Title (EN) TUBE HEAT EXCHANGER
(FR) ECHANGEUR DE CHALEUR A TUBES
Abstract:
(EN) A tube heat exchanger comprises a set of tubes (14) which tubes have a non-round cross-section form with a constant wall thickness and with projecting ridges (15) that are formed of the tube wall, which ridges extend helically round the centre line (2) of the tube. The tubes directly support against each other via the ridges and the tubes are so twisted relative to each other that in each cross-section through the set of tubes there is formed a number of similarly formed passages (9) between the tubes.
(FR) Un échangeur de chaleur à tubes comporte un ensemble de tubes (14) qui ont une forme de section transversale non arrondie et une épaisseur constante des parois, ainsi que des arêtes (15) saillantes formées par la paroi du tube, arêtes qui s"étendent hélicoïdalement autour de l"axe (2) du tube. Les tubes se soutiennent directement entre eux par les arêtes et ils sont torsadés les uns par rapport aux autres de telle façon que dans chaque coupe transversale de l"ensemble de tubes est formé un certain nombre de passages (9) de formation similaire entre les tubes.
