Description

TECHNICAL FIELD

[0001] The utility model relates to a middle cooler connecting structure, especially to a spliced middle cooler connecting structure. BACKGROUND

[0002] The middle cooler is a very important component in the turbocharged engine, and its main function is to cool the high-temperature compressed air from the turbocharger to improve the air density, thereby increasing the oxygen content entering the engine, improving the combustion efficiency and the performance of the engine; The middle cooler connecting structure, i.e. the middle cooler pipe, is a pipeline for connecting the middle cooler and the engine, and the function of this part of the pipeline is to deliver the air cooled by the middle cooler to the intake manifold of the engine. In order to ensure efficient gas flow and cooling effect, the middle cooler pipe is usually designed as straight as possible and made of materials that can withstand high pressure and high temperature, which helps to reduce air resistance, improve the intake efficiency of the engine, and thus improve the overall performance.

[0003] The existing middle cooler pipe is usually connected with other components (such as the middle cooler, the intake manifold, the turbocharger, etc.) using a single ear clamp. The single ear clamp adjusts the tightness through threads and screws, which is a simple, economical and effective connection method. However, there are still some potential drawbacks when fixing the middle cooler pipe, such as the existence of small gaps at the clamp connection, which may cause air leakage, especially in high temperature and high pressure environments, the problem of insufficient sealing is more prominent. The engine and the turbocharger will vibrate when working, and these vibrations may cause the clamp to loosen, especially when the clamp is not fully tightened. Long-term vibration may cause fatigue damage to the clamp and the connection part, further affecting the sealing and the reliability of the connection.

[0004] Therefore, it is necessary to design a spliced middle cooler connecting structure to solve the above technical problems. UTILITY MODEL CONTENTS

[0005] In order to overcome the shortcomings of the above background technology, the technical problem of the utility model is to provide a spliced middle cooler connecting structure.

[0006] The utility model discloses a technical implementation scheme for a spliced intercooler connecting structure, which comprises air guide pipes, intercoolers, reinforcing ribs, fixing rings, clamps, double-layer sealing rings, first sealing pipes, second sealing pipes, turbochargers and intake manifolds. The intercoolers are clamped to the sides of the air guide pipes away from each other. The reinforcing ribs are fixed to the outer walls of the intercoolers. First threaded grooves are formed in the outer walls of the two ends of each reinforcing rib. The turbocharger is clamped to one end of the right intercooler. The intake manifold is clamped to one end of the left intercooler. The first sealing pipes are fixed to the ends of the air guide pipes away from each other. The first sealing pipes are fixed to the ends of the turbocharger and the intake manifold. The second sealing pipes are threadedly connected to the outer walls of the two ends of each reinforcing rib. The inner grooves of each second sealing pipe are matched with the first threaded grooves on the same side. Second threaded grooves are formed in the outer walls of each second sealing pipe. The inner grooves of each second threaded groove are matched with the first sealing pipes on the same side. The fixing rings are fixed to the upper and lower sides of each reinforcing rib. The clamps are slidably connected to the middle parts of the fixing rings. The two clamps on the upper side are clamped to the air guide pipes on the same side. The two clamps on the lower side are clamped to the air outlet of the turbocharger and the air inlet of the intake manifold. The double-layer sealing rings are fixed to the inner walls of the air guide pipes at the tight connection positions with the intercoolers on the same side. The bottom of the right intercooler is tightly connected to the top of the turbocharger, and the double-layer sealing ring is fixed to the inner wall at the tight connection position. The bottom of the left intercooler is tightly connected to the top of the intake manifold, and the double-layer sealing ring is fixed to the inner wall at the tight connection position.

[0007] As an improvement of the above-mentioned scheme, the utility model also includes shock absorbers, protective rings, screws and nuts. The shock absorbers are fixed to the upper part of the turbocharger. The protective rings are fixed to the outer walls of the shock absorbers. The inner walls of the two protective rings are in close contact. The screws are threadedly connected to the two sides of the protective rings. The nuts are threadedly connected to the rear sides of the screws.

[0008] As an improvement of the above-mentioned scheme, the utility model also includes sealing air bags. The sealing air bags are fixed to the inner walls of the fixing rings.

[0009] As an improvement of the above-mentioned scheme, the utility model also includes pressure relief valves and intake temperature and pressure sensors. The pressure relief valves are connected to the outer walls of the right intercooler and the reinforcing rib and communicate with each other. The intake temperature and pressure sensor is fixed to one side of the intake manifold.

[0010] As an improvement of the above-mentioned scheme, the material of the intercooler is aluminum alloy.

[0011] As an improvement of the above-mentioned scheme, the material of the reinforcing rib is high-density polyethylene (PE).

[0012] The utility model has the following advantages: 1. The utility model clamps and fixes the air guide pipe by cooperating with the clamp and the fixing ring, so that the intercooler pipe and the reinforcing ribs and other components are effectively connected. The first sealing pipe and the second sealing pipe are threadedly connected to form a closed ventilation duct, thereby achieving the effect of quickly splicing the intercooler. At the same time, the intercooler pipe is not prone to rupture, deformation and falling off, which effectively extends the service life of the intercooler pipe.

[0013] 2. The utility model provides double-layer sealing rings at the connection between the air duct and the intercooler pipe, the connection between the intercooler pipe and the turbocharger outlet, and the connection between the intercooler pipe and the intake manifold, which can effectively prevent gas leakage inside the ventilation pipe and minimize the risk.

[0014] 3. The present invention controls the boost pressure of the turbocharger through a pressure relief valve. When the boost pressure reaches a preset value, the pressure relief valve is opened, allowing part of the exhaust gas to bypass the turbine and be discharged directly into the exhaust system, thereby reducing the turbine speed and boost pressure inside the turbocharger, effectively preventing the boost pressure from being too high, and protecting the turbocharger and other related components from damage.

The upper ends of the turbocharger 13 and the intake manifold 14 are A first sealing tube 8 is heat-welded, and the outer walls of the upper and lower ends of the two reinforcing ribs 4 are threadedly connected to the second sealing tube 9. The inner grooves of the four second sealing tubes 9 are consistent with the first thread groove 401 on the same side. The outer walls of the four second sealing tubes 9 are each provided with a second thread groove 901, and the four second thread grooves 901 are consistent with the inner grooves of the first sealing tube 8 on the same side. Fixed rings 5 ​​are welded on the upper and lower sides of the two reinforcing ribs 4. The middle parts of the four fixing rings 5 ​​are slidably connected to clamps 6. The two clamps 6 on the upper side are clamped with the air guide tube 2 on the same side. The two clamps 6 on the lower side are respectively connected to the air outlet of the turbocharger 13 and the air inlet of the intake manifold 14. The inner walls of the two air guide pipes 2 and the intercooler pipe 3 on the same side are bonded with double-layer sealing rings 7 through sealant. The bottom of the right intercooler pipe 3 is tightly connected to the top of the turbocharger 13, and the inner walls of the two places where the two are tightly connected are bonded with double-layer sealing rings 7 through sealant. The bottom of the left intercooler pipe 3 is tightly connected to the top of the intake manifold 14, and the inner walls of the two places where the two are tightly connected are bonded with double-layer sealing rings 7 through sealant.

[0026] like Figures 1-2 、 Figures 4-5 and Figure 8 As shown, it also includes a sealing airbag 10, a pressure relief valve 11, a shock absorber 12, a protective ring 1201, screws 1202, nuts 1203 and an intake air temperature and pressure sensor 15. The inner walls of the four fixing rings 5 ​​are bonded with the sealing airbags 10 by sealant, the shock absorber 12 is installed on the upper part of the turbocharger 13 by screws, and the outer wall of the shock absorber 12 is connected to two protective rings 1201 by screws. The inner walls of the two protective rings 1201 are in close contact, and the left and right sides of the two protective rings 1201 are threadedly connected to the screws 1202, and the rear sides of the two screws 1202 are threadedly connected to the nuts 1203. The outer walls of the right intercooler pipe 3 and the reinforcement rib 4 are connected and connected to the pressure relief valve 11, and the left side of the intake manifold 14 is connected to the intake air temperature and pressure sensor 15 by screws.

[0027] When it is necessary to use the spliced ​​intercooler connection structure, all the parts to be assembled are first gathered together; in the initial state, the outer wall of each air duct 2 is welded with a first sealing tube 8, the outer wall of the turbocharger 13 and the intake manifold 14 are welded with a first sealing tube 8, the fixing ring 5 and the clamp 6 work together to form a clamping structure, the intercooler pipe 3 and the reinforcing rib 4 are in a fixed state, and the upper and lower sides of each reinforcing rib 4 are welded with a fixing ring 5, the pressure relief valve 11 is connected and communicated with the air duct 2 and the intercooler pipe 3 on the right side, and the intake air temperature and pressure sensor 15 is installed on the left side of the intake manifold 14; the user first places the intercooler body 1 on the desktop, then connects and communicates each air duct 2 with the intercooler body 1, and then the user puts each The double-layer sealing ring 7 is placed on the inner wall of the intercooler pipe 3 on the same side, so that the outer wall of each double-layer sealing ring 7 is tightly fitted with the inner wall of the intercooler pipe 3 on the same side. Then the user fixes each blocking airbag 10 to the fixing ring 5 on the same side, so that the outer wall of each blocking airbag 10 is tightly fitted with the inner wall of the fixing ring 5 on the same side, and ensures that the blocking airbag 10 is fully inflated. Then the user first makes the upper and lower ends of each reinforcing rib 4 threadedly connected to the second sealing tube 9, and then the user first clamps the clamp 6 with the upper air guide pipe 2, so that under the clamping action of the clamp 6, the intercooler pipe 3 and the reinforcing rib 4 and other components are spliced ​​together with the air guide pipe 2 to form a semi-closed air guide channel, and then the user respectively clamps the clamp 6 with the turbocharger 13 and the intake The outer wall of the manifold 14 is snap-fitted to form a completely enclosed air guide channel. At this time, the left side of the intercooler pipe 3 on the right is in close contact with the right side of the right air guide pipe 2. Similarly, the right side of the intercooler pipe 3 on the left is in close contact with the left side of the left air guide pipe 2, and the double-layer sealing ring 7 is located on the inner wall of the tight connection between the intercooler pipe 3 and the air guide pipe 2 on the same side, effectively preventing air leakage at the joint between the two and achieving a one-time sealing effect. Then the user rotates the four second sealing tubes 9 respectively, causing each second sealing tube 9 to be threadedly connected to the first sealing tube 8 on the same side. At the same time, in the process of each second sealing tube 9 approaching the first sealing tube 8 on the same side, each second sealing tube 9 will resist the clamp 6 on the same side to prevent the clamp 6 from loosening, thereby effectively preventing the air guide pipe from being loosened. The trachea 2 is disconnected from the intercooler pipe 3. At this time, under the action of the blocking airbag 10, there will be no air leakage between the first sealing tube 8 and the second sealing tube 9, achieving a secondary sealing effect; after all the above components are assembled, the user puts the shock absorber 12 on the outer wall of the turbocharger 13 and wraps the shock absorber 12 with two protective rings 1201. At this time, it should be ensured that the through holes of the two shock absorbers 12 are aligned, and then the two screws 1202 are respectively passed through the aligned through holes, and then the two nuts 1203 are respectively fixed to the screws 1202 by other tools, so that the shock absorber 12 is fixed to the outer wall of the turbocharger 13. At this time, all component assembly work is completed, and the user can connect the entire connection structure to the car engine, etc.

[0028] When the car is in motion, the turbocharger 13 uses the exhaust gas discharged by the engine to drive a turbine, which is connected to a compressor impeller. When the exhaust gas flows through the turbine, it rotates the turbine, which in turn drives the compressor impeller to rotate. The compressor impeller inhales air from the outside and compresses it, and then sends the compressed air to the intercooler through the intercooler pipe 3. The intercooler cools the compressed air, increases the air density, allows more oxygen to enter the engine, and improves combustion efficiency. The cooled air then enters another intercooler pipe 3, and is then sent to the intake manifold 14 through the intercooler pipe 3. The intake manifold 14 is responsible for distributing the air cooled by the intercooler to each cylinder, while ensuring that each cylinder can obtain a uniform and appropriate amount of new air. Fresh air is supplied to achieve the effect of maintaining efficient operation of the engine. During the above working process, each double-layer sealing ring 7 plays a sealing role, effectively preventing gas leakage at the connection points of each pipeline. At the same time, with the cooperation of the first sealing tube 8, the second sealing tube 9 and the blocking airbag 10 at each location, a secondary seal is formed to enhance the sealing performance of the connection structure under working conditions. The turbocharger 13 will generate vibration and resonance when running at high speed. At this time, the shock absorber 12 can effectively reduce and control the vibration and resonance, effectively reduce the fatigue and wear of the turbocharger 13 and its connecting parts, and extend its service life. At the same time, the vibration is reduced, which significantly reduces the noise generated by the turbocharger 13 during operation, providing a quieter driving experience.

[0029] When the boost pressure of the turbocharger 13 reaches a preset value, the vehicle control system opens the pressure relief valve 11, allowing part of the exhaust gas to bypass the turbocharger 13 and be discharged directly into the exhaust system, thereby reducing the speed and boost pressure of the turbine inside the turbocharger 13, preventing the boost pressure from being too high, thereby protecting the turbocharger 13 and other related components from damage, and ensuring that the engine operates within a safe pressure range; when the cooled air is sent into the intake manifold 14, the intake air temperature and pressure sensor 15 monitors the air temperature entering the intake manifold 14, that is, the intake air temperature and pressure sensor 15 adjusts the fuel injection amount according to the intake air temperature. At the same time, because high-temperature intake air may cause knock (abnormal combustion phenomenon in the engine), the intake air temperature and pressure sensor 15 can also prevent knock by adjusting the ignition timing and fuel injection amount.

[0030] Although the present disclosure has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
