ABSTRACT:
A device for temporarily overcooling a detector (1) cooled permanently in a space by means of a first cooler (5).
According to the invention, a second cooler (6) is temporarily made operative to produce the required overcooling without causing heat exchange with the outside. For this purpose, the thermal energy dissipated by the cooler (6) is absorbed by the passage from solid to liquid of a material changing in phase (7) (water or tetradecane) arranged between the first and second coolers.
