Portable liquid fuel vaporizer

A portable vaporizer for heating a liquid phase fuel, the portable vaporizer comprising:

• a reservoir having at least one wall for containing a liquid;
• a heat-conducting fluid within the reservoir;
• a heating core, the heating core extending into the reservoir in the shape of a cylinder having a plurality of spirals such that the heating core is in fluid contact with the heat-conducting fluid, the heating core having an inlet through which the liquid phase fuel will flow and an outlet through which vaporized liquid phase fuel will flow;
• a heating passage, the heating passage being a u-shaped hollow tube having at least one open end and at least partially surrounding the heating core, the heating passage extending at least partially within the reservoir such that at least a portion of an exterior surface of the heating passage is in fluid contact with the heat-conducting fluid;
• a heat source, the heat source communicating with the at least one open end of the heating passage to heat the heating passage and the heat conducting fluid surrounding the heating passage to vaporize the liquid phase fuel within the heating core;
• a first pressure regulator;
• the first pressure regulator fluidly connected upstream of the inlet of the heating core such that the liquid phase fuel will undergo a first pressure drop before entering the heating core, the first pressure drop being within a high pressure range;
• a second pressure regulator, the second pressure regular fluidly connected downstream from the outlet of the heating core and upstream of the heat source such that the vaporized liquid phase fuel will undergo a second pressure drop before entering the heat source source, the second pressure drop being within a low pressure range;
• and
• at least one handle, the at least one handle allowing a single user to transport the portable vaporizer.
