Abstract

The invention relates to the technical field of train air conditioner installation, in particular to a train top holder, a train air conditioner installation structure and a train. The train top holder comprises a train top plate, enclosing plates and supporting parts, wherein a plurality of through holes are formed in the train top plate, and flangings around the through holes are arranged on thepositions, at the edges of the through holes, of the train top plate; the enclosing plates are installed on the upper surface, away from a passenger room, of the train top plate, and arranged relative to the flangings, and the enclosing plates and the flangings are enclosed to form U-shaped grooves; the U-shaped grooves are formed around the edges of the through holes; and the supporting parts are installed on the lower surface, close to the passenger room, of the train top plate. The through holes are formed in the train top plate of the train top holder, the flangings are arranged at the edges of the through holes, and the flangings and the enclosing plates are enclosed to form the U-shaped grooves. During installation of an air conditioner, sealing joint strips can be installed in theU-shaped grooves, thus the sealing installation problem is solved. During installation of the air conditioner, the air conditioner is directly installed on the train top plate, sinking installation isnot required, and the space in a carriage is saved.

Description

technical field [0001] The invention relates to the technical field of train return air, in particular to a train roof frame, a train air-conditioning installation structure and a train. Background technique [0002] In my country, trains, especially fast trains, have become an important means of transportation for people to travel. After many railway speed increases, my country's railway passenger transport has entered the high-speed era of about 300km / h, and the design speed has been increased to 400km / h. Existing trains are equipped with air-conditioning equipment, and train air-conditioning units have gradually become one of the basic components of modern rail passenger vehicles. They are used to adjust the temperature and humidity in the passenger compartment, improve the air quality in the passenger compartment, and meet the comfort requirements of the passenger compartment. The train passenger room air conditioning unit is mainly composed of shell, evaporator, conden...
