CRYOGENIC LIQUID EVAPORATOR Russian patent published in 2013 - IPC F17C9/02 F25B39/02 

FIELD: machine building.

SUBSTANCE: cryogenic liquid evaporator includes a housing with cooling agent inlet and outlet chambers, heat exchange elements containing a liquid cooling agent chamber and a central tube equipped with an ejector. Cooling agent inlet and outlet chambers are divided with a partition wall with a hole, heat exchange elements are installed in the partition wall and interconnected with the central tube; the central tube is installed into the hole made in the partition wall with a gap, and the ejector has an insert that controls gaseous cooling agent from liquid cooling agent chambers. Cryogenic liquid evaporator is equipped with a recuperator. Evaporator allows increasing cooling agent use efficiency due to repeated use of cooling agent and arrangement of two-stepped cooling of working substance.

EFFECT: absence of any additional heat source for evaporation of liquid cooling agent and absence in the design of massive heat exchange head pieces additionally increases evaporator operating efficiency and reduces hydraulic resistance of an evaporator.
