Abstract

Un réfrigérateur de type à refroidissement direct comprend une porte, un boîtier extérieur (3) et un matériau thermo-isolant (4). La porte est ménagée sur un côté du boîtier extérieur (3) et peut avoir la forme d'une porte simple, double, triple ou supérieure. La porte et le boîtier extérieur (3) sont dotés d'un matériau isolant (4) et de cordes d'étanchéité. Une vessie interne (6) et une couche d'air intermédiaire (7) sont prévues dans le boîtier extérieur (3). Une tubulure d'admission (8) d'air de refroidissement communiquant avec l'extérieur est connectée avec l'un des côtés du boîtier extérieur (3). Un ensemble de petits ventilateurs soufflants (20) peut être utilisé à l'extérieur pour faciliter la réfrigération. Le réfrigérateur de type à refroidissement direct n'a pas besoin d'un compresseur, d'un condenseur ou d'autres composants de réfrigération.
