Definitions

  • the invention relates to a device for vaporizing and / or atomizing of liquid.
  • a device according to the preamble of claim 1 is known from EP-A-726 550.
  • the invention is therefore based on the object of an evaporator at the beginning mentioned type, which is capable of self-sufficient work, a large Amount of liquid to evaporate or nebulize, the smaller one Design allows and is easy and inexpensive to manufacture.
  • the released energy is in a density that no electrical Radiators can only be produced approximately:
  • the Termite mixture as a heating mixture to white hot iron as Heat source in the radiator housing (12) in front of the fog cartridge, i.e. one Temperature where every other radiator has long since ceased to function would have. This can significantly increase both the heating output and the outer dimensions can be significantly reduced.
  • the main advantage of the invention is the self-sufficient operation of the Device that allows independent of external energy supply or to be ready for work at all times.
  • the fog cartridge is included maintenance-free and can be used for up to 20 years from the date of manufacture. If the heating mixture is selected appropriately, the cartridge is not subject to this Explosives Act, it can even be stored at temperatures up to 300 ° C be without sacrificing reliability.
  • the one to be evaporated Liquid through itself after lighting the pyrotechnic Heating mixture quickly heats up the metal core with or without cooling fins and at least partially evaporated. This steam creates one in the housing Vapor pressure, which is the heated or at least partially evaporated liquid drives through an air pipe opening into the pipe system or pipe-like system. In this takes place a complete evaporation, the dry so produced Superheated steam emerges from the housing under increased pressure. There he will cooled and condensed after a short time to the finest droplets in their Result in the very stable fog.
  • Another advantage of the invention is the fact that by Housing solution no regulation or other assemblies for generating fog must be used, so an extremely simple and small cartridge is possible.
