Abstract
Description
Technical Field
[0001] This application relates to the field of fluid distribution technology, and in particular to a connector structure, a fluid flow system, and a vehicle. Background Technology
[0002] Four-way connectors are commonly used accessories in fluid flow systems to divert fluid from the main circulation loop to other branch loops. However, these four-way connectors do not have flow distribution capabilities. The flow rate in the branch loop is the same as that in the main circulation loop, but the flow rate requirements of the main circulation loop and the branch loop are different. This causes the fluid in the main circulation loop to impact the branch loop when it flows to the branch loop, resulting in noise and other problems. Utility Model Content
[0003] This application provides a connector structure, a fluid flow system, and a vehicle to solve the problem that four-way connectors in fluid flow systems in the prior art lack flow distribution functionality.
[0004] In a first aspect, this application provides a connector structure, including a main pipe, a first branch pipe, a second branch pipe, and a flow-limiting structure. The main pipe includes a first sub-pipe and a second sub-pipe, which are inclined and in fluid communication. The first sub-pipe has an outlet port, and the second sub-pipe has an inlet port. One end of the first branch pipe is in fluid communication with the first sub-pipe through the outlet port. One end of the second branch pipe is in fluid communication with the second sub-pipe through the inlet port, and the other end of the second branch pipe is in fluid communication with the other end of the first branch pipe. The flow-limiting structure is disposed within the main pipe, along the flow direction of the fluid within the main pipe, and is located between the outlet port and the inlet port. The flow-limiting structure is configured to limit the flow rate of the fluid flowing from the first sub-pipe to the second sub-pipe.
[0005] In one possible implementation, the flow-limiting structure is disposed on the inner wall of a first side of the main pipe along the radial direction of the main pipe, the flow-limiting structure is spaced apart from the inner wall of a second side of the main pipe, and a flow-limiting orifice is formed between the flow-limiting structure and the inner wall of the second side of the main pipe, the flow-limiting orifice being configured to limit the flow rate of fluid flowing from the first sub-pipe to the second sub-pipe.
[0006] In one possible implementation, the flow-limiting structure is disposed around the inner wall of the main pipe, and the flow-limiting structure is configured to prevent fluid in the first sub-pipe from flowing directly into the second sub-pipe;
[0007] The flow-limiting structure is provided with at least one flow-limiting port, and the first sub-pipe and the second sub-pipe are in fluid communication through the flow-limiting port. The flow-limiting port is configured to limit the flow rate of fluid flowing from the first sub-pipe to the second sub-pipe.
[0008] In one possible implementation, the flow-limiting structure is located inside the first sub-pipe; or, the flow-limiting structure is located inside the second sub-pipe; or, the flow-limiting structure is partially located inside the first sub-pipe and partially located inside the second sub-pipe.
[0009] In one possible implementation, the first sub-pipe has a defined first axis, the second sub-pipe has a defined second axis, the first axis and the second axis are inclined and form an angle between the first axis and the second axis, the angle being greater than 0° and less than 180°.
[0010] In one possible implementation, the first sub-pipe has a first end and a second end disposed opposite to each other, and the second sub-pipe has a third end and a fourth end disposed opposite to each other, the third end being connected to the second end and in fluid communication with the second end.
[0011] In one possible implementation, the first end is provided with a main inlet, and the outlet branch is located between the first end and the second end; and / or
[0012] The fourth end is provided with a main outlet, and the inlet branch is located between the third end and the fourth end.
[0013] In one possible implementation, the connector structure further includes a connection assembly connected to at least one of the main pipe, the first branch pipe, and the second branch pipe, the connection assembly being configured to connect to the vehicle body.
[0014] Secondly, this application also provides a fluid flow system, including a first pipeline, a second pipeline, and the aforementioned connector structure, wherein the two ends of the first pipeline are fluidly connected to the main inlet and the main outlet of the main pipeline, respectively, and the two ends of the second pipeline are fluidly connected to the first branch pipe and the second branch pipe, respectively.
[0015] Thirdly, this application also provides a vehicle, including a body and the aforementioned fluid flow system, the fluid flow system being connected to the body.
[0016] In the connector structure of this application, a flow-limiting structure is provided inside the main pipeline. This structure restricts the flow rate of fluid from the first sub-pipe to the second sub-pipe, thereby adjusting the flow rate of fluid from the main pipeline to the first branch pipe. This achieves flow distribution between the main pipeline loop and the loop formed by the first and second branch pipes, preventing the fluid from impacting the first branch pipe and causing noise or vibration. Furthermore, the main pipeline consists of the first and second sub-pipes arranged at inclinations to each other. This inclination allows the inflow and outflow directions of the fluid within the main pipeline to be different, accommodating the need for the connector structure at corner locations and expanding its applicability.

[0029] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0030] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a connector structure 100, including a main pipe 10, a first branch pipe 21, a second branch pipe 22, and a flow-limiting structure 40.
[0031] The main pipe 10 includes a first sub-pipe 11 and a second sub-pipe 12. The first sub-pipe 11 and the second sub-pipe 12 are inclined and are in fluid communication with each other, so that fluid can flow between the first sub-pipe 11 and the second sub-pipe 12.
[0032] The first sub-pipe 11 is provided with an outlet branch 114, and the second sub-pipe 12 is provided with an inlet branch 124. One end of the first branch pipe 21 is fluidly connected to the first sub-pipe 11 through the outlet branch 114, allowing fluid in the first sub-pipe 11 to flow into the first branch pipe 21. One end of the second branch pipe 22 is fluidly connected to the second sub-pipe 12 through the inlet branch 124, and the other end of the second branch pipe 22 is fluidly connected to the other end of the first branch pipe 21, allowing fluid flowing into the first branch pipe 21 to flow into the second branch pipe 22 and then back into the main pipe 10 through the inlet branch 124.
[0033] A flow-limiting structure 40 is installed within the main pipe 10, positioned between the outflow branch 114 and the inflow branch 124 along the flow direction of the fluid within the main pipe 10. The flow rate of the fluid flowing from the first sub-pipe 11 to the second sub-pipe 12 is adjusted by the flow-limiting structure 40. Furthermore, by adjusting the shape or size of the flow-limiting structure 40 within different joint structures 100, different flow rate limits can be achieved for the fluid flowing from the first sub-pipe 11 to the second sub-pipe 12 within different joint structures 100.
[0034] Thus, in the connector structure 100 of this application, a flow-limiting structure 40 is provided inside the main pipe 10. By limiting the flow rate of fluid from the first sub-pipe 11 to the second sub-pipe 12, the flow rate of fluid from the main pipe 10 to the first branch pipe 21 is adjusted. This achieves flow distribution between the loop containing the main pipe 10 and the loop consisting of the first and second branch pipes 21 and 22, preventing the fluid from impacting the first branch pipe 21 and causing noise or vibration after flowing from the main pipe 10 to the first branch pipe 21. In addition, the main pipe 10 is composed of the first sub-pipe 11 and the second sub-pipe 12 arranged at inclinations to each other. This inclination structure allows the inflow and outflow directions of the fluid in the main pipe 10 to be different, which can adapt to the arrangement requirements of the connector structure 100 at corner positions and improve the applicability of the connector structure 100.
[0035] Please combine Figures 1 to 2In one embodiment, the first sub-pipe 11 has a defined first axis H1, and extends along the direction of the first axis H1. The second sub-pipe 12 has a defined second axis H2, and extends along the direction of the second axis H2. The first axis H1 and the second axis H2 are inclined and form an angle A between them. The angle A is greater than 0° and less than 180°. Thus, the inclination of the first sub-pipe 11 and the second sub-pipe 12 can be adjusted by adjusting the size of the angle A, thereby allowing the selection of a suitable main pipe 10 according to the specific installation position requirements, such as the boundary position or corner position of the main pipe 10.
[0036] In this embodiment, the first sub-pipe 11 is generally a cylindrical structure with open ends and a hollow interior. Along the direction of the first axis H1, the first sub-pipe 11 has a first end 111 and a second end 112 disposed opposite to each other. The second sub-pipe 12 is also generally a cylindrical structure with open ends and a hollow interior. Along the direction of the second axis H2, the second sub-pipe 12 has a third end 121 and a fourth end 122 disposed opposite to each other. The third end 121 of the second sub-pipe 12 is connected to the second end 112 of the first sub-pipe 11, and the third end 121 of the second sub-pipe 12 is integrally formed into the second end 112 of the first sub-pipe 11 to improve the production efficiency of the main pipe 10. It is understood that in other embodiments, the third end 121 of the second sub-pipe 12 and the second end 112 of the first sub-pipe 11 can also be connected by welding or other methods.
[0037] In this embodiment, the first sub-pipe 11 has a first inner cavity 113 and a main inlet 110 at its first end 111. The second sub-pipe 12 has a second inner cavity 123 and a main outlet 120 at its fourth end 122. The third end 121 of the second sub-pipe 12 is in fluid communication with the second end 112 of the first sub-pipe 11.
[0038] Along the direction of the first axis H1, the main inlet 110 extends from the end face of the first end 111 away from the second end 112 toward the side where the second end 112 is located, to connect with the first inner cavity 113. Along the direction of the second axis H2, the main outlet 120 extends from the end face of the fourth end 122 away from the third end 121 toward the side where the third end 121 is located, to connect with the second inner cavity 123. The end of the first inner cavity 113 away from the first end 111 connects with the end of the second inner cavity 123 away from the fourth end 122.
[0039] Thus, the fluid flows into the first sub-pipe 11 through the self-flowing inlet 110, then into the second sub-pipe 12, and finally out of the second sub-pipe 12 through the main outlet 120.
[0040] Please combine Figures 1 to 2In one embodiment, an outlet branch 114 is provided on the outer peripheral surface of the first sub-pipe 11. The outlet branch 114 is connected to the first inner cavity 113 and is located between the first end 111 and the second end 112, so that part of the fluid flowing into the first inner cavity 113 from the autonomous inlet 110 flows into the first branch pipe 21 through the outlet branch 114, and the other part flows into the second sub-pipe 12. Since the flow rate of the fluid flowing into the first inner cavity 113 from the autonomous inlet 110 is fixed, when the flow rate of the fluid in the first sub-pipe 11 is changed by the flow limiting structure 40, the flow rate of the fluid flowing into the second sub-pipe 12 also changes accordingly, thereby realizing the flow distribution of fluid between the second sub-pipe 12 and the first branch pipe 21.
[0041] The outer circumferential surface of the second sub-pipe 12 is provided with an inlet branch 124. The inlet branch 124 is connected to the second inner cavity 123, and the inlet branch 124 is located between the third end 121 and the fourth end 122, so that the fluid that flows into the second inner cavity 123 after being adjusted by the flow-limiting structure 40 can merge with the fluid that flows into the second inner cavity 123 from the inlet branch 124 and then flow out of the second sub-pipe 12 from the main outlet 120.
[0042] In this embodiment, the first branch pipe 21 is a cylindrical structure with open ends and a hollow interior. The first branch pipe 21 is integrally formed on the outer circumferential surface of the first sub-pipe 11, and one end of the first branch pipe 21 connects to the outflow port 114. The second branch pipe 22 is a cylindrical structure with open ends and a hollow interior. The second branch pipe 22 is integrally formed on the outer circumferential surface of the second sub-pipe 12, and one end of the second branch pipe 22 connects to the inflow port 124. Both the first branch pipe 21 and the second branch pipe 22 are integrally formed on the main pipe 10, which improves the production efficiency of the joint structure 100.
[0043] It is understood that in other embodiments, the first branch pipe 21 and the second branch pipe 22 may also be connected to the main pipe 10 by means of welding or other methods.
[0044] In this embodiment, the extension direction of the first branch pipe 21 is perpendicular to the direction of the first axis H1, and the extension direction of the second branch pipe 22 is perpendicular to the direction of the second axis H2, and the extension directions of the first branch pipe 21 and the extension directions of the second branch pipe 22 are parallel to each other.
[0045] It is understood that, in other embodiments, the position of the first branch pipe 21 relative to the first sub-pipe 11 and the position of the second branch pipe 22 relative to the second sub-pipe 12 can be adaptively adjusted according to actual installation requirements.
[0046] Please combine Figures 1 to 3In one embodiment, a flow-limiting structure 40 is disposed on the inner wall of the first side 1 of the main pipe 10 along the radial direction of the main pipe 10. The flow-limiting structure 40 is spaced apart from the inner wall of the second side 2 of the main pipe 10, and a flow-limiting orifice 50 is formed between the flow-limiting structure 40 and the inner wall of the second side 2 of the main pipe 10.
[0047] In this embodiment, the flow-limiting structure 40 is integrally formed on the inner wall of the first side 1 of the main pipe 10, which facilitates the direct processing of the integrally formed main pipe 10 and flow-limiting structure 40 through a mold. Furthermore, the way in which the flow-limiting structure 40 is formed on the inner wall of the main pipe 10 facilitates demolding and improves production efficiency.
[0048] The flow-limiting structure 40 is a protruding structure integrally formed on the inner wall of the main pipe 10. The surface of the flow-limiting structure 40 on the side of the inner wall away from the first side 1 of the main pipe 10 is designated as the flow-limiting surface P. The space between the flow-limiting surface P and the inner wall of the second side 2 of the main pipe 10 is the flow-limiting port 50. The flow-limiting surface P is curved, and the flow-limiting surface P is smoothly connected to the inner surface of the main pipe 10 to avoid problems such as excessive noise when the fluid flows through the flow-limiting surface P.
[0049] Specifically, along the radial direction of the main pipe 10, the distance between the flow-limiting surface P and the inner wall of the second side 2 of the main pipe 10 can be adjusted by adjusting the thickness of the flow-limiting structure 40, thereby adjusting the diameter of the flow-limiting port 50.
[0050] In this embodiment, the flow limiting structure 40 is partially located inside the first sub-pipe 11 and partially located inside the second sub-pipe 12. That is, the flow limiting structure 40 is located at the corner between the first sub-pipe 11 and the second sub-pipe 12. Part of the flow limiting structure 40 is integrally formed on the inner wall of the first sub-pipe 11, and the other part of the flow limiting structure 40 is integrally formed on the inner wall of the second sub-pipe 12.
[0051] It is understood that, in other embodiments, the flow-limiting structure 40 may be located within the first sub-pipe 11, that is, the flow-limiting structure 40 is integrally formed on the inner wall of the first sub-pipe 11, and the flow-limiting structure 40 is located in the region between the outlet branch 114 and the second end 112 of the first sub-pipe 11. Alternatively, the flow-limiting structure 40 may be located within the second sub-pipe 12, that is, the flow-limiting structure 40 is integrally formed on the inner wall of the second sub-pipe 12, and the flow-limiting structure 40 is located in the region between the inlet branch 124 and the third end 121 of the second sub-pipe 12.
[0052] Please combine Figure 4 And see Figure 1In another embodiment, the flow-limiting structure 40 is disposed around the inner wall of the main pipe 10, and the flow-limiting structure 40 is configured to prevent fluid in the first sub-pipe 11 from flowing directly into the second sub-pipe 12. The flow-limiting structure 40 is generally cylindrical and is adapted to the main pipe 10. The flow-limiting structure 40 is integrally formed on the inner wall of the main pipe 10, so that the cavity inside the main pipe 10 is divided into two non-communicating sub-cavities by the flow-limiting structure 40.
[0053] The flow-limiting structure 40 is provided with at least one flow-limiting port 50, and the flow-limiting port 50 penetrates the flow-limiting structure 40, so that the first sub-pipe 11 and the second sub-pipe 12 are in fluid communication through the flow-limiting port 50, so that the fluid in the first sub-pipe 11 must pass through the flow-limiting effect of the flow-limiting port 50 before flowing into the second sub-pipe 12. The number of flow-limiting ports 50 can be one or two, and the specific number is not limited in this application.
[0054] In other embodiments, the flow-limiting structure 40 may also be connected to the main pipe 10 by welding.
[0055] In this embodiment, the flow-limiting structure 40 is located at the corner between the first sub-pipe 11 and the second sub-pipe 12, and the flow-limiting structure 40 closes the connection between the opening of the second end 112 of the first sub-pipe 11 and the opening of the third end 121 of the second sub-pipe 12, thereby isolating the first inner cavity 113 and the second inner cavity 123.
[0056] It is understood that in other embodiments, the flow limiting structure 40 may also be located within the first sub-pipe 11, or the flow limiting structure 40 may be located within the second sub-pipe 12.
[0057] It is understood that in other embodiments, the flow limiting structure 40 may also adopt a continuous sawtooth structure or a slope structure or other special shapes. The specific structure of the flow limiting structure 40 can be selected according to the actual design requirements. It is sufficient that the flow rate of the fluid flowing from the first sub-pipe 11 to the second sub-pipe 12 can be adjusted by setting the flow limiting structure 40.
[0058] Please combine Figure 3 And see Figure 6 In one embodiment, the connector structure 100 further includes a connection assembly 30. The connection assembly 30 is connected to at least one of the main pipe 10, the first branch pipe 21, and the second branch pipe 22. The connection assembly 30 is configured to be connected to the vehicle body 80.
[0059] The connecting assembly 30 includes a connecting base 31 and a connecting member 32. The connecting base 31 has a first connecting hole 311 and a second connecting hole 312. A first branch pipe 21 passes through the first connecting hole 311 and is connected to the connecting base 31 by welding or integral molding. A second branch pipe 22 passes through the second connecting hole 312 and is connected to the connecting base 31 by welding or integral molding.
[0060] The connector 32 is a bolt or pin, etc. One end of the connector 32 is fixed to the connector 31, and the other end can be fixed to the vehicle body 80, thereby achieving relative fixation between the connector 31 and the vehicle body 80, and consequently, relative fixation between the main pipe 10 and the vehicle body 80. The number of connectors 32 can be two or three, which can improve the stability of the connection between the connector 31 and the vehicle body 80. In other embodiments, the connector 32 can also be used as a pin or other positioning element to achieve positioning between the connector 31 and the vehicle body 80.
[0061] It is understood that in other embodiments, the connector 31 may also be connected to the main pipe 10, or the connector 31 may be connected separately to the first branch pipe 21 or the second branch pipe 22. The specific connection position of the connector 31 can be selected according to the actual installation requirements.
[0062] like Figures 5 to 6 As shown, and see also Figure 2 This embodiment also provides a fluid flow system 200, including a first pipe 70, a second pipe 60, and the aforementioned connector structure 100. The two ends of the first pipe 70 are fluidly connected to the main inlet 110 and the main outlet 120 of the main pipe 10, respectively, and the two ends of the second pipe 60 are fluidly connected to the first branch pipe 21 and the second branch pipe 22, respectively.
[0063] In this embodiment, the fluid flow system 200 can be a thermal management system applied to the vehicle 300, with both the first pipe 70 and the second pipe 60 serving as cooling pipes for the flow of cooling medium. The loop formed by the first pipe 70 and the main pipe 10 can serve as a motor cooling loop. In this case, the first pipe 70 is equipped with a motor 71, a radiator 72, a water pump 73, and other devices. Along the fluid flow direction of the first pipe 70, the motor 71, radiator 72, water pump 73, and main pipe 10 are sequentially fluidly connected to achieve heat dissipation for the motor 71. It is understood that in other embodiments, the first pipe 70 can also be applied to other structures of the vehicle 300 requiring heat dissipation, and the devices installed on the first pipe 70 can be adaptively adjusted according to actual design requirements.
[0064] A heating element 61 is installed on the second pipe 60. After connecting the second pipe 60 to the first branch pipe 21 and the second branch pipe 22, the cooling fluid in the first pipe 70 can be diverted to the heating element 61, thereby utilizing the fluid in the first pipe 70 to dissipate heat from the heating element 61. The fluid that has completed heat exchange with the heating element 61 can then flow back to the first pipe 70 to be cooled and reused. It is understood that the heating element 61 can be a device such as a controller that generates heat during operation. The controller has multiple built-in algorithm modules, which generate a large amount of heat during operation. Therefore, the cooling fluid in the first pipe 70 can be used to dissipate heat from the controller, ensuring its safety during use.
[0065] It is understood that in other embodiments, the fluid flow system 200 may also be other fluid systems that allow fluid flow. The fluid system adopts the above-described connector structure 100 to realize the flow distribution between one fluid pipe and another fluid pipe in the fluid system, and avoids noise or vibration caused by impact after the fluid flows from one fluid pipe to another fluid pipe.
[0066] like Figures 5 to 7 As shown, and see also Figure 2 This embodiment also provides a vehicle 300, including a body 80 and the aforementioned fluid flow system 200, the fluid flow system 200 being connected to the body 80.
[0067] A floor plate 90 is provided inside the vehicle body 80, and mounting holes 91 are provided on the floor plate 90. The connecting seat 31 is fixed in the mounting holes 91. The main pipe 10 is located below the floor plate 90, that is, outside the passenger space of the vehicle 300, while the first branch pipe 21 and the second branch pipe 22 are located above the floor plate 90, that is, inside the passenger space of the vehicle 300. This allows the fluid of the first pipe 70 below the floor plate 90 to be diverted to the heating component 61 in the interior space above the floor plate 90.
[0068] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
