Abstract
A portable vaporizer for heating a liquid-phase fuel. The vaporizer comprising a reservoir having a least one wall for containing a heat-conducting fluid within the reservoir. A heating tube extending into the reservoir such that the heating tube is in fluid contact with the heat-conducting fluid. The heating core has and inlet through which the liquid-phase fuel will flow and an outlet through which the vaporized liquid-phase fuel will flow. A heating core comprising an electric heating element placed within the reservoir to heat the heat-conducting fluid and vaporize the liquid-phase fuel passing through the heating tube.
Claims16
A vaporizer for heating a liquid-phase fuel, the vaporizer comprising:
- a reservoir having a least one wall for containing a heat-conducting fluid;
- a heating tube, the heating tube having an inlet end through which liquid-phase fuel will flow and an outlet end through which gaseous fuel will flow;
- the heating tube being thin-walled such that the exterior surface of the heating tube is in contact with the heat-conducting fluid and an interior surface of the heating tube is in partial contact with the liquid-phase fuel before being vaporized;
- at least one electric heating element within the reservoir, the at least one electric heating element being in contact with the heat-conducting fluid to increase the temperature of the heat-conducting fluid to a predetermined temperature, the predetermined temperature being such that the liquid phase fuel entering the heating tube will at least partially vaporize before exiting the heating tube;
- a temperature gauge, the temperature gauge having a first portion in contact with the heat-conducting fluid and a second portion to indicate the temperature of the heat-conducting fluid in contact with the first portion;
- a controller, the controller operatively connected to the at least one electric heating element to alter the heat output of the at least one electric heating element;
- a first flexible hose;
- a pressure regulator;
- and
- a one-way valve fluidly, wherein the first flexible hose has a first end fluidly connected to the inlet end of the heating tube and a second end fluidly connected to an outlet of the pressure regulator, the pressure regulator further having an inlet fluidly connected to an outlet of the one way valve which has an inlet connected to a tank containing the pressurized liquid-phase fuel, the one-way valve permitting the liquid-phase fuel to flow in a direction from the tank to the heating tube only.

A portable vaporizer for heating a liquid-phase fuel, the portable vaporizer comprising:
- a reservoir having a least one wall for containing a heat-conducting fluid;
- a handle fixed to the at least one wall for transporting the portable vaporizer;
- a heating tube, the heating tube having an inlet end through which the liquid-phase fuel will flow and an outlet end through which gaseous fuel will flow, the heating tube being thin-walled such that the exterior surface of the heating tube is in contact with the heat-conducting fluid and an interior surface of the heating tube is in contact with the liquid-phase fuel before being vaporized;
- a first flexible hose fluidly connected to the inlet end of the heating tube;
- a first toolless connector fluidly connecting the first flexible hose to the inlet end of the heating tube;
- a second flexible hose fluidly connected to the outlet end of the heating tube;
- a second toolless connector fluidly connecting the second flexible hose to the second end of the heating tube, the first and second toolless connectors enabling quick connecting/disconnecting between the first and second flexible hoses and the heating tube;
- at least one electric heating element within the reservoir, the at least one electric heating element being in contact with the heat-conducting fluid to increase the temperature of the heat-conducting fluid to a predetermined temperature, the predetermined temperature being such that the liquid phase fuel entering the heating tube will at least partially vaporize before exiting the heating tube;
- a flexible power cord, the flexible power cord having a first end, a second end and an electric plug, the first end of the flexible power cord being connected to the at least one electric heating element, the second end of the flexible power cord connected to the electric plug such that the electric plug can be selectively and toolessly connected to a portable power source;
- wherein the first and second toolless connectors and the plug renders the portable vaporizer transportable without the power source and the liquid-phased fuel.
