Abstract
The utility model provides an exhaust pipe, which is arranged between an automobile silencer and an automobile engine. A heat insulation cover sleeve is arranged outside the exhaust pipe. The exhaust pipe has the advantages that the structure is simple, the installation is convenient, and the defects of arrangement difficulty and space limitation when a heat insulation device is designed around the exhaust pipe are overcome.
Description
Technical field
The utility model relates to a kind of outlet pipe, particularly a kind of outlet pipe with heat insulating function.
Background technique
Silencing apparatus is to stop sound transmission and a kind of device of allowing air communication to cross, is the important measures of eliminating air power noise.Silencing apparatus is installed on the air-flow path of aerodynamic force equipment (like bigger equipment of relief opening noise such as blower, air compressor, boiler exhaust mouth, generator, water pumps) or in the inlet and exhaust system usually, in order to reduce noise.In the conventional engine exhaust system of vehicle, as shown in Figure 1, silencing apparatus 1 is installed on the car body and is connected with outlet pipe 3 through folder hoop 2.Because of the silencing apparatus temperature higher; When other component locations of silencing apparatus and automobile is nearer; For guard block can not damaged by the high temperature of silencing apparatus, all be near the vehicle frame the parts, to design heat-proof device usually, but because motor periphery component are numerous; Shan, space is little, and the layout of heat-proof device is difficulty very.
Therefore, how to provide a kind of compact structure, outlet pipe easy for installation to become the technical problem that those skilled in the art are badly in need of solving.
The model utility content
To the technical problem of above-mentioned proposition, the purpose of the utility model is to provide a kind of outlet pipe, and this exhaust pipe structure is simple, and it is convenient to install, and has overcome that around outlet pipe, to design the heat-proof device space limited, the shortcoming of difficult arrangement.
For achieving the above object, the utility model provides a kind of outlet pipe, is arranged between automotive muffler and the motor car engine, and it is outside that a thermal shield is sheathed on said outlet pipe.
According to the design of the utility model, said thermal shield comprises insulation part and is arranged on the assembly department at said insulation part two ends.
According to the design of the utility model, said insulation part comprises cover part and thermal-protective coating, and wherein said thermal-protective coating is arranged in the said cover spare.
According to the design of the utility model, said assembly department offers several strias on said thermal shield length direction.
According to the design of the utility model, said thermal shield also comprises clip, is sheathed on the said assembly department outside.
According to the design of the utility model, said assembly department is arranged at said thermal shield middle part.
According to the design of the utility model, said thermal shield is made up of thermoinsulation material.
According to the design of the utility model, said outlet pipe is connected with said silencing apparatus through the folder hoop.
The outlet pipe beneficial effect of the utility model is: thermal shield directly is arranged on the outlet pipe; Rather than continue to use traditional approach and be installed on the car body, design not only conserve space like this, and improved exhaust insulation efficient; And be convenient to install, the thermal shield stationarity also improves greatly.

The critical piece explanation
Embodiment
For ease of better understanding the utility model, combine accompanying drawing that the preferred embodiment of the utility model is specified as follows at present:
Please with reference to Figure of description Fig. 2 to Fig. 4.Wherein Fig. 2 is the outlet pipe schematic representation of the utility model; Fig. 3 is an exhaust insulation cover schematic representation among the utility model first embodiment; Fig. 4 is an exhaust insulation cover schematic representation among the utility model second embodiment.As shown in Figure 2, the outlet pipe 3 that the utility model provides is arranged between automotive muffler 1 and the motor car engine, and thermal shield 4 is sheathed on outlet pipe 3 outsides.Wherein, outlet pipe 3 one ends are sheathed on the air outlet of silencing apparatus 1, through folder hoop 2 outlet pipe 3 and the air outlet of silencing apparatus 1 are fixed.As shown in Figure 3, thermal shield 4 comprises insulation part 7 and is arranged on the assembly department 6 at insulation part 7 two ends.Wherein, insulation part 7 comprises cover part 71 and thermal-protective coating 72, and thermal-protective coating 72 is arranged in the cover part 71.Thermal-protective coating 72 can be made up of thermoinsulation material, and thermoinsulation material is meant and is used for material or the composite body that building enclosuring or Thermal Equipment, impedance hot-fluid transmit here, has both comprised thermal-protective material, also comprises acoustic damping materials, for example heat insulation fiber, pottery etc.In addition, assembly department 6 offers several strias 8 on thermal shield 4 length directions, whereby assembly department 6 is divided into several separate units.Preferably, each separate unit slightly tilts to the direction of outlet pipe 3, thereby produces certain effect that grips.Simultaneously, thermal shield 4 comprises that also clip 5 is sheathed on the outside of assembly department 6, is fixed in thermal shield 4 on the outlet pipe 3 further.
In another mode of execution of the exhaust insulation cover that the utility model provides, the middle part of thermal shield 4 also can be provided with assembly department 6, cooperates further fixing thermal shield 4 of clip 5.
In the foregoing description, semi-circular thermal shield only is provided, can the follow up needs of concrete condition of user change the shape of thermal shield, for example are combined as an annular thermal shield etc. through two semi-circular thermal shields, and the utility model is not limited thereto.
Above-described; Be merely the preferred embodiment of the utility model; Be not in order to limit the scope of the utility model; Be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.
