ROTOR-TYPE CIRCULATION HEATER

摘要

The invention relates to heat engineering and can be used for heating a liquid for providing heating and hot water supply. A rotor-type circulation heater comprises an electric motor, a hermetically sealed vessel containing a liquid, and a stationary housing with a cylindrical cavity which is connected to the hermetically sealed vessel, said cavity containing a rotor in the form of a disc with working surfaces, which is mounted on the shaft of the electric motor, wherein elements for generating a cavitation process in the working volume of the liquid are disposed on working surfaces of the disc and of the housing. Each element for generating a cavitation process is in the form of a nozzle which is disposed tangentially to the axis of rotation of the rotor and is mounted either on a working surface of the rotor at a distance Ai or on a working inside surface of the housing at a distance A'i from the axis of the rotor, wherein the values Ai and A'i are determined by given relations.
