Abstract

Selon l'invention, un élément installation (7) qui possède une pluralité de parois verticales (19) se dressant vers le haut depuis une face plancher (5), et une paroi face supérieure (21) connectant entre elles les parties supérieures des parois verticales (19), est agencé sur la face plancher (5). Un appareil de conversion de puissance (9) est disposé côté inférieur de la paroi face supérieure (21) de l'élément installation (7), dans un état de séparation par rapport à la face plancher (5) dans la direction verticale. Ledit appareil de conversion de puissance (9) refroidit une partie interne en admettant et déchargeant un air (135) à la périphérie. Ainsi, l'appareil de conversion de puissance (9) est disposé séparément au-dessus de la face plancher (5), ne risquant pas ainsi d'admette la poussière, les impuretés, ou similaire, se trouvant sur la face plancher (5), et les performances de refroidissement sont préservées à un haut niveau.
