Title (EN) HEAT EXCHANGER
(FR) ÉCHANGEUR DE CHALEUR
(JA) 熱交換器
Abstract:
(EN) [Problem] To provide a heat exchanger configured so that an air flow passage is prevented from being closed by frost, and so that the heat exchanger has improved heat exchange efficiency. [Solution] Regions surrounded by tubes 13 and fins 14 are defined as air flow passages 21 through which air flows in a width direction. The fins 14 have extended sections 23 extended further toward the windward side in the width direction than the air flow passages 21. The tubes 13 have protrusions 24 protruding further toward the windward side in the width direction than the air flow passages 21.
(FR) Le problème décrit par la présente invention est de pourvoir à un échangeur de chaleur conçu pour empêcher la fermeture d'un passage d'écoulement d'air par le givre, et pour améliorer l'efficacité d'échange de chaleur de l'échangeur de chaleur. La solution de l'invention porte sur des régions, entourées par des tubes (13) et des ailettes (14), définies en tant que passages d'écoulement d'air (21) aptes à être traversés par un écoulement d'air dans la direction de la largeur. Les ailettes (14) comportent des sections étendues (23) s'étendant davantage vers le côté amont dans la direction de la largeur par rapport aux passages d'écoulement d'air (21). Les tubes (13) comportent des protubérances (24) faisant saillie davantage vers le côté amont dans la direction de la largeur par rapport aux passages d'écoulement d'air (21).
(JA) 【課題】着霜による通風路の閉塞を抑制すると共に、熱交換効率の向上を図る。 【解決手段】チューブ13とフィン14とで囲まれた領域を、幅方向に空気を流すための通風路21とし、フィン14は、幅方向に沿って通風路21よりも風上側に延長させた延長部23を備える。チューブ13は、幅方向に沿って通風路21よりも風上側へ突出する突出部24を備える。
