Abstract[English]
The present invention relates to an insert for a tube (10) of a heat exchanger tube, in particular a two-phase heat exchanger, for improving the heat transfer efficiency and optionally 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 has an element which can be static or, preferably, rotatably movable and comprises several successive series of a first portion (S1) in the form of a spring and a second portion (S2) in the form of a straight rod.[French]
La présente invention concerne un insert pour tube (10) d'échangeur de chaleur, en particulier diphasique, pour améliorer l'efficacité de transfert thermique et éventuellement 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, statique ou de préférence mobile en rotation, comprenant un enchainement de plusieurs successions d'une première section (S1) en forme de ressort et d'une deuxième section (S2) à tige droite.
