Abstract
Vaporizers having a thermal wick are provided. A thermal wick may include a combination of an electrically insulating porous wicking material surrounding, enclosing, covering or embedded within a thermally conductive material. The thermally conductive material has a thermal conductance greater than that of the porous wicking material. The thermal wick reduces the viscosity of vaporizable material by transferring heat throughout the wick and warming the vaporizable material and providing a high void volume. The thermal wick allows for substantially higher total particulate masses of vaporizable material than traditional wicks.
