[0035] Combined with Figures 1 to 4 As shown, according to a specific embodiment of the present application, an automotive air-conditioning pipeline is provided.

[0036] The automotive air-conditioning pipeline includes a main pipe 1 and a sub-pipe 2. The main pipe 1 includes a main pipe body 11 and at least one first branch pipe 12 connected to the main pipe body 11; the sub-pipe 2 includes a sub-pipe body 21 and at least one second branch pipe 22 connected to the sub-pipe body 21. The main pipe body 11 and the sub-pipe body 21 are connected by at least one connecting piece, and the diameter of the main pipe 1 is set larger than that of the sub-pipe 2; wherein, at least one of the outlet end of the main pipe body 11, the outlet end of the sub-pipe body 21, the outlet end of the first branch pipe 12, and the outlet end of the second branch pipe 22 is provided with a connector 3.

[0037] Applying the technical solution of this embodiment, by setting the main pipe 1 including the main pipe body 11 and the first branch pipe 12, the sub-pipe 2 including the sub-pipe body 21 and the second branch pipe 22, and setting the connector 3 at the outlet end of each pipeline, the connection of multiple heat exchangers in the air-conditioning system is realized, and thus the independent or combined operation of multiple heat exchangers is achieved. Compared with the technical solution in the prior art that requires multiple pipelines to connect multiple components, the automotive air-conditioning pipeline in this solution effectively shortens the pipeline length, saves the layout space and reduces the installation difficulty, and solves the problems such as large installation difficulty, high cost, high weight, and long installation working hours caused by many pipes and long pipelines.

[0038] In the embodiment of the present application, the diameter of the main pipe 1 being larger than that of the sub-pipe 2 means that the diameter of the main pipe body 11 is larger than that of the sub-pipe body 21, and the diameter of the first branch pipe 12 is larger than that of the second branch pipe 22. Both the main pipe 1 and the sub-pipe 2 have a head, a branch, a middle part, and a tail. Among them, the branch refers to the first branch pipe 12 connected to the main pipe body 11 and the second branch pipe 22 connected to the sub-pipe body 21, and the head, middle part, and tail refer to the head, middle part, and tail of the main pipe body 11 and the sub-pipe body 21. Those skilled in the art should understand that the main pipe body 11 and the sub-pipe body 21 can be an integrated pipeline, or can be spliced or welded by multiple pipe segments.

[0039] It should be understood that according to actual needs, both the main pipe 1 and the sub-pipe 2 can include multiple branches, that is, can have multiple first branch pipes 12 and second branch pipes 22, and connectors 3 are set at the outlet ends of each branch to realize the connection of more heat exchangers in the air-conditioning system, reduce the number of pipeline layouts, and reduce the pipeline layout difficulty.

[0040] Furthermore, a temperature and pressure sensor 6 is provided at the tail of the main pipe body 11. By setting the temperature and pressure sensor 6, the changes in temperature and pressure can be monitored in real time, so as to make corresponding adjustments and controls in a timely manner, which is beneficial to preventing problems such as overheating and overpressure of the automotive air-conditioning, and helps to ensure the normal operation of the automotive air-conditioning and extend its service life.

[0041] In an exemplary embodiment of the present application, a connector 3 is provided at the tail outlet end of the main pipe body 11, and the temperature and pressure sensor 6 is disposed on the connector 3 at the tail outlet end of the main pipe body 11.

[0042] In an exemplary embodiment of the present application, a pressing plate 4 is provided at the tail outlet end of the main pipe body 11, and the temperature and pressure sensor 6 is disposed on the pressing plate 4.

[0043] Optionally, the connector 3 includes a triangular connector 31, and the outlet ends of the first branch pipe 12 and the second branch pipe 22 are connected to the same triangular connector 31. The triangular connector 31 can facilitate the adjustment of the pipeline angle, making the pipeline layout more flexible and convenient for assembly.

[0044] It should be noted that setting the connector 3 at the outlet end of the first branch pipe 12 and the connector 3 at the outlet end of the second branch pipe 22 as a whole can make the pipeline assembly more convenient. According to actual needs, the outlet end of the first branch pipe 12 and the outlet end of the second branch pipe 22 can also be respectively connected to a separate connector 3.

[0045] Optionally, the connector 3 includes a double O-ring connector 32, and double O-ring connectors 32 are provided at the head outlet end of the main pipe body 11, the tail outlet end of the main pipe body 11, the head outlet end of the auxiliary pipe body 21, and the tail outlet end of the auxiliary pipe body 21. Since the double O-ring connector 32 has two O-ring seals, it has a better sealing effect and is more wear-resistant, which can improve the sealing performance of the pipeline and extend the service life.

[0046] It should be noted that the connector 3 includes various connector structures such as a double O-ring connector, a single O-ring connector, a triple O-ring connector (as shown in Figure 3 ), a four-ring groove structure (as shown in Figure 4 ), etc. According to actual needs, any one of these connector structures can be selected for the automotive air-conditioning pipeline in this embodiment.

[0047] Furthermore, connectors 3 are respectively provided at the head outlet end of the main pipe body 11 and the head outlet end of the auxiliary pipe body 21. The first branch pipe 12 is one, and the first branch pipe 12 is connected to the head of the main pipe body 11. There is a distance H1 between the connection position of the main pipe body 11 and the first branch pipe 12 and the connector 3 provided at the outlet end of the first branch pipe 12; the second branch pipe 22 is one, and the second branch pipe 22 is connected to the head of the auxiliary pipe body 21. There is a distance H2 between the connection position of the auxiliary pipe body 21 and the second branch pipe 22 and the connector 3 provided at the outlet end of the second branch pipe 22; wherein, H1≥40mm, and / or, H2≥40mm. By setting the distance H1 and the distance H2, it is convenient for pipeline assembly and realizes the connection with the internal components of the automotive air conditioner.

[0048] In an exemplary embodiment of the present application, the outlet end of the first branch pipe 12, the outlet end of the second branch pipe 22 are connected to the subcooled regenerative heat exchanger, the head outlet end of the main pipe body 11 is connected to the three-box of the air conditioner, the tail outlet end of the main pipe body 11 is connected to the intermediate heat exchanger, the head outlet end of the auxiliary pipe body 21 is connected, and the tail outlet end of the auxiliary pipe body 21 is connected.

[0049] Further, the connecting member includes a pressing plate 4 and a double pipe clamp 5. By using the pressing plate 4 to fix the pipeline, it is possible to prevent the pipeline from shifting or vibrating due to external forces. While maintaining the stability of the pipeline, it avoids the pipeline from loosening or being damaged, and reduces the noise and vibration of the pipeline system. The double pipe clamp 5 can be made of metal or plastic. The double pipe clamp 5 is used to connect the main pipe body 11 and the auxiliary pipe body 21, and it is fixed on the pipeline by pressure or a spring. The double pipe clamp 5 is convenient to use and can make the pipeline layout more flexible.

[0050] It should be noted that the connecting member may further include structures such as pipe clamps, and the pipe clamps can be fixed to the pipeline through structures such as bolts and screws.

[0051] Specifically, the head of the main pipe body 11 and the head of the auxiliary pipe body 21 are connected by the pressing plate 4. Such a setting can ensure good fixation of the head of the main pipe body 11 and the head of the auxiliary pipe body 21, and avoid subsequent shaking and loosening.

[0052] Specifically, the middle part of the main pipe body 11 and the middle part of the auxiliary pipe body 21 are connected by at least one double pipe clamp 5. According to the lengths of the main pipe body 11 and the auxiliary pipe body 21, the number of double pipe clamps 5 used can be increased to make the connection more stable.

[0053] Specifically, the double pipe clamp 5 is a metal double pipe clamp. The metal double pipe clamp has better durability and compressive capacity, which is beneficial for long-term use. At the same time, the clamping force of the metal double pipe clamp is stronger, the clamping is more stable and reliable, and the pipeline is not easy to loosen.

[0054] In this embodiment, rubber pipe sections are provided at the positions of the main pipe body 11 and the auxiliary pipe body 21 close to the head. The pipe sleeves of the rubber pipe sections need to be clamped. If a sheet metal bracket is used to fix the main pipe body 11 and the auxiliary pipe body 21, when the pipe sleeve is clamped and fixed first and then the sheet metal bracket is welded, the pipe sleeve will be melted. If the sheet metal bracket is welded first and then the pipe sleeve is clamped, there will be insufficient clamping space. In this embodiment, a metal double pipe clamp is used to clamp the two pipes for fixation. The double pipe clamp does not need to be welded, solving the problems of the pipe sleeve being melted caused by clamping first and then welding, and insufficient space caused by welding first and then clamping.

[0055] Preferably, a damping rubber ring is provided inside the double pipe clamp 5. The setting of the damping rubber ring can reduce the vibration noise of the pipeline, thereby reducing the noise of the automotive air conditioner and improving the user experience.

[0056] In an exemplary embodiment of the present application, pressing plates 4 are respectively provided at the tail outlet ends of the main pipe body 11 and the auxiliary pipe body 21, further improving the stability of pipeline assembly.

[0057] Furthermore, at least part of the middle of the main pipe body 11 is a rubber hose section, and at least part of the middle of the auxiliary pipe body 21 is a rubber hose section. The length of the rubber hose section should reach a certain level to achieve the purposes of vibration reduction and easy installation.

[0058] Furthermore, the pipe radius of the main pipe body 11 is R1. The main pipe body 11 has a first bending section located between the head and the middle of the main pipe body 11, and the bending radius of the first bending section is R11. The pipe radius of the auxiliary pipe body 21 is R2. The auxiliary pipe body 21 has a second bending section located between the head and the middle of the auxiliary pipe body 21, and the bending radius of the second bending section is R21.

[0059] Preferably, 8mm ≤ R1 ≤ 12mm, 25mm ≤ R11 ≤ 50mm, 4.5mm ≤ R2 ≤ 6mm, 15mm ≤ R21 ≤ 20mm.

[0060] In an exemplary embodiment of the present application, R1 is 8mm, R11 is 25mm, R2 is 4.5mm, and R21 is 15mm.

[0061] Furthermore, at least one of the main pipe 1 and the auxiliary pipe 2 is provided with at least one bracket 7. By providing the bracket 7, the pipeline layout can be made more convenient.

[0062] In an exemplary embodiment of the present application, both the main pipe 1 and the auxiliary pipe 2 are aluminum pipes. Connecting heads 3 are welded to the head outlet ends of the main pipe 1 and the auxiliary pipe 2. Brazing is used between the main pipe 1 and the auxiliary pipe 2 and the connecting head 3, and laser welding is used between them and the bracket 7. The automotive air-conditioning pipeline in this embodiment has more than four connecting heads 3 and can connect three or more components.

[0063] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: The automotive air-conditioning pipeline in this embodiment can connect multiple air-conditioning components through one pipeline, can meet the independent operation or combined operation of multiple heat exchangers, effectively shortens the pipeline length, saves the layout space and reduces the installation difficulty. It solves the problems of large installation difficulty, high cost, high weight, and long installation working hours caused by a large number of pipes and long pipelines.

[0064] According to another specific embodiment of the present application, a vehicle is further provided, and the vehicle has the automotive air-conditioning pipeline in the above embodiment.

[0065] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. can be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures for the device. For example, if the device in the attached figure is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used here are made.
