ABSTRACT:
A compact liquefied vaporizer for controlled vaporization of liquefied gas. The vaporizer includes a vertically oriented, cylindrical, hollow pressure vessel having a liquefied gas inlet near an open lower end and a gas vapor outlet near closed upper end, and an elongated, one-piece, heat-conductive aluminimum core mounted within the pressure vessel and occupying a substantial portion of the interior volume of the pressure vessel. The core is threaded to provide a closure for the lower end of the pressure vessel and has multiple electrical resistance elements extending longitudinally therein and cast in-situ within the core to provide intimate contact to the core with the exterior of the heating elements. The vaporizer has a thermocouple position within a central bore in the core, and electronic controls connected to the electric resistance heating elements and the thermocouple for regulating the supply of power to the heating elements.
