The technical issues of the utility model is solved is realized using following technical scheme：A kind of automobile exhaust pipe, including
Outer tube, inner tube, heat sink, thermal insulation layer, filter screen, damping spring, terminal pad A, terminal pad B, gas outlet, said inner tube are positioned over
In the outer tube, the heat sink is distributed in around said inner tube, and the thermal insulation layer is set to the outer tube wall, with the heat dissipation
Plate is connected, and the filter screen is positioned on the inside of said inner tube, and the damping spring is welded in the outer tube by the terminal pad A
Outer surface, the terminal pad B connections damping spring, the terminal pad B connections automobile chassis.
In the utility model, the outer tube and said inner tube are circular steel.
In the utility model, the cross-section structure of the outer tube is inclined design wide at the top and narrow at the bottom, the section knot of said inner tube
Structure is up-narrow and down-wide inclined design.
In the utility model, the heat sink is aluminium block, and quantity is set as 6-10 blocks, between the heat sink described in each two
Form cavity.
In the utility model, the insulating layer material is high temperature high voltage resistant resin.
In the utility model, the filter screen is installed on said inner tube close to one end of the gas outlet.
In the utility model, the damping spring is connect by welding with the terminal pad A and the terminal pad B.
The beneficial effects of the utility model：Inner tube is designed to that up-narrow and down-wide ramp structure, outer tube are set by the utility model
Ramp structure wide at the top and narrow at the bottom is counted into, the outflow of cooling water is conducive to, extends the service life of exhaust pipe.In automobile exhaust pipe
Addition heat sink and thermal insulation layer between pipe and outer tube so that the high temperature in internal combustion engine can dissipate in a short time, will not will be hot
Amount is transmitted to the oil pipe or fuel tank of motor vehicle, causes danger, antirattle spring is installed on automobile exhaust pipe, can prevent exhaust pipe
It is damaged because of external force, fixed exhaust pipe can also be played the role of.

Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Embodiment：As depicted in figs. 1 and 2, a kind of automobile exhaust pipe, including outer tube 1, inner tube 2, heat sink 3, thermal insulation layer 4,
Filter screen 5, damping spring 6, terminal pad A7, terminal pad B8, gas outlet 9, said inner tube 2 are positioned in the outer tube 1, described to dissipate
Hot plate 3 is distributed in around said inner tube 2, and the thermal insulation layer 4 is set to 1 inner wall of the outer tube, is connected with the heat sink 3, described
Filter screen 5 is positioned over 2 inside of said inner tube, and the damping spring 6 is welded in 1 appearance of the outer tube by the terminal pad A7
Face, the terminal pad B8 connections damping spring 6, the terminal pad B8 connections automobile chassis.The outer tube 1 and said inner tube
2 be circular steel.The cross-section structure of the outer tube 1 is inclined design wide at the top and narrow at the bottom, and the cross-section structure of said inner tube 2 is upper narrow
Lower wide inclined design.The heat sink 3 is aluminium block, and quantity is set as 6-10 blocks, is formed between the heat sink 3 described in each two
