Title (EN) HEAT EXCHANGER AND ASSOCIATED TUBE
(FR) ÉCHANGEUR THERMIQUE ET TUBE ASSOCIÉ
Abstract:
(EN) The invention concerns a heat exchanger (1) with mechanical assembly, comprising a plurality of heat exchange elements (5), and a plurality of tubes (3) mechanically assembled to the heat exchange elements (5), the tubes (3) respectively comprising an outer casing (30) delimiting a channel for the flow of a first fluid, and said heat exchanger (1) being configured for the flow of a second fluid around the tubes (3) and between the heat exchange elements (5) in a general direction of flow (E). According to the invention, the outer casings (30) of the tubes (3) have, in cross-section, a profile shape comprising: - at one end, a leading edge (31) configured to face towards the second fluid, - at the other end, a trailing edge (33) configured to be downstream of the leading edge (31) in the general direction of flow (E) of the second fluid, and - a substantially curved extrados surface (35) and an intrados surface (37), joined by the leading edge (31) and the trailing edge (33). The invention also concerns a tube (3) for such a heat exchanger (1).
(FR) L'invention concerne un échangeur thermique (1) à assemblage mécanique, comprenant une pluralité d'éléments d'échange thermique (5), et une pluralité de tubes (3) assemblés mécaniquement aux éléments d'échange thermique (5), les tubes (3) comprenant respectivement une enveloppe externe (30) délimitant un canal pour la circulation d'un premier fluide, et ledit échangeur (1) étant configuré pour la circulation d'un deuxième fluide autour des tubes (3) et entre les éléments d'échange thermique (5) selon une direction générale d'écoulement (E). Selon l'invention, les enveloppes externes (30) des tubes (3) présentent respectivement en section transversale une forme profilée comprenant : - à une extrémité un bord d'attaque (31) configuré pour faire face au deuxième fluide, - à l'autre extrémité un bord de fuite (33) configuré pour être en aval du bord d'attaque (31) selon la direction générale d'écoulement (E) du deuxième fluide, et - une surface d'extrados (35) sensiblement courbée et une surface d'intrados (37), jointes par le bord d'attaque (31) et le bord de fuite (33). L'invention concerne également un tube (3) pour un tel échangeur thermique (1).
