Description

Technical Field

[0001] The utility model relates to the technical field of air ducts for air conditioners, in particular to a sound-insulating steel-surface magnesium composite air duct. Background Art

[0002] Air ducts, also known as supply or return ducts, are an important component of air conditioning systems and are mainly used to transport and distribute cold and hot air inside buildings. Common duct materials include galvanized steel plates, aluminum plates, composite materials (such as steel-plastic composite pipes), etc. These materials have good corrosion resistance and thermal insulation properties. Air ducts deliver hot and cold air from the air conditioning unit to every corner of the room to regulate the indoor temperature. Air ducts play a key role in transmitting and distributing air in modern building air conditioning systems, and are essential for maintaining indoor temperature, comfort, and energy saving.

[0003] In order to improve the structural strength and sound insulation effect of the current air conditioning duct, a composite pipe structure is generally used. However, the composite structure inside the duct is relatively simple, which not only makes it difficult to ensure the sound insulation effect, but also makes the internal composite structure easy to separate after assembly, resulting in an unstable structure of the duct, thereby reducing the structural strength and sound insulation effect of the pipe body.

[0004] In summary, there is a need for a composite air duct with a stable structure and good sound insulation effect. Utility Model Content
