  • the U-shaped (U-shaped) support member 6 (see FIG. 5) is taken as an example in the longitudinal cross section, but the support member 6 is substantially H in the longitudinal cross section. It may be a single member formed by extrusion of a shape.
  • the support member 6 includes the support plate portion 62 disposed in the horizontal direction, the opposing plate portion 63 formed shorter than the support plate portion 62 and disposed horizontally, the support plate portion 62, and the opposing plate portion 63. And a substrate portion 60 provided between them.
  • the support member 6 is formed into a substantially H shape in a longitudinal cross section, the area of the opposing plate portion 63 is smaller than the area of the support plate portion 62, so the air resistance can be reduced.
  • the substrate portion 60 of the support member 6 may be reinforced by forming a concave groove or a convex portion in a longitudinal cross section extending in the front-rear direction.
  • the vertical length of the folded plates 65B and 65F shown in FIG. 7 and FIG. 11 is the same as the vertical length of the upstream rectifying plates 64B and 64F as an example, You may change it suitably.

  • 67G demonstrated the case where it formed toward the airflow direction (upper and lower direction), you may make it incline with respect to the airflow direction, and may arrange
  • the opposing plate portions 63 and 63D shown in FIGS. 5 and 9 and the upstream opposing plate portions 66C and 66G shown in FIGS. 8 and 12 may be disposed obliquely with respect to the air flow direction. Further, the opposing plate portions 63 and 63D and the upstream side opposing plate portions 66C and 66G may be formed by bending the tip end portion obliquely with respect to the downstream direction.

Abstract

La présente invention concerne une unité extérieure (1) pour un climatiseur qui comprend : un échangeur de chaleur (2) pour échanger de la chaleur avec l'air extérieur ; un ventilateur (4) pour générer un courant d'air pour favoriser l'échange de chaleur dans l'échangeur de chaleur (2) ; un moteur (5) pour entraîner le ventilateur (4) ; un boîtier (7) dans lequel est agencé le ventilateur (4) et le moteur (5) ; et un élément de support (6) monté de part et d'autre de l'intérieur du boîtier (7). L'élément de support (6) comporte : une section de plaque de base (60) formée dans la direction du courant d'air ; une section de plaque de support (62) s'étendant depuis le côté aval de la section de plaque de base (60) de façon à faire face à la direction du courant d'air ; et une section de plaque opposée (63) s'étendant depuis le côté amont de la section de plaque de base (60) de façon à faire face à la direction du courant d'air et s'étendant à un degré inférieur au degré d'extension de la section de plaque de support (62). L'élément de support (6) présente une forme de section transversale sensiblement en forme de U.
