Description

Technical Field

[0001] This invention relates to the field of intake manifold technology, and in particular to an intake manifold and its combination method that are combined with a thermal management system and an intake system. Background Technology

[0002] In the field of modern turbocharged engine and range extender technology, the design of the intake system has a critical impact on engine performance, fuel consumption, and emissions. Currently, the widely used traditional intake system adopts a split layout, with the intake manifold and thermal management system (usually referring to the intercooler) being two independent components. The intake manifold is mostly made of cast aluminum alloy or injection molded nylon plastic, while the intercooler is usually an aluminum plate-fin structure. The two are connected by a set of long rubber or plastic pipes. The intercooler is generally located at the front of the engine and relies on the wind or a fan for cooling. The original intention of this design was to facilitate production and maintenance through modular division of labor, but it leads to high system complexity, large space occupation, and many connection points. Moreover, due to the meandering and lengthy pipes, it is easy to cause significant intake pressure loss and flow stagnation, which in turn affects the engine's transient response and charging efficiency.

[0003] Furthermore, to meet increasingly stringent emission regulations, exhaust gas recirculation (EGR) systems have become standard equipment for turbocharged engines. Existing EGR systems typically cool exhaust gases on the exhaust side using an independent external cooler before introducing them into the intake manifold via a dedicated pipeline. To filter particulate matter in the exhaust gases, particulate traps or filters are often installed in the pipeline. However, these filters gradually become clogged during operation, leading to increased back pressure and a decrease in EGR rate. The current solution is to periodically stop the engine for manual cleaning or replacement. This process not only interrupts the EGR function, potentially causing fluctuations in engine operating conditions and temporary deterioration in emissions, but also increases the user's maintenance costs and time. How to achieve uninterrupted online cleaning of the EGR system's filter unit has always been a pressing technical challenge in this field. Summary of the Invention

[0004] This invention provides an intake manifold and its combination method that are combined with a thermal management system and an intake system. It can solve the problems of system complexity, heavy weight, high pressure loss, low heat exchange efficiency and slow response caused by the split layout in the prior art. At the same time, it overcomes the technical bottlenecks of EGR system filter unit requiring shutdown for maintenance, inability to achieve online cleaning, and affecting engine stable operation and emissions.

[0005] An intake manifold combined with a thermal management system and an intake system includes: a manifold body having an intake passage extending from a high-temperature gas inlet to a low-temperature gas outlet; and a heat exchange unit installed within the manifold body, the heat exchange unit including heat dissipation fins and a coolant flow channel formed therein, the coolant flow channel having a coolant inlet and a coolant outlet; wherein the heat dissipation fins form part of the wall surface of the intake passage for cooling the intake air flowing through it.

[0006] Preferably, the manifold body includes a detachably connected intake manifold front section and intake manifold rear section, and the heat exchange unit is disposed between the intake manifold front section and intake manifold rear section.

[0007] Preferably, the front section and rear section of the intake manifold are connected to the heat exchange unit by press fitting, and a sealing ring is provided at the connection.

[0008] Preferably, the front section of the intake manifold is made of a high-temperature resistant engineering composite material, and the rear section of the intake manifold is made of an engineering composite material.

[0009] Preferably, the outer surface of the manifold body is provided with noise-reducing reinforcing ribs.

[0010] Preferably, the intake manifold is provided with an exhaust gas recirculation interface for connecting to an external exhaust gas recirculation pipeline to introduce EGR exhaust gas into the intake channel. The external exhaust gas recirculation pipeline is equipped with a filter pipeline connected thereto, the filter pipeline is equipped with a temporary flow pipeline, and the temporary flow pipeline is equipped with a first electric valve.

[0011] Preferably, the filter pipe includes a first filter half-pipe and a second filter half-pipe, the first filter half-pipe and the second filter half-pipe are connected to each other, and a spiral pipe is installed inside the first filter half-pipe.

[0012] Preferably, a bracket is installed inside the second filter half-tube, a solenoid is installed at one end of the bracket, and multiple telescopic actuators are installed around the solenoid. Multiple teardrop-shaped grooves are formed on the inner wall of the second filter half-tube, and a collection bag is installed in the teardrop-shaped groove. The collection bag is connected to the telescopic actuator.

[0013] Preferably, the filter pipe is equipped with an air inlet and a collection pipe at both ends, and a second electric valve is installed on the air inlet and the collection pipe.

[0014] The method for combining the thermal management system and the intake system into an intake manifold includes the following steps: S1: Connect the external exhaust gas recirculation pipe to the exhaust gas recirculation interface to introduce EGR exhaust gas into the intake passage through the interface; S2: Install a filter pipe on the external exhaust gas recirculation pipe, and install a temporary flow pipe with a first electric valve in parallel on the filter pipe; S3: Configure the filter pipe to include a first filter half-pipe and a second filter half-pipe connected in series, and install a spiral pipe in the first filter half-pipe. S4: Install a bracket inside the second filter half-tube, and install a solenoid and multiple telescopic actuators on the bracket; S5: Multiple teardrop-shaped grooves are opened on the inner wall of the second filter half tube, and a collection bag is installed in each teardrop-shaped groove. Each collection bag is connected to a corresponding telescopic actuator. S6: Install an air inlet and a collection pipe at both ends of the filter pipe, and install a second electric valve on the air inlet and the collection pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This solution first solves the problems of low efficiency, slow response and heavy weight of traditional split intake systems through highly integrated structural design. Specifically, the heat exchange unit is integrated into the manifold body in an embedded manner, so that the heat dissipation fins directly form the wall of the intake channel. The traditional external heat exchange path, which is several meters long, is shortened to a wall thickness of millimeters. This not only greatly reduces flow resistance and pressure loss, but more importantly, it enables rapid adjustment of intake temperature, significantly improving the thermal management accuracy and transient response capability of the engine. At the same time, the split manifold structure is adopted and high-temperature resistant and conventional recyclable engineering composite materials are selected for different working conditions of the front and rear sections respectively. Under the premise of ensuring reliability, the weight of the components is greatly reduced and the manufacturing cost is reduced. The design of press-fit connection and sealing ring further simplifies the assembly and improves the sealing reliability.

[0016] (2) This solution integrates a self-cleaning EGR filtration system, which effectively overcomes the pain point that the filter maintenance in the existing technology must be interrupted. By connecting a temporary flow pipe with a valve in parallel on the filter pipe, the EGR airflow can be switched and continuously supplied without being detected during dust removal. This allows particulate matter to be captured efficiently and achieve fully automatic, online and thorough cleaning. The whole process is completed in a closed system without human intervention. This not only ensures the stable operation and emission consistency of the EGR system throughout its entire life cycle and eliminates the interruption of operation caused by maintenance, but also greatly extends the service life of the filter unit and reduces the cost of use and maintenance throughout the entire life cycle.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figures 1 to 2 As shown in the figure, an intake manifold combined with a thermal management system and an intake system provided by an embodiment of the present invention includes: a manifold body having an intake channel extending from a high-temperature gas inlet 7 to a low-temperature gas outlet 8; a heat exchange unit 3 installed in the manifold body, the heat exchange unit 3 including heat dissipation fins 6 and a coolant flow channel formed therein, the coolant flow channel having a coolant inlet 4 and a coolant outlet 5; wherein, the heat dissipation fins 6 constitute part of the wall surface of the intake channel for cooling the intake air flowing through it.

[0021] Among them, the intake manifold provided in this solution, which is combined with the thermal management system and the intake system, is based on a highly integrated structural innovation. The intake manifold combines the traditionally independent intake channels with the liquid-cooled heat exchanger into a compact functional module.

[0022] Specifically, it includes a manifold body made of engineered composite material, which forms an intake channel extending from a high-temperature gas inlet 7 to a low-temperature gas outlet 8. A heat exchange unit 3, which includes heat dissipation fins 6 and a coolant flow channel, is directly installed and integrated inside the manifold body. The coolant flow channel is provided with a coolant inlet 4 and a coolant outlet 5.

[0023] The heat dissipation fins 6 themselves constitute part of the wall of the air intake channel, so that the heat of the high-temperature intake air entering from the high-temperature gas inlet 7 can be directly conducted through the heat dissipation fins 6 to the coolant circulating in the adjacent coolant flow channel, thereby being cooled quickly and efficiently, and finally forming low-temperature gas flowing out from the low-temperature gas outlet 8.

[0024] By utilizing the shared wall structure between the heat exchange unit 3 and the air intake channel, the heat exchange path is shortened from several meters of external pipeline in the traditional split system to a wall thickness of millimeters, achieving the ultimate minimization of the heat exchange interface and the shortest path.

[0025] This not only significantly reduces the flow resistance and pressure loss caused by long pipelines, but also improves the response speed of intake air temperature regulation by orders of magnitude, thus significantly improving the engine's transient response performance and thermal management efficiency.

[0026] The manifold body includes a detachable intake manifold front section 1 and an intake manifold rear section 2, and a heat exchange unit 3 is disposed between the intake manifold front section 1 and the intake manifold rear section 2.

[0027] The manifold body adopts a split design, including a detachable intake manifold front section 1 and intake manifold rear section 2, while the heat exchange unit 3 is located between the intake manifold front section 1 and intake manifold rear section 2.

[0028] The front section 1 of the intake manifold directly bears the high-temperature gas from the turbocharger, so it is made of high-temperature resistant engineering composite material; while the rear section 2 of the intake manifold can be made of conventional engineering composite material.

[0029] This segmented material selection achieves an optimal balance between function and cost: the material of the front section 1 of the intake manifold is designed to withstand high temperatures and thermal stress, ensuring structural reliability; while the material of the rear section 2 of the intake manifold focuses on economy and lightweighting.

[0030] While ensuring performance in key areas, the overall manufacturing cost is effectively controlled, and the lightweight characteristics of composite materials are fully utilized, which can reduce weight compared to all-metal manifolds, thus helping to reduce vehicle fuel consumption and emissions.

[0031] The intake manifold front section 1, intake manifold rear section 2, and heat exchange unit 3 are connected by press fitting, and a sealing ring 9 is provided at the connection.

[0032] In order to achieve reliable sealing and connection, the intake manifold front section 1, intake manifold rear section 2 and heat exchange unit 3 are connected by press fitting, and a sealing ring 9 is provided at the connection.

[0033] During assembly, the sealing ring 9 is first installed in the sealing groove of the heat exchange unit 3, and then the front section 1 of the intake manifold, the rear section 2 of the intake manifold, and the heat exchange unit 3 are pressed together by the crimping tool.

[0034] By utilizing the elastic deformation and interference fit of the material, axial pressure is applied to make the components fit tightly together, and the micro gaps are filled by the sealing ring 9.

[0035] This stable, reliable, and relatively simple structural connection replaces a large number of flanges, bolts, and rubber hoses in traditional systems.

[0036] This not only eliminates multiple potential leakage points and improves the airtightness and reliability of the system, but also significantly reduces the number of parts and assembly complexity, thereby reducing production and assembly costs and meeting the automotive industry's pursuit of modular and low-cost manufacturing.

[0037] The front section 1 of the intake manifold is made of high-temperature resistant engineering composite material, and the rear section 2 of the intake manifold is made of engineering composite material.

[0038] Among them, high-temperature resistant engineering composite materials and engineering composite materials both belong to the recyclable thermoplastic polymer material system. High-temperature resistant engineering composite materials can be composite materials with glass fiber reinforced polyphthalamide as the main component; engineering composite materials can be composite materials with glass fiber reinforced polyamide 66 as the main component.

[0039] The high-temperature resistant engineering composite material in the front section 1 of the intake manifold must have the characteristics of high strength, high heat resistance and low thermal conductivity, so that it can directly withstand the thermal load and mechanical load from the high temperature and high pressure intake air from the turbocharger, and ensure the dimensional stability and structural integrity of the component under extreme conditions.

[0040] Meanwhile, its low thermal conductivity helps reduce the secondary heating of the cooled intake air caused by the high temperature environment in the engine compartment, providing a reliable material basis for the entire system while meeting the stringent working environment requirements of the front end.

[0041] The engineering composite material used in the rear section 2 of the intake manifold needs to meet the mechanical strength and chemical corrosion resistance required by subsequent processes, while its molding processability and economy are optimized.

[0042] While ensuring functionality, lightweighting is achieved, with a density far lower than that of traditional aluminum alloys, which helps to reduce the overall weight of the components. Furthermore, through the one-piece molding process, a more complex and streamlined internal air passage model can be manufactured than that produced by metal casting, further optimizing airflow and reducing flow loss.

[0043] The recyclability feature is reflected in the fact that after the product life cycle ends, the materials of the front section 1 and the rear section 2 of the intake manifold can be crushed, melted and reused to produce other non-critical structural parts. This feature runs through the entire product life cycle, which is in line with the principles of circular economy and green manufacturing and reduces environmental impact.

[0044] The outer surface of the manifold body is provided with noise reduction reinforcing ribs 11.

[0045] The outer surface of the manifold body is usually designed with noise reduction reinforcing ribs 11. The layout, width and height of these noise reduction reinforcing ribs 11 are not set arbitrarily, but are analyzed and optimized through joint simulation of computational fluid dynamics and structural mechanics.

[0046] The optimized noise-reducing reinforcing rib 11 can effectively change the structural mode of the manifold shell, suppress vibrations at specific frequencies, and disrupt the resonance that may occur in the airflow near the wall.

[0047] It can significantly enhance the structural rigidity of the manifold body and improve its durability in engine vibration environment; at the same time, as a passive noise reduction method, it effectively reduces the noise generated by the intake system, improves the NVH performance of the whole vehicle, and thus improves the user's driving comfort and satisfaction.

[0048] like Figures 3 to 5 As shown, the intake manifold 2 is provided with an exhaust gas recirculation interface for connecting to an external exhaust gas recirculation pipe 20 to introduce EGR exhaust gas into the intake channel. The external exhaust gas recirculation pipe 20 is equipped with a filter pipe 30 connected to it. A temporary flow pipe 31 is installed on the filter pipe 30, and a first electric valve is installed on the temporary flow pipe 31.

[0049] The filter pipe 30 includes a first filter half-pipe 40 and a second filter half-pipe 50, which are connected together. A spiral pipe is installed inside the first filter half-pipe 40.

[0050] A bracket 51 is installed inside the second filter half-tube 50. A solenoid 52 is installed at one end of the bracket 51. Multiple telescopic actuators 53 are installed around the solenoid 52. Multiple teardrop-shaped grooves 54 are opened on the inner wall of the second filter half-tube 50. A collection bag 55 is installed in the teardrop-shaped groove 54. The collection bag 55 is connected to the telescopic actuator 53.

[0051] The filter pipe 30 is equipped with an air inlet 32 ​​and a collection pipe 33 at both ends, and a second electric valve is installed on the air inlet 32 ​​and the collection pipe 33.

[0052] The intake manifold 2 is equipped with an exhaust gas recirculation interface for connecting to an external exhaust gas recirculation pipe 20 to introduce EGR exhaust gas into the intake channel. The external exhaust gas recirculation pipe 20 is equipped with a filter pipe 30 connected thereto. A temporary flow pipe 31 is connected in parallel to the filter pipe 30. A first electric valve is installed on the temporary flow pipe 31.

[0053] This layout solves the traditional problem that EGR systems must be interrupted during filter maintenance. By setting up parallel filter pipes 30 and temporary flow pipes 31, and controlling the flow direction with a first electric valve, the system can instantly switch exhaust gas to flow through the temporary flow pipes 31 when the filter pipes 30 are self-cleaning. This ensures a continuous supply of EGR airflow, avoids engine operating condition fluctuations or emission deterioration caused by maintenance, and achieves true online maintenance.

[0054] The filter pipe 30 includes a first filter half-pipe 40 and a second filter half-pipe 50 connected in series along the airflow direction. A spiral pipe is fixedly installed inside the first filter half-pipe 40. After the EGR exhaust gas enters the first filter half-pipe 40, it is forced to rotate and flow along the spiral pipe, generating a strong centrifugal force.

[0055] Under this centrifugal force, the solid particles in the exhaust gas, mainly carbon soot, are accelerated and thrown towards the outer pipe wall due to their large mass. This effectively pre-separates and screens the particulate matter, creating conditions for subsequent high-efficiency capture and improving the overall filtration efficiency.

[0056] like Figures 6 to 7 As shown, a bracket 51 is installed inside the second filter half-tube 50, a solenoid 52 is installed on the bracket 51, and multiple telescopic actuators 53 are arranged circumferentially around the solenoid 52. Multiple teardrop-shaped grooves 54 are opened on the inner wall of the second filter half-tube 50, and a collection bag 55 made of flexible material is placed in each teardrop-shaped groove 54. The collection bag 55 is connected to the corresponding telescopic actuator 53.

[0057] First, the particles accelerated by centrifugation through the spiral pipe are swept into the collection bag 55 of the teardrop-shaped groove 54 by inertia and captured. Second, when dust removal is required, the control system is activated, the solenoid 52 is energized to provide auxiliary magnetic force, and at the same time the designated telescopic actuator 53 moves to precisely pull the collection bag 55 out of the groove and flip it over, realizing efficient and directional capture and storage of particles, and providing a reliable execution basis for subsequent mechanized automatic dust removal.

[0058] It should be noted that the design of the teardrop-shaped groove 54, with its large internal cavity volume and narrow opening facing the inner cavity of the pipe, aims to provide ample dust-holding space for the collection bag 55. At the same time, the narrow opening forms a throat structure, which is beneficial to utilizing the principles of gas dynamics. When a high-speed airflow carrying particles flows close to the pipe wall, a local low pressure or turbulence is easily formed at the narrow opening, which can more effectively introduce particles into the groove.

[0059] At the same time, this structure can significantly reduce the probability of particles being re-swept away by the mainstream airflow after they enter, achieving a capture effect that makes it easy for particles to enter but difficult for them to exit. Based on the synergistic effect of the centrifugal force and the special structure of the teardrop-shaped groove 54, the solid particles that are thrown against the pipe wall will directly collide with and rush into the opening of the teardrop-shaped groove 54 when they move along the pipe wall at extremely high tangential velocity, thus efficiently entering the collection bag 55.

[0060] The collection bag 55 is preferably made of special silicone rubber or fluororubber that is heat resistant, i.e. can withstand temperatures greater than 200°C for a long time, is oil resistant, and has a certain degree of flexibility, so as to ensure its reliability in long-term operation in high-temperature exhaust gas environments.

[0061] To further enhance the anti-adhesion and wear-resistant properties of its surface, a low surface energy coating, such as a polytetrafluoroethylene coating, can be applied to the inner surface of the collection bladder 55. This coating can effectively reduce the adhesion of particles to the bladder wall and ensure that the particles can be completely and smoothly removed from the inside of the bladder during dust removal and purging.

[0062] The telescopic actuator 53 has the following structure: it includes a non-magnetic slide cylinder fixed on the bracket 51, and a magnetic rod is slidably fitted inside the slide cylinder. The magnetic rod is connected to the collection bag 55.

[0063] Inside the slide tube, at the bottom of the magnetic rod, there is an elastic element, such as a helical compression spring or an elastic rubber strip. Under normal conditions, this elastic element applies an elastic support force to the magnetic rod in the direction of the tube wall, that is, the direction in which the collection bag 55 is embedded in the groove, so that the collection bag 55 is stably attached to the teardrop-shaped groove 54.

[0064] When the dust removal action is required, the solenoid 52 is energized, generating a strong magnetic attraction force opposite to the direction of the elastic force. This attracts the magnetic rod to overcome the supporting force of the elastic element and slide towards the solenoid 52, thereby accurately pulling the collection bag 55 out of the teardrop-shaped groove 54 and flipping it over. This is existing technology and will not be described in detail here.

[0065] The filter pipe 30 is provided with an air inlet 32 ​​and a collection pipe 33 at both ends. A second electric valve is installed on both the air inlet 32 ​​and the collection pipe 33. When the dust removal program is triggered, the control system first closes the first electric valve located on the temporary circulation pipe 31, and at the same time opens the second electric valves on the air inlet 32 ​​and the collection pipe 33.

[0066] When the first electric valve is closed, the main EGR exhaust gas flow is instantly and seamlessly guided to the parallel temporary flow pipe 31 for continued delivery, thereby ensuring that the EGR exhaust gas supply to the engine is uninterrupted throughout the process and avoiding engine operating condition fluctuations or emission interruptions caused by filter unit maintenance.

[0067] It is worth noting that a basic filter is also installed inside the temporary flow duct 31. This design solves the problem that exhaust gas may enter the engine directly without treatment during online cleaning. The basic filter can replace the main filter duct 30 in a short time to play a basic particulate matter interception role and ensure the basic cleanliness of the exhaust gas during cleaning.

[0068] While achieving deep self-cleaning of the main filtration system, it ensures the quality of exhaust gas treatment at all times and throughout the entire process, improving the overall reliability and emission consistency of the system.

[0069] After the filter pipe 30 is isolated from the main airflow, the dust removal procedure is executed. At this time, the high-speed airflow from the vehicle's driving wind or external air source can be used to enter the filter pipe 30, which is isolated from the main airflow, from the air inlet 32 ​​to perform a reverse powerful blow to the inside of the collection bag 55, which has been flipped over by the telescopic actuator 53.

[0070] The blown-out particulate clumps enter the collection pipe 33 with the airflow. The fine filter installed in the pipe allows air to pass through but effectively traps and collects the particulate matter in the attached dust collection box. After the purging is completed, the telescopic actuator 53 drives the clean collection bag 55 to reset, all valve states are restored, the EGR main airflow flows through the newly refreshed filter pipe 30 again, and the system continues to work.

[0071] In summary, this integrated self-cleaning system achieves fully automatic, online, and deep cleaning of the filter unit through a synergistic mechanism of seamless airflow switching, backup filtration, and combined mechanical and pneumatic cleaning. It requires no manual intervention, and the cleaning is thorough, restoring the filter unit to its initial performance. The backup of the temporary flow duct 31 and its built-in filter ensures a continuous and stable supply of EGR airflow to the engine and a basic filtration effect, with no risk of operation interruption throughout the process. Third, the entire dust removal and collection process is completed within a closed system, avoiding secondary pollution from particulate matter. Ultimately, this system greatly extends the maintenance cycle of the core filter unit, improves the long-term operational reliability of the EGR system and even the entire engine, and significantly reduces the maintenance cost throughout the entire life cycle.

[0072] The method for combining the thermal management system and the intake system into an intake manifold includes the following steps: S1: Connect the external exhaust gas recirculation pipe 20 to the exhaust gas recirculation interface to introduce EGR exhaust gas into the intake passage through the interface; S2: Install a filter pipe 30 on the external exhaust gas recirculation pipe 20, and install a temporary flow pipe 31 with a first electric valve in parallel on the filter pipe 30; S3: Configure the filter pipe 30 to include a first filter half-pipe 40 and a second filter half-pipe 50 connected in series, and install a spiral pipe in the first filter half-pipe 40. S4: Install a bracket 51 inside the second filter half-tube 50, and install a solenoid 52 and multiple telescopic actuators 53 on the bracket 51; S5: Multiple teardrop-shaped grooves 54 are opened on the inner wall of the second filter half tube 50, and a collection bag 55 is installed in each teardrop-shaped groove 54. Each collection bag 55 is connected to a corresponding telescopic actuator 53. S6: Install an air inlet 32 ​​and a collection pipe 33 at both ends of the filter pipe 30, and install a second electric valve on the air inlet 32 ​​and the collection pipe 33.

Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
