Title (EN) A FAULT-TOLERANT CRYOGENICALLY COOLED SYSTEM
(FR) SYSTÈME À REFROIDISSEMENT CRYOGÉNIQUE TOLÉRANT AUX DÉFAILLANCES
Abstract:
(EN) A fault-tolerant cryogenically cooled system comprising: - an outer vacuum chamber (14) defining a vacuum region in its interior volume; - a cryogenic refrigerator (17); - equipment to be cooled, housed within the vacuum region; - a free volume delimited within the vacuum region and containing a cryogen (46); - a cold plate (40) exposed to the free volume and thermally linked to the equipment to be cooled; - a heat exchanger thermally linked to a coldest stage (26) of the refrigerator and exposed to the free volume; - a cryogen buffer vessel (30) delimiting a buffer volume (34); and - a passage (32) linking the buffer volume (34) with the free volume.
(FR) L'invention concerne un système à refroidissement cryogénique tolérant aux défaillances. Ce système comprend: -une chambre à vide externe (14) définissant une région à vide dans son volume intérieur; -un réfrigérateur cryogénique (17); -un équipement à refroidir, logé à l'intérieur de la région à vide; -un volume gazeux délimité à l'intérieur de la région à vide et contenant un cryogène (46); -une plaque froide (40) exposé au volume gazeux et thermiquement relié à l'équipement à refroidir; -un échangeur de chaleur relié thermiquement à un étage le plus froid (26) du réfrigérateur et exposé au volume gazeux; -un récipient tampon de cryogène (30) délimitant un volume tampon (34); et -un passage (32) reliant le volume tampon (34) au volume gazeux.
