Abstract

La présente invention concerne un dispositif de climatisation de véhicule qui est capable de traiter une quantité d'air requise. Le dispositif de climatisation de véhicule comporte un régulateur de température (4). Le régulateur de température (4) comprend un noyau d'élément chauffant (21). Des portes de mélange d'air (23c, 23d, 23e) sont disposées sur le côté amont du noyau d'élément chauffant (21). La quantité d'air traversant un passage d'élément chauffant (25c) est régulée par la porte de mélange d'air (23c). La quantité d'air traversant un passage d'élément chauffant (25e) est régulée par la porte de mélange d'air (23e). Un boîtier intermédiaire (44) comporte une unité de régulation (46). L'unité de régulation (46) augmente la surface du noyau d'élément chauffant (21) à travers laquelle l'air passe dans le passage d'élément chauffant (25c). L'unité de régulation (46) diminue la surface du noyau d'élément chauffant (21) à travers laquelle l'air passe dans le passage d'élément chauffant (25e). L'unité de régulation (46) régule une différence dans les quantités de chauffage des passages d'élément chauffant (25c, 25e) sans affecter la surface d'ouverture des portes de mélange d'air (23c, 23e) et similaires.
