FIELD: heating engineering.
SUBSTANCE: fluid heater can be used in devices for producing heat without burning fuel. Heater has cylindrical stator and rotor inserted into stator. Rotor is formed by cylinder having metal rim spat onto the cylinder. Rim has a number of radial hollows at its external surface. Hollows should be made in form of through holes. Surface of cylinder acts a role of bottoms of radial hollows in rotor. Surface of the rim should have shape of a cone.
EFFECT: improved stability of heating; improved efficiency; reduced maintenance charges.
