Abstract

L'invention concerne un module à ventilateur de refroidissement (30) qui, lorsqu'il est vu dans le sens de la largeur du véhicule alors qu'il est monté sur le véhicule, possède un conduit côté aspiration d'air (33) qui est formé de manière à s'étendre du bas vers le haut dans le sens vertical par rapport à la carrosserie du véhicule, sous un ventilateur de refroidissement (31) le long de la forme externe d'un conduit côté échappement d'air (32), et à s'étendre ensuite vers un bloc de batterie (20) depuis une position à la même hauteur que le ventilateur de refroidissement (31) lorsque le module à ventilateur de refroidissement (30) est monté sur le véhicule. Une cavité (37) est formée sur la surface supérieure de la section étendue (38) du conduit côté aspiration d'air (33), la surface supérieure étant dirigée vers le haut lorsque le module à ventilateur de refroidissement (30) est monté sur le véhicule. Le module à ventilateur de refroidissement (30) est constitué du ventilateur de refroidissement (31), du conduit côté échappement d'air (32) et du conduit côté admission d'air (33).
