Embodiment Construction

[0013] Embodiments of the present invention will be explained below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown, the multifunctional air duct for rail vehicles in this embodiment is made of a non-metallic plate with a thickness of 10mm, and is made by bonding and riveting. The upper surface of the air duct body 1 is provided with an air supply inlet 2, which is sealed and docked with the air outlet of the air conditioner; at the same time, the upper surface of the air duct body 1 is also provided with a waste discharge port 5, through which the exhaust gas in the car is connected to the waste exhaust inside the air conditioning unit. import office. The air duct body 1 is designed in layers, the lower layer is the air supply chamber A, the upper layer is the waste discharge chamber B, and the air supply chamber A and the waste discharge chamber B are separated by a partition 6 . An air outlet 3 connected to the air supply chamber A and a ...

Abstract

The invention relates to a multifunctional air duct for a rail vehicle, comprising an air duct body with an air supply cavity, an air supply inlet and an air outlet arranged in the air duct body, wherein the air duct body is further provided with a waste discharge cavity, a waste discharge inlet and an waste discharge outlet communicated with the waste discharge cavity; the waste discharge cavityis isolated from the air supply cavity. As the multifunctional air duct integrates the functions of air supply and waste discharge, an integral structure is formed, thus solving the problems of shortage of vehicle installation space, great design difficulty and difficult installation process.

Description

technical field [0001] The invention relates to the technical field of rail vehicle air conditioners, in particular to air duct design and installation. Background technique [0002] At present, the air-conditioning system adopts a single-function air supply duct, which does not integrate the waste discharge function. The vehicle is equipped with a waste exhaust duct separately, which occupies the interior space of the vehicle. It is necessary to consider the layout of various professional equipment to determine the location of the waste exhaust duct, and the process installation and cost are relatively high. [0003] After searching, it was found that the Chinese invention patent application CN 103158730 A discloses an air-conditioning duct system for intercity EMUs. The air supply duct of the air conditioner is set on the roof, and the waste exhaust duct is set in the floor and under the train. . On the one hand, the exhaust air duct occupies the space inside and under t...
