Abstract
Evaporation device with an expansion component which may be a capillary or series of orifices of increasing cross-sectional area, an insulated housing, a coil within the housing for conducting a material to be cooled by the evaporation of liquid refrigerant, a separation component for receiving refrigerant from the expansion component and separating liquid refrigerant from gaseous refrigerant and directing liquid refrigerant over the coil, an outlet for receiving gaseous refrigerant from the separation component and from over the coil, and a storage element within the housing beneath the coil for collecting liquid refrigerant not evaporated by passage over the coil. Preferred evaporation devices also include a precooler and a liquid refrigerant outlet which permits controlled liquid refrigerant outflow.
