ensured due to the adoption of the external pipelines with uniform specification, and the stability of the quality of the products in the same batch is improved. Furthermore, the external pipeline is standardized, so that the welding positions of the external pipeline and the distributor are controllable, and the automatic production of products is facilitated.
The dispenser according to the invention described above may also have the following additional technical features:
in the above technical solution, further, the ratio of the length of the first tube segment of the first shunt tube to the length of the second tube segment of the first shunt tube 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 tube and the second shunt tube have the same length, and the first ratio is different from the second ratio.
In the technical scheme, the first shunt pipe and the second shunt pipe are of multi-section structures, and specifically, the first shunt pipe and the second shunt pipe comprise a first pipe section and a second pipe section. Wherein the first tube section and the second tube section of the first shunt tube have different inner diameters, and the first tube section and the second tube section of the second shunt tube have different inner diameters. It will be appreciated that the larger the proportion of the smaller of the inner diameters of the first and second tube segments over the length of the shunt tube, the smaller the flow of the shunt tube, and thus the flow of the first and second shunt tubes can be adjusted by adjusting the length proportions of the first and second tube segments. Specifically, 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 defined as a first ratio, and 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 defined as a second ratio.
Specifically, in the case where the inner diameter of the first leg of the first shunt tube is smaller than the inner diameter of the second leg of the first shunt tube, and the inner diameter of the first leg of the second shunt tube is smaller than the inner diameter of the second leg of the second shunt tube, the flow rate of the first shunt tube is larger than the flow rate of the second shunt tube if the first ratio is smaller than the second ratio, and, conversely, the flow rate of the first shunt tube is smaller than the flow rate of the second shunt tube if the first ratio is larger than the second ratio.
Further, since the length of the first shunt tube is equal to the length of the second shunt tube, the flow rate relationship between the first shunt tube and the second shunt tube can be determined directly by the comparison result of the lengths of the tube section with smaller inner diameter in the first shunt tube and the tube section with smaller inner diameter in the second shunt tube. Specifically, taking a case where 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 as an example, if the length of the first tube section of the first shunt tube is smaller than the length of the first tube section of the second shunt tube, the flow rate of the first shunt tube is larger than the flow rate of the second shunt tube, and conversely, if the length of the first tube section of the first shunt tube is larger than the length of the first tube section of the second shunt tube, the flow rate of the first shunt tube is smaller than the flow rate of the second shunt tube.
The first 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 limited to be different from the second 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, 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 flow of the distributor is adjusted, the flow is not required to be adjusted by setting the external pipelines of various specifications, the external pipelines of one size can be uniformly adopted to be connected with the distributor, the external pipelines are easier to standardize, 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 the products of the same batch is improved. Furthermore, the external pipeline is standardized, so that the welding positions of the external pipeline and the distributor are controllable, and the automatic production of products is facilitated.
In the above technical solution, further, a ratio of the first inner diameter of the first pipe section of the first shunt tube to the second inner diameter of the second pipe section of the first shunt tube 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 tube section of the second shunt tube and the second tube section of the second shunt tube have different inner diameters, and the ratio of the inner diameters of the second tube section of the second first shunt tube and the second tube section of the first shunt tube is defined as a fourth ratio.
The first shunt tube and the second shunt tube have the same length, and the case that the length of the first tube section of the first shunt tube is equal to the length of the first tube section of the second shunt tube, and 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, is taken as an example for explanation. It will be appreciated that in this case, the smaller the third ratio, the smaller the flow of the first shunt, and likewise, the smaller the fourth ratio, the smaller the flow of the second shunt. Thus, by adjusting the third ratio and the fourth ratio, the flow rates of the first shunt tube and the second shunt tube are adjusted.
The flow of the first shunt tube and the flow of the second shunt tube can be adjusted by adjusting the third ratio and the fourth ratio, so that the flow of the distributor is adjusted, the flow does not need to be adjusted by arranging external pipelines with various specifications, the external pipeline with one size can be uniformly adopted to be connected with the distributor, the external pipeline is more easily standardized, the production cost is reduced, and the consistency of products in the same batch can be ensured and the stability of the quality of the products in the same batch is improved because the external pipeline with uniform specification can be adopted. Furthermore, the external pipeline is standardized, so that the welding positions of the external pipeline and the distributor are 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 technical solution, 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 tube segments of differing inner diameters such that the flow rate of the shunt tube can be adjusted by adjusting the length and inner diameter of each tube 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.
The first inner diameter is smaller than the second inner diameter, the third inner diameter is smaller than the fourth inner diameter, and therefore the first shunt tube and the second shunt tube are arranged to be of a structure comprising tube sections with different inner diameters, the flow of the shunt tube can be adjusted by adjusting the ratio of the inner diameters of the tube sections, adjustment of the flow through the distributor is achieved, the flow is not required to be adjusted by setting external pipelines with various specifications, the external pipelines with one size can be uniformly adopted to be connected to the distributor, and standardization of the external pipelines is achieved.
In the above technical solution, further, the first shunt tube has the same outer diameter as the second shunt tube.
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 external dimension, the first shunt pipe and the second shunt pipe are easier to be connected with an external pipeline of the same specification, the weights of the first shunt pipe and the second shunt pipe of the same outer diameter dimension are close to each other, and the weights of all positions of the distributor are 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: a first wall comprising a first side and a second side facing away from the first side; the first shunt tube and the second shunt tube are arranged on the first side; the flow guiding part is arranged at the second side; the diversion part and the inner wall of the inflow pipe form a diversion cavity, and the diversion cavity is communicated with the first diversion pipe and the second diversion pipe.
In this technical scheme, the inflow pipe includes first wall, and first wall includes first side and deviates from the second side of 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, the inflow pipe is also provided with a flow guiding part, and the flow guiding part is arranged on the second side of the first wall, namely, the flow guiding part is arranged in the inner cavity of the inflow pipe.
The diversion part and the inner wall of the inflow pipe are separated by a certain distance, so that the diversion part and the inner wall of the inflow pipe form a diversion cavity, and the diversion cavity is communicated with the first diversion pipe and the second diversion pipe. After the refrigerant enters the inflow pipe, the refrigerant is split by the flow guide part, enters a split cavity between the flow guide part and the inner wall of the inflow pipe, and then enters the first split pipe and the second split pipe through the split cavity.
The flow guide part is arranged in the flow inlet pipe, so that the flow guide function is realized on the refrigerant, 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 guiding portion is a conical protrusion, and a cross-sectional area of one end of the flow guiding portion facing away from the first wall surface is smaller than a cross-sectional area of one end of the flow guiding portion facing the first wall surface.
In this technical scheme, the water conservancy diversion portion is toper protruding structure, specifically, the cross sectional area of water conservancy diversion portion one end that deviates from first wall is less than the cross sectional area of water conservancy diversion portion one end towards first wall. It can be understood that when the refrigerant flows through the flow guiding portion, the refrigerant flows along the wall surface of the flow guiding portion, the flow guiding portion is set to be a conical bulge, and one end with a smaller cross section in the conical bulge faces the inflow direction of the refrigerant, so that the obstruction of the flow guiding portion to the refrigerant can be reduced, the influence of the flow guiding portion on the flow velocity of the refrigerant is reduced, the refrigerant can flow along the wall surface of the flow guiding portion more easily, and the flow guiding function of the refrigerant is realized.
Through setting up the water conservancy diversion portion into the bellied structure of toper to set up the cross-sectional area that the water conservancy diversion portion deviates from first wall one end to be less than the cross-sectional area that the water conservancy diversion portion was towards first wall one end, thereby make the less one end of cross-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 chamber; the transition cavity is arranged between the inflow 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 the refrigerant enters the distributor, the refrigerant flows into the inflow cavity first, and the refrigerant flowing through the inflow cavity enters the transition cavity. The flow guiding part is arranged in the transition cavity, the refrigerant enters the transition cavity and contacts with the flow guiding part, and the flow guiding part shunts the refrigerant and guides the refrigerant so that the refrigerant flows into the first shunt pipe and the second shunt pipe in different flow paths.
It can be understood that if the refrigerant flows into the distributor, due to the change of the inner diameter of the pipeline, the flow velocity of the refrigerant changes to a certain extent, if the refrigerant is immediately split and guided at this time, an unstable state is easily caused, in order to keep the refrigerant in a stable flowing state, the refrigerant is firstly transited through the inflow cavity after flowing into the distributor, and then enters the transition cavity after flowing in the distributor in a stable state, and the guiding part in the transition cavity guides the refrigerant, so that the guiding of the refrigerant is realized, and the refrigerant can keep a stable flowing state.
Through dividing the inflow pipe into an inflow cavity and a transition cavity, the refrigerant can be stably transited through the inflow cavity, the stable flowing state of the refrigerant is kept, and then the refrigerant is guided through the guiding part in the transition cavity, so that the guiding of the refrigerant is realized, 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 along the direction toward the first wall surface.
In this embodiment, the cross-sectional area of the transition chamber increases gradually in a direction toward the first wall surface. It can be understood that, since the flow guiding portion is disposed in the transition cavity, and the flow guiding portion is integrally tapered, the cross-sectional area of the flow guiding portion gradually increases along the direction toward the first wall surface, if the size of the transition cavity at each position remains unchanged, the cross-sectional area of the flow distributing cavity between the flow guiding portion and the wall surface of the transition cavity gradually decreases due to the change of the cross-sectional area of the flow guiding portion, which affects the flow velocity of the refrigerant, resulting in an unstable state of the refrigerant. In order to reduce the influence of the flow guiding part on the flow velocity of the refrigerant, the transition cavity is of a variable cross-section structure, specifically, the cross-sectional area of the transition cavity in the direction of the first wall surface is gradually increased, so that the cross-sectional area of the flow dividing cavity is kept approximately unchanged, the influence on the flow velocity of the refrigerant is reduced, and the refrigerant is kept in a stable flowing state.
The cross section area of the transition cavity gradually increases towards the first wall surface, so that the cross section area of the diversion cavity is kept approximately 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 cross-sectional area of an end of the transition chamber facing the first wall surface is larger than a cross-sectional area of any position of the inflow chamber.
In the technical scheme, the cross section area of one end of the transition cavity facing the first wall surface is larger than the cross section area of any position of the inflow cavity. Specifically, the cross-sectional area of one side of the transition cavity close to the inflow cavity is the same as the cross-sectional area of the inflow cavity, so that the refrigerant is kept stable when flowing into the transition cavity from the inflow cavity. In order to keep the cross-sectional area of the diversion chamber between the chamber wall and the diversion portion of the transition chamber approximately unchanged, the cross-sectional area of the transition chamber is gradually increased in the direction towards the first wall surface, that is, the cross-sectional area of the end of the transition chamber towards the first wall surface is the maximum cross-sectional area of the transition chamber, so that the cross-sectional area of the end of the transition chamber towards the first wall surface is larger than the cross-sectional area of any position of the inflow chamber.
By making the cross-sectional area of the end of the transition cavity facing the first wall surface larger than the cross-sectional area of any position of the inflow cavity, the cross-sectional area of the diversion cavity between the cavity wall of the transition cavity and the diversion part can be kept approximately unchanged, so that the refrigerant in the diversion cavity can be kept in a stable flowing state.
In the above technical solution, the dispenser further includes a plurality of connection pipes for connecting with an external pipeline; 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 the at least one first shunt pipe and the at least one second shunt pipe, namely, each first shunt pipe and each second shunt pipe are respectively provided with one connecting pipe. The external pipelines are connected with the first shunt pipe and the second shunt pipe through connecting pipes, so that the refrigerant can flow into each external pipeline through the distributor.
Through set up the connecting pipe in first shunt tubes and second shunt tubes, make external pipeline can be connected with first shunt tubes and second shunt tubes through the connecting pipe, and then make refrigerant accessible distributor flow into each external pipeline. The first shunt pipe and the second shunt pipe with different sizes can be connected with the external pipeline with the same specification by arranging the connecting pipes with the same specification in the first shunt pipe and the second shunt pipe.
In the above technical solution, further, the inner diameter of the connecting tube is larger than the inner diameter of any position of the first shunt tube and the second shunt tube; the outer diameter of the connecting tube is larger than the outer diameter of the first shunt tube and the outer diameter of the second shunt tube.
In this technical scheme, in order to facilitate the connection of the external connection pipe to the connection pipe, the size of the connection pipe is defined. Specifically, the inner diameter of the connecting tube is larger than the inner diameter of any position of the first shunt tube and the second shunt tube; the outer diameter of the connecting tube is larger than the outer diameter of the first shunt tube and the outer diameter of the second shunt tube. 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.
By making the inner diameter of the connecting tube larger than the inner diameter of any position of the first shunt tube and the second shunt tube; the external diameter of connecting pipe is greater than the external diameter of first shunt tubes and the external diameter of second shunt tubes, can play limiting displacement to external piping when external piping inserts in the connecting pipe, be convenient for external piping and the connection of distributor.
In the above technical solution, further, at least one first shunt tube and at least one second shunt tube are disposed on a side close to an outer edge of the first wall surface.

In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
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 described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
A dispenser 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.
Embodiment one:
as shown in fig. 1 and 4, an embodiment of a first aspect of the present invention proposes a dispenser 100 for an air conditioner, comprising: a flow inlet pipe 110; at least one first shunt tube 120 in communication with the inlet tube 110; at least one second shunt tube 130 in communication with the inlet tube 110; wherein the first shunt 120 and the second shunt 130 differ in volume.
The dispenser 100 provided by the application is used for an air conditioner and comprises an inflow 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 communicated with the inflow pipe 110. The distributor 100 is provided in the flow path of the heat exchanger, and is configured to split the refrigerant in the flow path of the heat exchanger and adjust the flow rate of each flow path. Specifically, the refrigerant flows into the distributor 100 from the inflow pipe 110, 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 with 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 as to realize the diversion of the refrigerant.
Further, the first shunt 120 and the second shunt 130 differ in volume. The refrigerant enters the flow divider from the inflow pipe 110, flows into the first shunt pipe 120 and the second shunt pipe 130 respectively, and flows into the external pipeline through the first shunt pipe 120 and the second shunt pipe 130. It will be appreciated that the flow rate of the refrigerant in each of the external lines is related to the volume of the first bypass 120 or the second bypass 130 connected to each of the external lines. Specifically, the lengths of the first shunt tube 120 and the second shunt tube 130 are the same, 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 of refrigerant 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 connection pipeline connected with the first shunt tube 120 is smaller than that of the external connection pipeline connected with the second shunt tube 130, and the effect of adjusting the flow rates of the external connection pipelines through the distributor 100 is achieved.
By providing at least one first shunt tube 120 and at least one second shunt tube 130 in the distributor 100, the refrigerant flows into each shunt tube when flowing through the distributor 100, thereby realizing the effect of shunting the refrigerant. 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 first shunt tube 120 and the second shunt tube 130 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 achieved, the flow rate is not required to be adjusted by setting the external pipeline with various specifications, the external pipeline with one size is uniformly adopted to be connected with the distributor 100, the external pipeline is more easily standardized, the production cost is reduced, and the uniformity of products in the same batch can be ensured due to the adoption of the external pipeline with uniform specification, and the stability of the quality of the products in the same batch is improved. Further, by standardizing the external pipeline, the welding position of the external pipeline and the distributor 100 is controllable, thereby being beneficial to realizing the automatic production of products.

in one embodiment, as shown in conjunction with fig. 2, 3 and 5, based on the first embodiment, the ratio of the length of the first section of the first shunt 120 to the length of the second section of the first shunt 120 is a first ratio; the ratio of the length of the first tube section of the second shunt tube 130 to the length of the second tube section of the second shunt tube 130 is a second ratio; the first shunt 120 and the second shunt 130 have the same length and the first ratio is different from the second ratio.
In this embodiment, the first shunt 120 and the second shunt 130 are each of a multi-segment structure, and specifically, the first shunt 120 and the second shunt 130 each include a first segment and a second segment. Wherein the first leg and the second leg of the first shunt tube 120 have different inner diameters, and the first leg and the second leg of the second shunt tube 130 have different inner diameters. It will be appreciated that the larger the proportion of the smaller of the first and second tube segments that is the entire length of the shunt tube, the smaller the flow of the shunt tube, and thus the flow of the first and second shunt tubes 120, 130 can be adjusted by adjusting the length proportions of the first and second tube segments. 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 since the lengths of the first shunt pipe 120 and the second shunt pipe 130 are the same, the flow rates of the first shunt pipe 120 and the second shunt pipe 130 are different under the condition that the first ratio and the second ratio are different, so that the effect of adjusting the flow rate of the refrigerant through the shunt is realized.
Specifically, in the case where the inner diameter of the first leg of the first shunt tube 120 is smaller than the inner diameter of the second leg of the first shunt tube 120 and the inner diameter of the first leg of the second shunt tube 130 is smaller than the inner diameter of the second leg of the second shunt tube 130, if the first ratio is smaller than the second ratio, the flow rate of the first shunt tube 120 is larger than the flow rate of the second shunt tube 130, and conversely, if the first ratio is larger than the second ratio, the flow rate of the first shunt tube 120 is smaller than the flow rate of the second shunt tube 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 determined directly by comparing the lengths of the tube sections with smaller inner diameters of the first shunt tube 120 and the tube sections with smaller inner diameters of the second shunt tube 130. Specifically, taking a case where the inner diameter of the first leg of the first shunt tube 120 is smaller than the inner diameter of the second leg of the first shunt tube 120 and the inner diameter of the first leg of the second shunt tube 130 is smaller than the inner diameter of the second leg of the second shunt tube 130 as an example, if the length of the first leg of the first shunt tube 120 is smaller than the length of the first leg of the second shunt tube 130, the flow rate of the first shunt tube 120 is larger than the flow rate of the second shunt tube 130, and conversely, if the length of the first leg of the first shunt tube 120 is larger than the length of the first leg of the second shunt tube 130, the flow rate of the first shunt tube 120 is smaller than the flow rate of the second shunt tube 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 is different from 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, the flow of the first shunt pipe 120 and the second shunt pipe 130 can be adjusted by adjusting the first ratio and the second ratio, the flow of the distributor 100 is adjusted, the flow is not required to be adjusted by arranging external pipelines of various specifications, the external pipelines of one size can be uniformly adopted to be connected with the distributor 100, the external pipelines are more easily standardized, the production cost is reduced, and the consistency of products of the same batch can be ensured and the stability of the quality of the products of the same batch is improved because the external pipelines of uniform specifications can be adopted. Further, by standardizing the external pipeline, the welding position of the external pipeline and the distributor 100 is controllable, thereby being beneficial to realizing the automatic production of products.
Embodiment III:
in one specific embodiment based on any of the above embodiments, as shown in fig. 2, 3 and 5, the ratio of the first inner diameter of the first section of the first shunt 120 to the second inner diameter of the second section of the first shunt 120 is a third ratio; the ratio of the third inner diameter of the first leg of the second shunt tube 130 to the fourth inner diameter of the second leg of the second shunt tube 130 is a fourth ratio; the third ratio is different from the fourth ratio.
In this embodiment, the first leg of the first shunt 120 and the second leg of the first shunt 120 have different inner diameters, and the ratio of the inner diameters of the first leg of the first shunt 120 and the second leg of the first shunt 120 is defined as a third ratio. The first leg of the second shunt tube 130 and the second leg of the second shunt tube 130 have different inner diameters, and the ratio of the inner diameters of the second leg of the second first shunt tube 120 and the second leg of the first shunt tube 120 is a fourth ratio.
The first shunt tube 120 has the same length as the second shunt tube 130, and the case where the length of the first tube section of the first shunt tube 120 is equal to the length of the first tube section of the second shunt tube 130, and the inner diameter of the first tube section of the first shunt tube 120 is smaller than the inner diameter of the second tube section of the first shunt tube 120, and the inner diameter of the first tube section of the second shunt tube 130 is smaller than the inner diameter of the second tube section of the second shunt tube 130 is 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 120 and, likewise, the smaller the fourth ratio, the smaller the flow of the second shunt 130. Thus, by adjusting the third ratio and the fourth ratio, the flow rates of the first shunt 120 and the second shunt 130 are adjusted.
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 is different from 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, the flow of the first shunt pipe 120 and the second shunt pipe 130 can be adjusted by adjusting the third ratio and the fourth ratio, the flow of the dispenser 100 is adjusted, the flow is not required to be adjusted by arranging external pipelines with various specifications, the external pipelines with one size can be uniformly adopted to be connected with the dispenser 100, the external pipelines are easier to standardize, the production cost is reduced, and the consistency of products in the same batch can be ensured and the stability of the quality of the products in the same batch can be improved because the external pipelines with uniform specifications can be adopted. Further, by standardizing the external pipeline, the welding position of the external pipeline and the distributor 100 is controllable, thereby being beneficial to realizing the automatic production of products.
Embodiment four:
in a specific embodiment based on any of the above embodiments, as shown in connection with 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 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 tube segments of differing inner diameters such that the flow rate of the shunt tube can be adjusted by adjusting the length and inner diameter of each tube segment. Taking the first shunt 120 as an example, in the case where the first inner diameter of the first tube segment of the first shunt 120 is smaller than the second inner diameter of the second tube segment of the first shunt 120, the smaller the ratio of the first inner diameter to the second inner diameter, the smaller the flow rate of the first shunt 120.
The first inner diameter is smaller than the second inner diameter, the third inner diameter is smaller than the fourth inner diameter, and therefore the first shunt tube 120 and the second shunt tube 130 are arranged to be of a tube section structure comprising different inner diameters, the flow of the shunt tube can be adjusted by adjusting the ratio of the inner diameters of the tube sections, the flow can be adjusted through the distributor 100, the flow can be adjusted without the need of arranging external pipelines of various specifications, the external pipelines of one size can be uniformly connected to the distributor 100, and the standardization of the external pipelines can be achieved.
Fifth embodiment:
in one embodiment, as shown in connection with fig. 1 and 4, based on any of the above embodiments, the first shunt 120 has the same outer diameter as the second shunt 130.
In this embodiment, the outer diameters of the first shunt 120 and the second shunt 130 are the same, so that at least one first shunt 120 and at least one second shunt 130 can be disposed in the dispenser 100 with uniform external dimensions, so that the first shunt 120 and the second shunt 130 are easier to connect with external pipelines of the same specification, and the weights of the first shunt 120 and the second shunt 130 with the same outer diameter dimension are close to each other, so that the weights of the various positions of the dispenser 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 are easier to be connected with external pipelines of the same specification, and further standardization of the external pipelines of the distributor 100 is achieved.
Example six:
as shown in fig. 3 and 6, in a specific embodiment based on any of the above embodiments, the inflow 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 120 and the second shunt 130 are disposed on a first side; a diversion part 112 arranged at the second side; the diversion portion 112 and the inner wall of the inflow tube 110 constitute a diversion cavity 113, and the diversion cavity 113 communicates with the first diversion tube 120 and the second diversion tube 130.
In this embodiment, the inlet tube 110 includes a first wall 111, the first wall 111 includes a first side and a second side facing away from the first side, and the first shunt tube 120 and the second shunt tube 130 are disposed on the first side. The second side of the first wall surface 111 faces the inner cavity of the intake pipe 110, and a flow guiding part 112 is further disposed in the intake pipe 110, and the flow guiding part 112 is disposed on the second side of the first wall surface 111, that is, the flow guiding part 112 is disposed in the inner cavity of the intake pipe 110.
A certain distance is left between the diversion part 112 and the inner wall of the inflow tube 110, so that the diversion part 112 and the inner wall of the inflow tube 110 form a diversion cavity 113, and the diversion cavity 113 is communicated with the first diversion tube 120 and the second diversion tube 130. After the refrigerant enters the inflow tube 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 inflow tube 110, and then enters the first split tube 120 and the second split tube 130 through the split cavity 113.
By providing the flow guide portion 112 in the inflow pipe 110, the refrigerant is guided to the first and second branch pipes 120 and 130 uniformly.
Embodiment 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 surface 111 is smaller than a cross-sectional area of an end of the flow guiding portion 112 facing toward the first wall surface 111.
In this embodiment, the flow guiding portion 112 has a conical convex structure, specifically, a cross-sectional area of an end of the flow guiding portion 112 facing away from the first wall surface 111 is smaller than a cross-sectional area of an end of the flow guiding portion 112 facing toward the first wall surface 111. It can be understood that when the refrigerant flows through the flow guiding portion 112, the refrigerant flows along the wall surface of the flow guiding portion 112, the flow guiding portion 112 is configured as a conical protrusion, and the end with the smaller cross-sectional area in the conical protrusion faces the inflow direction of the refrigerant, so that the obstruction of the flow guiding portion 112 to the refrigerant can be reduced, the influence of the flow guiding portion 112 to the flow velocity of the refrigerant can be reduced, and the refrigerant can flow along the wall surface of the flow guiding portion 112 more easily, thereby realizing the flow guiding function to the refrigerant.
Through setting up the water conservancy diversion portion 112 into the bellied structure of toper to set the cross-sectional area of water conservancy diversion portion 112 one end that deviates from first wall 111 to be less than the cross-sectional area of water conservancy diversion portion 112 one end towards first wall 111, thereby make the less one end of cross-sectional area of the bellied water conservancy diversion portion 112 of toper face the inflow direction of refrigerant, thereby reduce the hindrance of water conservancy diversion portion 112 to the refrigerant, reduce the influence of water conservancy diversion portion 112 to the refrigerant velocity of flow, and can make the refrigerant flow along the wall of water conservancy diversion portion 112 more easily, thereby realize the water conservancy diversion function to the refrigerant.
Example eight:
as shown in fig. 3 and 6, in a specific embodiment based on any of the above embodiments, the inflow pipe 110 includes: an inflow cavity 114; the transition cavity 115 is disposed between the inflow cavity 114 and the first wall surface 111, and the flow guiding portion 112 is disposed in the transition cavity 115.
In this embodiment, the inlet tube 110 comprises an inlet chamber 114 and a transition chamber 115, wherein the transition chamber 115 is disposed between the inlet chamber 114 and the first wall 111. After the refrigerant enters the distributor 100, the refrigerant flows into the inflow cavity 114, and the refrigerant flowing through the inflow cavity 114 enters the transition cavity 115. The flow guiding part 112 is arranged in the transition cavity 115, and the refrigerant is contacted with the flow guiding part 112 after entering the transition cavity 115, and the flow guiding part 112 shunts and guides the refrigerant so that the refrigerant flows into the first shunt pipe 120 and the second shunt pipe 130 in different flow paths.
It will be appreciated that if the refrigerant flows into the distributor 100, due to the change of the inner diameter of the pipeline, the flow rate of the refrigerant will change to a certain extent, if the refrigerant is split and guided immediately at this time, an unstable state is easily caused to occur in the refrigerant, in order to keep the refrigerant in a stable flowing state, the refrigerant is first transited through the inflow cavity 114 after flowing into the distributor 100, and then enters the transition cavity 115 after flowing in the distributor 100 in a stable state, and the guiding portion 112 in the transition cavity 115 guides the refrigerant, so that the guiding of the refrigerant is realized, and the refrigerant can keep 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, the stable flowing state of the refrigerant is maintained, and then the refrigerant is guided through the guiding part 112 in the transition cavity 115, so that the guiding of the refrigerant is realized, and the refrigerant can be kept in the stable flowing state.
Example nine:
in a specific embodiment based on any of the above embodiments, as shown in connection with fig. 3 and 6, the cross-sectional area of the transition chamber 115 gradually increases in a direction toward the first wall surface 111.
In this embodiment, the transition chamber 115 has a gradually increasing cross-sectional area in a direction toward the first wall surface 111. It can be understood that, since the flow guiding portion 112 is disposed in the transition cavity 115, and the flow guiding portion 112 is tapered as a whole, the cross-sectional area of the flow guiding portion 112 gradually increases along the direction toward the first wall surface 111, if the size of the transition cavity 115 at each position is kept unchanged, the cross-sectional area of the flow splitting cavity 113 between the flow guiding 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 guiding portion 112, which affects the flow velocity of the refrigerant, resulting in an unstable state of the refrigerant. In order to reduce the influence of the flow guiding portion 112 on the flow velocity of the refrigerant, the transition chamber 115 is configured to have a variable cross section, specifically, the cross section of the transition chamber 115 in the direction of the first wall surface 111 is gradually increased, so that the cross section of the flow splitting chamber 113 is kept substantially unchanged, the influence on the flow velocity of the refrigerant is reduced, and the refrigerant is kept in a stable flow state.
By gradually increasing the cross-sectional area of the transition chamber 115 in the direction of the first wall surface 111, the cross-sectional area of the bypass chamber 113 is kept substantially constant, the influence on the flow velocity of the refrigerant is reduced, and the refrigerant is kept in a stable flow state.
Further, the cross-sectional area of the end of the transition chamber 115 facing the first wall 111 is larger than the cross-sectional area of any position of the inflow chamber 114.
In this embodiment, the cross-sectional area of the end of the transition chamber 115 facing the first wall 111 is larger than the cross-sectional area of any position of the inflow chamber 114. Specifically, the cross-sectional area of the transition chamber 115 near the side of the inflow chamber 114 is the same as the cross-sectional area of the inflow chamber 114, so that the refrigerant is kept stable when flowing from the inflow chamber 114 into the transition chamber 115. In order to keep the cross-sectional area of the diversion chamber 113 between the chamber wall of the transition chamber 115 and the diversion portion 112 substantially unchanged, the cross-sectional area of the transition chamber 115 is set to gradually increase in the direction toward the first wall surface 111, that is, the cross-sectional area of the end of the transition chamber 115 toward the first wall surface 111 is the maximum cross-sectional area of the transition chamber 115, and therefore, the cross-sectional area of the end of the transition chamber 115 toward the first wall surface 111 is larger than the cross-sectional area of any position of the inflow 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 inflow chamber 114, it is possible to ensure that the cross-sectional area of the diversion chamber 113 between the chamber wall of the transition chamber 115 and the diversion portion 112 remains substantially unchanged, thereby ensuring that the refrigerant maintains a stable flow state in the diversion chamber 113.
Example ten:
in a specific embodiment based on any of the above embodiments, as shown in fig. 1, 3 and 5, the dispenser 100 further includes a plurality of connection pipes 140 for connecting with external pipelines; 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, the dispenser 100 is further provided with a plurality of connection pipes 140, and the connection pipes 140 are used for connecting external pipelines. Wherein, a plurality of connecting pipes 140 are respectively arranged at least one first shunt pipe 120 and at least one second shunt pipe 130, namely, each first shunt pipe 120 and each second shunt pipe 130 are provided with one connecting pipe 140. The external connection pipes are connected with the first shunt pipe 120 and the second shunt pipe 130 through the connection pipe 140, so that the refrigerant can flow into each external connection pipe through the distributor 100.
By providing the connection pipe 140 in the first shunt pipe 120 and the second shunt pipe 130, the external connection pipe can be connected with the first shunt pipe 120 and the second shunt pipe 130 through the connection pipe 140, and thus the refrigerant can flow into each external connection pipe through the distributor 100. By providing the same-sized connection pipe 140 in the first shunt pipe 120 and the second shunt pipe 130, the first shunt pipe 120 and the second shunt pipe 130 with different sizes can be connected with the same-sized external connection pipe.
Further, the inner diameter of the connection tube 140 is larger than the inner diameter of any position of the first shunt tube 120 and the second shunt tube 130; the outer diameter of the connection tube 140 is greater than the outer diameter of the first shunt tube 120 and the outer diameter of the second shunt tube 130.
In this embodiment, in order to facilitate the connection of the external connection pipe to the connection pipe 140, the size of the connection pipe 140 is defined. Specifically, the inner diameter of the connection tube 140 is larger than the inner diameter of any position of the first shunt tube 120 and the second shunt tube 130; the outer diameter of the connection tube 140 is greater than the outer diameter of the first shunt tube 120 and the outer diameter of the second shunt tube 130. It can be appreciated that, in the case that the inner diameter of the connection 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 connection pipe can be inserted into the connection pipe 140, and at the root of the connection pipe 140, the portion smaller than the inner diameter of the connection pipe 140 automatically forms a limited wall surface, so as to limit the external connection pipe, thereby preventing the external connection pipe from continuously extending into the first shunt pipe 120 or the second shunt pipe 130.
By making the inner diameter of the connection tube 140 larger than the inner diameter of either of the first shunt tube 120 and the second shunt tube 130; the outer diameter of the connection pipe 140 is larger than the outer diameter of the first shunt pipe 120 and the outer diameter of the second shunt pipe 130, so that the external connection pipe can play a limiting role when the external connection pipe is inserted into the connection pipe 140, and the connection between the external connection pipe and the distributor 100 is facilitated.
