EVAPORATOR FOR CRYOGENIC LIQUID Russian patent published in 2004 - IPC

FIELD: cooling equipment, particularly evaporators.

SUBSTANCE: evaporator comprises body with inlet and outlet means for coolant including chambers for liquid and gaseous coolant, heat exchanger and bulk filling. Heat exchanger includes pipe bundle. Heat exchanger tube space is filled with bulk filler. Outlet means includes central tube provided with ejector. Receiving ejector chamber communicates with tube space, nozzle communicates with chamber for gaseous coolant. Inlet means comprises connection pipe. Connection pipe and outer wall of central pipe define annular cavity communicating with chamber for liquid coolant. Evaporator has receiving chamber for worked out coolant communicating with receiving chamber of ejector through tube space. Ejector nozzle may be displaced in vertical direction.

EFFECT: increased operational efficiency due to reduced energy consumption for liquid evaporation and possibility of evaporated liquid flow rate and temperature regulation.
