Abstract

L'invention concerne un appareil réfrigérant, notamment un appareil réfrigérant ménager, comprenant un corps qui délimite une chambre réfrigérante (5), est rempli d'une mousse thermo-isolante et présente un cadre frontal (13) entourant une ouverture d'introduction (3) pour les produits à réfrigérer et coopérant avec une porte d'appareil (1). Sur le côté du cadre frontal opposé à la porte d'appareil (1) est ménagé un canal de passage (32), notamment dépourvu de mousse, à travers lequel est guidée une conduite chauffante (33). Selon l'invention, la conduite chauffante (33) guidée à travers le canal de passage (32) sans mousse est appliquée avec une force de compression (F) prédéfinie contre le cadre frontal (13) de façon à conduire la chaleur.
