Description
Technical Field
[0001] The utility model relates to the technical field of automobile parts, and particularly relates to an automobile exhaust pipe with rapid heat dissipation. Background Technique
[0002] During the working process of the engine, the high-temperature and high-pressure gas generated by fuel combustion is discharged through the exhaust pipe. When these gases flow in the exhaust pipe, a large amount of heat energy will be released, resulting in a significant increase in the surface temperature of the exhaust pipe. The heat dissipation of the automobile exhaust pipe mainly occurs through the following several ways:
[0003] Thermal radiation: The high temperature on the surface of the exhaust pipe will radiate heat to the surrounding space, which is one of the main ways of heat dissipation;
[0004] Thermal convection: When the air around the exhaust pipe flows, part of the heat will be carried away, forming thermal convection. However, in a static state, the effect of thermal convection is relatively limited.
[0005] If the heat dissipation effect of the automobile exhaust pipe is not good, the following problems may occur:
[0006] Overheating of the exhaust pipe: Prolonged high temperature will cause the performance of the exhaust pipe material to decline, and even lead to problems such as deformation and cracking. In extreme cases, it may even cause a fire;
[0007] Influence on surrounding components: Rubber pipelines, plastic parts, etc. near the exhaust pipe may melt and age due to long-term heating, thus affecting the normal operation of the vehicle;
[0008] Increased fuel consumption and emissions: Poor heat dissipation of the exhaust pipe will affect the combustion efficiency of the engine, resulting in increased fuel consumption and emissions. This is because in a high-temperature environment, the engine needs more cooling water to maintain the normal working temperature, thus increasing fuel consumption. At the same time, the incomplete combustion of the mixture will increase the emissions of harmful substances;
[0009] Reduced driving experience: The high-temperature exhaust pipe may also increase the noise and vibration in the vehicle, affecting the comfort and safety of driving.
[0010] In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: The traditional heat dissipation method for the exhaust pipe is to increase fins on the outer wall of the exhaust pipe by welding or integrally forming during production. The heat of the exhaust pipe can be dissipated through the fins and dissipated with the wind in the air during vehicle driving. Although this heat dissipation method has a certain heat dissipation effect, the heat dissipation effect is not strong. If the fins are arranged longitudinally, the ground clearance of the vehicle chassis will be reduced, resulting in a decrease in passability when driving on potholed roads. If the fins are arranged horizontally, the fins in front will block the fins behind, resulting in rapid heat dissipation at the front end of the exhaust pipe, while the heat dissipation effect at the rear end will be greatly reduced. At the same time, in this connected way, when the vehicle drives on potholed roads and the fins are bumped, the fixation of the fins to the exhaust pipe will cause the exhaust pipe to deform and twist, resulting in unnecessary maintenance costs. Utility Model Content
[0011] The main purpose of the present utility model is to provide an automobile exhaust pipe with rapid heat dissipation, which can effectively solve the problems in the background technology.
[0012] To achieve the above purpose, the technical solution adopted by the present utility model is as follows:
[0013] An automobile exhaust pipe with rapid heat dissipation includes an exhaust pipe section. A U-shaped plate is arranged outside the exhaust pipe section. At both ends inside the U-shaped plate, a number of bent air guide plates are respectively fixed. At both ends of the U-shaped plate behind the bent air guide plates, inclined air guide plates are fixed. At the bottom of the U-shaped plate at the position below the exhaust pipe section, a number of air guide bottom grooves are equally spaced and drilled. On both side walls of the U-shaped plate, a number of air guide side holes are drilled. At both ends of the U-shaped plate at the position behind the inclined air guide plates, inclined plane grooves are drilled. At the positions of the inclined plane grooves, two L-shaped brackets are fixed. At the four corners of the top of the U-shaped plate and at the top of the L-shaped brackets, ear seats are fixed. Bolts are inserted into the ear seats.
[0014] Preferably, a number of bent air guide plates and inclined air guide plates at both ends of the exhaust pipe section are respectively located between them.
[0015] Preferably, the air guide bottom grooves are all inclined grooves.
[0016] Preferably, the air guide side holes are all inclined holes.
[0017] Preferably, a front air guide plate is fixed at the front end of the U-shaped plate. One end of the front air guide plate away from the U-shaped plate is an inclined plane sloping downward.
[0018] Compared with the prior art, the present utility model has the following beneficial effects:
[0019] 1. In the present application, a U-shaped plate is added to the outer wall of the exhaust pipe section, and a bent air guide plate and an inclined air guide plate are added inside the U-shaped plate. When the vehicle is formed, it can play a role in guiding the air flow, so that the air can blow towards the outer wall of the exhaust pipe section, enabling the temperature of its outer wall to quickly dissipate. The U-shaped plate is provided with a wind guide bottom groove drilled at the bottom of the exhaust pipe section and several wind guide side holes on the side wall of the U-shaped plate, which can form a guiding air flow again, increasing the contact between the air volume and the exhaust pipe section, and also enhancing the heat dissipation effect of the exhaust pipe section. Moreover, when dissipating heat, the pipe wall of the exhaust pipe section can be fully and evenly cooled, having better heat dissipation performance.
[0020] 2. The bolts on the U-shaped plate and the bolts on the L-shaped bracket can be connected to the vehicle chassis. The U-shaped plate, the bent air guide plate, and the inclined air guide plate are in a non-contact state with the exhaust pipe section. When the vehicle is driving on a potholed road surface, not only will the exhaust pipe section not be deformed due to minor bumps, but at the same time, it can form an outer protective plate, which can play a role in protecting and isolating the exhaust pipe section, having better safety protection effect.

[0026] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] Such as Figures 1-4As shown in the figure, a fast-heat-dissipating automobile exhaust pipe includes an exhaust pipe section 1. A U-shaped plate 2 is provided outside the exhaust pipe section 1. At both ends inside the U-shaped plate 2, a number of bent air guide plates 3 are respectively fixed. At both ends of the U-shaped plate 2 behind the bent air guide plates 3, inclined air guide plates 4 are fixed. At the bottom of the U-shaped plate 2 at the position below the exhaust pipe section 1, a number of air guide bottom grooves 5 are equally spaced and drilled. On both side walls of the U-shaped plate 2, a number of air guide side holes 6 are drilled. At both ends of the U-shaped plate 2 at the position behind the inclined air guide plates 4, inclined surface grooves 7 are drilled. At the positions of the inclined surface grooves 7, two L-shaped brackets 8 are fixed. At the four corners of the top of the U-shaped plate 2 and at the top of the L-shaped brackets 8, ear seats 9 are fixed. Bolts 10 are inserted into the ear seats 9.
[0028] Specifically, a number of bent air guide plates 3 and inclined air guide plates 4 at both ends of the exhaust pipe section 1 are respectively located between them.
[0029] Specifically, the air guide bottom grooves 5 are all inclined grooves, so that the air flowing at the bottom can be introduced into the U-shaped plate 2 by means of the air guide bottom grooves 5, increasing the air intake volume.
[0030] Specifically, the air guide side holes 6 are all inclined holes, so that the air flowing at the side end can be introduced into the U-shaped plate 2 through the air guide side holes 6, increasing the air intake volume.
[0031] Specifically, a front air guide plate 11 is fixed at the front end of the U-shaped plate 2. One end of the front air guide plate 11 away from the U-shaped plate 2 is an inclined surface that slopes downward. When the vehicle is moving, the air at the front end can be quickly introduced into the interior of the U-shaped plate 2 through the inclined surface of the front air guide plate 11.
[0032] Working principle:
[0033] In this application, by adding a U-shaped plate 2 on the outer wall of the exhaust pipe section 1, and adding bent air guide plates 3 and inclined air guide plates 4 inside the U-shaped plate 2, it can play a role in guiding the air when the vehicle is moving, so that the air can blow to the outer wall of the exhaust pipe section 1, enabling the temperature of its outer wall to be quickly dissipated. The air guide bottom grooves 5 drilled at the bottom of the U-shaped plate 2 where the exhaust pipe section 1 is located and the number of air guide side holes 6 on the side wall of the U-shaped plate 2 can form a guiding air flow again, increasing the contact between the air volume and the exhaust pipe section 1, and also increasing the heat dissipation effect of the exhaust pipe section 1. Moreover, when dissipating heat, the pipe wall of the exhaust pipe section 1 can be fully and evenly dissipated, having better heat dissipation performance. The bolts 10 on the U-shaped plate 2 and the bolts 10 on the L-shaped brackets 8 can be connected to the vehicle chassis, and there is a non-contact state between the U-shaped plate 2, the bent air guide plates 3, the inclined air guide plates 4 and the exhaust pipe section 1. When the vehicle is moving on a potholed road surface, not only will the exhaust pipe section 1 not be deformed due to small bumps, but at the same time, it can form an outer protective plate, which can play a role of protecting and isolating the exhaust pipe section 1, having better safety protection effect.
