ARRANGEMENT FOR HEATING LIQUID Russian patent published in 2006 - IPC F24J3/00 

FIELD: the arrangement for heating liquid refers to heating engineering.

SUBSTANCE: arrangement has stator with cylindrical cavity, inlet channels for supplying liquid and outlet channel for conducting liquid and also a rotor installed into the cavity with clearance. The rotor is fulfilled in the shape of an installed on the shaft disc with non through openings located along the circumference down to periphery of its butt-ends. The inlet channels are located on stator butt-ends walls around the rotor shaft on the sides opposite to the disc and are provided with throttling orifices and the outlet channel is located on the stator cylindrical wall and forms with adjacent sites of stator butt-ends walls and with the site of the disc cylindrical surface an outlet collector, on the periphery of stator butt-ends walls non through openings similar to the non through openings on the rotor disc are fulfilled. At that non through openings on the both butt-ends of the disc and on the opposite stator butt-ends walls are fulfilled in the shape of radial rows and a facet or a round-up is fulfilled in each non through opening. Non through openings on the rotor disc and on stator butt-ends walls may be fulfilled in the shape of cylindrical, conical or ball surface.

EFFECT: such fulfillment of the arrangement increases effectiveness of heating liquid due to dense abutment of liquid to butt-ends' surfaces of rotor and stator and increasing of the effect of friction of liquid about the walls.
