Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration technology, and in particular to a gas collecting pipe assembly and its refrigeration system. Background Technology
[0002] The manifold assembly is a commonly used structural component in refrigeration systems, used to distribute refrigerant. The manifold assembly typically includes a main pipe, a manifold, and branch pipes. The main pipe and the manifold are connected, and the branch pipes, which are multiple in number, are also connected to the manifold. The refrigerant in the main pipe is distributed to each branch pipe through the manifold.
[0003] Currently, each branch pipe of the gas collection pipe assembly needs to be welded to the gas collection pipe, resulting in a relatively concentrated weld point. This concentrated weld point can easily reduce the structural strength of the gas collection pipe. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a gas collection pipe assembly.
[0005] A gas collection pipe assembly includes: a main pipe; a gas collection pipe connected to the main pipe, wherein the gas collection pipe has a first connecting port and a second connecting port; a first branch pipe connected to the first connecting port, wherein the end of the first branch pipe away from the gas collection pipe has at least two first connecting pipes; and a second branch pipe connected to the second connecting port, wherein the end of the second branch pipe away from the gas collection pipe has at least two second connecting pipes.
[0006] This configuration allows the main pipe to input refrigerant into the manifold, which then distributes the refrigerant to the first and second branch pipes via the first and second connecting ports. The first branch pipe has at least two first connecting pipes, and the second branch pipe has two second connecting pipes. Therefore, the manifold can output refrigerant to at least four branch lines through just two welded joints on the first and second branch pipes. This reduces the number of welded joints, thus preventing refrigerant leakage, simplifying sealing, and preventing multiple welded joints from affecting the structural strength of the manifold. It also eliminates obstructions at connections, reduces turbulence caused by numerous connecting ports on the manifold, and allows for smoother airflow. The simplified structure reduces maintenance difficulty and costs, and the integrated design is more compact, saving installation space.
[0007] In one embodiment, the two first connecting pipes and the first branch pipe are integrally formed; and / or, the two second connecting pipes and the second branch pipe are integrally formed.
[0008] In one embodiment, the end of the first branch pipe away from the first connecting port is connected to a first tee pipe, one of the passages of the first tee pipe is connected to the first branch pipe, and the other two passages respectively form two first connecting pipes.
[0009] In one embodiment, the end of the second branch pipe away from the second connecting port is connected to a second tee pipe, one of the passages of the second tee pipe is connected to the second branch pipe, and the other two passages respectively form two second connecting pipes.
[0010] In one embodiment, the gas collecting pipe is provided with a first connecting pipe and a second connecting pipe, the first connecting pipe being connected to the gas collecting pipe to form a first connecting port, and the second connecting pipe being connected to the gas collecting pipe to form a second connecting port.
[0011] In one embodiment, the first connector is located at the end of the gas collecting pipe along its length, and the second connector is located on the outer periphery of the gas collecting pipe in the radial direction; and / or, both the first connector and the second connector are located at the same end of the gas collecting pipe along its length.
[0012] In one embodiment, the inner diameters of the first and second connecting pipes are set to be the same, the outer peripheral wall of the first branch pipe is connected to the inner wall of the first connecting pipe, and the outer peripheral wall of the second branch pipe is connected to the inner wall of the second connecting pipe.
[0013] In one embodiment, both first connecting pipes extend in a direction away from the gas collecting pipe and are arranged parallel and spaced apart; both second connecting pipes extend in a direction away from the second connecting port and are arranged parallel and spaced apart.
[0014] In one embodiment, the end of the first connecting pipe near the first connecting port is configured as an arc-shaped pipe structure; and / or, the end of the second connecting pipe near the second connecting port is configured as an arc-shaped pipe structure.
[0015] This utility model also provides a refrigeration system, including the gas collection pipe assembly as described above.
[0016] Compared with the prior art, this utility model provides at least two first connecting pipes and at least two second connecting pipes at the ends of the first and second branch pipes connected to the gas collecting pipe. Therefore, the gas collecting pipe only needs two pipe welding points to achieve the connection of four pipes, reducing the number of welding points in the gas collecting pipe and lowering the risk of leakage.

[0028] Please see Figures 1-4 This utility model provides a gas collecting pipe assembly 100, in which the gas collecting pipe 20 is connected to the first branch pipe 30 and the second branch pipe 40. At least two first connecting pipes 31 and at least two second connecting pipes 41 are provided at the ends of the first branch pipe 30 and the second branch pipe 40 away from the gas collecting pipe 20. Therefore, the gas collecting pipe 20 only needs two pipe welding points to achieve the connection of four pipes, reducing the number of welding points of the gas collecting pipe 20 and reducing the risk of leakage.
[0029] The gas collecting pipe assembly 100 includes a main pipe 10, a gas collecting pipe 20, a first branch pipe 30, and a second branch pipe 40. The gas collecting pipe 20 is connected to the main pipe 10 and has a first connecting port and a second connecting port. The first branch pipe 30 is connected to the first connecting port and has at least two first connecting pipes 31 at the end of the first branch pipe 30 away from the gas collecting pipe 20. The second branch pipe 40 is connected to the second connecting port and has at least two second connecting pipes 41 at the end of the second branch pipe 40 away from the gas collecting pipe 20.
[0030] Thus, the main pipe 10 is used to input refrigerant into the gas collecting pipe 20. The gas collecting pipe 20 then distributes the refrigerant to the first branch pipe 30 and the second branch pipe 40 through the first connecting port and the second connecting port. The first branch pipe 30 has at least two first connecting pipes 31, and the second branch pipe 40 has two second connecting pipes 41. Therefore, the gas collecting pipe 20 can output refrigerant to at least four branches through the two weld points of the first branch pipe 30 and the second branch pipe 40, reducing the number of welding points, thereby avoiding refrigerant leakage, reducing sealing difficulty, and preventing the concentration of welding points from affecting structural strength. It can also eliminate obstructions at the connection points, reduce turbulence caused by the large number of connecting ports on the gas collecting pipe 20, and make the airflow smoother. The structure is simplified, the maintenance difficulty and cost are reduced, and the space occupied is more compact, saving installation space.
[0031] Furthermore, the two first connecting pipes 31 and the first branch pipe 30 are integrally formed; and / or, the two second connecting pipes 41 and the second branch pipe 40 are integrally formed. In this way, the first connecting pipe 31 and the first branch pipe 30 are integrally formed, and the second connecting pipe 41 and the second branch pipe 40 are integrally formed, resulting in better overall structural integrity, stronger impact resistance, better durability, simpler installation, and savings in time and manpower.
[0032] Understandably, in other embodiments, a split installation may also be adopted. For example, the end of the first branch pipe 30 furthest from the first connecting port is connected to a first tee pipe 32. One passage of the first tee pipe 32 is connected to the first branch pipe 30, and the other two passages form two first connecting pipes 31. The end of the second branch pipe 40 furthest from the second connecting port is connected to a second tee pipe 42. One passage of the second tee pipe 42 is connected to the second branch pipe 40, and the other two passages form two second connecting pipes 41. Thus, the first connecting pipes 31 and the second connecting pipes 41 are formed through the first tee pipe 32 and the second tee pipe 42, respectively. The first tee pipe 32 has three passages, one of which is used to connect to the first branch pipe 30, and the other two form two first connecting pipes 31. Similarly, the second tee pipe 42 is also connected to the second branch pipe through one connecting passage, and the two connecting pipes furthest from the second branch pipe form second connecting pipes 41.
[0033] In other embodiments, the tee pipe can also be replaced with a four-way pipe or other structures, and is not limited to the form of a tee pipe.
[0034] Furthermore, the gas collecting pipe 20 is constructed with a first connecting pipe 21 and a second connecting pipe 22. The first connecting pipe 21 connects to the gas collecting pipe 20 to form a first connecting port, and the second connecting pipe 22 connects to the gas collecting pipe 20 to form a second connecting port. In this way, the gas collecting pipe 20 is connected to the first branch pipe 30 through the first connecting pipe 21 and to the second branch pipe 40 through the second connecting pipe 22. The connection strength is higher, the contact area is larger, making the installation more stable, simplifying the assembly process, reducing welding difficulty, and reducing the risk of leakage.
[0035] The inner diameters of the first connecting pipe 21 and the second connecting pipe 22 are set to be the same. The outer peripheral wall of the first branch pipe 30 is connected to the inner wall of the first connecting pipe 21, and the outer peripheral wall of the second branch pipe 40 is connected to the inner wall of the second connecting pipe 22. In this way, the inner diameters of the first connecting pipe 21 and the second connecting pipe 22 are the same, the refrigerant flow is more even, and the first branch pipe 30 is embedded in the first connecting pipe 21, and the second branch pipe 40 is embedded in the second connecting pipe 22, which facilitates installation.
[0036] For example, please see Figures 1-4 ,exist Figure 1 Example 1 and Figure 2 In Embodiment 2, the first connecting pipe 21 is located at the same end along the length of the gas collecting pipe 20, and the second connecting pipe 22 is located on the outer periphery of the gas collecting pipe 20 in the radial direction. In Embodiment 1, the first connecting pipe 31 and the first branch pipe 30 are integrally formed, as are the second connecting pipe 41 and the second branch pipe 40. In Embodiment 2, the end of the first branch pipe 30 is provided with a first tee pipe 32 to achieve multiple outlets, and the end of the second branch pipe 40 is provided with a second tee pipe 42 to achieve multiple outlets. Figure 3 Example 3 and Figure 4 In Embodiment 4, both the first connecting pipe 21 and the second connecting pipe 22 are located at the ends of the gas collecting pipe 20 along its length. In Embodiment 3, the first connecting pipe 31 and the first branch pipe 30 are integrally formed, as are the second connecting pipe 41 and the second branch pipe 40. In Embodiment 4, the end of the first branch pipe 30 is equipped with a first tee pipe 32 to achieve multiple outlets, and the end of the second branch pipe 40 is equipped with a second tee pipe 42 to achieve multiple outlets. This also helps to balance the pressure within the gas collecting pipe 20, resulting in more uniform gas distribution. Maintenance and management are simplified, reducing maintenance costs and difficulty, and minimizing space occupation.
[0037] Specifically, both first connecting pipes 31 extend away from the gas collecting pipe 20 and are arranged in parallel at intervals; both second connecting pipes 41 extend away from the second connecting port and are arranged in parallel at intervals. This facilitates processing and makes it easy to connect and assemble with other pipelines.
[0038] Preferably, the end of the first connecting pipe 31 near the first connecting port is configured as an arc-shaped pipe structure; and / or, the end of the second connecting pipe 41 near the second connecting port is configured as an arc-shaped pipe structure. The arc-shaped pipe structure can guide the flow direction of the refrigerant, making the refrigerant turn more smoothly and reducing refrigerant turbulence, thereby making the refrigerant flow more smoothly.
[0039] This utility model also provides a refrigeration system, including the gas collection pipe assembly 100 as described above.
[0040] Compared with the prior art, this utility model provides at least two first connecting pipes 31 and at least two second connecting pipes 41 at the ends of the first branch pipe 30 and the second branch pipe 40 connected to the gas collecting pipe 20. Therefore, the gas collecting pipe 20 only needs two pipe welding points to achieve the connection of four pipes, reducing the number of welding points of the gas collecting pipe 20 and reducing the risk of leakage.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
