Abstract
The utility model relates to a composite thermal insulation air pipe for an air conditioner, relating to a pipeline element in heat transfer equipment, particularly a pipeline element in a central air-conditioning system. The air pipe is mainly composed of an outer shell, an inner shell, reinforcement ribs, insulation materials, a sealing element, and a connecting element. The utility model overcomes the defects of easy corrosion, poor heat-insulating property, ugly appearance and requirement of site operation of an air pipe made of galvanized steel sheets. The utility model which is suitable for various occasions has the advantages of light weight, corrosion resistance, long service life, low cost, beautiful appearance, convenient installation, etc.
Description
The utility model relates to the pipeline parts in the heat-transfer equipment, particularly relates to the pipeline parts in the central air-conditioning system.
At present, air conditioner ventilation pipeline for building adopts the galvanized steel plain sheet moulding mostly, is coated with after thermal insulating material in the wrapping, outermost surface twine with glass fiber cloth and dyes.Perhaps fit the outermost surface ornament material with macromolecular material at zinc steel plate skin.Now, domestic also useful glass fibre reinforced plastic blast pipe, honeycomb is made in the centre.These two kinds of airducts all need bigger construction site, carry out site operation, when taking a lot of work.In addition, this airduct of galvanized steel plain sheet, sheet metal is perishable, and weight is heavier, the cost height, the life-span is short, and outward appearance is not attractive in appearance.In addition, for using the heat insulation airduct of honeycomb thermal insulating material, thermal insulation property is poor.
The utility model is at some shortcomings that above-mentioned airduct still exists, designed a kind of inexpensive, but the airduct of good heat insulating.
The utility model mainly is provided with shell (1), inner casing (2), stiffening rib (3), loose fill type insulant (4), macromolecule foaming thermal insulating material (5), Sealing (6), link (7).Wherein shell (1), inner casing (2), stiffening rib (3), loose fill type insulant (4), macromolecule foaming thermal insulating material (5) constitute, and the airduct body is connected by Sealing (6) and link (7) between the body.
The utility model is compared (1) with normally used galvanized steel plain sheet airduct.In light weight, light by 20%, corrosion-resistant, the life-span can reach 20 years, (2).Excellent thermal insulation performance, the wind pipe wall thermal conductivity is 0.03～0.035kcal/mhr ℃, (3). construction is convenient by dress, can directly be transported to the job site assembling, (4). aesthetic in appearance, can make shades of colour, also can be made into different shape, (5). cost is lower by 15～20% than general airduct, (6). the dry sound of friction.The utility model is applicable to that civil building, office building central air conditioning with cold and hot airduct road, also can be used for the cold and hot supply air duct of manufacturing shop, or the ventilation duct of cleaning shop.
Fig. 1 is an integrated type airduct pipe structure schematic representation.
Fig. 2 is an airduct body plane connection diagram.
Fig. 3 is an airduct body seam connection diagram.
Fig. 4 is a plate-type airduct pipe structure schematic representation.
Embodiment of the present utility model is as follows: the airduct body can be integrated type, also can be plate-type and assembles.Be provided with the stiffening rib (3) that is used to strengthen the airduct rigidity between shell of body (1) and the inner casing (2), and loose fill type insulant (4), macromolecule foaming thermal insulating material (5), and macromolecule foaming thermal insulating material (5) is arranged on the outer end of loose fill type insulant (4), i.e. the body cross-section.Wherein the body for the plate-type airduct can be connected into integral tube with every block of plate with plastic-blasting thin plate angle bar (8) and tubular-shank rivet (9).Connect for body, when the plane connected, link (7) was a flange plate, and when seam connected, link (7) connect button for the standard tower.In addition, body shell (1) and inner casing (2) can be used various composite materials, as glass fibre reinforced plastics etc.The utility model can be made interfaces such as straight tube, bend pipe and threeway, reducing tee, four-way.
Claims (4)
1, idle call hvac duct is characterized in that constituting the airduct body by shell (1), inner casing (2), stiffening rib (3), loose fill type insulant (4), macromolecule foaming thermal insulating material (5), is connected by Sealing (6) and link (7) between the body.
2, airduct according to claim 1, it is characterized in that the airduct body can be integrated type, also can be plate-type, be provided with the stiffening rib (3) that is used to strengthen the airduct rigidity between shell of body (1) and the inner casing (2), and loose fill type insulant (4), macromolecule foaming thermal insulating material (5), and macromolecule foaming thermal insulating material (5) is arranged on the outer end of loose fill type insulant (4), i.e. the body cross-section.
3, airduct according to claim 1 and 2 is characterized in that the body of plate-type airduct can be connected into integral tube with every block of plate with plastic-blasting thin plate angle bar (8) and tubular-shank rivet (9).
4, airduct according to claim 1 is characterized in that the link (7) of airduct body can be flange plate or standard lap buckle.
