Abstract[English]
The present invention relates to an insert for a heat exchanger tube (10) for improving the heat transfer efficiency and/or reducing the fouling of the heat exchanger tubes of industrial units, for example units used in the fields of petroleum refining, petrochemistry or chemistry in general. The insert comprises a rotatably movable element in the form of a spring (1) having a pitch p1 that is smaller at the inlet of the tube (10) as compared with the rest of the movable element.[French]
La présente invention concerne un insert pour tube (10) d'échangeur de chaleur pour améliorer l'efficacité de transfert thermique et/ou réduire l'encrassement des tubes d'échangeurs de chaleur d'unités industrielles, par exemple des unités mises en œuvre dans les domaines du raffinage du pétrole, de la pétrochimie ou de la chimie en général. L'insert comporte un élément mobile rotatif en forme de ressort (1) comportant un pas p1 plus resserré en entrée du tube (10) par rapport au reste de l'élément mobile.
