Embodiment Construction

[0011] As shown in the figure, a new type of ventilation duct includes a substrate tube 1, a wrapping layer 5 is left on the outer wall of the substrate tube 1, and a fusible material 6 is arranged in the wrapping layer 5. The inner surface of the substrate tube 1 In order to composite the heat reflection layer 2, an activated carbon layer 3 is added to the inner surface of the heat reflection layer 2, and a silencer hole 4 is provided on the substrate tube 1.

[0012] The wrapping layer 5 is made of high temperature resistant cement material.

[0013] The muffler hole 4 may be square, tapered, or the like.

[0014] The heat reflection layer 2 can cut off the contact between the wind flow and the substrate tube, avoiding the pollution of glass fiber. The heat reflection layer 2 reflects the heat rays, has good heat preservation performance, and greatly reduces the resistance of the wind flow. The substrate tube 1, Choose the material according to different uses.

[0015] After adopti...

Abstract

The invention relates to a novel air conduit. The novel air conduit comprises a base material pipe; a wrapping layer is reserved on the outer wall of the base material pipe; a fusible material is installed in the wrapping layer; the inner surface of the base material pipe is a composite heat reflecting layer, and the inner surface of the heat reflecting layer is additionally provided with an activated carbon layer; and the base material pipe is provided with a noise reducing hole. After the structure is used, the novel air conduit is green and environment friendly, and capable of purifying the impurities in the air, and eliminating the noise, and has the strong seismic stability; and in the high temperature, the fusible material in the wrapping layer is fused by absorbing the heat, so the air conduit is expanded by heating, and a cavity is formed in the wrapping layer, the heat-resisting effect is enhanced.

Description

Technical field [0001] The invention relates to a new type of ventilation duct. Background technique [0002] Existing ventilation ducts play an indispensable role in the construction industry. It can be said that without ventilation ducts, many problems in the building cannot be solved, such as gas circulation and gas exchange. However, in the field of technical level, the current ventilation ducts are not up to the standard, and their functions are relatively simple. Most of the ventilation ducts usually use organic or inorganic glass fiber reinforced plastic and gypsum base. Although these traditional materials can have good strength, The thermal conductivity is low, and the adaptability to changes in cold and heat is poor. In use, the glass fiber is easily blown out by the hot and cold wind, polluting the environment and harming the human body. These problems cannot be solved well. Summary of the invention [0003] The purpose of the present invention is to provide a new type...
