For the those of ordinary skill in field, concrete meaning of the above-mentioned term in the utility model can be understood with concrete condition.
It should be noted that while cold-proof structure has cold-proof effect, it is inevitable that also there is heat-insulated effect.The present embodiment
Although only define " cold-proof " characteristic of structure, but it is to be understood that structure has cold-proof effect effect of heat insulation, depends on
Depending on the application environment of structure.
Fig. 1, the cold-proof structure of the present embodiment, including multilayer insulating layer are referred to, each layer insulating layer is prevented by polylith
Cold board material splice forms, and the splicing sheet material on the adjacent insulating layer is staggered, to cause on the adjacent insulating layer
Splicing seams mutually stagger.
The cold-proof structure uses the structure of multilayer insulating layer overlapping, while being easily installed, can facilitate to insulating layer
Processing is compressed, so as to rationally reduce the thermal conductivity factor of insulating layer.Also, because every layer of insulating layer is by the cold-proof sheet material of polylith
It is spliced, and the splicing sheet material on the adjacent insulating layer is staggered, so as to be further ensured that cold-proof structure
Cold-proof effect.
Wherein, the material of insulating layer is in most cases using porous media material, and the sky of porous media material
Gap rate is different, and the cold-proof effect of corresponding insulating layer is also different.Thus, when the present embodiment uses the insulating layer of porous media material,
By carrying out different degrees of compression to insulating layer, the voidage of insulating layer can be controlled.When insulating layer reaches optimal
During voidage, insulating layer will also obtain optimal cold-proof effect.
On this basis, each layer insulating layer of the present embodiment can be obtained by division process.It is further cold-proof to each layer
Layer carries out the pure physical methods such as overlapping, compression, and then causes cold-proof structure to obtain optimal cold-proof effect.
In the present embodiment, in order to ensure the cold-proof effect of cold-proof structure, the material of the insulating layer used is Carbon fiber thermal insulation
Cotton.Due to Carbon fiber thermal insulation cotton be realized by the air in carbon fiber space it is cold-proof, therefore voidage will directly affect it is anti-
The cold-proof effect of cold layer.
In order to further improve the cold-proof effect of each layer insulating layer, the side wall of preferably cold-proof sheet material is in non-planar, such as
Curved, stepped or zigzag etc..
Also, for the ease of the splicing of adjacent cold-proof sheet material on a certain insulating layer, it can also be set in the side wall of cold-proof sheet material
It is equipped with splicing projection and/or splicing groove.So as to the spelling on the raised embedded adjacent cold-proof sheet material of the splicing of a certain cold-proof sheet material
When connecing groove, the adjacent cold-proof sheet material mortise-tenon joint that splices mutually.
In Fig. 1, the quantity of insulating layer is four layers, respectively the first insulating layer 1, the second insulating layer 2, the and of the 3rd insulating layer 3
4th insulating layer 4.
It is preferred that but necessarily the thickness of the first insulating layer 1 is 10mm, the thickness of second insulating layer 2 is 20mm, institute
The thickness for stating the 3rd insulating layer 3 is 30mm, and the thickness of the 4th insulating layer 4 is 50mm.By a large amount of it was verified that this kind of feelings
Under condition, cold-proof structure can obtain preferable cold-proof effect.
Certainly it should be noted that the quantity of the insulating layer in Fig. 1 does not form the limitation to the present embodiment.It is for example, cold-proof
Layer can also be selected as three layers, five layers, six layers etc..
On the basis of the above, the present embodiment also provides a kind of rail vehicle, including above-mentioned cold-proof structure, and by cold-proof structure
Between car body inner surface and trim panel.
Due to often having some protrusions with respect to envelope protrusion in car body on car body surface, therefore for the ease of cold-proof
Structure is installed, and the avoid holes of protrusion can be set on the insulating layer close to the car body inner surface.
When cold-proof structure includes above-mentioned first insulating layer 1, the second insulating layer 2, the 3rd insulating layer 3 and four insulating layers 4,
First insulating layer 1 is close to car body inner surface setting, and the first insulating layer 1, the second insulating layer 2, the 3rd insulating layer 3 and the 4th are anti-
Cold layer 4 is set gradually along the car body to the trim panel direction.In the case of this kind, avoid holes are arranged on the first insulating layer 1
On, after the first insulating layer 1 installs, upper second insulating layer 2, the 3rd insulating layer 3 and the 4th insulating layer 4 are covered successively, so as to
The exposed of protrusion can be avoided, improves the cold protective performance of car body.It is also, abundant by car body installed part when cold-proof structure is installed
Extrude cold-proof structure so that cold-proof structure obtains optimum compression ratio.
It should be noted that the cold-proof structure of the present embodiment, in addition to suitable for rail vehicle, can be applicable to other
Need to set the occasion of cold-proof structure.
Embodiment of above is merely to illustrate the utility model, rather than to limitation of the present utility model.Although with reference to implementation
The utility model is described in detail example, it will be understood by those within the art that, to technology of the present utility model
Scheme carries out various combinations, modification or equivalent substitution, all should without departure from the spirit and scope of technical solutions of the utility model
Cover among right of the present utility model.
