[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art of this application. In this specification, the terms used in this application are only for the purpose of describing specific embodiments and are not intended to limit this application. As used herein, the term "and / or" includes one or more of any and all combinations of the associated items.

[0022] 1 and 2, the present application provides an air collecting pipe assembly including a main air collecting pipe 1, an air collecting branch pipe 4, and a branch pipe body 2 connected to one end of the main air collecting pipe 1 and provided with a plurality of pipe connection ports 3, the plurality of air collecting branch pipes 4 being connected to the plurality of pipe connection ports 3. Usually, the fluid medium enters the branch pipe body 2 from the plurality of air collecting branch pipes 4 through the pipe connection ports 3, and then enters the main air collecting pipe 1 from the branch pipe body 2, thereby realizing collection of the fluid medium. In other cases, the fluid medium can also be divided by entering the plurality of air collecting branch pipes 4 from the main air collecting pipe 1 through the branch pipe body 2. In this embodiment, the inner diameter of the branch pipe body 2 is larger than the inner diameter of the main air collecting pipe 1. With such a configuration, the mounting area of ​​the branch pipe body 2 can be increased, and the mounting of the air collecting branch pipe 4 to the branch pipe body 2 is advantageous. In addition, the branch pipe body 2 and the main air collecting pipe 1 are integrally molded, and integrally molded refers to the branch pipe body 2 and the main air collecting pipe 1 being processed and molded at one time, that is, the branch pipe body 2 and the main air collecting pipe 1 are not processed separately and then connected. As a result, there is no connection gap between the branch pipe body 2 and the main air collecting pipe 1, and the problem of leakage occurring when the fluid medium flows between the branch pipe body 2 and the main air collecting pipe 1 is eliminated. As can be seen from the above, the air collecting pipe assembly provided by the present application solves the problem that there is a risk of leakage in the air collecting pipe assembly.

[0023] In one embodiment, the main air collecting pipe 1 is formed into the branch pipe body 2 by spinning, and the wall thickness of the branch pipe body 2 is smaller than that of the main air collecting pipe 1. The spinning process is performed by fixing the main air collecting pipe 1 to the mold of a spinning machine and rotating it together with the main shaft of the machine tool, while pressing the main air collecting pipe 1 with a roller or spatula to partially plastically deform the main air collecting pipe 1. In this embodiment, after the side wall of the main air collecting pipe 1 is deformed by spinning, the inner diameter is enlarged and the wall thickness is thinned to form the branch pipe body 2. The spinning process is a mature process and has high processing efficiency, so that the processing efficiency of the entire air collecting pipe assembly can be improved, and the branch pipe body 2 processed by spinning has higher precision.

[0024] In another embodiment, the main air collecting pipe 1 is cold pressed to form the branch pipe body 2, and the wall thickness of the branch pipe body 2 is equal to that of the main air collecting pipe 1. Cold pressing is a pressure processing method in which a press die is used to apply pressure to the main air collecting pipe 1 on a press machine at room temperature to plastically deform the main air collecting pipe 1. In this embodiment, after the side wall of the main air collecting pipe 1 is deformed by cold pressing, the inner diameter of the main air collecting pipe 1 is enlarged and the total length is shortened to form the branch pipe body 2, and the wall thickness of the formed branch pipe body 2 is equal to that of the main air collecting pipe 1. This configuration makes the structure of the branch pipe body 2 more robust, and the branch pipe body 2 is less likely to deform even when it is impacted during the use of the air collecting pipe assembly, thereby improving the service life of the air collecting pipe assembly.

[0025] In one embodiment, the pipe connection port 3 and the branch pipe body 2 are integrally molded. With this configuration, there is no connection gap between the branch pipe body 2 and the pipe connection port 3, and the problem of leakage occurring when the fluid medium flows between the branch pipe body 2 and the pipe connection port 3 is eliminated. This greatly improves the sealing of the entire air collection pipe assembly.

[0026] 1 and 2, in one embodiment, the pipe connection port 3 includes a first connection port 31 provided at one end of the branch pipe body 2 remote from the main air collecting pipe 1, and a second connection port 32 provided on a side wall of the branch pipe body 2. This allows more freedom in the installation position of the pipe connection port 3, and since the air collecting branch pipe 4 and the branch pipe body 2 are connected by the pipe connection port 3, the installation position of the air collecting branch pipe 4 is also more free, which is advantageous in freely setting the relative positions of the main air collecting pipe 1 and the air collecting branch pipe 4 in the air collecting pipe assembly according to actual needs.

[0027] In one embodiment, as shown in Figs. 1 and 2, the second connection port 32 is formed by opening a hole in the side wall of the branch pipe body 2 and flanging the opening portion. Specifically, it is necessary to first open a hole in the side wall of the branch pipe body 2, and then the side wall of the branch pipe body 2 in the opening region is flanged outward to form the second connection port 32. With this configuration, the processing method of the second connection port 32 becomes simple, and the connection between the second connection port 32 and the branch pipe body 2 becomes more robust. However, the present invention is not limited to this, and the second connection port 32 may be formed by flanging the side wall of the branch pipe body 2 in the opening region inward.

[0028] In one embodiment, as shown in Figures 1 to 2, the branch pipe body 2 and the main air collecting pipe 1 are connected by a cone-shaped transition structure, and the inclination angle of the outer surface of the cone-shaped transition structure is less than 45°, which makes the connection between the branch pipe body 2 and the main air collecting pipe 1 smoother.

[0029] 1 and 2, there are a plurality of first connection ports 31. The first connection port 31 is provided at one end of the branch pipe body 2 away from the main air collection pipe 1, so that a plurality of first connection ports 31 can be provided at the end of the branch pipe body 2, which is advantageous for connecting more air collection branch pipes 4 to the end of the branch pipe body 2.

[0030] 1 and 2, in one embodiment, there are a plurality of second connection ports 32. Since the second connection ports 32 are provided on the side wall of the branch pipe body 2, a plurality of second connection ports 32 can be provided on the side wall of the branch pipe body 2, which is advantageous for connecting more air collection branch pipes 4 to the side wall of the branch pipe body 2.

[0031] 1 and 2, the air collection pipe assembly further includes a plurality of air collection branch pipes 4, which are connected to a corresponding plurality of pipe connection ports 3, and the air collection branch pipe 4 includes a first branch pipe 41, which is inserted into the first connection port 31, and a first positioning protrusion (not shown) is provided on the inner wall of the first connection port 31, and the first branch pipe 41 is abutted against the first positioning protrusion. With this configuration, the insertion depth of the first branch pipe 41 into the first connection port 31 can be limited by the first positioning protrusion, thereby improving the assembly accuracy of the first branch pipe 41 and the branch pipe body 2.

[0032] 1 and 2, in one embodiment, the air collection branch pipe 4 includes a second branch pipe 42, which is inserted into the second connection port 32, and a second positioning protrusion is provided on the outer wall of the second branch pipe 42, and the second connection port 32 is abutted against the second positioning protrusion. With this configuration, the insertion depth of the second branch pipe 42 into the second connection port 32 can be limited by the second positioning protrusion, thereby improving the assembly accuracy of the second branch pipe 42 and the branch pipe body 2.

[0033] The present application further provides an air conditioning device including an air collection duct assembly according to any of the above embodiments.

[0034] Each of the technical features of the above-mentioned embodiments may be combined in any combination. For the sake of brevity, not all possible combinations of each of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, all of them should be considered within the scope described in this specification.
