Description

Technical Field

[0001] The utility model relates to the field of automobile turbines, in particular to a high-temperature resistant engine turbocharger pipe. Background Art

[0002] A turbocharger consists of two main parts: the turbine and the compressor. The turbine is located in the exhaust duct, through which the exhaust gas from the engine flows. The energy of the exhaust gas rotates the turbine, which is connected to the compressor shaft. The compressor is located in the intake duct, and it compresses the outside air and feeds it into the engine.

[0003] The intercooler is located between the compressor and the engine. Its function is to reduce the temperature of the high-temperature compressed air. Specifically, the intercooler cools the compressed air by dissipating heat, thereby increasing the air density. This helps increase the engine's air intake, improving combustion efficiency and performance.

[0004] At present, a Chinese patent with authorization announcement number CN215633450 discloses a turbocharger pipe, including an intake pipe, the outer surface of the intake pipe is fixedly connected to a heat dissipation coil, the inner wall of the intake pipe is fixedly connected to a fixing frame, the upper surface of the fixing frame is fixedly connected to an intake fan, the inner wall of the intake pipe is provided with two connecting through holes, the interior of the two connecting through holes is jointly hinged with a rotating column, the outer surface of the rotating column is fixedly connected to a baffle, and the inner wall of the intake pipe is fixedly connected to a slag baffle.

[0005] However, the existing turbocharger pipe is usually made of silicone material by injection molding, and there is usually an uneven convex ring at the bend, which will affect the smoothness of the airflow. Utility Model Content

[0006] In view of this, the utility model aims to provide a high temperature resistant engine turbocharger pipe to achieve the purpose of improving the smoothness of air flow.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a high-temperature resistant engine turbocharger pipe, including a tube body made of silicone, the tube body including an inlet pipe and an outlet pipe, the inlet pipe is connected to the middle of the outlet pipe, a transition ring sleeve is arranged on the inner wall of the outlet pipe, a guide arc surface is provided at one end of the transition ring sleeve close to the opening of the outlet pipe, a placement arc surface is provided at one end of the transition ring sleeve close to the inlet pipe, the placement arc surface is located outside the convex ring, and the transition ring sleeve is connected to the outlet pipe by a positioning structure.

[0008] To implement the above technical solution, air is introduced from the air inlet pipe and then discharged from the air outlet pipe, a transition ring sleeve is placed on the inner wall of the air outlet pipe, and the transition ring sleeve is fixed to the inner wall of the air outlet pipe by a positioning structure. By setting a protective arc surface, the air can be guided to the transition ring sleeve along the convex ring, and finally, the air is smoothly transferred to the inner wall of the air outlet pipe along the placement arc surface, so that the air can flow smoothly in the pipe body.

[0009] As a preferred solution of the utility model, the positioning structure includes a guide groove, an installation groove, a spring sheet and a guide rod. The guide groove is opened on the outer wall of the transition ring sleeve, and the length direction of the guide groove is arranged along the axial direction of the transition ring sleeve. The installation groove is opened on the inner wall of the air outlet pipe, and the two ends of the spring sheet are fixed on the inner wall of the installation groove. The middle part of the spring sheet is fixedly connected to the guide rod, and the guide rod is slidably connected to the installation groove and is used to be embedded in the guide groove.

[0010] To implement the above technical solution, the transition ring sleeve is moved from the end of the air outlet pipe toward the direction close to the air inlet pipe, and the guide rod is pressed into the installation groove. When the end of the transition ring sleeve moves above the installation groove, the guide rod is released so that the guide rod contacts the outer wall of the transition ring sleeve. As the transition ring sleeve continues to move, when the guide groove corresponds to the guide rod, the guide rod is embedded in the guide groove through the elastic force of the elastic member to achieve the positioning of the transition ring sleeve. The guide rod contacts the inner wall of the guide groove to limit the rotation and movement of the transition ring sleeve, thereby achieving the positioning function of the transition ring sleeve.

[0011] As a preferred solution of the utility model, a guiding inclined surface is provided at the end of the guiding rod, and the end of the transition ring sleeve is used to abut against the guiding inclined surface.

[0012] To implement the above technical solution, the transition ring sleeve is moved toward the direction close to the air intake pipe, and the end of the transition ring sleeve contacts the guide slope, so that the guide rod can move into the installation groove by itself, thereby improving the convenience of installation.

[0013] As a preferred solution of the utility model, a guide rod is fixedly connected to the inner wall of the installation groove, a guide hole is opened on the guide rod, and the guide rod is slidably connected to the guide hole.

[0014] To implement the above technical solution, when the airflow passes through the transition ring sleeve, the guide rod is slidably connected to the guide hole so that the guide rod can only move along the length direction of the guide rod, so that the transition ring sleeve is not prone to swing, thereby greatly improving the smoothness of the airflow.

[0015] As a preferred solution of the utility model, the outer wall of the tube body is coated with a reinforcement layer.

[0016] Implementing the above technical solution enables the pipe body to withstand high temperature and high pressure working environment and improves its service life.

[0017] As a preferred solution of the utility model, the reinforcement layer includes a silicone rubber layer and an aramid fiber layer, the aramid fiber layer is arranged in a cross shape and is located inside the silicone rubber layer, and the silicone rubber layer is coated on the outer wall of the tube body.

[0018] To implement the above technical solution, the silicone rubber layer has excellent high temperature resistance, and the setting of the aramid fiber layer increases the strength of the tube body. After adding the aramid fiber layer to the silicone rubber layer, it can not only protect the aramid fiber layer, but also make the tube body have good flexibility and high temperature resistance, so as to adapt to the vibration of the engine and high temperature air.

[0019] As a preferred solution of the utility model, one end of the air outlet pipe has a bending portion.

[0020] The above technical solution is implemented to facilitate connection with other devices to improve practicality. BRIEF DESCRIPTION OF THE DRAWINGS
