A dispenser 100 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

As shown in fig. 1, a distributor 100 according to an embodiment of the present utility model includes a distributor body 1, an inlet and outlet pipe 2, a branch pipe 3, and a flow equalizing assembly 4.

Specifically, referring to fig. 1, the distributor body 1 is a straight cylinder, and the distributor body 1 has a distribution chamber through which a refrigerant can pass. In one specific example, as shown in fig. 1, the dispenser body 1 is cylindrical. Of course, the present utility model is not limited thereto, and the dispenser body 1 may be another shape or a cylinder with a variable diameter.

Further, referring to fig. 1, the liquid inlet and outlet pipe 2 and the branch pipe 3 are respectively connected to two opposite ends of the distributor body 1, and the liquid inlet and outlet pipe 2 and the branch pipe 3 are both communicated with the distribution cavity, the diameters of the liquid inlet and outlet pipe 2 and the branch pipe 3 are smaller than those of the distribution cavity, and the refrigerant enters the distribution cavity of the distributor body 1 from the liquid inlet and outlet pipe 2, so that the gas phase and the liquid phase can be uniformly mixed due to the sudden expansion of the diameters. Further, referring to fig. 1, the number of the branch pipes 3 is plural, so that the refrigerant in the distribution cavity can flow out from plural channels, which can increase the path of the refrigerant to the heat exchanger body 5, realize the branching of the refrigerant, improve the heat exchange efficiency of the heat exchanger assembly 200, and improve the use experience of users. For example, the branch pipes 3 may be two, three, four, five or six, etc. spaced apart. In one embodiment, and with reference to fig. 1, the branch pipes 3 are three spaced apart.

Still further, referring to fig. 2, the flow equalizing assembly 4 includes a flow equalizing member 41 and a gear regulator 42, the flow equalizing member 41 having a flow equalizing cavity 411, the gear regulator 42 being rotatably disposed in the flow equalizing cavity 411, the flow equalizing assembly 4 being connected to the plurality of flow dividing branches 3 and the flow equalizing cavity 411 being in communication with the plurality of flow dividing branches 3, the flow equalizing assembly 4 being configured to allow only gas to flow between the plurality of flow dividing branches 3, it being defined that the gas in the refrigerant can flow in the plurality of flow dividing branches 3 and the liquid can not flow in the plurality of flow dividing branches 3.

It will be appreciated that the refrigerant may flow from one branch pipe 3 to the equalizing cavity 411, and since the equalizing component 4 only allows the gas to flow between the plurality of branch pipes 3, the gas in the refrigerant may flow to the other branch pipe 3 through the equalizing cavity 411 by pushing the gear regulator 42 to rotate, so that the gas may flow from one branch pipe 3 to the other branch pipe 3, so that the pressures in the different branch pipes 3 may be kept consistent, and the liquid flow in each branch pipe 3 may finally tend to be evenly split, so that the heat exchange capability of the heat exchanger component 200 may be improved, the heating or cooling effect of the air conditioner may be ensured, and the use experience of the user may be improved.

According to the distributor 100 of the embodiment of the utility model, the plurality of branch pipes 3 are connected through the flow equalizing component 4, the flow equalizing cavity 411 communicates the plurality of branch pipes 3, the flow equalizing component 4 only allows gas to flow between the plurality of branch pipes 3, so that the gas can flow from one branch pipe 3 to the other branch pipe 3 through the flow equalizing cavity 411, the pressures in different branch pipes 3 are kept consistent, the liquid flow in each branch pipe 3 finally tends to be evenly split, the heat exchanging capability of the heat exchanger component 200 can be improved, the heating or refrigerating effect of the air conditioner is ensured, and the use experience of a user is improved.

In some embodiments of the present utility model, referring to fig. 2, the flow equalizer 41 includes a center piece 412 and a plurality of connection branches 413. Specifically, the center member 412 has a center chamber, a plurality of connecting branch pipes 413 are spaced apart in a circumferential direction of the center member 412 and one end is connected to the center member 412, each connecting branch pipe 413 communicates with the center chamber, an intra-pipe space of the plurality of connecting branch pipes 413 and the center chamber together form a flow equalizing chamber 411, the other ends of the plurality of connecting branch pipes 413 are respectively connected and communicate with the plurality of branch pipes 3, the gear regulator 42 is rotatably provided in the center chamber, a gap is provided between an outer wall surface of the gear regulator 42 and an inner wall surface of the center member 412, a diameter of R32 (difluoromethane) liquid molecules is 20 μm to 100 μm, a diameter of R32 gas molecules is 0.0003 μm to 0.0004 μm, and a gap between an outer wall surface of the gear regulator 42 and an inner wall surface of the center member 412 is greater than 0.0004 μm and less than a minimum diameter of R32 liquid molecules is 20 μm, so that liquid and gas can be separated at the gear regulator 42, only the gas can pass through the center chamber, the liquid can be blocked outside the center chamber, the liquid can still remain in the branch pipes 3, and the gas can flow only between the branch pipes 3 can flow only.

The number of the connecting branch pipes 413 is identical to the number of the branch pipes 3. In a specific example, referring to fig. 2, the flow equalizer 41 includes a center member 412 and three connecting branch pipes 413, the three connecting branch pipes 413 being spaced apart in a circumferential direction of the center member 412 and connected at one end to the center member 412, and the other ends of the three connecting branch pipes 413 being connected and communicating with the three flow dividing branch pipes 3, respectively.

It will be appreciated that when the pressure in the first branch 3 is greater than the pressure in the second branch 3, the refrigerant in the first branch 3 may flow to the first connecting branch 413, and the gas in the first connecting branch 413 may urge the gear regulator 42 to rotate toward the second connecting branch 413, thereby allowing the gas in the first branch 3 to enter the second branch 3, increasing the mass of the flow in the second branch 3, thereby increasing the frictional pressure drop in the second branch 3, and thus the pressure in the second branch 3, and at the same time, the pressure in the first branch 3 is gradually decreased until the pressure in the second branch 3 is equal to the pressure in the first branch 3. Wherein the first connecting branch 413 is connected to and communicates with the first branch 3, and the second connecting branch 413 is connected to and communicates with the second branch 3. In addition, when the pressure of one branch pipe 3 is higher than the average value of the pressures of the plurality of branch pipes 3, the gas in the branch pipe 3 flows to the branch pipe 3 lower than the average value of the pressures of the plurality of branch pipes 3 through the gear regulator 42 in the flow equalizing chamber 411 until the pressures in the plurality of branch pipes 3 are equal.

In a further embodiment of the present utility model, referring to fig. 3, the inner diameter of the connecting branch 413 is D1, and the outer diameter of the gear adjuster 42 is D2, satisfying: D2/D1 is more than or equal to 0.8 and less than or equal to 2.5. For example, D2/D1 may be 0.8, 1, 1.2, 1.5, 1.7, 2, 2.3, or 2.5.

It will be appreciated that when D2/D1 < 0.8, the ratio of D2/D1 is too small, the outer diameter D2 of the gear regulator 42 is smaller than the inner diameter D1 of the connecting branch pipe 413, and when a large pressure difference between different branch pipes 3 is encountered, the amount of gas flowing between the different branch pipes 3 is required to be large, and a large amount of gas in the branch pipe 3 with large flow in the pipe flows into the central cavity to push the gear regulator 42 to rotate, because the amount of gas is large, the rotating speed of the gear regulator 42 is too fast, it is difficult to accurately control the gas to the connecting branch pipe 413 to balance the pressure in the different branch pipes 3, and a large amount of time is required to uniformly split the flow of liquid in each branch pipe 3; when D2/D1 is larger than 2.5, the ratio of D2/D1 is too large, the outer diameter D2 of the gear regulator 42 is far larger than the inner diameter D1 of the connecting branch pipe 413, when the pressure difference between different branch pipes 3 is small, the amount of gas required to flow between the different branch pipes 3 is small, a small amount of gas in the branch pipe 3 with larger flow in the pipe flows into the central cavity, the situation that the rotating speed of the gear regulator 42 is too slow is easy to generate due to the small amount of gas, even the situation that the gear regulator 42 cannot be pushed to rotate is generated, so that the pressure in the different branch pipes 3 is difficult to balance, and a great amount of time is required to uniformly split the liquid flow in each branch pipe 3, even uniform splitting cannot be achieved; and when D2/D1 is less than or equal to 0.8 and less than or equal to 2.5, the ratio of the outer diameter D2 of the gear regulator 42 to the inner diameter D1 of the connecting branch pipe 413 is proper, so that the pressures in different branch pipes 3 can be balanced, the liquid flow in each branch pipe 3 can be uniformly distributed, the heat exchange capacity of the heat exchanger assembly 200 can be improved, and the use experience of a user can be improved.

In addition, the length of the central member 412 in the longitudinal direction (a direction shown in fig. 1) of the distributor 100 is less than or equal to the outer diameter D1 of the gear regulator 42, so that the gas in the central cavity is not excessively accumulated, the time consumed by the gas flowing from one branch pipe 3 to the other branch pipe 3 is reduced, the pressure in each branch pipe 3 is made to be uniform as soon as possible, the liquid flow in each branch pipe 3 tends to be uniformly split as soon as possible, the heat exchange capability of the heat exchanger assembly 200 can be improved, and the use experience of users can be improved.

In a further embodiment of the present utility model, the lengths of the plurality of connecting branches 413 are the same, so that the paths of the refrigerant flowing through each connecting branch 413 are the same, which is advantageous for the uniformity of the flow in the branch pipe 3. Further, the pipe diameters of the connecting branch pipes 413 are the same, so that the flow quality in the connecting branch pipes 413 can be the same, and the flow uniformity in the branch pipe 3 is facilitated. In a specific example, referring to fig. 2, the lengths and the pipe diameters of the plurality of connecting branch pipes 413 are the same, so that the production and the manufacturing of the flow equalization assembly 4 are facilitated, the production and the development costs of the distributor 100 can be reduced, and the plurality of connecting branch pipes 413 with the same lengths and pipe diameters can form a stable structure, so that the stability of the flow equalization assembly 4 is improved.

In some embodiments, the plurality of connecting branches 413 may be the same length and different pipe diameters; alternatively, the plurality of connecting branches 413 may be different in length and identical in pipe diameter; still alternatively, the lengths and the pipe diameters of the plurality of connecting branch pipes 413 may be the same, and the lengths and the pipe diameters of the plurality of connecting branch pipes 413 may be selected according to the actual requirements of different distributors 100, so as to meet different use requirements.

Of course, the present utility model is not limited thereto, and the lengths and pipe diameters of the plurality of connection branches 413 may be different, which is not limited thereto.

In some embodiments of the present utility model, the total length of the branch pipes 3 is L3, and the distance between the position of the corresponding branch pipe 3 communicating with the equalizing cavity 411 and the end of the branch pipe 3 near the distributor body 1 is L4, which satisfies the following conditions: L4/L3 is more than or equal to 0.3 and less than or equal to 0.8. It should be noted that, the position where the corresponding branch pipe 3 communicates with the flow equalizing chamber 411 is the center plane of the flow equalizing assembly 4 in the thickness direction (the direction a shown in fig. 1).

It will be appreciated that the amount of heat transfer during nominal and intermediate refrigeration conditions varies with L4/L3, as shown with reference to FIG. 5. When L4/L3 is less than 0.3, the position of the flow dividing branch pipe 3 communicated with the flow equalizing cavity 411 is too close to the distributor body 1, the pressure difference in different flow dividing branch pipes 3 is not displayed, the pressure effect of the received flow equalizing assembly 4 is not obvious, and the uniformity cannot be improved obviously; when L4/L3 is more than 0.8, the position of the split branch pipe 3 communicated with the flow equalizing cavity 411 is too close to the heat exchanger body 5, liquid and gas are carried with each other, the pressure-equalizing effect of the received flow equalizing component 4 is not obvious, and the flow equalizing performance cannot be improved obviously; when the ratio of L4/L3 is more than or equal to 0.3 and less than or equal to 0.8, the position of the branch pipe 3 communicated with the flow equalizing cavity 411 is proper from the distributor body 1 to the heat exchanger body 5, the pressure difference of different branch pipes 3 is obvious, the gear regulator 42 can fully exert the pressure equalizing effect, the pressure in the branch pipes 3 tends to be equal after a period of pressure equalization, the flow uniformity of the branch pipes 3 is improved, and the heat exchanging capacity of the heat exchanger assembly 200 can be obviously improved. For example, L4/L3 may be 0.3, 0.4, 0.5, 0.6, 0.7, or 0.8.

In some embodiments of the present utility model, the positions on each of the branch pipes 3, which are communicated with the flow equalizing cavity 411, are the same, so that the refrigerant can flow to the flow equalizing cavity 411 at the same position in the branch pipe 3, the time that the refrigerant in each branch pipe 3 is subjected to gas-liquid separation is the same, the pressures in the branch pipes 3 can be balanced as soon as possible, and the heat exchange capacity of the heat exchanger assembly 200 is improved.

Further, the pipe diameters of the plurality of branch pipes 3 are the same, so that the flow quality in the plurality of branch pipes 3 is the same, and the uniformity of the flow in the branch pipes 3 is facilitated. In a specific example, referring to fig. 1, the lengths and the pipe diameters of the plurality of branch pipes 3 are the same, so that the production and development costs of the branch pipes 3 can be reduced, and the production and the manufacture of the distributor 100 are facilitated.

In some embodiments, the multiple branch pipes 3 may have the same length and different pipe diameters; alternatively, the multiple branch pipes 3 may have different lengths and the same pipe diameters; or, the lengths and the pipe diameters of the plurality of branch pipes 3 can be the same, and the lengths and the pipe diameters of the plurality of branch pipes 3 can be selected according to the actual demands of different distributors 100, so as to meet different use demands.
