Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets the utility model
Embodiment, and be used to explain the principles of the present invention together with specification.
Fig. 1 is the structural schematic diagram of the heat-proof device provided by the embodiment of the utility model for engine periphery pipeline.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
As shown in Figure 1, the heat-proof device provided by the embodiment of the utility model for engine periphery pipeline comprising every
Thermosphere 1 and covering 2, in which: the side of thermal insulation layer 1 is coated on around the pipeline of engine periphery, the other side of thermal insulation layer 1 and illiteracy
Skin 2 connects；The material of thermal insulation layer 1 is ceramic matric composite or glass fibre；Covering 2 uses density for 7.93 × 103kg/m3,
With a thickness of the stainless steel of 0.05~0.08mm, and covering 2 is arranged to the tread patterns modeling of 1.3~1.5mm thickness.
Wherein, thermal insulation layer 1 plays the role of completely cutting off heat.The material of thermal insulation layer 1 is according to relevant criterion in the utility model
It is calculated with calorifics, the thermal coefficient of 1 material of thermal insulation layer should meet condition shown in the following table 1.Ceramic matric composite or
Glass fibre is all satisfied condition shown in table 1.
Table 1
| Serial number | Temperature (DEG C) | Thermal coefficient (W/m K) |
| 1 | 400 | 0.069 |
| 2 | 650 | 0.075 |
| 3 | 900 | 0.080 |
Further, the material of covering 2 is calculated according to relevant criterion and mechanical performance in the utility model, covering 2
