<p>The invention relates to a cryogenic refrigerator and, more particularly, to a thermal link element disposed between the sensor of the refrigerator and the inner casing of the cryostat. The invention resides principally in the fact that the thermal link element (12), which is an element of revolution, has a lateral wall having a groove (16) in which an elastic ring (17) is housed. It is by this ring that the thermal link between the sensor and the cylindrical wall (9) of the internal casing (8) of the cryostat (6) is carried out. The invention is applicable to cryogenic refrigerators for cooling infrared detectors. <IMAGE></p> |
