The effective heat insulation structural of automobile exhaust

Technical field

The utility model relates to the technical field of automobile heat insulation, particularly relates to a kind of effective heat insulation structural of automobile exhaust, special Do not relate to a kind of double thermal insulation structure being applied to automobile exhaust pipe head section.

Background technology

At present, the stainless steel blast pipe using in automobile industry compared with non-refractory, easily by car near enging cabin its Remaining part melts or the danger burnt, and tends to have noise.

To this end, designer of the present utility model is in view of drawbacks described above, by concentrating on studies and designing, comprehensively for many years for a long time Being engaged in experience and the achievement of related industry, research and design goes out a kind of effective heat insulation structural of automobile exhaust, to overcome drawbacks described above.

Utility model content

The purpose of this utility model is to provide a kind of effective heat insulation structural of automobile exhaust, its simple in construction, and handling are convenient, Effect of heat insulation is good, widely applicable.

For solving the problems referred to above, the utility model discloses a kind of effective heat insulation structural of automobile exhaust, be coated on automobile row The outer peripheral edge of tracheae, it is characterised in that:

Described heat insulation structural is double-decker, and it comprises heat insulation foam layer and thermal baffle layer, and described heat insulation foam layer is asbestos system Becoming and be coated on the outer peripheral edge of automobile exhaust pipe, described thermal baffle layer is the periphery that heat insulation foam layer was made and be coated on to rigid Edge.

Wherein: described thermal baffle layer is stainless steel matrixes for embossing.

Wherein: be fixed on outside automobile exhaust pipe both sides by spot welding mode after the inward at both ends contracting of described thermal baffle layer Edge, middle formation is described to accommodate with automobile exhaust pipe matched radian moulding distance automobile exhaust pipe outer rim certain distance Heat insulation foam layer.

Wherein: the thickness of described heat insulation foam layer is set to 5-7mm, the thickness of described thermal baffle layer is set to 0.18-0.22mm.

Wherein: the thickness of described heat insulation foam layer is set to 6mm, the thickness of described thermal baffle layer is 0.2mm.

By said structure, the effective heat insulation structural of automobile exhaust of the present utility model has the effect that

1st, heat insulation structural can significantly reduce the temperature of cabin, also provides soundproof effect, and nonflammable, and space utilization rate is high, Working of plastics around also can obtain safe guarantee；

2nd, simple in construction, it is easy to manufacture, widely applicable, effectively improve service life and reduce use cost.

Detailed content of the present utility model can be obtained by explanation described later and institute's accompanying drawing.

Brief description

Fig. 1 shows the overall schematic of the effective heat insulation structural of automobile exhaust of the present utility model.

Fig. 2 shows the sectional view of a preferred embodiment in the utility model.

Reference:

10th, automobile exhaust pipe；101st, blast pipe head section；11st, heat insulation structural；111st, heat insulation foam layer；112nd, thermal baffle layer.

Detailed description of the invention

See Fig. 1 and 2, it is shown that a wherein embodiment of the effective heat insulation structural of automobile exhaust of the present utility model.

Figure 1 illustrates automobile exhaust pipe 10 and be provided with heat insulation structural 11 of the present utility model, described heat insulation structural 11 wraps Be overlying on the outer peripheral edge of automobile exhaust pipe 10, as a rule, existing a large amount of existing turbine vehicle exhaust pipe head section due to position relationship, The height that temperature all can compare, therefore, in the outer peripheral edge of the blast pipe head section 101 shown in Fig. 2, the application of heat insulation structural 11 more added with Effect.

And in order to preferably be thermally shielded and safety, described heat insulation structural 11 is double-decker, it comprises heat insulation foam layer 111 With thermal baffle layer 112, described heat insulation foam layer 111 is coated on the outer peripheral edge of automobile exhaust pipe 10, and described thermal baffle layer 112 is rigidity The outer peripheral edge of heat insulation foam layer 111 is made and be coated on to material.

Wherein, described heat insulation foam layer 111 is made for asbestos, thus, provides excellent sound insulation and reduces temperature effect, with When thermal baffle layer 112 rigidity can ensure that position and the effect of heat insulation of heat insulation foam layer 111.

Optionally, the thickness of described heat insulation foam layer 111 is set to 5-7mm, preferably 6mm, the thickness of described thermal baffle layer 112 Degree is set to 0.18-0.22mm, preferably 0.2mm, can be suitable for more extensive scope, ensure most preferably also by preferred thickness Effect of heat insulation, also improve space availability ratio.

Preferably, described thermal baffle layer 112 is stainless steel matrixes for embossing, it is further preferred that described thermal baffle layer uses 304 The stainless steel matrixes for embossing of material, is fixed on automobile exhaust pipe by spot welding mode after the inward at both ends contracting of described thermal baffle layer 112 The outer rim of 10 both sides (preferably blast pipe head section 101 two ends), middle formation and automobile exhaust pipe 10 matched radian moulding And distance automobile exhaust pipe 10 outer rim certain distance is to accommodate described heat insulation foam layer 111, this certain distance can be equal to or slightly less than Heat insulation foam layer 111 thickness (preferably smaller than 0.1-0.2mm), wherein, described thermal baffle layer can go out radian by punching press one-shot forming Moulding, to improve manufacture efficiency, reduces manufacturing cost.

Wherein, described stainless steel matrixes for embossing comprises embossed surface, and this embossed surface is saved in the case of ensureing rigidity Material, reduces weight, moreover it is possible to be beneficial to the minimizing of noise.

As can be seen here, the utility model has the advantage that

It is readily apparent that above description and record are only to illustrate rather than in order to limit disclosure of the present utility model Content, application or use.Although described and be described in the drawings embodiment in an embodiment, but the utility model Do not limit by accompanying drawing example and be described as in an embodiment it is now recognized that optimal mode to implement religion of the present utility model The specific examples led, scope of the present utility model will include any enforcement falling into description and appended claims above Example.
