The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
With reference to Fig. 1, Fig. 2 and Fig. 3, the structural representation of the air duct that Fig. 1 provides for first embodiment of the invention; The sectional view of the air duct that Fig. 2 provides for first embodiment of the invention; Fig. 3 is the partial enlarged drawing at A place among Fig. 2.
In the first embodiment of the present invention, air duct comprises cylindrical shell 1 and is installed on the end circle 2 at cylindrical shell 1 two ends that cylindrical shell 1 comprises from inside to outside inner barrel 11, insulation layer 12 and the outer cylinder body 13 of ring-type.
Particularly, inner barrel 11 and outer cylinder body 13 are Polyester Fibers, adopt pipe-type woven technique to make, so that cylindrical shell 1 is the positive pressure wind pipe of jointless structure, polyester fiber intensity is high, and then guarantee that the air leak rate of air curtain of cylindrical shell 1 is very low.
The air duct that present embodiment provides, end circle 2 by cylindrical shell 1 two ends connects together a plurality of air ducts, be convenient in passage, supply distinguished and admirable, and cylindrical shell 1 has insulation layer 12, can keep cylindrical shell 1 interior temperature not to be subjected to the impact of ambient temperature, keep the airflow temperature in the cylindrical shell 1 not change, guarantee distinguished and admirable refrigeration or heating effect.
On the basis of the air duct that above-described embodiment provides, can also do following improvement to it:
As shown in Figure 3, cylindrical shell 1 also comprises radioresistance layer 14, and radioresistance layer 14 is coated on the external surface of insulation layer 12, and radioresistance layer 14 can further improve the capability of resistance to radiation of cylindrical shell 1, guarantee the distinguished and admirable temperature constant in the cylindrical shell 1, guarantee distinguished and admirable refrigeration or heating effect in the cylindrical shell 1.
Need to prove, radioresistance layer 14 can be attached at inner surface and the external surface of insulation layer 12 simultaneously, also can only be attached at inner surface or the external surface of insulation layer 12, can be according to actual requirement, determine position, thickness and the material of radioresistance layer 14, with practical requirement.
As shown in Figure 1, what air duct also comprised rectangular strip hangs limit 4, and it is one-body molded with outer cylinder body 13 to hang limit 4, hangs to have several suspension ring on the limit 4 and buckle 5, is convenient to the lifting of air duct.
And the two ends of cylindrical shell 1 have anti-limit 3, and this anti-limit 3 is structure as a whole with outer cylinder body 13, and anti-limit 3 forms for the two ends reverse reflex of outer cylinder body 13 and the external surface that is attached to outer cylinder body 13, and anti-limit 3 will hold circle 2 to be wrapped in the position at outer cylinder body 13 close two ends.Such as the practicality that connects together of a plurality of air ducts, anti-limit 3 can prevent that the interface of air duct from leaking out.
