ABSTRACT:
A method and apparatus for cooling a heat load in which a pressure vessel is provided to contain a cryogen as a saturated liquid and saturated vapor separated by liquid-vapor interface. The pressure vessel has an inlet adapted to receive a subcooled liquid cryogen and thereby convert it to a saturated liquid through contact with the saturated vapor. A heated overflow tube projects into the pressure vessel and is level, at one end, with the liquid-vapor interface so that any increase in the saturated liquid overflows into overflow tube and is vaporized to form the saturated vapor. The heat transfer and the reintroduction of the vaporized liquid can be effected through forced circulation provided by an ejector. Preferably the pressure vessel is provided with two outlets for discharging the saturated cryogen as saturated liquid or vapor. One or more ejectors having high pressure inlet(s) in communication with the two outlets of the pressure vessel are provided for drawing the heat transfer fluid, after having cooled the heat load, into a heat transfer relationship with the overflowed saturated liquid and then into mixture(s) with the saturated liquid or saturated vapor, or both and for discharging the same out of a high pressure outlet of the ejector to the heat load.
