Abstract
The invention relates to an automobile exhaust pipe which comprises an exhaust pipe body composed of an outer pipe and an inner pipe which are connected fixedly through a plurality of radiating plates. A cavity is formed between every two radiating plates, a filter screen is arranged in each cavity, a heat insulation layer is attached to the inner wall of the outer pipe, a filter screen is arranged in the inner pipe, and a damping device sleeves the outer surface of the tail portion of the exhaust pipe. The automobile exhaust pipe has the advantages of being quick in radiating, good in damping and muffling effect and the like.
Description
Technical field
The present invention relates to metal construction technical field, be specifically related to a kind of automobile exhaust pipe.
Background technique
Along with the development of China's economy, Motor Vehicle become very universal: huge numbers of families come into by automobile, industrial and agriculturally Motor Vehicle also answer land used widely.The power engine of current most of automobile is internal-combustion engine, a large amount of high-temperature tail gas can be discharged during internal combustion engine, but the weak effect that motor vehicle exhaust is heat insulation or not heat insulation, cause the temperature of outlet pipe too high, ignite oil pipe or fuel tank leakage of oil can be caused, cause Motor Vehicle burning.In addition, the effect of heat insulation of outlet pipe is poor, and using to client makes troubles, and also produces huge noise, affects daily life, be not suitable for popularization and make in automobilism.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of quick heat radiating, the automobile exhaust pipe of damping and silencing.
Realize technological scheme of the present invention as follows:
Automobile exhaust pipe, comprise the outlet pipe body by outer tube and interior pipe, described outer tube is fixedly connected with by multiple Heat sink with interior pipe, a cavity is formed between every two Heat sinks, filter screen is provided with in each cavity, with thermal-protective coating on outer tube wall, be provided with filter screen in interior pipe, described outlet pipe trailing exterior surface is arranged with damping device.
Described Heat sink is aluminium flake, and quantity is set to 6-10 block, and advantage is heat radiator successful.
Described damping device has the axle collar and spring to form, and between the axle collar, be evenly equipped with multiple spring, advantage is that spring has good cushioning effect, can reduce vibrations, reduces noise.
Described spring number is set to 4-8 root.
The material of described thermal-protective coating is high temperature high voltage resistant resin, and advantage is high temperature resistant, good heat-insulation effect.
Have employed such scheme, vehicle exhaust enters in outer tube and interior pipe respectively after entering outlet pipe, because tail gas is disperseed, cooled by Heat sink in the cavity of outer tube, cooled by interior pipe in interior pipe, tail gas heat quantity sharply leaves, cooled tail gas passes through filter screen again, filter out impurity, preventing pollution environment, heat-proof device on outer tube wall can prevent high-temperature tail gas from damaging outlet pipe, increase the service life, the damping device of outlet pipe afterbody is connected and fixed by support and automobile chassis in addition, this damping device can reduce vibrations when tail gas discharges, abate the noise.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the axonometric drawing of the A-A of Fig. 1;
Fig. 3 is the structural representation of damping device of the present invention;
In figure, 1 is outer tube, and 2 is interior pipe, and 3 is Heat sink, and 4 is filter screen, and 5 is damping device, and 6 is thermal-protective coating, and 7 is spring, and 8 is the axle collar.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As Fig. 1 to Fig. 3, automobile exhaust pipe, comprise the outlet pipe body by outer tube 1 and interior pipe 2, described outer tube 1 is fixedly connected with by multiple Heat sink 3 with interior pipe 2, form a cavity between every two Heat sinks 3, in each cavity, be provided with filter screen 4, with thermal-protective coating 6 on outer tube 1 inwall, be provided with filter screen 4 in interior pipe 2, described outlet pipe trailing exterior surface is arranged with damping device 5.
Described Heat sink 3 is aluminium flake, and quantity is set to 6-10 block, is preferably eight pieces, advantage is heat radiator successful, and damping device 5 has the axle collar 8 and spring 7 to form, and is evenly equipped with multiple spring 7 between the axle collar 8, advantage is that spring 7 has good cushioning effect, can reduce vibrations, reduce noise, spring 7 number is set to 4-8 root, be preferably the six roots of sensation, the material of described thermal-protective coating is high temperature high voltage resistant resin, and advantage is high temperature resistant, good heat-insulation effect.
