Description
Technical field
The present invention relates to automotive field, specifically a kind of automobile exhaust pipe with high-efficient radiating function of automobile exhaust system.
Background technique
Along with the development of China's economy, it is very universal that Motor Vehicle becomes, present each family nearly all has an automobile, people are when selecting automobile, not only focus on the appearance of automobile, the safety and stability of automobile and environmental consciousness are also extremely valued, in recent years, urban motor vehicle increases very fast, incident traffic noise pollution environmental phenomenon also becomes increasingly conspicuous, automobile is noise pollution to the harm that environmental protection is maximum, investigation shows, motor vehicle noise accounts for 85.5% of urban traffic noise, along with the development of automotive energy-saving emission-reducing, require that automobile reduces noise, energy saving consumes.And the topmost noise of automobile is from the vent systems of automobile, i.e. motor vehicle exhaust emission noise, in order to reduce motor vehicle exhaust emission noise, meet the requirement of automobile environment-protection, traditional automobile exhaust system realizes noise elimination noise reduction by fixing a silencer, but acoustic wave filter structure is complicated, and install also inconvenient.
Except noise problem, also there is the difficult problem that two needs overcome in automobile tail gas pipe, and first: in use, outlet pipe is the parts damaged that get rusty easily to the Motor Vehicle such as automobile, particularly those mainly city short distance travel automobile, outlet pipe get rusty damage phenomenon more outstanding.Study by analysis, find outlet pipe get rusty easily most damage major reason, except the material with outlet pipe generally understood is relevant, when another major reason is because of each automobile running, owing to just starting working, whole section of outlet pipe or temperature is lower, the damp and hot waste gas that motor ejects through colder outlet pipe, can in outlet pipe particularly the silencing apparatus position of outlet pipe meet cold and produce condensed water.If automobile running time long enough, then outlet pipe slowly heating under the heating of waste gas, the condensed water produced can be fallen by heating evaporation, if but automobile does short distance to travel in city, running time long just end travels and flame-out parking, then outlet pipe does not also reach enough temperature, the condensed water produced also just also is not evaporated and remains in outlet pipe particularly in silencing apparatus, and the sulfur dioxide in water and automobile exhaust gas, the gases such as nitrogen dioxide can produce acid after combining, corrode outlet pipe and make its damage that gets rusty easily, and the automobile tail gas pipe after getting rusty is not easy to clean, damage attractive in appearance, second: the noise that motor operationally produces comprises this bulk noise of motor and the exhaust sound of motor, exhaust gas temperature due to emission by exhaust pipe is higher and have certain impact force, therefore in the design process of outlet pipe, the temperature how reducing waste gas is a key factor.But current used outlet pipe, its structure comparison is single, before waste gas is discharged from outlet pipe, does not have corresponding structure that the temperature of waste gas is obtained and reduces, cause the gas temperature of discharging from outlet pipe higher, produce many adverse effects to environment.
summary of the invention.
Goal of the invention: in order to solve the deficiencies in the prior art, the invention provides a kind of structure simple, and working stability is reliable, conveniently can install and remove, not easily stockpile water in outlet pipe, can the automobile exhaust pipe of high efficiency and heat radiation.
Technological scheme: in order to realize above object, the automobile exhaust pipe of a kind of high efficiency and heat radiation of the present invention, it comprises: outlet pipe body, silencing cotton, arc shaped surface, water-leaking hole, mounting hole and noise elimination portion, one end of described outlet pipe body is conical surface body, conical surface body is provided with mounting hole, the other end of outlet pipe body is exhaust outlet, turning in the middle of outlet pipe body is noise elimination portion, arc shaped surface is provided with in outlet pipe body, the middle of adjacent two arc shaped surfaces above outlet pipe body interior is provided with silencing cotton, by adding silencing cotton in outlet pipe body interior, for adsorbing noise and eliminating, the erasure effect of device can be improved, the middle of adjacent two arc shaped surfaces below outlet pipe body interior is provided with water-leaking hole, when automobile running terminates to stop, if short distance travels, when the condensed water that outlet pipe produces also is not remained in outlet pipe by fully evaporating, condensed water will directly flow out from the water-leaking hole outlet pipe, can not be accumulated in outlet pipe, reduce the condensed water in outlet pipe and the sulfur dioxide in automobile exhaust gas, the acid attack outlet pipe produced after the gases such as nitrogen dioxide combine makes its impaired situation that gets rusty easily occur.
