Abstract
The invention relates to an exhaust pipe which comprises a turned edge, an exhaust pipe body, a heat-dissipating layer, an antioxidation layer, a tail gas filtering device and a connecting piece, wherein the outlet end of the exhaust pipe body is provided with the turned edge bent towards the interior of the exhaust pipe body; the other end of the exhaust pipe body is provided with the connecting piece; the exhaust pipe body is of an integral structure molded once; the tail gas filtering device is positioned in the exhaust pipe body and can purify tail gases; the heat-dissipating layer is positioned at the external surface of the exhaust pipe body and wraps the whole exhaust pipe body; the antioxidation layer is positioned at the outer side of the heat-dissipating layer. Therefore, the problems of low strength and slow cooling are solved.
Description
Technical field
The invention belongs to technical field of automobile parts, particularly relate to a kind of outlet pipe.
Background technique
Outlet pipe is for discharging automobile exhaust gas, in discharge process, because the exhaust gas temperature of discharge is higher and have certain impact force and be easily corroded, therefore in the design process of outlet pipe, the intensity of outlet pipe and anticorrosive degree, the especially intensity of exhaust outlet end seem particularly important.Is all now generally that method by increasing outlet pipe wall thickness improves the intensity of outlet pipe and anticorrosive degree, but along with the increase of thickness, cost of production is corresponding increase also.
Automobile is the machinery producing power by internal-combustion engine and operate, its fuel is generally the oil products such as bavin Water Oil Or Gas, oil product burning can produce a large amount of waste gas, need to be discharged by outlet pipe, waste gas is contaminated air not only, and with certain very high temperature, and the temperature of outlet pipe also cannot decline rapidly at short notice, easily cause the children that user or periphery are played, scalded because of the outlet pipe of false touch high temperature, cause the injury being difficult to make up.
Summary of the invention
The invention provides a kind of outlet pipe, low to solve intensity in above-mentioned background technology, slow problem of lowering the temperature.
Technical problem solved by the invention realizes by the following technical solutions: the invention provides a kind of outlet pipe, comprise crimping, exhaust pipe, heat dissipating layer, antioxidant layer, tail gas filter and link, the outlet end of described exhaust pipe is provided with crimping bending in body, the other end of described exhaust pipe is provided with link, described exhaust pipe is once-through integral structure, described tail gas filter is positioned at the inside of exhaust pipe, the outer surface that described heat dissipating layer is positioned at exhaust pipe wraps whole body, described antioxidant layer is positioned at the outside of heat dissipating layer.
Described exhaust pipe is hollow and double-edge open body.
Described antioxidant layer material is titanium dioxide.
Described exhaust pipe is bending shape.
beneficial effect of the present invention is:
1, the surface of body of the present invention is through Overheating Treatment, and adds fine and close antioxidant layer at surface overcoats, can reach corrosion-resistant effect, can not reduce the intensity of outlet pipe owing to using for a long time, thus reduces cost of production.
2, the surface of body of the present invention is provided with heat dissipating layer, and heat energy remaining on body can be taken away comparatively rapidly via heat dissipating layer, makes the bulk temperature of outlet pipe comparatively fast to decline and to cool, and avoids the situation of scalding to occur.
3, inside of the present invention is provided with tail gas filter, can cleaning of off-gas, makes the waste gas of discharge can reach the emission standard of national regulation.
4, body of the present invention is once-through integral structure, and is provided with crimping bending in body at outlet end, can improve the intensity of body entirety.
5, structure of the present invention is simple, and reasonable in design, the intensity of body entirety is high, and cost of production is low, is suitable for mass production.
Accompanying drawing explanation
Fig. 1 is cut-away view of the present invention.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.
In figure: 1-crimping, 2-exhaust pipe, 3-heat dissipating layer, 4-antioxidant layer, 5-tail gas filter, 6-link.
The outlet end of exhaust pipe 2 is provided with crimping 1 bending in body, the design of crimping 1 can improve the intensity of body, the other end of described exhaust pipe 2 is provided with link 6, tail gas filter 5 is positioned at the inside of exhaust pipe 2, can cleaning of off-gas, make the waste gas of discharge can reach the emission standard of national regulation, heat dissipating layer 3 is positioned at the outer surface of exhaust pipe 2, heat energy remaining on exhaust pipe 2 can be taken away comparatively rapidly via heat dissipating layer 3, the bulk temperature of outlet pipe is made comparatively fast to decline and to cool, antioxidant layer 4 is positioned at the outer surface of heat dissipating layer 3, corrosion-resistant effect can be reached, the intensity of outlet pipe can not be reduced owing to using for a long time.
Exhaust pipe 2 is once-through integral structure, can improve the intensity of body entirety.
Exhaust pipe 2 is hollow and the kink shape body of double-edge open.
Utilize technical solutions according to the invention, or those skilled in the art being under the inspiration of technical solution of the present invention, designing similar technological scheme, and reach above-mentioned technique effect, is all fall into protection scope of the present invention.
