DEVICE TO HEAT GAS FLOW BY WIRE ELECTIC HEATER Russian patent published in 2010 - IPC H05B3/26 

FIELD: electric engineering.

SUBSTANCE: invention relates to electrical heaters and can be used in, for example gas flow heaters incorporates with anaesthesia apparatuses, inhalator devices etc. Proposed device comprises carcass made from heat resistant dielectric material and representing a base with support elements and spiral resistive element. It differs from known designs in that said resistive element represents several sections made up of coils connected in parallel and having various length of conductors. Said length is calculated from mathematical relationship. Note here that hear conductor is coiled on aforesaid carcass made from axial tube, spikes are fitted on the ends of said tube. Porcelain tubes are laid between said spikes fastened together by rods passed there through. Variation in conductor length in every other coil of the heater increases specific power on spiral coils. Heater structure makes rigid impact- and vibration-proof carcass.

EFFECT: expanded performances.
