L'invention concerne un évaporateur et un climatiseur comportant l'évaporateur. L'évaporateur comprend une ailette (a220), un tuyau de fluide frigorigène, destiné à la circulation de fluide frigorigène, étant disposé sur l'ailette (a220) et une entrée de fluide frigorigène et une sortie de fluide frigorigène étant disposées d'un premier côté de l'ailette (a220), l'évaporateur comprenant en outre un tuyau d'entrée de liquide (a2231) et un tuyau collecteur de gaz (a2232) reliés respectivement à l'entrée de fluide frigorigène et à la sortie de fluide frigorigène. Le tuyau d'entrée de liquide (a2231) et le tuyau collecteur de gaz (a2232), utilisés pour relier une unité extérieure de climatiseur, s'étendent à partir du premier côté et/ou d'un second côté de l'ailette (a220), et au moyen de la structure des tuyaux s'étendant à partir des deux côtés de l'ailette (a220) et du tuyau collecteur de gaz (a2232), un membre du personnel d'installation peut choisir, en fonction de la position d'installation du climatiseur, d'effectuer un raccordement des tuyaux des unités intérieure et extérieure à partir du côté relativement plus proche de l'ailette, ce qui permet d'éviter le défaut technique concernant le pliage excessif des tuyaux provoqué par une position d'assemblage opposée à la direction de raccordement des tuyaux pendant l'installation.
