Abstract
The utility model relates to an automobile exhaust device, in particular to an automobile exhaust pipe. The automobile exhaust pipe comprises two semicircular metal arc pipes; two ends of the two metal arc pipes are connected together through connecting ferrules arranged at the ends and form a circular metal pipe, and a connected end is formed at one end of the metal pipe; and a heat insulation inner pipe with a spiral groove is transversely arranged in the metal pipe. The automobile exhaust pipe has simple structure, is convenient for assembly and disassembly, low in temperature in the exhaust process and long in service life, does not damage other external objects, and has good de-noising effect.
Description
Technical field
The utility model relates to exhaust system, relates in particular to the outlet pipe of automobile.
Background technique
Automobile exhaust pipe is one of vitals in the automobile exhaust system; Existing automobile exhaust pipe has only an exhaust to be responsible for usually; Because the gas that automobile is discharged has very high temperature; Thereby the temperature that causes exhaust to be responsible in exhaust process is higher, and the damage of shortening the working life of self easily or externally causing his thing is responsible in the higher exhaust of temperature, and exhaust simultaneously is responsible for does not have decrease of noise functions.
Summary of the invention
To above-mentioned technical problem, the utility model provides a kind of automobile exhaust pipe that can dispel the heat, have denoising structure and long service life.
The technological scheme that realizes the utility model is following:
A kind of automobile exhaust pipe; It comprises two semicircular metal arc tubes; The two ends of two metal arc tubes link together through the connection lasso that is arranged on its end; And form the metal tube of a circle and form connecting end at an end of metal tube, be horizontally arranged with in the said metal tube have spiral fluted heat insulation in pipe.
The spiral chute of heat insulation inner tube wall can be in exhaust process, makes pipe passes through in heat insulation gas form spiral duct and with its discharge, rather than direct-exhausting type, thereby can reduce the noise in the exhaust process.
Be provided with heat conductive tube between the inwall of the outer wall of pipe and metal tube in said, the inwall of said heat conductive tube is close to outer wall of inner tube, and heat conductive tube can distribute the heat on the pipe in heat insulation.
All offer a plurality of radiation holes on said two semicircular metal arc tubes, its metal arc tube is a steel pipe, and the temperature that gives out from heat conductive tube is dispersed into the outlet pipe outside through radiation hole.
Said heat insulation interior pipe adopts high temperature high voltage resistant resin, glass alkali-free cloth material to be made.
Simple in structure, the easy installation and removal of the utility model, its temperature can be too not high in the exhaust process, and its long service life can not cause damage to outside his thing yet, and excellent noise reduction effect.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1 for connecting lasso, and 2 is metal tube, and 3 is spiral chute, and 4 is heat insulation interior pipe, and 5 is heat conductive tube, and 6 is connecting end, and 7 is radiation hole.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Referring to Fig. 1; A kind of automobile exhaust pipe; Comprise two semicircular metal arc tubes; The two ends of two metal arc tubes link together through the connection lasso 1 that is arranged on its end, and form the metal tube 2 of a circle and form connecting end 6 at an end of metal tube 2, are horizontally arranged with in the metal tube to have pipe 4 in spiral chute 3 heat insulation.Be provided with heat conductive tube 5 between the outer wall of interior pipe 4 and the inwall of metal tube, heat conductive tube 5 is an aluminium matter heat conductive tube, and the inwall of heat conductive tube is close to outer wall of inner tube.All offer a plurality of radiation holes 7 on two semicircular metal arc tubes, its two metal arc tubes are steel pipe.Pipe 4 adopts high temperature high voltage resistant resin, glass alkali-free cloth material to be made in heat insulation.
