(EN) FIN TUBE HEAT EXCHANGER
(FR) ÉCHANGEUR DE CHALEUR À TUBE À AILETTES
Abstract
(EN) A fin tube heat exchanger (100) includes a plurality of fins (31) arranged in parallel and a heat transfer tube (21) configured to allow a medium to flow through the heat transfer tube to exchange heat with air. Each of the fins (31) is a corrugated fin formed to have a peak portion (34) at at least one position in an air flow direction, and has a tube surrounding portion (35 or 37) formed around the heat transfer tube (21), a first inclined portion (38) inclined with respect to the air flow direction to form the peak portion (34), a second inclined portion (39) connecting the tube surrounding portion (35) and the first inclined portion (38) to each other, and a slit (23) formed in the second inclined portion (39).
(FR) La présente invention concerne un échangeur de chaleur à tube à ailettes (100) pourvu : d'une pluralité d'ailettes (31) disposées en parallèle ; et d'un tube de transfert de chaleur (21) configuré de telle sorte qu'un milieu qui échange la chaleur avec l'air circule à l'intérieur de ce dernier. Les ailettes (31) sont des ailettes ondulées formées de telle sorte qu'une section colline (34) apparaît dans au moins une position dans le sens de l'écoulement d'air, et comprennent : une section périphérie de tube (35 ou 37) formée à la périphérie du tube de transfert de chaleur (21) ; une première section inclinée (38) inclinée par rapport au sens de l'écoulement d'air de façon à former la section colline (34) ; une seconde section inclinée (39) raccordant la section périphérie de tube (35) et la première section inclinée (38) l'une à l'autre ; et une fente (23) formée dans la seconde section inclinée (39).
