Embodiment Construction

[0023] as attached figure 1 Shown is the structural schematic diagram of the cross-section of the composite air duct. Among them, 1 is the outer layer of the air duct, 2 is the insulation layer, 3 is the surface layer of the inner wall of the air duct, 4 is the hard pipe material, and 5 is the seam strip.

[0024] The manufacturing steps of the composite air duct include: calculating the position of the required corner according to the size of the air duct, pre-embedding the pipe material 4 between the outer layer 1 and the inner wall surface layer 3; bonding the prefabricated thermal insulation material between the outer layer 1 and the inner wall surface layer 3, Become the insulation layer 2 of the composite air duct; press and bond to make the air duct composite sheet containing the hard pipe (4); when the air duct is processed, the composite sheet is bent into 90 degrees around the pipe 4 toward the direction of the inner wall surface 3; Corresponding seam strips 5 are c...

Abstract

The invention relates to a compound air duct and method thereof, wherein the shell of the compound air duct is composed of an outer surface layer 1, an insulating layer 2, an inner wall surface layer 3, a hard tube 4, a seaming strip 5 and the like, the outer surface layer 1 can be made by a colour steel plate, and the hard tube 4 is arranged between the outer surface layer 1 and the inner wall surface layer 3. The compound air duct has the advantages of light weight, corrosion resistance, long service life, good tightness and being energy saving and environmental friendly and being arranged outside, and especially has the advantages of low manufacturing cost, high strength, beautiful appearance, convenient field construction and the like, and can be applicable to major, medium and minor central air-conditioning engineering, air ventilation and exhaust and smoke ejection prevention engineering.

Description

technical field [0001] The invention relates to a composite air duct and a method thereof, in particular to a method for making and installing the composite air duct. Background technique [0002] The air duct is a gas circulation duct for air conditioning, ventilation and smoke prevention systems. The traditional galvanized sheet air duct has the disadvantages of easy corrosion, secondary insulation construction, easy damage of the insulation layer, poor insulation performance, unsightly appearance, low life, and difficulty in on-site processing; aluminum foil + insulation layer composite air duct has the disadvantages of Low strength, easy delamination, easy damage, etc.; glass magnesium board + insulation layer composite air duct has disadvantages such as bulkiness, dust drop, and moisture resistance. The airtight performance of the above-mentioned air ducts is not ideal, and they cannot be installed outdoors. Or the effect is not ideal when installed outdoors. [0003]...
