Abstract

A method and apparatus for cooling a heat load in which a pressure vessel (16) is provided to contain a cryogen as a saturated liquid (18) and saturated vapour (20) separated by liquid-vapour interface (22). The pressure vessel (16) has an inlet (24) adapted to receive a subcooled liquid cryogen and thereby convert it to a saturated liquid (18) through contact with the saturated vapour (20). A heated overflow tube (26) projects into the pressure vessel (16) and is level, at one end, with the liquid-vapour interface (22) so that any increase in the saturated liquid overflows into overflow tube (26) and is vaporised to form the saturated vapour (20). The heat transfer and the re-introduction of the vaporised liquid can be effected through forced circulation provided by an ejector (32 or 34). Preferably the pressure vessel (16) is provided with two outlets (28,30) for discharging the saturated cryogen as saturated liquid or vapour. One or more ejectors (32 or 34) having high pressure inlet(s) (42 or 46) in communication with the two outlets (28,30) of the pressure vessel (16) 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 vapour, or both and for discharging the same out of a high pressure outlet of the ejector to the heat load. <IMAGE>
