ラルダクト。[Claims for Utility Model Registration] 1. The base 1 of the duct is made of a thin metal plate such as iron or aluminum, and one surface of the base 1 or both surfaces of the base 1 are coated with a heat-resistant material such as synthetic resin. A multilayer duct structure for preventing dew condensation, which is formed by forming a film 2 of a poor conductor to a desired thickness. 2 The base of the duct is made of a thin metal plate such as iron or aluminum, and a thin metal plate of a specified width is formed by forming a film of a thermally poor conductor on one surface or both surfaces of the base. In the spiral duct a, which forms a cylindrical body by spirally winding the edges of the multi-layered structure 1 and 1, several ducts are placed in the middle of the adjacent 1 and 1 portions. When the corrugated ribs 2...2 are formed and the corrugated ribs 2...2 are brought into close contact with each other so as to be able to expand and contract freely, when the corrugated ribs 2...2 are brought into close contact with each other, these corrugated ribs 2...2 The inner and outer tips of the ribs 2...2 are bent so that the bent tips become almost linear, and the opposing side wall surfaces of the corrugated ribs 2...2 are brought into close contact with each other to form a corrugated rib. The spiral duct according to claim 1, which is a utility model, and is formed so that virtually no space is formed in the portion thereof.
