Cryogenic Cooling Device

Abstract

The present invention relates to a cryo temperature cooling device ( 1 )comprising 5 a tank ( 2 ), being filled up at least in part with a coolant ( 3 ), and a heat conducting element ( 4 ), whereas the heat conducting element ( 4 ) can be brought into thermal contact with the coolant ( 3 ), so that the coolant has a phase transition occurring below a temperature of −100° C., so that the cryogenic cooling device more or less consumes no coolant during operation.
