Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a pipe fitting, a piping system, and a vehicle. Background Technology

[0002] With the rapid development of new energy vehicles, the application of power batteries is also increasing. Due to space and weight constraints, the installation space for power batteries in vehicles is relatively compact and narrow, making heat dissipation difficult. For power batteries, parameters such as performance and lifespan are significantly affected by temperature; therefore, battery cooling is an essential function for new energy vehicles. A common cooling method involves adding liquid cooling plates around the battery pack. Coolant is continuously pumped into the pipes of the liquid cooling plates, exchanging heat with the battery to cool the pack and maintain optimal battery performance under various operating conditions. In existing battery pack cooling systems, to maximize cooling efficiency, a double-layered liquid cooling plate configuration is used, requiring parallel cooling pipes to connect the two layers. Existing cooling pipes, to achieve this, employ main pipes, connectors, branch pipes, and joints; however, this structure results in a large space requirement for the cooling pipes. Furthermore, due to the different flow resistance of the upper and lower liquid cooling plates, the existing cooling pipe structure can also lead to inconsistent flow rates between the upper and lower liquid cooling plates, resulting in uneven temperature and affecting the battery pack life.

[0004] This application provides a pipe fitting, including a housing and a liquid flow channel. The housing includes an inlet section and a outlet section connected to each other. The liquid flow channel is disposed inside the housing and communicates the interior of the inlet section and the interior of the outlet section. The outlet section includes a first outlet and a second outlet, and the liquid flow channel includes a first outlet flow channel disposed near the first outlet and a second outlet flow channel disposed near the second outlet. The inner diameter of the first outlet flow channel is larger than the inner diameter of the second outlet flow channel.

[0005] Optionally, the first outlet channel and the second outlet channel are interconnected, and the first outlet channel and the second outlet channel extend in the same direction. The end of the inlet section is connected between the first outlet channel and the second outlet channel.

[0006] Optionally, the ratio of the inner diameter of the first outlet channel to the inner diameter of the second outlet channel is greater than 1 and less than or equal to 1.8.

[0007] Optionally, the outer diameter of the end of the discharge section near the first outlet is smaller than the outer diameter of the end of the discharge section near the second outlet.

[0008] Optionally, the housing further includes a connecting portion. The connecting portion is disposed at one end of the discharge section near the first outlet and is used to connect to a pipeline to be connected.

[0009] Optionally, the housing is integrally formed.

[0010] This application also provides a piping system including an inlet pipe, a first liquid-cooled plate, a second liquid-cooled plate, and a pipe fitting as described above. In the direction of gravity, the first liquid-cooled plate is disposed above the second liquid-cooled plate. The end of the inlet section furthest from the outlet section is connected to the inlet pipe.

Furthermore, in actual use, because the inner diameter of the first outlet flow channel of the pipe joint is larger than the inner diameter of the second outlet flow channel, the flow resistance difference between the first and second liquid cooling plates is balanced, thus balancing the coolant flow rates of the first and second liquid cooling plates, ensuring the flow channel uniformity of the first and second liquid cooling plates and the consistency of cooling effect. Therefore, this application, through the simple and compact design of the pipe joint, not only improves the space utilization of the vehicle but also ensures the temperature uniformity of the battery pack during operation, effectively extending the service life of the battery pack.

Detailed Implementation

[0023] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0025] This application provides a vehicle including a battery pack and a piping system 1. The piping system 1 includes a first liquid cooling plate 11 and a second liquid cooling plate 12, and the first liquid cooling plate 11 and the second liquid cooling plate 12 are respectively connected to opposite sides of the battery pack.

[0026] During vehicle operation, the piping system 1 enables the coolant to circulate between the first liquid cooling plate 11 and the second liquid cooling plate 12, thereby cooling the battery pack and ensuring the stability and safety of the battery pack as a power source during operation, as well as effectively extending the battery pack's service life. Furthermore, the arrangement of the first liquid cooling plate 11 and the second liquid cooling plate 12 ensures a more balanced cooling process for the battery pack, preventing poor temperature uniformity that could affect battery life.

[0027] In such Figure 1 The illustrated embodiment describes a piping system 1 provided in this application, which includes an inlet pipe, a pipe joint 14, and the first liquid cooling plate 11 and the second liquid cooling plate 12 described above. In the direction of gravity, i.e. Figure 1 In the Z direction shown, the first liquid cooling plate 11 is disposed above the second liquid cooling plate 12. One end of the pipe joint 14 is connected to the inlet pipe, and the other end is connected to the first liquid cooling plate 11 and the second liquid cooling plate 12 respectively.

[0028] As can be seen, the pipeline system 1, through the setting of the pipe joint 14, connects the inlet pipe in parallel with the first liquid cooling plate 11 and the second liquid cooling plate 12, thereby ensuring the cooling efficiency of the battery pack within the limited installation space of the vehicle, and effectively improving the fit, compactness, integration and space utilization of the vehicle's internal structure.

[0029] like Figure 2 As shown, the pipe fitting 14 of this application includes a housing 141, which includes an inlet section 1411 and an outlet section 1412 connected to each other. The outlet section 1412 includes a first outlet 1412a and a second outlet 1412b. The end of the inlet section 1411 furthest from the outlet section 1412 is connected to an inlet pipe. The first outlet 1412a is connected to a first liquid cooling plate 11, and the second outlet 1412b is connected to a second liquid cooling plate 12.

[0030] The installation of pipe joint 14 in the piping system 1 further improves the compactness of the overall structure of the piping system 1, thereby reducing the proportion of the piping system 1 in the vehicle's interior installation space, which in turn reduces the vehicle's weight, lowers its production cost to a certain extent, and improves its space utilization.

[0031] exist Figure 3 and Figure 4The illustrated embodiment describes a pipe fitting 14 provided in this application, comprising a liquid flow channel 142. The liquid flow channel 142 is disposed inside the housing 141 and connects the interior of the inlet section 1411 and the interior of the outlet section 1412. The liquid flow channel 142 includes a first outlet flow channel 1421 disposed near the first outlet 1412a and a second outlet flow channel 1422 disposed near the second outlet 1412b. The inner diameter of the first outlet flow channel 1421 is larger than the inner diameter of the second outlet flow channel 1422.

[0032] As can be seen, the design of the pipe joint 14 simplifies the combination structure of connectors and fittings used in the existing pipeline system 1 into an integrated pipe joint 14. In other words, the pipe joint 14 disclosed in this application replaces the combination structure of connectors and fittings. This design effectively improves the convenience of installing the pipeline system 1, and also reduces the installation space occupied by the pipeline system 1 in the vehicle, as well as the overall weight and production cost of the vehicle.

[0033] Furthermore, in actual use, because the first liquid cooling plate 11 is higher than the second liquid cooling plate 12 in the direction of gravity, and the piping system 1 needs to connect the two liquid cooling plates in parallel through pipes to ensure space utilization, this results in different flow resistances between the upper first liquid cooling plate 11 and the lower second liquid cooling plate 12. This leads to inconsistent cooling effects between the first liquid cooling plate 11 and the second liquid cooling plate 12, resulting in uneven temperature distribution in the battery pack and affecting its service life. (Refer to...) Figure 4 In this application, the inner diameter of the first outlet flow channel 1421 of the pipe joint 14 is larger than the inner diameter of the second outlet flow channel 1422. Based on the specific flow resistance of the first liquid cooling plate 11 and the second liquid cooling plate 12, the ratio of the inner diameters of the first outlet flow channel 1421 and the second outlet flow channel 1422 is set accordingly, thereby balancing the coolant flow rates of the first liquid cooling plate 11 and the second liquid cooling plate 12, ensuring the flow channel uniformity of the first liquid cooling plate 11 and the second liquid cooling plate 12, and the consistency of the cooling effect. Therefore, this application, through the simple and compact design of the pipe joint 14, not only improves the space utilization of the vehicle but also ensures the temperature uniformity of the battery pack during operation, effectively extending the service life of the battery pack.

[0034] In an optional embodiment, the first outlet channel 1421 and the second outlet channel 1422 are interconnected and extend in the same direction. The end of the inlet section 1411 is connected between the first outlet channel 1421 and the second outlet channel 1422.

[0035] refer to Figure 3 and Figure 4As can be seen, the overall structure of the pipe joint 14 is similar to a T-shape. This structural design merges the channels connecting the first liquid cooling plate 11 and the second liquid cooling plate 12 into one, and simultaneously supplies liquid to the two outlet channels through the liquid flow channel 142 of the inlet section 1411, thereby further improving the integration and integrity of the pipeline system and reducing the overall proportion of the pipe joint 14. In addition, since the first outlet flow channel 1421 and the second outlet flow channel 1422 extend in the same direction, the first outlet 1412a and the second outlet 1412b are respectively oriented towards the upper and lower ends in the Z direction, which further improves the convenience of connecting the pipe joint 14 to the first liquid cooling plate 11 and the second liquid cooling plate 12, and also avoids unnecessary pipe bends and coils in the pipeline system 1 due to mismatched opening directions. This also simplifies the structure of the pipeline system 1, reduces the space ratio, and improves the space utilization rate.

[0036] In an optional embodiment, the ratio of the inner diameter of the first outlet flow channel 1421 to the inner diameter of the second outlet flow channel 1422 is greater than 1 and less than or equal to 1.8. Specifically, the ratio of the inner diameter of the first outlet flow channel 1421 to the inner diameter of the second outlet flow channel 1422 can be 1.1:1, 1.2:1, 1.3:1, 1.4:1, 1.5:1, 1.6:1, 1.7:1, or 1.8:1.

[0037] It should be noted that in some optional embodiments, the specific specifications of the pipe joint 14 can be set according to different configurations of the piping system 1. For example, when the flow resistance difference between the upper and lower liquid cooling plates is small, the inner diameter ratio of the pipe joint 14 can be set accordingly to be smaller, such as 1.1:1 or 1.2:1. When the flow resistance difference between the upper and lower liquid cooling plates is large, the inner diameter ratio of the pipe joint 14 can be set accordingly to be larger, such as 1.8:1 or 1.7:1. Therefore, the limitation on the inner diameter ratio of the first outlet flow channel 1421 and the second outlet flow channel 1422 in this application allows the pipe joint 14 to adapt to various working conditions and various layout structures, and can effectively solve the problem of inconsistent flow rates between the upper and lower liquid cooling plates, thereby effectively ensuring the practicality of the pipe joint 14 and making its application range wider.

[0038] And in Figures 1 to 4In the described embodiments, the pipe joints 14 of the piping system 1 are all located between the first liquid cooling plate 11 and the second liquid cooling plate 12. The first liquid cooling plate 11 and the second liquid cooling plate 12 are connected in parallel through the first outlet 1412a and the second outlet 1412b. The ratio of the inner diameter of the first outlet flow channel 1421 to the inner diameter of the second outlet flow channel 1422 is set to 1.4:1, thereby ensuring that the fluid flow rate into the first liquid cooling plate 11 and the second liquid cooling plate 12 in the piping system 1 is equivalent. This prevents the battery pack from having poor temperature uniformity due to insufficient cooling, thereby effectively extending the service life of the battery pack and ensuring the stability and safety of the vehicle during operation.

[0039] In an optional embodiment, the outer diameter of the end of the discharge section 1412 near the first outlet 1412a is smaller than the outer diameter of the end of the discharge section 1412 near the second outlet 1412b.

[0040] Since the pipe joint 14 is located between the first liquid cooling plate 11 and the second liquid cooling plate 12, therefore, refer to Figure 2 It is understood that an additional flexible external pipe is needed in piping system 1 to connect the first outlet 1412a to the first liquid cooling plate 11. The aforementioned structural design of the discharge section 1412 allows the external pipe to be more easily fitted onto the end of the discharge section 1412 near the first outlet 1412a, thus ensuring a smooth connection between the pipe joint 14 and the first liquid cooling plate 11. Simultaneously, since the external pipe wraps around the end of the discharge section 1412 near the first outlet 1412a, the outer diameter of this end of the pipe joint 14 is smaller, minimizing the overall volume of the pipe joint 14 while ensuring overall structural strength, thereby improving the space utilization rate of piping system 1. Correspondingly, since the end of the discharge section 1412 near the second outlet 1412b does not require an external pipeline, and considering the smaller inner diameter of the second outlet flow channel 1422 described above, the larger outer diameter at this end will result in a thicker shell 141 at this end of the pipe joint 14. This further ensures the structural strength of the pipe joint 14 within the limited installation space, thus ensuring the stability and safety of the pipeline system 1 during vehicle operation.

[0041] Of course, it should be noted that the specific structure of the discharge section 1412 can be configured according to the actual installation location, user requirements, etc. For example, if an external pipeline is required at the second outlet 1412b, the outer diameter of the end of the discharge section 1412 closest to the second outlet 1412b can be set to be smaller accordingly; if external pipelines are required at both ends of the discharge section 1412, the outer diameters of both ends of the discharge section 1412 can be reduced accordingly. Therefore, this application does not impose any restrictions on this.

[0042] In an optional embodiment, the housing 141 further includes a connecting portion 1413. The connecting portion 1413 is disposed at one end of the discharge section 1412 near the first outlet 1412a and is used to connect to the pipeline to be connected.

[0043] As described above, an external pipeline is required at the end of the discharge section 1412 near the first outlet 1412a, so its outer diameter is smaller to facilitate easier and faster pipeline connection. Furthermore, providing a connecting part 1413 at the end of the pipe joint 14 near the first outlet 1412a further improves the convenience of connecting the pipe joint 14 to the external pipeline, as well as the stability and safety of the connection.

[0044] It should be noted that, in optional embodiments, the specific structure of the connecting part 1413 should be set according to the actual structure of the pipeline to be connected. For example, if the pipeline to be connected uses a threaded connection, the connecting part 1413 is set to a threaded shape; if the pipeline to be connected uses a snap-fit ​​connection, the connecting part 1413 is set to a slot, etc. Therefore, this application does not impose any limitations on this. In the embodiments described in this application, the connecting part 1413 is set to be adapted to a CQC quick-connect fitting (China Quality Certification Centre, i.e., a quick-connect fitting certified by the China Quality Certification Centre), so that the connecting part 1413 and the pipeline to be connected can be connected via a CQC quick-connect fitting. This setting simplifies the installation process of the pipeline system 1 and effectively solves the problem of difficult assembly for workers.

[0045] Furthermore, in other alternative embodiments, the location of the connecting part 1413 can also be set according to the actual structure of the pipeline system 1. For example, the connecting part 1413 can be set at one end of the discharge section 1412 near the second outlet 1412b so that the discharge section 1412 can be connected to the second liquid cooling plate 12; or the connecting part 1413 can be set at both ends of the discharge section 1412 so that it can be connected to the first liquid cooling plate 11 and the second liquid cooling plate 12 respectively, etc. Therefore, this application does not limit this.

[0046] In an optional embodiment, the piping system 1 further includes a cooling pipe 13. One end of the cooling pipe 13 is connected to the first outlet 1412a via a connector 1413, and the other end is connected to the first liquid cooling plate 11.

[0047] As described above, since the pipe joint 14 of this application is located between the first liquid cooling plate 11 and the second liquid cooling plate 12, an external cooling pipe 13 needs to be connected at the first outlet 1412a to connect the first outlet 1412a to the first liquid cooling plate 11; while the end of the discharge section 1412 near the second outlet 1412b can be directly welded to the second liquid cooling plate 12. This arrangement eliminates traditional bolt fastening or sealant bonding methods, effectively simplifying the assembly process, improving assembly convenience, saving assembly time and production costs. At the same time, through CQC quick-connect connection and welding, the overall reliability and safety of the piping system 1 are effectively improved, reducing the probability of failure during vehicle operation, thereby ensuring the user's driving experience.

[0048] Of course, similar to the above, depending on the specific structure of the vehicle and pipeline system 1, the structure of the pipe joint 14 can be set accordingly. For example, both ends of the discharge section 1412 can be connected by welding, or both can be connected by CQC quick-connect, etc. Therefore, this application does not limit this.

[0049] In an optional embodiment, the housing 141 is integrally formed.

[0050] The aforementioned structural design makes the overall structure of the pipe joint 14 more integrated and compact, effectively improving the space utilization of the pipeline system 1 and enhancing the convenience of the pipe joint 14 during production and assembly. Simultaneously, the one-piece molded pipe joint 14 ensures its reliability and safety during operation, guaranteeing the stability and service life of the vehicle during operation.

[0051] It is worth mentioning that, in practical applications, because the pipe joint 14 is integrally molded, it can replace the "connector plus joint" structure in the original pipeline system 1. This effectively reduces the overall proportion of the pipeline system 1 in the vehicle installation space, reduces vehicle production costs, and improves assembly efficiency and ease of assembly. If the pipe joint 14 is too long during installation, the inlet section 1411 can be cut off directly, and then connected at the cut end with a hose or other external pipeline, further reducing the overall volume of the pipe joint 14. This method also further expands the applicability of the pipe joint 14.

[0052] In optional embodiments, such as Figure 2 As shown, the battery pack includes a side panel 2 of the housing, and the inlet section 1411 of the pipe joint 14 passes through the side panel 2 of the housing and is sealed between the pipe joint 14 and the side panel 2 of the housing.

[0053] During vehicle assembly, the pipe connector 14 can be pre-installed to mate with the battery pack, with its inlet section 1411 passing through and protruding from the side panel 2 of the battery pack housing to facilitate subsequent connection of other external pipelines. Compared to traditional systems with main pipelines, connectors, branch pipelines, and joints, the installation of the pipe connector 14 effectively reduces the failure rate of the pipeline system 1 and greatly improves the convenience of installation, disassembly, and maintenance. Furthermore, the inlet section 1411 and the side panel 2 of the housing can be sealed together using welding, bonding, or other methods, further ensuring the airtightness of the battery pack and guaranteeing the stability and safety of the vehicle during operation.

[0054] Overall, during vehicle use, the piping system 1 delivers coolant through pipes to the end of the inlet section 1411 of the pipe connector 14, flows into the outlet section through the liquid flow channel 142, and is split into the first outlet flow channel 1421 and the second outlet flow channel 1422. Since the first liquid cooling plate 11 is located on the upper layer of the battery pack and the second liquid cooling plate 12 is located on the lower layer of the battery pack, and the first outlet flow channel 1421 is connected to the first liquid cooling plate 11 and the second outlet flow channel 1422 is connected to the second liquid cooling plate 12, the coolant needs to overcome gravity to flow into the first liquid cooling plate 11, while the fluid flowing into the second liquid cooling plate 12 is subject to gravity and flows faster and at a greater flow rate. This results in different flow resistances for the first liquid cooling plate 11 and the second liquid cooling plate 12. The pipe connector 14 provided in this application, by setting the inner diameter ratio of the first outlet flow channel 1421 and the second outlet flow channel 1422 to 1.4:1, allows more coolant to flow into the first outlet flow channel 1421, thereby overcoming the flow resistance difference between the first liquid cooling plate 11 and the second liquid cooling plate 12, ensuring the balance of the upper and lower liquid cooling plate flow channels, and thus making the cooling effect and temperature uniform on both sides of the battery pack consistent. This ensures the stability and reliability of the vehicle during operation and effectively improves the service life of the battery pack and the vehicle. At the same time, the pipe connector 14 has good integration effect, and its structure is simple and compact, effectively reducing the proportion of the pipeline system 1 occupied in the vehicle's installation space, saving internal space of the battery pack, not encroaching on the placement space of other electronic components, reducing the overall vehicle weight, and lowering production costs.

[0055] Of course, depending on the actual application scenario, other connectors can also be used as pipe connector 14, such as a tee connector with two pipe sections connected to the upper and lower liquid cooling plates respectively. This method can separate the first outlet flow channel 1421 and the second outlet flow channel 1422, facilitating disassembly or maintenance of both. Therefore, it should be noted that the overall structure and arrangement of the pipe connector 14 are not limited in the embodiments of this application. In other embodiments, solutions that reduce volume and balance flow through integrated connectors should be included within the scope of protection of this application.

[0056] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
