The existing train is provided with air conditioning equipment, and the train air conditioning unit gradually becomes one of basic components of a modern rail passenger room vehicle, is used for adjusting the temperature and the humidity in a passenger room, improving the air quality in the passenger room and meeting the requirement of the comfort level in the passenger room. The train passenger room air conditioning unit mainly comprises a shell, an evaporator, a condenser, a compressor, a throttling device, an evaporation fan, a condensation fan, a controller and the like.
China motor train units generally require that air conditioners are installed on roofs, and therefore air conditioner installation seats for installing the air conditioners are needed to be arranged on the roofs, the air conditioner installation seats are arranged on the roofs in a protruding mode, and the pneumatic performance of the whole motor train units is influenced to a large extent. With the high-speed development of rail vehicles, the vehicle speed is higher and higher, and the requirements on air resistance, comfort and vehicle appearance are higher and higher during vehicle design. The conventional air conditioner is installed on the outer part of the roof and cannot meet the requirement of high-speed running of the vehicle, so that the sinking installation of the air conditioner into the vehicle is a necessary trend of a high-speed train. A groove for accommodating the air conditioner is arranged on the vehicle roof, so that the air conditioner is supported through the vehicle roof, and the air conditioner is installed. However, the lower part of the air conditioner is sunk into the carriage, and occupies a large space at the top of the carriage, which is not beneficial to the utilization of the space in the carriage.

A roof plate 1 of the train roof frame is provided with a through hole 3, the edge of the through hole 3 is provided with a flange 2, and the flange 2 and a surrounding plate 4 are enclosed to form a U-shaped groove. When the air conditioner is installed, a sealing rubber strip can be installed in the U shape, and the problem of sealing installation is solved. When the air conditioner is installed, the air conditioner is directly installed on the roof plate 1, and does not need to be installed in a sinking mode, so that the space in a carriage is saved. The upper surface of roof board sets up the installation position that is used for the installation of air conditioner mounting bracket, through-hole 3 is used for installing the air exhaust passageway, return air passageway and/or the cable of air conditioner.
The enclosing plate 4 and the top surface of the roof plate 1 are fixedly connected or detachably connected (such as bolted connection, pin joint and the like), preferably fixedly connected, so that the connection stability is improved. Electric welding or arc welding can be used for the fixed connection. Spot welding can improve the face-to-face fit.
In some embodiments, as shown in fig. 3, the flange 2 and the roof panel 1 are of a unitary structure, and the roof panel 1 is directly turned into the flange 2 at the through hole 3. The two are not required to be welded, the structure is more stable, and welding operation is reduced. And the water leakage is avoided, and the sealing problem between the roof plate 1 and the flanging 2 is solved.
In other embodiments, the lower portion of the flange 2 is welded to the upper surface of the roof panel 1. The end face of the lower part of the flanging 2 is welded on the upper surface of the roof plate 1, and the upper surface of the roof plate 1 is used for installing an air conditioner. The welding can adopt spot welding mode, also can adopt arc welding, and preferred spot welding can increase the laminating degree of face of weld.
In order to form a U-shaped groove together with the turned-over edge 2, the enclosing plate 4 is in an L shape, the transverse branch of the L shape is fixedly connected to the upper surface of the roof plate 1, and the transverse branch extends towards the turned-over edge 2. The vertical branch and the horizontal branch are of an integrated structure, the water leakage problem cannot occur at the joint of the vertical branch and the horizontal branch, and the sealing problem of the joint is solved.
The integrated roof board 1, the flanging 2 and the integrated enclosing plate 4 are welded on the surface of the roof board 1 and the transverse branch of the enclosing plate 4 in a joint manner, and the formed U-shaped groove achieves better sealing performance. Wherein, spot welding is adopted for welding, and the joint degree of a welding surface can be improved.
