US 2003/0205228 A1 · Dual capillary fluid vaporizing device

Abstract

A fluid vaporizing device useful for vaporizing fluid into an aerosol and includes first and second capillary tubes connected electrically in series by providing separate electrodes at the inlet ends of each capillary tube, and connecting the outlet ends of the capillary tubes by an electrical connection that connects the outlet ends both electrically and thermally. The capillary tubes are heated by the flow of electricity therethrough, and liquid flowing through the tubes is vaporized. The outlet ends of the capillary tubes are easily maintained at a temperature for optimizing aerosol generation since there is minimal heat loss through the connection connecting the outlet ends.
