Abstract

Le dispositif de commande (86) d’une boîte de refroidissement est disposé de manière à ce que lorsque la température (Th) de la tête chaude d’un congélateur de Stirling (30) dépasse une température de référence (Th1), il augmente au maximum la vitesse d’un ventilateur de rayonnement thermique (53) et le débit d’une pompe de circulation (61) et réduit au minimum le débit du congélateur de Stirling (30). Si la température (Th) de la tête chaude dépasse une température de seuil (Th2) même après cette commande, le congélateur de Stirling (30) est arrêté. Il est ainsi possible d’augmenter la fiabilité de la boîte de refroidissement par rapport au cas dans lequel le congélateur de Stirling (30) est arrêté juste après que la température (Th) de la tête chaude ait dépassé la température de seuil (Th2).
