CYLINDRICAL VORTEX COOLER Russian patent published in 2017 - IPC F25B19/02 

FIELD: heat exchange.

SUBSTANCE: invention relates to heat exchangers and can be used for cooling and supercooling cryogenic liquids. In compliance with the first version a cylindrical vortex cooler is a cryogenic vessel with a shell arranged on top with branch pipes for inlet and outlet of the cooled liquid, a vapour drain branch pipe, herewith on the outer surface of the vessel there is a heat exchanger, and inside the vessel there is a coolant feed tube, onto which there is a confuser providing centrifugal circulation of the cooled liquid, and at the joint with the returned liquid there is an injector. In compliance with the second version a cylindrical vortex cooler is a cryogenic vessel with a shell arranged on top with branch pipes for inlet and outlet of the cooled liquid, a vapour drain branch pipe, herewith inside the vessel there is a cooled liquid feed tube, onto which there is a confuser providing centrifugal circulation of the cooled liquid, and at the outlet of the non-evaporated liquid there is a diffuser providing filling pressure.

EFFECT: invention is aimed at increased depth of cooling and reduced dimensions.
