Title
(EN) TUBE HEAT EXCHANGER WITH OPTIMIZED THERMO-HYDRAULIC CHARACTERISTICS
(FR) ÉCHANGEUR DE CHALEUR À TUBES AVEC CARACTÉRISTIQUES THERMOHYDRAULIQUES OPTIMISÉES
Abstract
(EN)
A tube heat exchanger comprising at least one tube extending along a certain axial direction, each tube being provided with heat exchange fins (4) spaced apart from one another along said axial direction and extending radially from said tube, each fin (4) being relief structured to form dimples and a groove/rib (5) arranged at a first distance from said tube, characterized in that said dimples (6) are placed on the outside of the groove/rib and arranged in at least one line surrounding the said groove/rib structure at a second distance from said tube greater than said first distance and in that said groove/rib (5) has a depth along said axial direction greater than the depth of said dimples (6).
(FR)
L'invention concerne un échangeur de chaleur à tubes comportant au moins un tube s'étendant suivant une certaine direction axiale, chaque tube étant muni d'ailettes (4) d'échange de chaleur espacées les unes par rapport aux autres suivant ladite direction axiale et s'étendant radialement à partir dudit tube, chaque ailette (4) étant structurée en relief pour former des cuvettes et une rainure/nervure (5) disposées à une première distance dudit tube, caractérisées en ce que lesdites cuvettes (6) sont placées sur l'extérieur de la rainure/nervure et disposées en au moins une ligne entourant ladite structure de rainure/nervure à une deuxième distance dudit tube supérieure à ladite première distance, et en ce que ladite rainure/nervure (5) présente une profondeur suivant ladite direction axiale supérieure à la profondeur desdites cuvettes (6).
