Title
(EN) INDIRECTLY HEATED CAPILLARY AEROSOL GENERATOR
(FR) GÉNÉRATEUR D'AÉROSOL CAPILLAIRE INDIRECTEMENT CHAUFFÉ
Abstract
(EN)
An indirectly heated capillary aerosol generator comprises a capillary tube 10 adapted to form an aerosol when liquid material in the capillary tube is heated to volatilize at least some of the liquid material therein and a thermally conductive material 13 in thermal contact with the capillary tube. The indirectly heated capillary aerosol generator provides substantially even and uniform heating across the heated length of the capillary tube.
(FR)
La présente invention concerne un générateur d'aérosol capillaire indirectement chauffé qui comprend un tube capillaire (10) adapté de manière à former un aérosol quand une matière liquide dans le tube capillaire est chauffée afin de rendre volatile au moins une partie de la matière liquide dans celui-ci et un matériau thermiquement conducteur (13) en contact thermique avec le tube capillaire. Le générateur d'aérosol capillaire indirectement chauffé permet un réchauffement sensiblement égal et uniforme d'un bout à l'autre de la longueur réchauffée du tube capillaire.
