摘要：
Provided is an integrated spiral duct (100) including: a curved duct (100); and straight connection ducts (200) formed at both ends of the curved duct (100), wherein the curved duct is integrally formed with the straight connection ducts in spiral type without any joint. Therefore, since a metal strip is continuously wound to form a duct without any joint it is possible to reduce the number of manufacturing process to remarkably increase productivity, quality, and durability.
