  • the spacer is provided with an extending portion that extends obliquely upward from the horizontal plane.
  • the condensed water from the heat exchanger can be more effectively guided to the drainage structure by the extending portion, corrosion of the heat exchanger and refrigerant leakage are prevented.

Abstract

L'invention concerne une unité à l'extérieur pour un dispositif de réfrigération utilisant un échangeur de chaleur construit à partir d'aluminium ou d'alliage d'aluminium et étant moins sujette à l'influence de la corrosion métallique. Une unité à l'extérieur (20) d'un dispositif de climatisation (1), l'unité à l'extérieure (20) correspondant à un mode de réalisation de la présente invention, est dotée d'un échangeur de chaleur (25) qui est construit à partir d'aluminium ou d'un alliage d'aluminium, d'un châssis inférieur (8) sur lequel l'échangeur de chaleur est placé, et d'un intercalaire (100) qui est placé entre l'échangeur de chaleur et le châssis inférieur. L'intercalaire a une surface inclinée (100a) et une surface horizontale (100b). La surface inclinée achemine l'eau de condensation, qui provient de l'échangeur de chaleur, jusqu'au châssis inférieur. La surface horizontale est en contact avec l'échangeur de chaleur et permet de placer l'échangeur de chaleur horizontalement dessus.
