AIR HEATER Russian patent published in 2023 - IPC F24H3/00 F24H3/06 

FIELD: air heaters.

SUBSTANCE: claimed air heater is related to heating residential, commercial and industrial premises. The air heater contains an insulated outer insulating casing, an internal cartridge, metal connection terminals, an insulating composition, and a temperature cut-off relay. The internal cartridge consists of internal and external heat exchange elements in contact with the heated air flow and separated by a ceramic filler. The cartridge is installed with a gap relative to the outer housing. Heating elements are located inside the filler adjacent to the internal heat exchange element.

EFFECT: when using the invention, the operating time of heating elements is reduced, heat transfer efficiency is increased, which reduces electricity consumption, and ensures safe operation of the product in a wide range of operating temperatures from minus 60°C to plus 200°C, while providing a heating delta of air masses of 50°C, and also provides the ability to scale the heater power by increasing the area of the heat exchanger, the number and power of heating elements.
