Problems solved by technology
In reality, the air ducts made of these two materials have many shortcomings: the air ducts made of ordinary aluminum plates have simple structures, do not have the characteristics of sound insulation and heat insulation, and the loss of hot and cold air is very high when they are transmitted inside. Large, and the strength of simple aluminum plate products is not high and easy to deform
FRP products are prone to aging and cracking, and cannot be recycled and reused

Embodiment Construction
[0009] The present invention will be further described below in conjunction with the drawings and descriptions of the drawings.
[0010] A lightweight air duct for high-speed trains, comprising an air duct 1, the air duct 1 is made of a light-core steel plate, the section of the air duct 1 adopts a streamlined design, and cold-proof cotton is pasted on the surface of the inner cavity of the air duct 1. In the present invention, the air duct 1 is made of light-core steel as the basic material through CNC machining, bonding, forming and other processes.
[0011] Light core steel is a new type of composite material. The material mainly has the characteristics of low density, high strength, good sound insulation, and good heat preservation. The light core steel is used as the basic material, and it is made according to the drawings through CNC processing, bonding, forming and other processes. For the required air duct products, the air duct section adopts a streamlined design, whi...

The invention relates to a lightweight air duct for high-speed trains, which belongs to the technical field of air ducts for trains and includes air ducts. The air ducts are made of light core steel plates, the section of the air ducts adopts a streamlined design, and the surface of the inner cavity of the air ducts is pasted to prevent cold cotton. The air duct uses light core steel as the basic material, and is manufactured through CNC machining, bonding, and forming processes. The invention has a reasonable and simple structure and is easy to manufacture. The lightweight air duct for high-speed trains provided by the invention is based on a light core steel plate, processed into a required shape by CNC, and then bonded and formed by an adhesive. The surface of the inner cavity of the air duct is pasted Cold cotton. The streamlined air duct design and the material characteristics of light core steel have realized many advantages such as light weight, high strength, aging resistance, sound insulation and heat insulation, and stable performance of air duct products.
Description
technical field [0001] The invention relates to a lightweight air duct for high-speed trains, belonging to the technical field of air ducts for trains. Background technique [0002] The rail vehicle ventilation system is a very important system in the whole vehicle, responsible for the air circulation and temperature adjustment of each workshop. It is the core component of rail trains. At present, domestic rail vehicle manufacturers mainly have two options for the selection of vehicle ventilation systems: 1. Ordinary aluminum plate air ducts, 2. FRP air ducts. In reality, the air ducts made of these two materials have many shortcomings: the air ducts made of ordinary aluminum plates have simple structures, do not have the characteristics of sound insulation and heat insulation, and the loss of hot and cold air is very high when they are transmitted inside. Large, and then there are simple aluminum products that are not high in strength and easy to deform. FRP air duct is ...
