  • Vaporizer with foil heat exchanger
    Patent number: 8490627
    Abstract: This invention vaporizes a botanical substance for inhalation using a combustion generated heat source. A substantially planar non-porous heat exchanger transfers heat to the inhalation air and keeps combustion byproducts separated from the inhalation air. In use, air is drawn past the heat exchanger and then through a reservoir holding the botanical substance, vaporizing any volatiles in the substance. The heat exchanger assembly can be magnetically attached to the pipe assembly.
