Abstract

La présente invention concerne un ensemble tube à ailettes spiralé amélioré (24, 24A, 24B, 24C, 24D) améliorant les performances de l'échangeur de chaleur par évaporation (26, 26A, 26B, 26C, 26D) et comprenant des tubes (10), de préférence des serpentins, dans l'ensemble spiralé. Les tubes présentent une section transversale généralement elliptique pourvue d'ailettes externes (20) formées sur une surface externe des tubes. Les ailettes sont disposées à une distance de sensiblement 1,5 à sensiblement 3,5 ailettes par pouce (2,54 cm) le long de l'axe longitudinal (13) des tubes, s'étendent sensiblement sur 23,8 % à sensiblement 36 % du diamètre extérieur du tube nominal en hauteur depuis la surface externe des tubes et présentent une épaisseur de sensiblement 0,007 pouce (0,018 cm) à sensiblement 0,020 pouce (0,051 cm). Les tubes présentent un espacement de centre à centre (DH) généralement horizontal et perpendiculaire à l'axe longitudinal des tubes de sensiblement 109 % à sensiblement 125 % du diamètre extérieur de tube nominal et un espacement de centre à centre généralement vertical (Dv) de sensiblement 100 % à environ 131 % du diamètre extérieur de tube nominal.
