FLUID MEDIUM INDUCTION HEATER Russian patent published in 2009 - IPC H05B6/00 

FIELD: electrical engineering.

SUBSTANCE: proposed heater comprises three-phase transformer with ferromagnetic core. Transformer primary is connected to AC circuit and its secondary that makes heat exchanger for fluid medium. Aforesaid heat exchanger consists of three chambers, each representing different-diametre cylinder arranged concentrically one into the other and plugged on top and bottom with the help of face plus to form tight hollow chamber for fluid medium to be heated therein and to house cores with primary. Pipeline feeding fluid medium into aforesaid chambers is arranged at heater bottom. Two branch pipes to feed fluid medium into first and second chambers are connected to pipeline parallel to each other. End of pipeline feeding fluid medium is connected directly to third chamber. Fluid medium outlet pipeline is arranged on heater top. End of pipeline discharging fluid medium is connected to either first or third chambers. Two other branch pipes to discharge fluid medium are connected to pipeline parallel to each other. Fluid medium branch pipes and pipeline can be arranged at cylinder chamber bottom.

EFFECT: higher efficiency.
