Abstract
A kind of composite air duct of the present invention relates to airduct field, it is to be made up of outer tube wall, heat-insulation layer and inner tubal wall, its inner tubal wall is placed in outer tube wall, and between periphery and the inner circumferential of outer tube wall of inner tubal wall, uniform the space between support link, inner tubal wall and outer tube wall is filled with heat-insulation layer.A kind of composite air duct of the present invention, simple in construction, easy to make, stability is high, and the problem that customer service traditional structure cannot be cleared up after inside increases support bar, good seal performance, durable, fire protecting performance is good, and maintenance cycle is long.
Description
Technical field
The present invention relates to airduct field, particularly relate to a kind of composite air duct.
Background technology
Airduct by substantial amounts of use in fields such as clean room, market, light body assembly room, wall thermal insulating, fire prevention sandwich doors, such as these Architectural Equipments are equipped with wind pipe of central air-conditioning, cold and hot conveyance conduit etc., the material of airduct tube wall is mainly by upper and lower two-layer color steel and be positioned at the heat-insulation layer in the middle of color steel and form, and airduct outer wall and four faces of inwall are all split type, airduct is to cut out the V-groove of 45 degree in this composite plate to be then converted into square when making.Coating fluid sealant or welded seal at knuckle, therefore overall simply outer wall is one, inwall is split, when airduct is oversize, can produce and rock built on the sand, tilt, steadiness extreme difference, tradition is that sealing is not only had an impact by this mode by increasing support bar at interior hollow space, and processes installation complexity, particularly to internal cleaning, generally clearing up with small machine people, middle support bar can block, it is impossible to realizes cleaning.
Summary of the invention
This practicality is for problem present in background technology, and a kind of composite air duct provided.
A kind of composite air duct of the present invention, is to be made up of outer tube wall, heat-insulation layer and inner tubal wall, and its inner tubal wall is placed in outer tube wall, and between periphery and the inner circumferential of outer tube wall of inner tubal wall, uniform the space between support link, inner tubal wall and outer tube wall is filled with heat-insulation layer.
Preferred as the present invention, the periphery, two ends of described outer tube wall is provided with chimb, uniform screw on chimb.
Preferred as the present invention, described outer tube wall and the both ends of inner tubal wall are equipped with sealing strip.
A kind of composite air duct of the present invention, simple in construction, easy to make, stability is high, and the problem that customer service traditional structure cannot be cleared up after inside increases support bar, good seal performance, durable, fire protecting performance is good, and maintenance cycle is long.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the schematic cross-section of the present invention.
Detailed description of the invention
A kind of composite air duct of 1 couple of present invention, elaborates below in conjunction with the accompanying drawings.
A kind of composite air duct of the present invention, it is to be made up of outer tube wall 1, heat-insulation layer 2 and inner tubal wall 3, its inner tubal wall 3 is placed in outer tube wall 1, and between periphery and the inner circumferential of outer tube wall 1 of inner tubal wall 3, uniform the space between support link 4, inner tubal wall 3 and outer tube wall 1 is filled with heat-insulation layer 2.The periphery, two ends of described outer tube wall 1 is provided with chimb 5, uniform screw 6 on chimb 5.Described outer tube wall 1 and the both ends of inner tubal wall 3 are equipped with sealing strip 7.
Airduct is made all-in-one-piece, first inwall can be converted into square-tube-shaped in actual manufacture, owing to insulation material is fragility, being attached to respectively by insulation material outside four inwalls, between the insulation material at four sides, attachment structure can be the modes such as phase contract, is then coated with metal outer wall outside heat-insulation layer more again, it is coated with glue between heat-insulation layer and inner tubal wall and outer tube wall, metallic walls is to be converted into square-tube-shaped, seam crossing rivet interlacement by one block of sheet material, and this all-in-one-piece airduct intensity is all improved with sealing.
As known by the technical knowledge, the present invention can be realized by the embodiment of other essence without departing from its spirit or essential feature.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only.All changes within the scope of the present invention or within being equal to the scope of the present invention are all included in the invention.
