Title (EN) HEAT EXCHANGER FOR A BOILER, AND HEAT-EXCHANGER TUBE
(FR) ÉCHANGEUR DE CHALEUR POUR CHAUDIÈRE, ET TUBE D'ÉCHANGEUR DE CHALEUR
Abstract:
(EN) A heat exchanger for a heating device, such as a boiler, comprises a tube assembly (10), which includes a plurality of tubes (1) arranged in a juxtaposed configuration, and at least one first manifold member (11) on the outside of the tube assembly (10). Each tube (1) is wound in a spiral having a plurality of substantially co-planar turns (2a, 2b, 2c), amongst which at least one inner turn (2a) and at least one further turn (2b, 2c) around the inner turn (2a), the at least one further turn (2b, 2c) comprising at least one outer turn (2b) of the spiral. At least one first tube (1), or each tube, of the plurality of tubes has a first end portion (3), which extends starting from the inner turn (2a) towards the outside of the corresponding spiral, with at least one part (30) of the first end portion (3) that is superimposed on the at least one further turn (2b, 2c) in a position corresponding to a major face of the spiral, for connection to the at least one first manifold member (11). The at least one first tube (1), or each tube, of the plurality of tubes, has at least one transverse depression (6) defined in the at least one further turn (2b, 2c), or in each further turn, in which a corresponding part (30) of the first end portion (3) is at least partially received.
(FR) L'invention concerne un échangeur de chaleur pour un dispositif de chauffage, tel qu'une chaudière, l'échangeur comprenant un ensemble (10) de tubes comportant une pluralité de tubes (1) agencés en configuration juxtaposée, et au moins un premier élément collecteur (11) sur l'extérieur de l'ensemble (10) de tubes. Chaque tube (1) est enroulé en spirale, la spirale comportant une pluralité de spires sensiblement coplanaires (2a, 2b, 2c) comprenant au moins une spire interne (2a) et au moins une spire supplémentaire (2b, 2c) autour de la spire interne (2a), ladite spire supplémentaire (2b, 2c) comprenant au moins une spire externe (2b) de la spirale. Au moins un premier tube (1), ou chaque tube, parmi la pluralité de tubes présente une première partie d'extrémité (3) s'étendant à partir de la spire interne (2a) vers l'extérieur de la spirale correspondante, au moins une partie (30) de la première partie d'extrémité (3) étant superposée sur ladite spire supplémentaire (2b, 2c) dans une position correspondant à une face principale de la spirale, pour son raccordement audit premier élément collecteur (11). Ledit premier tube (1), ou chaque tube, parmi la pluralité de tubes, comporte au moins un enfoncement transversal (6) défini dans ladite spire supplémentaire (2b, 2c), ou dans chaque spire supplémentaire, une partie correspondante (30) de la première partie d'extrémité (3) étant reçue au moins partiellement dans ledit enfoncement.
