Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a pipe assembly and a refrigeration system. Background Technology

[0002] Currently, during the assembly of refrigeration systems, the narrow space between the equipment necessitates the manual binding of counterweights to the pipes to reduce vibration. Due to the large number of pipes, there are relatively many locations where counterweights need to be placed, resulting in longer assembly time and impacting overall assembly efficiency.

[0003] Therefore, how to improve assembly efficiency has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] This application proposes a tube assembly and a refrigeration system to improve assembly efficiency.

[0005] To achieve the above objectives, this application discloses the following technical solutions:

The pipe includes a first interface segment, a second interface segment, and a connecting segment connecting the first interface segment and the second interface segment. The counterweight is welded to the outer periphery of the connecting segment and includes at least one counterweight unit arranged side by side.

[0007] In some embodiments, the counterweight unit and the connecting section are arranged concentrically or eccentrically.

[0008] In some embodiments, the exterior of the counterweight unit is welded to the outer periphery of the connecting section.

[0009] In some embodiments, the surface where the counterweight unit and the connecting section are in contact is a curved surface, a straight line, or a curve.

[0011] In some embodiments, the counterweight unit includes a housing.

[0012] In some embodiments, the counterweight unit also includes filler material that is filled inside the housing.

[0013] In some embodiments, the filler is a solid or a liquid.

[0014] In some embodiments, the filler includes any one or at least two of stainless steel balls, carbon steel balls, sand, iron powder, and lime powder.

[0015] In some embodiments, the housing includes a fitting portion and a bulge portion that fit into the connecting segment, the bulge portion and the fitting portion being closedly connected, and the fitting portion being welded to the connecting segment.

[0016] In some embodiments, the bulge is a planar structure or a curved structure.

[0017] In some embodiments, the bulge has a cylindrical or spherical structure.

[0018] In some embodiments, the fitting portion is sleeved on the outer periphery of the connecting segment; or the fitting portion is located on one side of the connecting segment.

[0019] In some embodiments, the counterweight unit includes at least two counterweight plates arranged in a stacked manner.

[0020] In some embodiments, the outer surfaces of the connecting section and the counterweight unit are provided with an anti-rust coating.

[0021] In some embodiments, the counterweight unit includes a water-guiding surface.

[0022] In some embodiments, the welds of the counterweight units and the connecting sections are arranged at an angle.

[0023] In some embodiments, the counterweight unit is made of stainless steel or carbon steel.

[0024] In some embodiments, a copper film is attached to the outer periphery of the first interface segment and the second interface segment, and the welding temperature of the first interface segment and the second interface segment to the copper film is equal to the welding temperature of the counterweight unit to the connecting segment.

[0026] As can be seen from the above technical solution, since the counterweight is welded to the connecting section, no additional binding operation is required when assembling the pipe assembly onto the compressor, reducing assembly process steps and thus improving assembly efficiency. Furthermore, since the welding process between the counterweight and the pipe is not limited by assembly space, automation is easily achieved. Finally, since the counterweight consists of at least one counterweight unit, the number of counterweight units can be adjusted according to requirements, reducing processing costs.

[0059] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.

[0060] See Figure 1 This application provides a pipe assembly 10, including a pipe 1 and a counterweight 2. The pipe 1 includes a first interface segment 11, a second interface segment 12, and a connecting segment 13 connecting the first interface segment 11 and the second interface segment 12. The counterweight 2 is welded to the outer periphery of the connecting segment 13. As can be seen from the above technical solution, since the counterweight 2 is welded to the connecting segment 13, the pipe assembly 10 does not require additional binding operations when assembled onto the compressor, reducing assembly process steps and thus improving assembly efficiency. Furthermore, since the welding process between the counterweight 2 and the pipe 1 is not limited by assembly space, automation is easily achieved.

[0061] The first interface segment 11 and the second interface segment 12 mentioned above enable the connection between pipe 1 and the corresponding equipment, such as the connection between the compressor and the liquid storage tank, or the connection between the compressor and the four-way valve. The first interface segment 11 and the second interface segment 12 are formed at both ends of the connecting segment 13, which can be a straight pipe 1, a bent pipe 1, a special-shaped pipe 1, etc.

[0062] See Figures 2 to 7 , Figure 2 Connecting section 13 is straight pipe 1. Figures 3 to 7 The connecting segment 13 shown includes at least one bend. Figure 3 Includes a bend. Figure 4 Includes three bends. Figure 5 Includes two bends, Figures 3 to 6 The angle α of the middle bend is 90°. Figure 7 The angle α of the bend is 30°. The number of bends and the angle α can be adjusted according to the space requirements of pipe 1 in adjacent equipment. The angle of the bend can be understood as the included angle between the two sides of the pipe 1 body.

[0063] The counterweight 2 is placed at the bend or other part of the connecting section 13. Its specific placement needs to be determined according to the position of the pipe 1 in the adjacent equipment. Figures 2 to 5 as well as Figure 7 In the middle, counterweight 2 is arranged in the area of ​​straight pipe 1 in connecting section 13. Figure 6 In the middle, counterweight 2 is arranged in the bending part.

[0064] The counterweight 2 can be sleeved onto the connecting section 13 before being welded to it. The counterweight 2 includes at least one counterweight unit 2a, which are arranged side by side, such as... Figure 8 As shown. Since the counterweight component consists of at least one counterweight unit, the number of counterweight units can be adjusted according to requirements, reducing processing costs. Each counterweight component 2 may include one counterweight unit 2a, or may include two, three, four, or even more counterweight units 2a. The number of counterweight units 2a can be adjusted according to the counterweight requirements of the installation location.

[0065] See Figure 9a and Figure 10a In the diagram, the counterweight unit 2a is a solid structure and is fitted around the outer periphery of the connecting section 13. By fitting it around the connecting section 13, stable contact between the counterweight unit 2a and the connecting section 13 can be achieved during welding without the need for additional tooling, thus reducing the positioning difficulty during welding. Furthermore, in some examples, the counterweight unit 2a may include at least one counterweight sleeve 21, such as... Figure 9b and Figure 9c As shown. The counterweight sleeve 21 has a cylindrical structure and can be arranged concentrically with the connecting section 13 for easy assembly, as shown. Figure 9b As shown; the counterweight sleeve 21 is a cylinder with a notch, which can be arranged concentrically with the connecting section 13. Because the counterweight sleeve 21 has a notch, the center of gravity of the counterweight unit 2a shifts, as shown. Figure 9c As shown. In some examples, the counterweight unit 2a may include at least two counterweight sleeves 21, such as... Figure 10b and Figure 10c As shown in the figure, the counterweight sleeve 21 can be arranged concentrically with the connecting section 13 for easy assembly. The number of counterweight sleeves 21 in the figure is three, but in other examples of this application, there may be two, four, etc. Figure 10b The middle counterweight sleeve 21 has a cylindrical structure; Figure 10c The middle counterweight sleeve 21 is a cylinder with a notch; Figure 10d The middle counterweight 2a includes a counterweight sleeve 21 and a counterweight piece 22 arranged on the outer periphery of the counterweight sleeve.

[0066] See Figure 11 The counterweight unit 2a has a solid structure, such as Figure 12a As shown, the counterweight unit 2a can also be a hollow structure, such as... Figures 12b to 12d As shown, the counterweight unit 2a described in the figure may include a housing 23, and the housing 23 may form a cavity 24 together with the outer periphery of the connecting section 13, such as... Figure 12b As shown; or the shell 23 itself forms a cavity 24, such as Figure 12c As shown, the housing 23 may include a fitting portion 231 and a bulge portion 232 that fit together with the connecting segment 13. The bulge portion 232 and the fitting portion 231 are closedly connected, and the fitting portion 231 is welded to the connecting segment 13.

[0067] For example, the fitting portion 231, which is fitted onto the outer periphery of the connecting section 13, can be a cylindrical structure, such as... Figure 12c and Figure 12d As shown. The bulge 232 has a planar structure or a curved structure, such as a semi-cylindrical structure, a cylindrical structure, or a spherical structure. Figure 12b and Figure 12c It is a cylindrical structure. Figure 12d It has a semi-cylindrical structure.

[0068] Of course, the bulge 232 can also have other structures, see 13. In the figure, part of the bulge 232 is a cylindrical structure and the other part is a cuboid structure.

[0069] To increase the weight of the counterweight unit 2a, the counterweight unit 2a also includes a filler 3 inside the housing 23, such as... Figures 14c to 14f The filler 3 can be solid or liquid. When solid, it can be filled into the cavity 24 before welding the counterweight 2a to the connecting section 13. For example, the filler 3 includes any one or at least two of stainless steel balls, carbon steel balls, sand, iron powder, and lime powder. When liquid, it is filled into the cavity 24 after welding the counterweight 2a to the connecting section 13. For example, the filler 3 includes water. The amount of filler 3 can be determined according to the specific arrangement of the pipe 1. The amount of filler 3 can be more for areas with higher stress and less for areas with lower stress, or even none. This application does not make specific limitations. The ratio of the volume V1 of the filler 3 to the internal volume V2 of the shell 23 ranges from 0% to 100%, including endpoint values.

[0070] The shell 23 and the connecting section 13 are arranged concentrically, and the geometric center of the shell 23 coincides with the center of the connecting section 13. Figures 14a to 14f In the structure shown, the shell 23 and the connecting section 13 are arranged eccentrically, that is, the center of the shell 23 and the center of the connecting section 13 do not coincide. Figure 14b The outer periphery of the middle shell 23 and the connecting section 13 together form the cavity 24. Figure 14b The middle shell 23 includes a fitting portion 231 and a bulge portion 232, which together form a cavity 24. The fitting portion 231 has a cylindrical structure, a part of the bulge portion 232 is a cylindrical surface, and another part of the bulge portion 232 is a cubic column. The overall cross-section is U-shaped.

[0071] In addition, in order to fill the filler 3 as needed, the housing is also provided with a filling hole 25. After the filler is filled, the filling hole 25 is sealed. The sealing method can be welding or rubber plug.

[0072] Figure 14a and Figure 14b The middle cavity 24 was not filled with filler 3. Figures 14c to 14d It is filled with filler 3.

[0073] When the counterweight unit 2a includes a housing 23, the inner surface of the housing 23 is a smooth surface or is provided with protrusions.

[0074] In addition, considering the service life, the connection between the counterweight unit 2a and the connecting section 13 in this application is also designed to be waterproof. For example, the outer surfaces of the connecting section 13 and the counterweight unit 2a are coated with an anti-rust coating; the counterweight unit 2a includes a water-guiding surface; and the weld between the counterweight unit 2a and the connecting section 13 is arranged at an angle.

[0075] To further optimize the above scheme, the counterweight unit 2a is made of stainless steel or carbon steel, while the pipe 1 is made of stainless steel. In existing technologies, to reduce electrochemical corrosion at the interface between pipe 1 and the corresponding equipment, a copper film is typically attached to the outer periphery of the first interface section 11 and the second interface section 12 of pipe 1. Currently, the copper film is connected to the outer periphery of the first interface section 11 and the second interface section 12 using a welding process. Specifically, welding material is added between the copper film and the first interface section 11 and the second interface section 12, and furnace welding is employed.

[0076] To reduce the connection steps between the counterweight unit 2a and the pipe 1, the welding temperature of the first interface section 11 and the second interface section 12 to the copper film is equal to the welding temperature of the counterweight unit 2a to the connecting section 13. In other words, the welding temperature of the solder between the counterweight unit 2a and the connecting section 13 is equal to the welding temperature of the solder between the first interface section 11 and the second interface section 12 and the copper film. For example, silver-based solder, nickel-based solder, or alternative silver-based solder can be used.

[0077] Of course, in other examples of this application, the above welding can also be performed using argon arc welding, brazing, laser welding, etc.

[0078] The above examples in this application mainly describe the method of welding connection between the counterweight unit 2a and the connecting section 13. In some other examples of this application, the counterweight unit 2a can also be snapped with the connecting section 13 or the counterweight unit 2a and the connecting section 13 can also be an integral structure.

[0079] This application provides a refrigeration system including a compressor, an intake pipe 1, and an exhaust pipe 1. The intake pipe 1 is connected to the intake port of the compressor, and the exhaust pipe 1 is connected to the exhaust port of the compressor. At least one of the intake pipe 1 and / or the exhaust pipe 1 is a pipe assembly 10 as described above. Since the aforementioned pipe assembly 10 has the above-mentioned beneficial effects, including the corresponding effects of the refrigeration system with the pipe assembly 10, further details are omitted here.
