  • the most prominent applications for corresponding evaporator systems are electronic cigarettes and preferably portable inhalers for medical applications.
  • the systems known today are mostly based on the fact that a composition stored in a storage tank, which is regularly referred to as liquid/liquid, is vaporized by a more or less controlled supply of thermal energy from a heating element, e.g. a filament, so that the user can can inhale fumes.
