Abstract

L'invention concerne un réfrigérateur équipé d'un évaporateur (200). L'évaporateur (200) comprend un support (202) et un tube (204), disposé sur le support (202), qui sert à véhiculer le réfrigérant. Le tube (204) placé sur le support (202) comprend une première zone de tube (I), qui peut être parcourue sensiblement dans une première direction de transport, en particulier de haut en bas, dans la position de fonctionnement du réfrigérateur (100), et une seconde zone de tube (II) qui peut être parcourue sensiblement dans une seconde direction de transport, en particulier de bas en haut. Selon l'invention, la première zone de tube (I) comprend une partie (210a, 212a, 210b, 212b) et la seconde zone de tube (II) comporte une partie (214a, 214b), lesquelles parties sont imbriquées sur le support (202).
