Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to an air duct capable of preventing cold bridges. Background Art

[0002] The air duct is a piping system used for air delivery and distribution. According to the cross-sectional shape, the air duct can be divided into circular air duct, rectangular air duct, oblate air duct and other types. When the air duct is in use, the cold weather will cause the cold bridge phenomenon.

[0003] Some equipment on the market generally adopts a glass magnesium fireproof board installed on the outside of the composite air duct and an anti-cold bridge layer installed on the inside of the composite air duct, so that the heat dissipation is more uniform, and it effectively plays a role of fire prevention and heat insulation, greatly improving the heat insulation performance, which is conducive to its use in air duct equipment for various purposes.

[0004] However, in actual use, the above-mentioned equipment may fall and collide during the installation of the air duct, causing damage to the anti-cold bridge layer or fireproof board in the air duct, making the entire air duct unusable and requiring replacement, which is a waste of materials. In view of this, we propose an air duct that can prevent cold bridges. Utility Model Content
