Abstract

La présente invention concerne un dispositif de climatisation de véhicule et, plus spécifiquement, un dispositif de climatisation de véhicule qui comprend une porte de régulation de température de type dôme et une porte avant de type dôme qui sont installées de façon rotative, respectivement, dans une région de mélange d'un boîtier de climatiseur et, par conséquent, l'effet de réduction de la résistance à l'écoulement et d'augmentation du volume d'air peut être obtenu par le fait que la surface incurvée interne de la porte de régulation de température et la surface incurvée interne de la porte avant guident régulièrement l'air vers des évents respectifs selon un mode d'évacuation d'air.
