Abstract

L'invention concerne une étagère de réfrigération comprenant un groupe de base (11), un groupe paroi arrière (12) et un groupe supérieur (13) qui délimitent un compartiment de réfrigération (4) en bas, à l'arrière et au-dessus, qui sont au moins en partie pourvus de composants d'un dispositif de réfrigération (5) et qui présentent une structure multicouche dans laquelle est conçu un ensemble canal d'écoulement ; tant dans le groupe de base (11), dans le groupe paroi arrière (12) que dans le groupe toit (13) sont formés entre les couches respectives des interstices en tant que parties intégrantes de l'ensemble canal d'écoulement ; et l'interstice (11.6) inférieur formé dans le groupe de base (11) étant, sur sa face arrière, en liaison fluidique pour de l'air circulant avec une section inférieure de l'interstice (12.4) vertical formé dans le groupe paroi arrière (12) ; et l'interstice (13.7) supérieur formé dans le groupe supérieur (13) étant sur sa face arrière en liaison fluidique pour de l'air circulant avec une section supérieure de l'interstice vertical (12.4) formé dans le groupe paroi arrière (12) ; et un évaporateur ou autre échangeur de chaleur étant disposé dans l'interstice vertical pour la génération d'air de réfrigération. Les mesures prises pour une fonction de réfrigération avantageuse contribuent à ce qu'au moins l'interstice vertical abrite également au moins un ventilateur (56), notamment en tant que ventilateur radial, pour provoquer la circulation d'un flux d'air à travers les interstices (11.6, 12.4, 13.7) (Fig. 1 ).
