Aluminum shell of track compartment air conditioning unit

Abstract

The invention provides an aluminium shell of a track compartment air conditioning unit, which is completely made of aluminium alloy material, adopts a tube cavity internally provided with an aluminium alloy square tube or a rectangular tube having enhanced bulges to prepare an aluminium section framework, and uses aluminium alloy tubing and slabs to prepare the aluminum shell structure part; the aluminum shell structure part is the lower structure of the aluminium shell, while the aluminium section framework is the upper structure of the aluminium shell; and the aluminium section framework isformed by more than two groined aluminum tube frames, and is arranged in the aluminium shell structure to form an integrated aluminium shell. The invention has the beneficial effects of greatly lowering the weight of the shell structure of the air conditioning unit, lessening compact thereof on the track compartment, reducing design difficulty and manufacture cost of the track compartment, and enabling the manufacturing of the new track compartment to be in line with the requirements of technology development better.

Description

【Technical field】 [0001] The invention relates to the technical field of rail car manufacturing, in particular to the manufacturing technology of a rail car air-conditioning unit, in particular to an aluminum shell of a rail car air-conditioning unit. 【Background technique】 [0002] In response to the development of urban transportation, subways and light rails are transportation projects that some big cities are vigorously developing. Therefore, the application of rail transportation is increasing, and the demand for rail cars is increasing. Due to the special environment of rail transit and the huge passenger flow, ventilation and air conditioning facilities are very important in the design and use of rail cars. Therefore, air conditioning units have become an important part of rail cars. Structurally speaking, the air conditioning unit is generally arranged on the roof of the rail car through the shell structure. At present, the structural parts of the shell of the air c...

AI Technical Summary

Problems solved by technology

[0003] At present, although the shell structure of the steel structure of the air-conditioning unit has high hardness and good strength, its own weight is too heavy, and the corresponding structure of the rail car is required to support it. Therefore, the design requirements for the structure of the rail car are very high. Costs to manufacture, install and transport rail cars remain high

In addition, the manufacturing technology of rail cars is developing in the direction of light weight, and the use of lightweight aluminum alloy materials is one direction. Therefore, the structural parts of the air-conditioning unit shell with a steel structure that is too heavy will not meet the development requirements of rail cars
