Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to a connecting pipe for an intercooler, an engine system, and a vehicle. Background Technology

[0002] To meet performance requirements, current hybrid engines are equipped with intercoolers and EGR systems. Intercoolers are typically located upstream of the engine's intake manifold. Due to their structural function and the effect of the EGR system, condensation can occur in the intercooler. If this condensation accumulates to a certain amount, and the vehicle accelerates rapidly, the accumulated condensation can rush into the engine's combustion chamber with the gas, causing cylinder flooding and engine stalling. This can lead to abnormal vehicle vibration and insufficient power, reducing the overall driving experience. Utility Model Content

[0003] This application aims to at least partially address one of the technical problems in the related art.

[0004] To solve the above-mentioned technical problems, this application provides a connecting pipe with a homogenization structure inside. The homogenization structure can disperse and break up the liquid or homogenize its flow, so that the liquid can be fully mixed with the gas, avoiding the situation where the liquid easily enters the single combustion chamber of the engine under centrifugal force, causing cylinder flooding and flameout.

[0005] The technical solution adopted to achieve the purpose of this application is as follows: The connecting pipe of this application includes: A pipe body for the flow of a medium, the medium including liquids and gases; A homogenizing structure is disposed within the tube body and is used to disperse the liquid so as to fully mix the liquid and the gas.

[0006] In some technical solutions, the pipe body is provided with an inlet, and the homogenization structure and the inlet are arranged opposite to each other in the flow direction of the medium along the inlet.

[0007] In some technical solutions, the projection of the homogenizing structure is located within the outline of the projection of the inlet in the flow direction.

[0008] In some technical solutions, the pipe body is also provided with an outlet, which is located above the inlet.

[0009] In some technical solutions, the homogenization structure includes multiple homogenizing elements, all of which are fixed to the inner wall of the tube body and are arranged at intervals along the extension direction of the tube body.

[0010] In some technical solutions, multiple homogenizing elements are arranged at an angle downwards, and along the extending direction, the angle of inclination of the multiple homogenizing elements tends to decrease first and then increase.

[0011] In some technical solutions, the plurality of homogenizing elements include a first homogenizing element and a second homogenizing element, and the tube body has a vertically arranged central axial surface; One end of the first homogenizing member is located at or near the central axis surface, and the other end of the first homogenizing member extends to one side of the central axis surface. One end of the second homogenizing member is located at or near the central axis surface, and the other end of the second homogenizing member extends to the other side of the central axis surface.

[0012] In some technical solutions, the angle α formed by the extension direction of the first homogenizing member and the central axial surface is 25° to 45°. And / or, the angle b formed by the extension direction of the second homogenizing member and the central axial surface is 65° to 85°.

[0013] In some technical solutions, the vertical distance M between two adjacent homogenizing elements is 10mm to 20mm.

[0014] In some technical solutions, the homogenizing element includes a first extension and a second extension, which are arranged at an angle to make the homogenizing element herringbone-shaped.

[0015] In some technical solutions, the pipe body is arc-shaped, and both ends of the pipe body are provided with connecting flanges.

[0016] The engine system of this application includes an intercooler, a throttle, and a connecting pipe as described in any of the above embodiments, wherein the inlet end of the connecting pipe is connected to the intercooler, and the outlet end of the connecting pipe is connected to the throttle.

[0017] The vehicle of this application includes the engine system as described in any of the above embodiments.

[0018] As can be seen from the above technical solution, the connecting pipe, engine system and vehicle of this application are provided with a homogenization structure in the connecting pipe. The homogenization structure can disperse and break up the liquid or make it flow evenly, so that the liquid can be fully mixed with the gas. This avoids the liquid from easily entering the single combustion chamber of the engine under centrifugal force and causing cylinder flooding and stalling, thereby avoiding abnormal vibration of the whole vehicle and ensuring the running power of the whole vehicle.

[0026] It should be noted that this application is based on the inventor's discovery and understanding of the following facts and problems: In existing technology, water-to-intercooler is usually located below the intake manifold. With the support of the EGR system, condensate may be released in the intercooler. If the condensate accumulates to a certain amount in the outlet chamber of the intercooler, when the vehicle accelerates rapidly, the accumulated condensate will rush into the combustion chamber with the intake airflow, causing cylinder flooding and engine shutdown, resulting in abnormal vibration of the vehicle and insufficient power.

[0027] Based on the above facts and problems, this application provides a connecting pipe.

[0028] The following describes an embodiment of the connecting tube of this application.

[0029] It should be noted that the connecting pipe in this application is mainly used in vehicles, specifically for connecting the vehicle's intercooler and the engine's intake manifold and for transporting the medium. Furthermore, the various directions in the embodiments of this application can correspond to the actual directions of the connecting pipe during use. For example, the connecting pipe can be arranged vertically in the up-down direction, with the front side from bottom to top as the front, the rear side from bottom to top as the rear, the left side from bottom to top as the left, and the right side from bottom to top as the right.

[0030] like Figure 1 As shown, the connecting pipe of this application includes a pipe body 1 and a homogenization structure 2.

[0031] The pipe body 1 is for the flow of media, including liquids and gases. For example, the material of the pipe body 1 can be metal, plastic, etc. The pipe body 1 can be a casting. In other embodiments, the pipe body 1 can also be formed by injection molding, splicing and welding, etc.

[0032] In use, the tube body 1 can be used for the flow of medium. The medium can include liquid and gas depending on its form, that is, the medium can be a gas-liquid mixture. The tube body 1 meets the need for directional delivery of medium to the intake manifold.

[0033] The homogenization structure 2 is disposed inside the tube body 1, and the homogenization structure 2 is used to disperse the liquid to ensure thorough mixing of the liquid and gas. For example, as... Figure 1 As shown, the homogenization structure 2 can be fixed on the inner circumferential wall of the tube body 1. The homogenization structure 2 can be a series of protrusions, bumps, or other structures protruding from the inner circumferential wall of the tube body 1. In other embodiments, the homogenization structure 2 can also be a structure similar to a mesh plate, in which case the effect of homogenizing the liquid can also be achieved through the through holes on the homogenization structure 2.

[0034] When the medium is introduced into the pipe 1, the liquid, due to its inertia and centrifugal force, will flow along the inner circumferential wall of the pipe 1. The liquid flowing along the wall will collide with the homogenization structure 2, thereby breaking up the liquid through the blocking effect of the homogenization structure 2, which plays the role of homogenization and diversion of the liquid. The homogenized liquid will be fully mixed with the gas, thus avoiding the situation where the liquid flows into one or more engine combustion chambers, thereby avoiding problems such as cylinder flooding and flameout in these combustion chambers, so that all combustion chambers can operate stably, avoiding abnormal vehicle vibration and insufficient power.

[0035] In some embodiments, the pipe body 1 is provided with an inlet 11, and the homogenizing structure 2 and the inlet 11 are arranged opposite each other in the flow direction of the medium along the inlet 11. For example, as Figure 1 As shown, the inlet 11 of the pipe body 1 can be located at the rear side of the pipe body 1. The inlet 11 can be a circular opening, and the flow direction of the medium at the inlet 11 can be from back to front. The homogenizing structure 2 can be located directly in front of the inlet 11. Therefore, the flowing liquid can directly impact the homogenizing structure 2, thereby ensuring the impact between the liquid and the homogenizing structure 2 while reducing the loss of the liquid's kinetic energy, thus improving the homogenization effect of the liquid.

[0036] In some embodiments, the projection of the homogenizing structure 2 lies within the contour range of the projection of the inlet 11 in the flow direction. For example, as... Figure 2 As shown, the flow direction can be the front-to-back direction, the projection of inlet 11 in the front-to-back direction can be a circle, and the projection of homogenization structure 2 can be located within the circular outline of the projection of inlet 11.

[0037] This allows the fluid to flow directly to the homogenization structure 2, avoiding the loss of the fluid's kinetic energy and further enhancing the direct impact between the liquid and the homogenization structure 2, thus improving the homogenization effect.

[0038] In some embodiments, the pipe body 1 further includes an outlet 12, which is located above the inlet 11. For example, as Figure 1 and Figure 2 As shown, both inlet 11 and outlet 12 can be circular openings, the tube body 1 can be arranged vertically, both inlet 11 and outlet 12 can be located on the rear side of the tube body 1, and outlet 12 can be located directly above inlet 11.

[0039] Thus, on the one hand, the liquid needs to overcome gravity when flowing along the pipe 1, which can slow down the flow rate of the liquid and enhance the mixing effect of the dispersed liquid and gas. On the other hand, under the action of gravity, the liquid also flows back to the inlet 11, which can further prevent the liquid from entering the combustion chamber of the engine.

[0040] In some embodiments, the homogenization structure 2 includes a plurality of homogenizing elements 21, which are all fixed to the inner wall of the tube body 1 and are arranged at intervals along the extension direction of the tube body 1.

[0041] For example, such as Figure 2 As shown, there can be three homogenizing elements 21. The tube body 1 can be arc-shaped and can be bent and extended. The three homogenizing elements 21 can be arranged sequentially at intervals along the bending and extending direction of the tube body 1. In some other embodiments, there can also be two, four, five, or other homogenizing elements 21, and these homogenizing elements 21 are all arranged at intervals along the extending direction of the tube body 1.

[0042] Since the flow direction of the liquid under actual working conditions is roughly the same as the extension direction of the pipe body 1, the liquid will hit each homogenizing component 21 in sequence. Through this multiple impact, the dispersion and homogenization effect of the liquid can be improved.

[0043] In some embodiments, the plurality of homogenizing elements 21 are arranged at an angle downwards, and the angle of inclination of the plurality of homogenizing elements 21 along the extension direction tends to decrease first and then increase.

[0044] For example, such as Figure 2 As shown, the connecting pipe can be arranged vertically, and the inclination direction of the multiple homogenizing elements 21 can be consistent. For example, the multiple homogenizing elements 21 can be arranged inclined from the upper right to the lower left, and the multiple homogenizing elements 21 can be arranged at intervals in the vertical direction. In the vertical direction, the inclination angle of the multiple homogenizing elements 21 can first decrease and then increase.

[0045] This allows the homogenizing elements 21 located on the top and bottom sides to have a larger tilt angle, while the homogenizing element 21 located in the middle has a smaller tilt angle. This gradual change is beneficial for improving the homogenization effect and the turbulence effect on the liquid, thus allowing the liquid to mix more thoroughly with the gas.

[0046] In some other embodiments, the multiple homogenizing elements 21 may also be arranged at an angle from the upper left to the lower right. In other embodiments, the angle of some homogenizing elements 21 may be different from that of other homogenizing elements 21. For example, some homogenizing elements 21 may be arranged at an angle from the upper right to the lower left, and other homogenizing elements may be arranged at an angle from the upper left to the lower right.

[0047] In some embodiments, the plurality of homogenizing elements 21 include a first homogenizing element 211 and a second homogenizing element 212. The tube body 1 has a vertically arranged central axial surface 3. One end of the first homogenizing element 211 is located at or near the central axial surface 3, and the other end of the first homogenizing element 211 extends to one side of the central axial surface 3. One end of the second homogenizing element 212 is located at or near the central axial surface 3, and the other end of the second homogenizing element 212 extends to the other side of the central axial surface 3.

[0048] For example, such as Figure 2 As shown, the inclination directions of the first homogenizing member 211 and the second homogenizing member 212 can be different. The first homogenizing member 211 can be arranged inclined from the upper right to the lower left, and the second homogenizing member 212 can be arranged inclined from the upper left to the lower right.

[0049] The central axial surface 3 can be considered as a symmetrical plane of the tube body 1. When both the inlet 11 and the outlet 12 are circular, the centers of the circles corresponding to the inlet 11 and the outlet 12 can simultaneously lie on the central axial surface 3. Specifically, the central axial surface 3 can also be considered as... Figure 1 The cross-section corresponding to the connecting pipe is also known as Figure 2 A plane perpendicular to the left and right directions.

[0050] The right end of each of the first homogenizing components 211 can be located at the central axis surface 3, and the left end of each of the first homogenizing components 211 can be located on the left side of the central axis surface 3. The left end of each of the second homogenizing components 212 can be located at the central axis surface 3, and the right end of each of the second homogenizing components 212 can be located on the right side of the central axis surface 3.

[0051] By setting the different inclination directions of the first homogenizing element 211 and the second homogenizing element 212, the dispersing and homogenizing effect on the liquid can be further enhanced, thereby ensuring sufficient mixing of the liquid into the gas. Specifically, due to the different inclination directions and the interval arrangement of the first homogenizing element 211 and the second homogenizing element 212, the liquid that encounters the first homogenizing element 211 will flow to the right, and the liquid that encounters the second homogenizing element 212 will flow to the left. This allows the flow direction of the liquid to be changed multiple times, thereby enhancing the dispersing and homogenizing effect of the liquid.

[0052] In some embodiments, the angle α formed by the extending direction of the first homogenizing member 211 and the central axial surface 3 is 25° to 45°. For example, as... Figure 2 As shown, the included angle α can be 25°, 26°, 28°, 29°, 30°, 31°, 32°, 35°, 37°, 39°, 40°, 41°, 42°, 45°, etc.

[0053] Within this angle range, on the one hand, the first homogenizing element 211 can be arranged at an angle, so that a part of the liquid can flow to the right, satisfying the need to change the flow direction of the liquid. On the other hand, the first homogenizing element 211 can also have an extension component in the left and right directions, so as to ensure the blocking effect on the liquid and thus achieve the effect of dispersing the liquid.

[0054] In some embodiments, the angle b formed by the extending direction of the second homogenizing member 212 and the central axial surface 3 is 65° to 85°. For example, as... Figure 2As shown, the included angle b can be 65°, 66°, 68°, 69°, 70°, 71°, 72°, 75°, 77°, 79°, 80°, 81°, 82°, 85°, etc.

[0055] Within this angle range, on the one hand, the second homogenizer 212 can be arranged at an angle, so that a part of the liquid can flow to the left, satisfying the need to change the flow direction of the liquid. On the other hand, the second homogenizer 212 can also have an extension component in the left and right directions, so as to ensure the blocking effect on the liquid and thus achieve the effect of dispersing the liquid.

[0056] Secondly, due to the difference and variation between the tilt angle of the second homogenizer 212 and the tilt angle of the first homogenizer 211, the complexity and variability of the liquid flow direction can be enhanced, thereby further improving the homogenization effect.

[0057] In some embodiments, the vertical distance M between two adjacent homogenizing members 21 is 10 mm to 20 mm. For example, as... Figure 2 As shown, the first homogenizing element 211 can be arranged at an angle from the upper right to the lower left, and the second homogenizing element 212 can be arranged at an angle from the upper left to the lower right. The second homogenizing element 212 can be located below the first homogenizing element 211. In this case, the distance M can be the distance between the left end of the first homogenizing element 211 and the left end of the second homogenizing element 212 in the vertical direction.

[0058] The distance M can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc. Within this range, the distance M provides sufficient flow space between the first homogenizing element 211 and the second homogenizing element 212, while also preventing the distance M from being too large, thus ensuring the continuity of the flow direction change.

[0059] In some embodiments, the homogenizing member 21 includes a first extension 213 and a second extension 214, the first extension 213 and the second extension 214 being arranged at an angle to make the homogenizing member 21 herringbone. For example, as Figure 3 As shown, the first extension segment 213 can generally extend from the middle of the homogenizing member 21 in a direction to the left and rear, and the second extension segment 214 can generally extend from the middle of the homogenizing member 21 in a direction to the right and rear. This allows the homogenizing member 21 to form a herringbone-like structure, thereby further enhancing the dispersing and homogenizing effect on the liquid.

[0060] In some embodiments, the pipe body 1 is arc-shaped, and both ends of the pipe body 1 are provided with connecting flanges 13. For example, as Figure 1As shown, the pipe body 1 can be a half-circular arc pipe, and the cross-section of the pipe body 1 can be circular. The pipe body 1 can be arranged vertically, and both ends of the pipe body 1 can be integrally formed with a connecting flange 13. During assembly, the pipe body 1 can be installed and fixed through the connecting flange 13, which improves the convenience of installation.
