Abstract

Un conteneur transportable (10) de produits à des températures de congélation ou de refroidissement comprend un conteneur structural (12) avec une enveloppe extérieure isolée (14, 15, 16, 17) et une porte d'accès (21). La partie supérieure du conteneur (10) comprend une chicane perforée transversale (25) au-dessus de laquelle sont agencés deux bidons (27, 28) mutuellement espacés qui contiennent un liquide de refroidissement. Un tube (32) d'alimentation en gaz ou en liquide pénètre dans chaque bidon et est en communication avec une soupape marche-arrêt (30, 31). Le tube d'alimentation (32) sert à puiser et à distribuer le liquide de refroidissement, ou à détendre le gaz et la pression à l'intérieur du bidon (27, 28) afin de porter à ébullition le CO2. Lorsque le CO2 atteint son point d'ébullition, le bidon (27, 28), son atttache et la plaque de refroidissement (25) atteignent des températures très basses afin de refroidir la zone de chargement (24). Le gaz est détendu dans des tubulures en cuivre agencées sur la plaque de refroidissement (25).
