Definitions
- the present invention is also a cooling method in a regenerative refrigerator that repeatedly compresses and expands a refrigerant gas to cool the cooling stage to an extremely low temperature, and the FRP has a thickness of 0.1 mm to 1 mm on the cooling stage.
- a thin plate made of metal is attached and cooled while controlling the temperature of conduction from the cooling stage. By doing so, it is possible to set the cooling temperature with high accuracy while suppressing the temperature oscillation of the cooling stage.
- the thickness of the FRP thin plate 62 is set to 0.78 mm, and the dispersion value ⁇ (solid line 1) and ⁇ / T (dotted line 2) of the temperature of the sample 54 from 4.2K to 300K.
- the measurement results are shown. It can be seen that ⁇ and ⁇ / T are small in the temperature range of 4.2 K to 300 K, and the cooling temperature is stable. If the thickness of the FRP thin plates 61 and 62 exceeds 1 mm, the heat transfer loss increases and the cooling effect is reduced. Further, the heat transfer loss decreases as the thickness becomes thinner. However, if the thickness becomes too thin, the effect of suppressing the temperature vibration is reduced. Therefore, it is desirable to set the thickness to 0.1 mm or more.

Abstract
L'invention concerne un cryorefroidisseur du type stockage de froid qui permet de produire des températures de refroidissement stables au moyen d'une structure simple. Le cryorefroidisseur du type stockage de froid refroidit l'étage de refroidissement (32) à des températures cryogéniques par la compression et la dilatation répétées d'un gaz frigorigène, et comporte une plaque mince (61) faite de FRP, qui présente une épaisseur de 0,1 mm à 1 mm et est fixée à l'étage de refroidissement (32). La plaque mince (61) de FRP, dont l'épaisseur est comprise dans la plage mentionnée, permet d'inhiber des fluctuations de la température de l'étage de refroidissement (32). Si l'épaisseur de la plaque mince (61) de FRP est supérieure à 1 mm, la perte de transfert de chaleur augmente et l'effet de refroidissement diminue. Si l'épaisseur de la plaque mince est inférieure à 0,1 mm, l'effet d'inhibition des fluctuations de température est faible. Dans ce cryorefroidisseur du type stockage de froid, on peut réduire les fluctuations de température en fixant simplement la plaque mince (61) de FRP, ce qui permet de stabiliser la température de refroidissement du cryorefroidisseur du type stockage de froid. Par conséquent, l'invention permet de refroidir des objets refroidis (70) qui nécessitent d'être maintenus à une température de refroidissement constante, et de régler précisément la température de ceux-ci, ce qui élargit le champ d'applications de ce cryorefroidisseur du type stockage de froid.
