Abstract

La présente invention concerne un dispositif de réfrigération et de congélation, comprenant un corps d'armoire et une partie de communication. Le corps d'armoire comprend un premier revêtement et un second revêtement, qui ont des ouvertures dans la même direction. La partie de communication est conçue pour faire communiquer le premier revêtement avec le second revêtement et pour qu'il y ait un conduit d'air de communication formé sur celui-ci, de telle sorte que l'air froid s'écoule entre le premier revêtement et le second revêtement. La partie de communication est conçue pour être en communication avec le premier revêtement sur la paroi latérale du premier revêtement à proximité du second revêtement, et pour être en communication avec le second revêtement sur la paroi latérale du second revêtement à proximité du premier revêtement. Le dispositif de réfrigération et de congélation de la présente invention simplifie non seulement la structure et réduit les coûts de production, mais peut également réduire les matériaux moussants parce qu'il assure des performances d'isolation thermique, ce qui permet d'augmenter le volume de stockage efficace du dispositif de réfrigération et de congélation.
