Title (EN) MULTI-LEVEL HEATING COIL BUNDLE
(FR) FAISCEAU DE SERPENTINS DE DE CHAUFFAGE À PLUSIEURS NIVEAUX
Abstract:
(EN) In an embodiment of the invention, a heating coil bundle (20) for a tank (10) heating comprising one heating coil body and three supports (40) is disclosed. The bundle (20) is comprised of a plurality of straight tubes (32) and a plurality of U-shaped tubes (34) that are leak-proof serially joined at their open ends and extended in parallel and spaced-apart relationship to each other and arranged in a plurality of levels (24). The bundle (20) cross-section is characterized by a binary-matrix-like tube pattern (22) of M rows (24) and N columns (26). The disclosed heating coil bundle (20) generates a heated fluid (50) large-scale circulation (52) and superimposes said large-scale circulation (52) driven forced convection on a buoyancy driven natural convection, providing a more effective heat transfer mechanism.
(FR) Dans un mode de réalisation de l'invention, un faisceau de serpentins de chauffage (20) pour chauffer un réservoir (10) comprend au moins un corps de serpentin de chauffage et trois supports (40). Le faisceau (20) comprend une pluralité de tubes droits (32) et une pluralité de tubes en forme de U (34) qui sont reliés en série de manière étanche aux fuites, au niveau de leurs extrémités ouvertes, s'étendent de manière parallèle et espacée les uns par rapport aux autres, et sont disposés en une pluralité de niveaux (24). La section transversale du faisceau (20) est caractérisée par un motif de tubes de type matrice binaire (22) formé par M rangées (24) et N colonnes (26). Le faisceau de serpentins de chauffage (20) selon l'invention génère une circulation à grande échelle (52) de fluide chauffé (50) et superpose la convection forcée, entraînée par ladite circulation à grande échelle (52), à une convection naturelle entraînée par la flottabilité, ce qui permet d'obtenir un mécanisme de transfert de chaleur plus efficace.
