Abstract

The disclosure provides a cryogenic cooling chamber configured for use with an oxygen liquefaction system. The cooling chamber may include an oxygen condensing heat exchanger, a recuperator, a throttle, an evaporator tube, and a housing. The oxygen condensing heat exchanger may have a cylindrical shape. The recuperator may be adjacent the oxygen condensing heat exchanger and may be configured to receive coolant entering the cryogenic chamber. The throttle may be configured to receive the coolant from the recuperator and to throttle the coolant. The evaporator tube may extend around a perimeter of the oxygen condensing heat exchanger and configured to receive the coolant from the throttle and to transfer heat from the oxygen condensing heat exchanger to the coolant in the evaporator tube. The recuperator may configured to transfer heat from the coolant exiting the evaporator tube to the coolant entering the cryogenic chamber. The housing may be configured to house the oxygen condensing heat exchanger, the throttle, the evaporator tube, and the recuperator.
