Abstract
Description
Technical Field
[0001] This utility model relates to the field of engine intake bend technology, and in particular to a high-temperature resistant engine intake bend. Background Technology
[0002] The engine intake manifold is part of the car's intake system. When air flows through the intake port, the bending of the pipe causes changes in speed and direction, thus drawing air into the engine and ensuring smooth airflow so that the engine can operate normally.
[0003] However, in the existing technology, the airflow drawn into the existing engine intake bend is chaotic when it is working. The irregular airflow will collide with the pipe wall after entering the intake bend, which will lead to noise. In addition, the existing intake bend has a thin pipe wall. After the airflow collides with the pipe wall, it will cause the pipe to resonate, which will cause the intake bend to make a buzzing sound and generate noise. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-temperature resistant engine intake bend.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-temperature resistant engine intake bend, comprising: an intake bend body, a noise reduction mechanism disposed on the outer side of the intake bend body, a heat dissipation mechanism disposed on the outer side of the noise reduction mechanism, the intake bend body including a mounting component, a pipe body disposed at the lower end of the mounting component, an mounting ring disposed at the lower end of the pipe body, the noise reduction mechanism including a positioning component, a sealing ring disposed at the lower end of the positioning component, three positioning holes arranged in a circular equidistant array disposed at the upper end of the sealing ring, a conical opening disposed at the lower end of the positioning holes, a sealing groove disposed on the outer side of the conical opening, three reinforcing ribs arranged in a circular equidistant array disposed at the lower end of the sealing groove, a resonator disposed at the front end of the reinforcing ribs, and a rectifier disposed at the upper end of the resonator.
[0006] In a preferred embodiment, the heat dissipation mechanism includes heat dissipation fins, and two sets of symmetrical heat dissipation fins are provided on the outer side of the tube body. Each set of heat dissipation fins has two fins, and the inner side of the heat dissipation fins is fixedly connected to the outer side of the tube body.
[0007] In a preferred embodiment, the upper end of the tube is provided with three mounting members arranged in a circular equidistant array, the rear end of the mounting members is fixedly connected to the upper end of the tube, and the inner side of the mounting ring is fixedly connected to the lower end of the tube.

[0009] In a preferred embodiment, the outer side of the conical opening is fixedly connected to the top of the tube body, the opening of the conical opening is larger on the side closer to the positioning member, and a sealing groove is provided on the side of the tube body closer to the sealing ring.
[0010] In a preferred embodiment, the lower end of the sealing ring is fixedly connected to the upper end of the tube, the inner side of the reinforcing rib is fixedly connected to the outer side of the tube, and the rear end of the resonator is fixedly connected to the front end of the tube.
[0011] In a preferred embodiment, the resonator has a cavity communicating with the tube body on its inner side, the rectifier is fixedly connected to the tube body near the top side on its outer side, and the rectifier has multiple rectifier holes at its lower end.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention seals the air inlet of the intake bend through the double sealing effect of the sealing ring and sealing groove, reducing the escape of the airflow drawn in by the intake bend.

The conical opening allows the airflow to enter the pipe relatively smoothly, preventing the airflow from entering the pipe chaotically and colliding with the pipe wall. The flow straightener can divide the incoming airflow, breaking it into countless small and orderly streams. The heat dissipation fins can increase the contact area between the pipe and the air, resulting in better cooling and heat dissipation. The entire pipe is made of aluminum alloy, which has good thermal conductivity and strong heat resistance. Attached Figure Description

Example
[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a high-temperature resistant engine intake bend, comprising: an intake bend body 1, a noise reduction mechanism 2 disposed on the outer side of the intake bend body 1, a heat dissipation mechanism 3 disposed on the outer side of the noise reduction mechanism 2, the intake bend body 1 including a mounting component 11, a pipe body 12 disposed at the lower end of the mounting component 11, and a mounting ring 13 disposed at the lower end of the pipe body 12, the noise reduction mechanism 2 including a positioning component 21, a sealing ring 22 disposed at the lower end of the positioning component 21, three positioning holes 23 arranged in a circular equidistant array disposed at the upper end of the sealing ring 22, a conical opening 24 disposed at the lower end of the positioning holes 23, a sealing groove 25 disposed on the outer side of the conical opening 24, three reinforcing ribs 26 arranged in a circular equidistant array disposed at the lower end of the sealing groove 25, a resonator 27 disposed at the front end of the reinforcing ribs 26, a rectifier 28 disposed at the upper end of the resonator 27, and three mounting components 11 arranged in a circular equidistant array disposed at the upper end of the pipe body 12. The mounting ring 13 is fixedly connected to the lower end of the tube body 12 at the rear end of the array, and the inner side of the mounting ring 13 is fixedly connected to the lower end of the tube body 12. The upper end of the sealing ring 22 is provided with three positioning members 21 arranged in a circular equidistant array. The lower end of the positioning members 21 is fixedly connected to the upper end of the sealing ring 22. The upper end of the sealing ring 22 is provided with three positioning holes 23. The outer side of the conical opening 24 is fixedly connected to the top end of the tube body 12. The opening of the conical opening 24 is larger on the side near the positioning member 21. The tube body 12 is provided with a sealing groove 25 on the side near the sealing ring 22. The lower end of the sealing ring 22 is fixedly connected to the upper end of the tube body 12. The inner side of the reinforcing rib 26 is fixedly connected to the outer side of the tube body 12. The rear end of the resonator 27 is fixedly connected to the front end of the tube body 12. The inner side of the resonator 27 is provided with a cavity that communicates with the tube body 12. The outer side of the rectifier 28 is fixedly connected to the side of the tube body 12 near the top end. The lower end of the rectifier 28 is provided with multiple rectifier holes.
[0020] In this embodiment, the mounting component 11 is fixedly connected to the tube body 12, the mounting ring 13 is fixedly connected to the tube body 12, the sealing ring 22 is fixedly connected to the positioning component 21, the upper end of the sealing ring 22 is provided with three positioning holes 23, the tapered opening 24 is fixedly connected to the tube body 12, the tube body 12 is fixedly connected to the sealing ring 22, the reinforcing rib 26 is fixedly connected to the tube body 12, the resonator 27 is fixedly connected to the tube body 12, the inner side of the resonator 27 is provided with a cavity that communicates with the tube body 12, and the rectifier 28 is fixedly connected to the tube body 12. The positioning element 21 and the positioning hole 23 work together to precisely fix the tube body 12, allowing the sealing ring 22 and the sealing groove 25 to achieve optimal performance. The dual effect of the sealing ring 22 and the sealing groove 25 on the tube body 12 reduces airflow loss during intake. The conical inlet 24 at the air inlet provides initial airflow rectification, preventing chaotic airflow from entering the tube body 12 and colliding with the tube wall, thus preventing noise generation. The flow rectifiers 28 at the rear end of the conical inlet 24 further divide and disperse the incoming airflow, transforming it into numerous fine, orderly streams. This reduces the intensity of turbulence entering the pipe 12 and decreases noise generation. The reinforcing ribs 26 on the outside of the pipe 12 increase the strength of the pipe 12, thereby reducing the vibration of the pipe 12 when the airflow collides with the pipe wall. This reduces the noise generated by the vibration of the pipe 12 caused by the airflow collision. The resonator 27 on the pipe 12 generates a sound wave with a phase opposite to the original noise sound wave and a similar amplitude. The two interfere with each other and cancel each other out, thereby reducing the noise generated by the pipe 12. In addition, the overall bending amplitude of the pipe 12 is small, which can prevent the airflow from generating vortices at the sharp bends of the pipe 12 and generating noise. Example
[0021] like Figure 1-4 As shown, the heat dissipation mechanism 3 includes heat dissipation fins 31. Two sets of symmetrical heat dissipation fins 31 are provided on the outside of the tube body 12. There are two heat dissipation fins in one set. The inner side of the heat dissipation fins 31 is fixedly connected to the outer side of the tube body 12.
[0022] In this embodiment, the heat dissipation fins 31 are fixedly connected to the tube body 12. The entire air intake bend is made of aluminum alloy, which has good thermal conductivity and can quickly dissipate heat. It also has a high melting point and good high temperature resistance. By setting the heat dissipation fins 31 on the outside of the tube body 12, the contact area between the tube body 12 and the air can be increased, so that the heat on the tube body 12 can be carried away by the air more quickly, thereby reducing the temperature of the tube body 12.
[0023] Working principle: like Figure 1-4As shown, the positioning element 21 and the positioning hole 23 cooperate to precisely fix the tube body 12, allowing the sealing ring 22 and the sealing groove 25 to achieve optimal effect. The dual effect of the sealing ring 22 and the sealing groove 25 on the tube body 12 reduces airflow loss when the tube body 12 draws in air. The conical inlet 24 at the air inlet provides initial airflow rectification, preventing chaotic airflow from entering the tube body 12 and colliding with the tube wall, thus preventing noise generation. The flow rectifier 28 at the rear end of the conical inlet 24 divides and disperses the incoming airflow, turning it into numerous small, regular streams, thereby reducing the intensity of turbulence entering the tube body 12 and reducing noise generation. The reinforcing ribs 26 on the outside of the tube body 12 increase its strength, thereby reducing... The vibration of the tube body 12 caused by the airflow colliding with the tube wall is reduced, thereby reducing the noise generated by the vibration of the tube body 12 caused by the airflow collision. The resonator 27 set on the tube body 12 can generate a sound wave with the opposite phase and similar amplitude to the original noise sound wave. The two interfere with each other and cancel each other out, thereby reducing the noise generated by the tube body 12. In addition, the overall bending amplitude of the tube body 12 is small, which can avoid the airflow generating eddies at the sharp bend of the tube body 12 and generating noise. The intake bend is made of aluminum alloy, which has good thermal conductivity and can quickly dissipate heat. It also has a high melting point and good high temperature resistance. The heat dissipation fins 31 set on the outside of the tube body 12 can increase the contact area between the tube body 12 and the air, so that the heat on the tube body 12 can be carried away by the air more quickly and the temperature of the tube body 12 can be reduced.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
