COOL-BOX COMPRISING A REFRIGERATOR ATTACHMENT, SAID COOL-BOX OPERATING WITHOUT POWER OR ICE

摘要

The invention relates to a cool-box comprising a refrigerator attachment, said cool-box operating without power or ice. The cool-box is formed by a preferably plastic casing to which a metal capsule is anchored that contains a cryogenic liquid, such as liquid nitrogen or liquid oxygen, acting as a liquid coolant. The capsule is removably attached to the casing of the cool-box using anchors, and the capsule is equipped with a valve for the injection-refilling of liquid coolant and an exhaust relief valve. The cool-box also comprises an insulating lid and connecting pipes made from thermally conductive sheet metal, which join the capsule to the interior of the casing, thereby transferring cold.
