Abstract

L'invention concerne un dispositif destiné à réguler la température d'objets, en particulier afin de sécher des carrosseries ou des parties de carrosserie dotées d'un revêtement. Ledit dispositif comporte une enveloppe (18) et un tunnel de régulation de température (20) logé dans l'enveloppe (18). Un système de régulation de température (42) destiné à réguler la température des objets (14) avec un fluide gazeux régulé en température comporte des buses de fluide (46, 66) qui permettent chacune de projeter un jet de fluide sur les objets (14). Selon l'invention, un système d'aspiration (32) permet d'aspirer l'atmosphère dans le tunnel par un ou plusieurs orifices d'aspiration (34a) de manière à générer dans le tunnel de régulation de température (20) un écoulement de base en direction d'un ou plusieurs orifices d'aspiration (34a). La présence d'un système de convection (68) permet de générer, en plus d'un écoulement de base, un écoulement de convection qui renforce l'écoulement de base.
