Title
(EN) FINNED TUBE HEAT EXCHANGER
(FR) ÉCHANGEUR DE CHALEUR À TUBE À AILETTES
(JA) フィンチューブ熱交換器
Abstract
(EN) This finned tube heat exchanger (100) is provided with: a plurality of fins (31) arranged in parallel; and a heat transfer tube (21) configured in a manner so that a medium that exchanges heat with air flows therewithin. The fins (31) are corrugated fins formed in a manner so that a hill section (34) appears in at least one position in the direction of airflow, and include: a tube periphery section (35 or 37) formed at the periphery of the heat transfer tube (21); a first inclined section (38) tilted with respect to the direction of airflow in a manner so as to form the hill section (34); a second inclined section (39) connecting the tube periphery section (35) and the first inclined section (38) to each other; and a slit (23) formed in the second inclined section (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).
(JA)  フィンチューブ熱交換器100は、平行に並べられた複数のフィン31と、空気と熱交換する媒体が内部を流れるように構成された伝熱管21とを備えている。フィン31は、気流方向における少なくとも1つの位置に山部34が現れるように成形されたコルゲートフィンであって、伝熱管21の周囲に形成された管周囲部35(又は37)と、山部34を形成するように気流方向に対して傾いている第1傾斜部38と、管周囲部35と第1傾斜部38とを互いに接続している第2傾斜部39と、第2傾斜部39に形成されたスリット23を含む。
