Problems solved by technology
With the continuous improvement of the level of specialization, the integration of rail engineering vehicles is getting higher and higher, and product performance and light weight are particularly important. At present, aluminum air-conditioning ducts in rail engineering vehicles are heavy and have poor sound insulation and noise reduction effects. , and due to the defects in the design structure of the air duct, the uniformity of the air supply at each air outlet is poor. Therefore, it is necessary to improve the above problems

According to the light air duct for the track engineering vehicle, a plurality of air outlet connecting pipes communicated with air outlet channels in the left air duct and the right air duct are arranged on the two side walls of the left air duct and the right air duct; an air outlet and an air inlet of the installation support are respectively communicated with an air outlet channel and an air inlet channel inside the installation support, the air outlet of the installation support is communicated with the air inlet of the inner chamber air outlet grid, and the air inlet of the installation support is communicated with the vehicle body air channel. Tail end air outlet connecting seats communicated with the air outlet channels in the left air duct and the right air duct are fixed to the upper ends and the lower ends of the left air duct and the right air duct correspondingly, and a plurality of connecting plates used for being fixedly connected with a vehicle body are arranged on the left air duct and the right air duct. By optimizing the structures and materials of the left air duct and the right air duct, the weight of the air duct is greatly reduced while the ventilation uniformity of the air duct is improved, the sound insulation and noise reduction effects are good, the lightweight requirement of the air duct is met, and the air supply requirement of an air conditioner is met on the premise of ensuring the strength.
Description
technical field [0001] The invention belongs to the technical field of rail engineering vehicles, and in particular relates to a light air duct for rail engineering vehicles. Background technique [0002] Rail vehicles use air-conditioning ducts to connect the driver's cab and vents, which are mainly used for dispersal, ventilation and air-conditioning air supply, and are also one of the main sources of noise pollution. With the continuous improvement of the level of specialization, the integration of rail engineering vehicles is getting higher and higher, and product performance and light weight are particularly important. At present, aluminum air-conditioning ducts in rail engineering vehicles are heavy and have poor sound insulation and noise reduction effects. , and due to defects in the design structure of the air duct, the air supply uniformity of each air outlet is poor. Therefore, it is necessary to improve the above problems. Contents of the invention [0003] Th...
