Title (EN) CRYOGENIC COOLING SYSTEM WITH TEMPERATURE-DEPENDENT THERMAL SHUNT
(FR) SYSTÈME DE REFROIDISSEMENT CRYOGÉNIQUE À DÉRIVATION THERMIQUE DÉPENDANTE DE LA TEMPÉRATURE
Abstract:
(EN) A cryogenic cooling system (10) comprising a cryostat (12), a two-stage cryogenic cold head (24) and at least one thermal connection member (136; 236; 336; 436) that is configured to provide at least a portion of a heat transfer path (138; 238; 338; 438) from the second stage member (30) to the first stage member (26) of the two-stage cryogenic cold head (24). The heat transfer path (138; 238; 338; 438) is arranged outside the cold head (24). A thermal resistance of the provided at least portion of the heat transfer path (138; 238; 338; 438) at the second cryogenic temperature is larger than a thermal resistance of the provided at least portion of the heat transfer path (138; 238; 338; 438) at the first cryogenic temperature.
(FR) L'invention concerne un système de refroidissement cryogénique (10) comprenant un cryostat (12), une tête froide cryogénique à deux étages (24) et au moins un élément de liaison thermique (136; 236; 336; 436) conçu pour fournir au moins une partie d'un circuit de transfert de chaleur (138; 238; 338; 438) de l'élément de second étage (30) à l'élément de premier étage (26) de la tête froide cryogénique à deux étages (24). Le circuit de transfert de chaleur (138; 238; 338; 438) est disposé à l'extérieur de la tête froide (24). Une résistance thermique de ladite partie du circuit de transfert de chaleur (138; 238; 338; 438) à la seconde température cryogénique est plus grande qu'une résistance thermique de ladite partie du circuit de transfert de chaleur (138; 238; 338; 438) à la première température cryogénique.
