Rail train and side wall thereof

Abstract

The invention discloses a rail train side wall which comprises a wall body and a glass window mounted on the wall body. The wall body comprises an inner wall board and an outer wall board which are mutually connected, the wall body is of a double-layer interlayer structure, a separated cavity used for conveying air-conditioning airflow is formed in the middle of the wall body, the upper end of theseparated cavity is located on the upper part of the wall body and provided with an air inlet used for communicating with an air supply channel at the top of a carriage, and the lower end of the separated cavity is located on the lower part of the wall body and provided with an air outlet communicating with the interior of the carriage. Warm air generated by a warming system enters the separatedcavity from the air inlet and then is conveyed into the carriage through the air outlet in the bottom of the carriage, warming uniformity is guaranteed by utilizing a heat convection principle, and thus the side wall has a warming function, the temperature of the side wall is guaranteed in a cold environment, and the overall temperature comfort in the carriage is improved. The invention further discloses a rail train comprising the side wall.

Description

technical field [0001] The invention relates to the field of trains, in particular to a side wall of a rail train. In addition, the present invention also relates to a rail train comprising the above-mentioned side wall. Background technique [0002] In order to improve ride comfort, if it is running in a cold environment, it is necessary to install a heating system on rail trains such as high-speed EMUs. [0003] Existing track train generally is to carry out heating by arranging heater system. The air supply channel of the heating system is set on the top of the car. According to the principle of thermal convection, the hot air is mainly concentrated in the upper space, and the cold air is mainly concentrated in the lower space. The heating effect is not good. The body and the glass windows installed on the wall, the wall includes the interconnected inner wall panels and outer wall panels, which are only used as a supporting structure and cannot play a role in heating th...

Problems solved by technology

The air supply channel of the heating system is set on the top of the car. According to the principle of thermal convection, the hot air is mainly concentrated in the upper space, and the cold air is mainly concentrated in the lower space. The heating effect is not good. The body and the glass windows installed on the wall, the wall includes the interconnected inner wall panels and outer wall panels, which are only used as a supporting structure and cannot play a role in heating the compartment, although there are interior parts inside the wall, It can play a certain role in heat insulation, but the wall with too low temperature will still absorb the heat of the hot air in the car, and continuously conduct the heat to the outside, seriously affecting the heating and heat preservation effect in the car
