Abstract
The utility model relates to an engine exhaust pipe. The technical scheme of the engine exhaust pipe lies in that the engine exhaust pipe comprises an inner pipe, wherein a heat insulation pipe is wrapped outside the inner pipe, and a vacuum cavity is arranged between the inner pipe and the heat insulation pipe. The engine exhaust pipe has the advantages that hot gas is protected by the external heat insulation pipe, so that a heat source cannot be directly contacted with other quick-wear parts so as to guarantee that parts cannot be fired; and meanwhile, potential safety hazards are eliminated, therefore, people cannot be fired during getting close to the exhaust pipe.
Description
Technical field
The utility model is a kind of engine exhaust pipe.
Background technique
Vent systems is as the output processing apparatus of engine exhaust emission, and most of automobile manufacturing enterprise is not deep especially for the development and Design of vent systems, just designs vent systems so that engine exhaust is output as purpose merely.At present, the structure of outlet pipe all is the individual layer iron sheet structure, the outlet pipe of this structure, often to the car load design arrangement time, all to consider with some can not resistant to elevated temperatures component away from outlet pipe.And often because the restriction of factors such as space, structure, when practical application, some can not resistant to elevated temperatures component still compare nearerly apart from outlet pipe, cause automobile in use for some time, and near some component the outlet pipe are damaged by calcination.
Summary of the invention
The utility model is to the deficiency of existing technology, in order to reduce distributing in a large number of outlet pipe endogenous pyrogen, prevents that the thermal source calcination can not resistant to elevated temperatures component, invented a kind of novel exhaust pipe with heat insulating tube, simple in structure, the low cost of manufacture of this technological scheme.
The utility model is realized through following technical measures: a kind of engine exhaust pipe, comprise interior pipe, and said interior pipe is wrapped with heat insulating tube, is vacuum chamber between said interior pipe and the heat insulating tube.
The concrete characteristics of the utility model also have, and the length of above-mentioned heat insulating tube is less than the length of interior pipe.
The beneficial effect of the utility model is: under the protection of enclosure heat pipe outside of the hot gas of pipe the inside, thermal source can directly not contacted with other easily damaged parts like this, guarantee that component can calcination; Eliminated potential safety hazard simultaneously, can not be deflated the pipe calcination when making the people near outlet pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Among the figure, 1, interior pipe, 2, heat insulating tube, 3, vacuum chamber.
Embodiment
For clearly demonstrating the technical characterstic of this programme, through an embodiment, this programme is set forth below.
Shown in accompanying drawing, a kind of engine exhaust pipe, pipe 1 in comprising, said interior pipe 1 is wrapped with heat insulating tube 2, is vacuum chamber 3 between said interior pipe 1 and the heat insulating tube 2.
The concrete characteristics of the utility model also have, and the length of above-mentioned heat insulating tube 2 is less than the length of interior pipe 1.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
Claims (1)
