HEATING DEVICE FOR FLUID MEDIUM Russian patent published in 2008 - IPC F24J3/00 

FIELD: thermotechnics.

SUBSTANCE: device for heating of fluid medium refers to thermotechnics and can be used for heat- and hot water supply. There is a device for heating of fluid medium containing a fixed body with a cylindrical cavity and situated in it with a gap cylindrical rotor rigidly fixed on the axle with the possibility of rotation and with a number of irregularities or holes on the cylindrical surface. In the fixed body there is a second cavity in contact with the first one that similarly to the installed rotor contains the second rotor on the second axle, at this the rotors are installed with the possibility of contrarotating from independent drive motors, besides, on the cylindrical surface of each rotor there are rows of closed holes and rectangular slots, which smaller side coicides with the rotor's radius, the holes are made through with an exit to the end surfaces of the rotor, the outlet port is made coaxially with the taper hole joining cylindrical cavities and is placed in the centre of the body.

EFFECT: increase of efficiency with simultaneous increasing spending of fluid medium.
