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.
提供一种轨道工程车用轻型风道,在左侧风道和右侧风道两侧壁上均设有多个与其内部出风通道连通的出风口连接管,左侧风道右侧中部和右侧风道左侧中部均镶嵌有出风口和入风口分别与其内部的出风通道和入风通道连通的安装支座,安装支座的出风口与内室出风格栅的入风口连通而安装支座的入风口与车体风道连通,左侧风道和右侧风道上下两端部均固定有与其内部的出风通道连通的末端出风口连接座,左侧风道和右侧风道上设有多个用于与车体固连的连接板。本发明通过优化左侧风道和右侧风道的结构和材料,改善风道通风均匀性的同时,大大降低了风道的重量,隔音降噪效果好,满足风道轻量化要求,保证强度的前提下满足空调送风要求。
