Abstract: A traction box of a railway vehicle includes pieces of electric equipment; and a cooling device including a first and second fluid circuits, respectively crossing first and second heat exchange areas with the pieces of electric equipment; and first and second of heat exchangers, respectively crossed by the first and the second fluid circuits and allowing heat exchange between the fluid and a first air flow. The fluid circuits include a first common conduit for fluid circulation, crossing the first exchanger, and then connected to the second and to a third parallel conduits, the second conduit belonging to the second fluid circuit and first crossing the second exchanger and then the second heat exchange area.

Abstract: The application relates to a power module (10) including: pieces of electrical equipment (12), at least first (14) and second (16) electronic cards, and a cooling device (20), able to discharge the heat given off by the pieces of electrical equipment and electronic cards. The cooling devices include first (34) and second (36) surfaces thermally insulated from one another, the pieces of electrical equipment (12) being in thermal contact with the first surface and separated from the second surface. The first electronic card (14) is fastened to a piece of electrical equipment (12) and thermally connected to the second surface (36) of the cooling device by a heat sink (42). The second electronic card (16) is positioned close to the second surface (36), or in contact with the second surface.
