Abstract

L'agitateur est constitué d'une bande de matière tordue en hélice et dont la section droite présente une forme à double inflexion en sens opposés. La double inflexion est obtenue par inclinaison des portions latérales 3 de part et d'autre d'une portion centrale 7. Application aux échangeurs de chaleur tubulaires.
