Abstract

The invention discloses a heat-insulated spiral duct which comprises an inner duct and an outer duct. The inner duct and the outer duct are correspondingly arranged in a sleeve-joint manner. The inner duct and the outer duct are bent pipes. The outer duct sleeves the outer side of the inner duct. The pipe surfaces on the inner side and the outer side of the inner duct are smooth surfaces. The pipe surfaces on the inner side and the outer side of the outer duct are unsmooth surfaces. A plurality of tapered bumps are arranged on the pipe surface of the outer side of the outer duct in a protruding manner. A part between the inner duct and the outer duct is filled with a rubber elastic membrane. Through adoption of the way, the strength of the heat-insulated spiral duct can be improved, and the inner duct and the outer duct, which are arranged in a sleeve-joint manner, are arranged in the heat-insulated spiral duct, so that the heat-insulated spiral duct is thicker and more durable, the hardness of the heat-insulated spiral duct can be improved, and compression damage of the heat-insulated spiral duct, which is caused when the heat-insulated spiral duct is impacted with external force, is avoided.

Description

Technical field [0001] The invention relates to the field of spiral air ducts, in particular to an adiabatic spiral air duct. Background technique [0002] The adiabatic spiral duct is a new type of mechanical ventilation duct, which has the characteristics of low resistance, good strength, beautiful appearance and convenient installation. It is widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airports, tunnels and other construction industries. However, the traditional insulated spiral duct has a simple structure and cannot cope with greater pressure. It is prone to deformation and damage when subjected to external pressure impact, which reduces the service life of the insulated spiral duct. Summary of the invention [0003] The main technical problem solved by the present invention is to provide an insulated spiral air duct, which can improve the strength of the insulated spiral air duct. The insulated spiral air duct is provided wi...
