Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, and particularly to a dispenser and an air conditioning device. Background Art

[0002] Generally, the refrigerant in a gas-liquid mixture in a dispenser can only undergo a single gas-liquid separation process, resulting in a small amount of gas remaining in the liquid, which affects the gas-liquid separation effect of the dispenser. Summary of the Invention

[0003] In view of this, it is necessary to provide a dispenser and an air conditioning device that can improve the gas-liquid separation effect of the dispenser.

[0004] The present invention provides a dispenser, which includes a dispensing main body, an inlet pipe, an outlet liquid pipe, and an outlet gas pipe; the dispensing main body is provided with a cavity, and a partition member is arranged in the cavity. The partition member divides the cavity into a first separation cavity and a second separation cavity; the partition member is provided with a communication hole that communicates the first separation cavity and the second separation cavity, so that the liquid refrigerant enters the second separation cavity from the first separation cavity through the communication hole. The inlet pipe, the outlet liquid pipe, and the outlet gas pipe are all connected to the dispensing main body. The inlet pipe communicates with the lower end of the first separation cavity; the outlet gas pipe communicates with the upper end of the first separation cavity; the outlet liquid pipe extends into the lower end of the second separation cavity and communicates with the second separation cavity.

[0005] In an embodiment of the present invention, the dispensing main body includes a base body and a cover plate. The base body is provided with a cavity, and the cover plate is installed on the upper end of the base body to close the cavity. In this way, it is beneficial to the assembly of the partition member and the dispensing main body.

[0006] In an embodiment of the present invention, both the outlet gas pipe and the outlet liquid pipe penetrate through the cover plate, and the inlet pipe penetrates through the bottom of the base body. Such a setting makes the connection of the outlet gas pipe, the outlet liquid pipe, and the inlet pipe to the dispensing main body simpler, improving the assembly efficiency of the dispenser.

[0007] In an embodiment of the present invention, the base body includes a bottom plate and side plates surrounding the edge of the bottom plate. The side plates are arranged on one side of the bottom plate. The wall thickness of the cover plate is greater than the wall thickness of the side plates, and the wall thickness of the cover plate is greater than the wall thickness of the bottom plate. Such a setting improves the connection strength between the outlet gas pipe and the cover plate and the connection strength between the outlet liquid pipe and the cover plate.

[0008] In an embodiment of the present invention, the partition member includes a connecting plate and a partition plate surrounding the edge of the connecting plate. The partition plate is arranged on one side of the connecting plate. The side of the connecting plate facing away from the partition plate is welded to the cover plate. The lower end of the partition plate is connected to the bottom wall of the cavity. The communication hole is arranged at one end of the partition plate away from the connecting plate. By providing the connecting plate on the partition member and welding between the connecting plate and the cover plate, the welding area between the partition member and the dispensing main body is increased, making the welding between the partition member and the dispensing main body more firm and improving the structural strength of the dispenser.

[0009] In an embodiment of the present invention, a plurality of communication holes are evenly distributed on the circumferential side of the partition plate. In this way, the refrigerant can be evenly diffused from the first separation chamber into the second separation chamber, which is beneficial for the distributor to achieve uniform distribution of the refrigerant.

[0010] In an embodiment of the present invention, the distribution main body is cylindrical, and the partition member is cylindrical. The partition member is coaxially arranged with the distribution main body to form an annular second separation chamber; the number of liquid outlet pipes is multiple, and the multiple liquid outlet pipes are evenly distributed in the second separation chamber. With such a setting, the refrigerant in the second separation chamber can enter the multiple liquid outlet pipes evenly, which is beneficial for the distributor to achieve uniform distribution of the refrigerant.

[0011] In an embodiment of the present invention, the distance between the end of the liquid outlet pipe extending into the second separation chamber and the bottom wall of the second separation chamber is h, and the distance between the communication hole and the bottom wall of the second separation chamber is d, satisfying h ≤ d. With such a setting, the gas-liquid separation effect of the distributor is further improved.

[0012] In an embodiment of the present invention, the distance that the gas outlet pipe protrudes from the inner wall of the first separation chamber is s, satisfying 5 mm ≤ s ≤ 20 mm; and / or, the distance that the inlet flow pipe protrudes from the inner wall of the first separation chamber is r, satisfying 5 mm ≤ r ≤ 20 mm. s ≥ 5 mm is beneficial for the assembly of the gas outlet pipe and the distribution main body, preventing the gas outlet pipe from detaching from the distribution main body. s ≤ 20 mm avoids the distance that the gas outlet pipe protrudes from the inner wall of the first separation chamber being too large, resulting in difficulty for the gaseous refrigerant medium to enter the gas outlet pipe. r ≥ 5 mm is beneficial for the assembly of the inlet flow pipe and the distribution main body, preventing the inlet flow pipe from detaching from the distribution main body. r ≤ 20 mm avoids the distance that the inlet flow pipe protrudes from the inner wall of the first separation chamber being too large, resulting in a large number of bubbles generated when the refrigerant medium flows out of the inlet flow pipe and impacts the bottom wall of the first separation chamber.

[0013] The present invention also provides an air-conditioning device, which includes a heat exchanger and the distributor described in any one of the above embodiments. The heat exchanger has a plurality of heat exchange pipes arranged in sequence from top to bottom. The gas outlet pipe is connected to the lowermost heat exchange pipe, and the liquid outlet pipe is connected to the other heat exchange pipes. With such a setting, the phenomenon of icing caused by the too low temperature of the lowermost heat exchange pipe can be avoided.

[0014] The dispenser and air conditioner provided by the present invention are such that since the air outlet pipe is connected to the upper end of the first separation chamber, gaseous refrigerant is discharged from the air outlet pipe out of the first separation chamber. Because the partition member is provided with a communication hole connecting the first separation chamber and the second separation chamber, liquid refrigerant flows from the first separation chamber through the communication hole to the second separation chamber. Since the liquid outlet pipe extends into the lower end of the second separation chamber, the liquid refrigerant flowing into the second separation chamber can be discharged through the liquid outlet pipe. The liquid refrigerant entering the second separation chamber may be mixed with a small amount of gaseous refrigerant, and the refrigerant can undergo gas-liquid separation again in the second separation chamber, with the gaseous refrigerant rising to the upper end of the second separation chamber. Since the liquid outlet pipe extends into the lower end of the second separation chamber, gaseous refrigerant will not escape from the liquid outlet pipe. As the gaseous refrigerant in the second separation chamber increases, the gas pressure in the second separation chamber gradually increases, thereby pressing the liquid refrigerant to be discharged from the liquid outlet pipe.

[0015] It can be seen that the refrigerant in a gas-liquid mixture undergoes gas-liquid separation twice in the dispenser, making the gas-liquid separation of the refrigerant more sufficient and greatly improving the gas-liquid separation effect of the dispenser. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or there may be an intermediate component at the same time.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] Please refer to Figure 1-2 , the present invention provides a dispenser, which includes a dispensing body 1, an inlet pipe 3, an outlet pipe 4 and an outlet gas pipe 5. The dispensing body 1 is provided with a cavity 11, and a partition 2 is arranged in the cavity 11. The partition 2 divides the cavity 11 into a first separation cavity 111 and a second separation cavity 112. The partition 2 is provided with a communication hole 21, and the communication hole 21 communicates the first separation cavity 111 and the second separation cavity 112, so that the liquid refrigerant enters the second separation cavity 112 from the first separation cavity 111 through the communication hole 21. The inlet pipe 3, the outlet pipe 4 and the outlet gas pipe 5 are all connected to the dispensing body 1, and the inlet pipe 3 communicates with the lower end of the first separation cavity 111. The outlet gas pipe 5 communicates with the upper end of the first separation cavity 111. The outlet pipe 4 extends into the lower end of the second separation cavity 112 and communicates with the second separation cavity 112.

[0025] For the dispenser and the air conditioning equipment provided by the present invention, since the outlet gas pipe 5 communicates with the upper end of the first separation cavity 111, therefore, the gaseous refrigerant is discharged from the first separation cavity 111 through the outlet gas pipe 5. Because the partition 2 is provided with the communication hole 21 that communicates the first separation cavity 111 and the second separation cavity 112, therefore, the liquid refrigerant flows from the first separation cavity 111 to the second separation cavity 112 through the communication hole 21. Since the outlet pipe 4 extends into the lower end of the second separation cavity 112, the liquid refrigerant flowing into the second separation cavity 112 can be discharged through the outlet pipe 4. The liquid refrigerant entering the second separation cavity 112 may be mixed with a small amount of gaseous refrigerant, and the refrigerant can be separated again into gas and liquid in the second separation cavity 112, and the gaseous refrigerant rises to the upper end of the second separation cavity 112. Since the outlet pipe 4 extends into the lower end of the second separation cavity 112, therefore, the gaseous refrigerant will not escape from the outlet pipe 4. As the gaseous refrigerant in the second separation cavity 112 increases, the gas pressure in the second separation cavity 112 gradually increases, thereby pressing the liquid refrigerant to be discharged through the outlet pipe 4.

[0026] It can be seen that the refrigerant in the gas-liquid mixture undergoes two gas-liquid separations in the distributor, making the gas-liquid separation of the refrigerant more thorough and greatly improving the gas-liquid separation effect of the distributor.

[0027] Specifically, as Figure 1-3 shown, the distribution body 1 is cylindrical, and the partition member 2 is cylindrical. The partition member 2 is coaxially arranged with the distribution body 1 to form an annular second separation chamber 112 and a columnar first separation chamber 111. In this way, it is beneficial to the processing and manufacturing of the distribution body 1 and the partition member 2. However, it is not limited to this. The distribution body 1 can also be non-circular cylindrical. For example, the cross-section of the distribution body 1 is square. Similarly, the partition member 2 can also be non-circular cylindrical. For example, the cross-section of the partition member 2 is square, and they will not be listed one by one here.

[0028] Furthermore, as Figure 1-3 shown, the number of liquid outlet pipes 4 is multiple, and the multiple liquid outlet pipes 4 are evenly distributed in the annular second separation chamber 112. With such a setting, the refrigerant in the second separation chamber 112 can enter the multiple liquid outlet pipes 4 evenly, which is beneficial for the distributor to achieve uniform distribution of the refrigerant. The number of liquid outlet pipes 4 can be 2, 3, 4, etc., and they will not be listed one by one here.

[0029] In one embodiment, as Figure 2 shown, the distribution body 1 includes a base body 13 and a cover plate 12. The base body 13 is provided with a cavity 11, and the cover plate 12 is installed at the upper end of the base body 13 to close the cavity 11. In this way, it is beneficial to the assembly of the partition member 2 and the distribution body 1. Specifically, the partition member 2 includes a connecting plate 22 and a partition plate 23 surrounding the edge of the connecting plate 22. The partition plate 23 is arranged on one side of the connecting plate 22. The side of the connecting plate 22 facing away from the partition plate 23 is welded to the cover plate 12, and the lower end of the partition plate 23 is connected to the bottom wall of the cavity 11. The communication hole 21 is arranged at one end of the partition plate 23 away from the connecting plate 22. At this time, first weld the connecting plate 22 of the partition member 2 to the cover plate 12, and then cover the cover plate 12 welded with the partition member 2 on the upper end of the base body 13 to close the cavity 11. Further, the cover plate 12 and the base body 13 can be welded together. By providing the connecting plate 22 on the partition member 2 and welding between the connecting plate 22 and the cover plate 12, the welding area between the partition member 2 and the distribution body 1 is increased, making the welding between the partition member 2 and the distribution body 1 more firm and improving the structural strength of the distributor.

[0030] In one embodiment, as Figure 2As shown, the air outlet pipe 5 and the liquid outlet pipe 4 both penetrate through the cover plate 12, and the inlet flow pipe 3 penetrates through the bottom of the base body 13. With such a setting, the connection of the air outlet pipe 5, the liquid outlet pipe 4, and the inlet flow pipe 3 to the distribution body 1 is made simpler, improving the assembly efficiency of the dispenser. Specifically, the cover plate 12 is provided with first assembly holes (not shown in the figure) for assembling the air outlet pipe 5 and the liquid outlet pipe 4. The air outlet pipe 5 and the liquid outlet pipe 4 are installed on the cover plate 12 through the first assembly holes, and both the air outlet pipe 5 and the liquid outlet pipe 4 are welded to the cover plate 12. The bottom of the base body 13 is provided with second assembly holes, the inlet flow pipe 3 is installed in the second assembly holes, and the inlet flow pipe 3 is welded to the base body 13.

[0031] In one embodiment, as Figure 2 shown, the base body 13 includes a bottom plate 131 and side plates 132 surrounding the edge of the bottom plate 131. The side plates 132 are arranged on one side of the bottom plate 131. The wall thickness of the cover plate 12 is greater than the wall thickness of the side plates 132, and the wall thickness of the cover plate 12 is greater than the wall thickness of the bottom plate 131. Since the air outlet pipe 5 penetrates through the cover plate 12, therefore, the wall thickness of the cover plate 12 is greater than the wall thickness of the side plates 132, which can increase the connection area between the air outlet pipe 5 and the cover plate 12 and improve the connection strength between the air outlet pipe 5 and the cover plate 12. Similarly, since the liquid outlet pipe 4 penetrates through the cover plate 12, therefore, the wall thickness of the cover plate 12 is greater than the wall thickness of the side plates 132, which can increase the connection area between the liquid outlet pipe 4 and the cover plate 12 and improve the connection strength between the liquid outlet pipe 4 and the cover plate 12.

[0032] In one embodiment, as Figure 2 shown, a plurality of communication holes 21 are evenly distributed around the circumference of the partition plate 23. In this way, the refrigerant can be evenly diffused from the first separation chamber 111 into the second separation chamber 112, which is beneficial for the dispenser to achieve uniform distribution of the refrigerant. In this embodiment, four communication holes 21 are evenly distributed around the circumference of the partition plate 23. In other embodiments, the number of communication holes 21 can also be 2, 3, or 5, etc., which will not be listed one by one here. Further, the communication holes 21 can be round holes, square holes, or holes of other shapes, which will not be listed one by one here.

[0033] In one embodiment, as Figure 2As shown in the figure, the distance between the end of the liquid outlet pipe 4 extending into the second separation chamber 112 and the bottom wall of the second separation chamber 112 is h, and the distance between the communication hole 21 and the bottom wall of the second separation chamber 112 is d, satisfying h ≤ d. When the refrigerant enters the second separation chamber 112 from the first separation chamber 111, the gas in the refrigerant starts to rise at the communication hole 21 of the second separation chamber 112, and the height of the port of the liquid outlet pipe 4 facing the bottom wall of the second separation chamber 112 is lower than the height of the communication hole 21, so that the gas in the refrigerant cannot enter the liquid outlet pipe 4 through the port of the liquid outlet pipe 4 facing the bottom wall of the second separation chamber 112. Thereby further improving the gas-liquid separation effect of the distributor. Specifically, d ≥ 5mm. Since the height of the port of the liquid outlet pipe 4 facing the bottom wall of the second separation chamber 112 is lower than the height of the communication hole 21, d ≥ 5mm can prevent the setting position of the communication hole 21 from being too low, resulting in the distance between the port of the liquid outlet pipe 4 facing the bottom wall of the second separation chamber 112 and the bottom wall of the second separation chamber 112 being too close, which affects the smooth entry of the liquid refrigerant into the liquid outlet pipe 4. Further, the port of the liquid outlet pipe 4 facing the bottom wall of the second separation chamber 112 is inclined, so that it is beneficial for the liquid refrigerant to quickly enter the liquid outlet pipe 4 and improve the distribution efficiency of the distributor.

[0034] In an embodiment, as Figure 2 shown, the distance that the gas outlet pipe 5 protrudes from the top wall of the first separation chamber 111 is s, satisfying 5mm ≤ s ≤ 20mm. s ≥ 5mm is beneficial for the assembly of the gas outlet pipe 5 and the distribution main body 1, and prevents the gas outlet pipe 5 from detaching from the distribution main body 1. s ≤ 20mm avoids the distance that the gas outlet pipe 5 protrudes from the top wall of the first separation chamber 111 being too large, resulting in difficulty for the gaseous refrigerant medium to enter the gas outlet pipe 5.

[0035] In an embodiment, as Figure 2 shown, the distance that the inlet flow pipe 3 protrudes from the bottom wall of the first separation chamber 111 is r, satisfying 5mm ≤ r ≤ 20mm. r ≥ 5mm is beneficial for the assembly of the inlet flow pipe 3 and the distribution main body 1, and prevents the inlet flow pipe 3 from detaching from the distribution main body 1. r ≤ 20mm avoids the distance that the inlet flow pipe 3 protrudes from the bottom wall of the first separation chamber 111 being too large, resulting in a large amount of bubbles generated when the refrigerant medium flows out of the inlet flow pipe 3 and impacts the bottom wall of the first separation chamber 111.

[0036] In an embodiment, the distributor is a copper alloy part. Specifically, the inlet flow pipe 3, the liquid outlet pipe 4, and the gas outlet pipe 5 are red copper parts, and the distribution main body 1 and the partition part 2 are brass parts. The brass parts have a greater hardness, and the distribution main body 1 and the partition part 2 are not easily deformed during assembly, improving the structural strength of the distributor. Usually, the pipe fittings in the air conditioning equipment are all red copper pipes. The inlet flow pipe 3, the liquid outlet pipe 4, and the gas outlet pipe 5 being red copper parts are beneficial for the assembly and welding of the inlet flow pipe 3, the liquid outlet pipe 4, and the gas outlet pipe 5 with other pipe fittings in the air conditioning equipment.

[0037] Please refer to Figure 1 、Figure 2 and Figure 4 , the present invention further provides an air conditioning device, which includes a heat exchanger and the distributor described in any one of the above embodiments. The heat exchanger has a plurality of heat exchange tubes 6 arranged in sequence from top to bottom. The air outlet pipe 5 is connected to the lowermost heat exchange tube 6, and the liquid outlet pipe 4 is connected to the other heat exchange tubes 6. Generally, water vapor in the air will condense on the heat exchanger, and the condensed water flows from the upper end of the heat exchanger to the lower end. When the condensed water flows to the lowermost end of the heat exchanger, icing may occur due to the too low temperature. Moreover, the heat absorption efficiency of the gaseous refrigerant in the air outlet pipe 5 is relatively low. Therefore, connecting the air outlet pipe 5 to the lowermost heat exchange tube 6 can prevent the temperature of the lowermost heat exchange tube 6 from being too low and causing icing.

[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0039] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as it is within the scope of the spirit of the present invention, appropriate changes and variations made to the above embodiments fall within the scope of protection required by the present invention.
