Roof and air conditioner installation seat of railway vehicle

Abstract

The invention provides a roof and an air conditioner installation seat of a railway vehicle. Sunken installation of an air conditioner can be achieved, the influences on a roof streamline structure are reduced, air resistance and aerodynamic noise are lowered, and the aerodynamic performance of a train is improved. The air conditioner installation seat is arranged on the roof of the railway vehicle and is of a square frame structure, a middle cavity of the square frame structure is used for containing the air conditioner, the four sides of the square frame structure are edge beams made of hollow sectional materials, the inner sides of the edge beams are provided with air conditioner installation positions, the outer sides of the edge beams can be welded to the hollow sectional materials of the roof in an inserted mode, and the top faces of the side beams are each of an arc shape matched with the roof. The middle cavity of the square frame structure is used for containing the air conditioner, the whole air conditioner is conveniently arranged on the roof and cannot protrude out of the roof, sunken installation of the air conditioner is achieved, the influences of air conditioner installation on the roof streamline structure are effectively reduced, air resistance and aerodynamic noise are lowered, and the aerodynamic performance of the train is improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a roof of a rail vehicle and an air-conditioning installation seat thereof. Background technique [0002] At present, China's standard EMUs usually require that the air conditioner be installed on the roof. For this reason, the air conditioner mounting seat for installing the air conditioner needs to be installed on the roof. aerodynamic performance of the vehicle. [0003] Since the flow performance of the gas will be affected during the operation of the train, when the air conditioner is prominently installed on the roof, it is necessary to add an air conditioner shroud on the roof, which further increases the complexity of the roof equipment and increases the weight of the roof , and is not conducive to the assembly and disassembly of roof equipment. [0004] Furthermore, due to the large volume and weight of the air conditioner, the installation of the air conditioner...

Problems solved by technology

[0002] At present, China's standard EMUs usually require that the air conditioner be installed on the roof. For this reason, the air conditioner mounting seat for installing the air conditioner needs to be installed on the roof. aerodynamic performance of the vehicle

[0003] Since the flow performance of the gas will be affected during the operation of the train, when the air conditioner is prominently installed on the roof, it is necessary to add an air conditioner shroud on the roof, which further increases the complexity of the roof equipment and increases the weight of the roof , and it is not conducive to the assembly and disassembly of roof equipment

[0004] Furthermore, due to the large volume and weight of the air conditioner, the installation of the air conditioner cannot be realized in the form of installing grooves on the roof.

If a groove for accommodating the air conditioner is provided on the roof so that the air conditioner can be supported through the roof to realize the installation of the air conditioner, higher requirements will be placed on the strength of the roof; moreover, the space required for the installation of the air conditioner is relatively large , if a large groove is set on the roof, it is difficult to realize the connection of this groove with other parts of the roof
