Description

The present application claims priorities to Chinese Patent Application titled "RAIL TRAIN AND SIDEWALL THEREOF" and Chinese Utility Model Application titled "RAIL TRAIN AND SIDEWALL THEREOF" filed on December 27, 2017 with the China National Intellectual Property Administration, the disclosures of which are incorporated herein by reference.

Conventional rail trains are generally heated by providing a warm air system. An air supply passage of the warm air system is arranged on the top of a carriage, and according to the principle of thermal convection, hot air mainly gathers in an upper space, and cold air mainly gathers in a lower space.

The wall body includes an inner wall plate and an outer wall plate connected to each other, and only functions as a support structure rather than heating the inside of the carriage. Although built-in parts are arranged inside the wall body and can play a certain role in thermal insulation, the wall body with a too low temperature may absorb heat of the hot air inside the carriage, and continuously conduct the heat to the outside, thus seriously affecting the heating and thermal insulation effects inside the carriage.
Therefore, a technical issue to be addressed presently by those skilled in the art is to improve the heating and thermal insulation effects inside the carriage.
