Abstract
The utility model relates to an exhaust system thermal insulation shield applied to a pressurizer engine. The exhaust system thermal insulation shield applied to the pressurizer engine comprises a thermal insulation shield body. The whole thermal insulation shield body is of a there-layer structure. The inner and outer layers are respectively an aluminizing steel plate outer layer and an aluminizing steel plate inner layer. An interlayer is arranged between the aluminizing steel plate outer layer and the aluminizing steel plate inner layer. The interlayer is a ceramic fiber paper layer. The exhaust system thermal insulation shield applied to the pressurizer engine is simple in structure, and reasonable in design. Heat emitted by an exhaust pipe can be fine insulated, and thus damage to other devices is avoided. Noise, vibration and harshness (NVH) properties of a whole car is not affected. Performance of thermal insulation shield is improved, and quality is enhanced.
Description
Technical field
The utility model relates to a kind of auto parts and components, and particularly a kind of engine exhaust system thermal shield is heat insulation for the noise reduction of pressurized machine vehicle engine exhaust divided manifold.
Background technique
In automobile market of today, the vehicle of carrying supercharged engine is more and more, and supercharged engine has advantages of that than the general nature airbreathing motor power is stronger more fuel-efficient, and technology is more advanced.Raising along with the engine technology level, the heat that engine exhaust system distributes is also increasing, the thermal radiation effect of parts is on every side strengthened day by day, car load is pursued again compact day by day, so comfortable heat insulation measures is essential, the effect of thermal shield reduces the thermal radiation of engine exhaust system and develops, and improves the durable and travelling comfort of car load.Existing thermal shield adopts one deck steel plate to make usually, and effect of heat insulation is poor, the manifold radiated noise of can not decaying.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provide a kind of simple in structure, reasonable in design, can prevent effectively that the too high thermal radiation of engine exhaust system from damaging parts on every side, the vent systems thermal shield that is applied to supercharged engine of heat-insulation noise-reduction successful.In order to achieve the above object, the technical solution adopted in the utility model is: comprise the thermal shield body, the whole three-decker that adopts of described thermal shield body, inside and outside two-layer aludip skin and the aludip internal layer of being respectively, be the mesosphere between aludip skin and aludip internal layer, the mesosphere is the ceramic fiber ply of paper.The utility model has the advantages that: 1, simple in structure, reasonable in design, well intercept the heat that outlet pipe comes out, avoid other device is damaged; 2, do not affect car load NVH performance; 3, improve the thermal shield performance, improved quality.
Description of drawings
Fig. 1 is the utility model thermal shield body structure schematic diagram;
Fig. 2 is the utility model partial structurtes sectional views.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.By Fig. 1-Fig. 2 as can be known, the utility model comprises thermal shield body 4, the whole three-decker that adopts of described thermal shield body, inside and outside two-layer aludip outer 1 and the aludip internal layer 3 of being respectively, be the mesosphere between aludip outer 1 and aludip internal layer 3, the mesosphere is ceramic fiber ply of paper 2.Adopt flanging, part to turn over all over structure around the described thermal shield body 4.The utility model major function is to prevent that the too high thermal radiation of engine exhaust system from causing damage to parts on every side.Adopt similar and structure sandwich, inside and outside two-layer aludip, the mesosphere is ceramic fiber paper, reasonable in design, good heat-insulation effect.The aludip of sandwich structure outside can prevent aqueous vapor, the destruction of the corrosive goods confrontation thermal shield bodies such as oil gas; Middle ceramic fiber paper can play the effect of damping noise reduction, is conducive to the NVH of car load; Adopt flanging around the thermal shield, and then locally turn over that more to be conducive to the durable and technique of thermal shield all over structure simple, also can play the protection ceramic fiber paper and burn and lose.
Claims (2)
1. vent systems thermal shield that is applied to supercharged engine, comprise thermal shield body (4), it is characterized in that: the whole three-decker that adopts of described thermal shield body, inside and outside two-layer aludip skin (1) and the aludip internal layer (3) of being respectively, be the mesosphere between aludip outer (1) and aludip internal layer (3), the mesosphere is ceramic fiber ply of paper (2).
2. a kind of vent systems thermal shield that is applied to supercharged engine according to claim 1, it is characterized in that: described thermal shield body (4) adopts flanging on every side, and turn over all over structure the part.
