Abstract

The invention relates to an assembly of a wall (6) of a railway vehicle (2) and at least one electrical device (8), including a plurality of electrical components arranged in at least one compartment (10) and at least one cooler arranged in at least one pipe (12) defining a main flow direction of the coolant for the components, characterised in that the electrical device (8) is positioned in the wall (6) such that the flow direction is vertically arranged.

Description

technical field [0001] The invention relates to an assembly of a wall of a railway vehicle and at least one electrical device. [0002] The invention also relates to a corresponding railway vehicle. [0003] The invention relates more particularly to the field of power electrical equipment carried in trains, in particular auxiliary power converters. Background technique [0004] Such devices typically include a number of electrical components that need to be cooled to function properly. [0005] These electrical devices therefore generally comprise one or more heat exchangers, hereinafter referred to as coolers. These coolers are usually arranged in a duct which determines the direction of the main circulation of the cooling fluid of the component. [0006] The power electrical equipment, in particular the auxiliary converter, is arranged on the roof or under the floor of the train. For the traction converter operating the engine, the dissipated power is directly related...
