Abstract
A fluid cavitation apparatus includes a housing, an external rotor with cavitation bores in an outer surface thereof, and a motor for rotating the external rotor. An inner surface of the housing is spaced from the outer surface of the external rotor to create a fluid cavitation zone. The inner surface of the housing is configured with a spiral shape and tunnel zone to enhance the thermal transfer characterisitics of the fluid for heating, cooling, and purification. A control system to facilitate proper motor speed, and fluid behavior to enhance the cavitation process.
Claims16
An apparatus for heating a fluid using cavitation comprising:
- a housing having an inlet for fluid to be heated and an outlet to discharge the heated fluid from the housing;
- an external rotor adapted to be fixed on a motor shaft extending in a axial direction, the external rotor contained in the housing and adapted to rotate within the housing, the external rotor having a plurality of cavitation bores arranged in an outer surface thereof and the external rotor arranged within the housing to form a fluid heating zone between the outer surface of the external rotor and an inner surface of the housing that faces the outer surface of the external rotor, the inner surface of the housing extending in the axial direction and a housing circumferential direction,
- wherein the inner surface of the housing facing the bore-containing outer surface of the external rotor has a plurality of first funnel zones extending along the inner surface of the housing and in the housing circumferential direction, the plurality of first funnel zones laterally spaced apart from each other in the axial direction, each first funnel zone terminating in a first discharge zone, each first funnel zone including a first ramp, each first discharge zone offset in the housing circumferential direction from an adjacent first discharge zone, fluid entering the housing being heated by interaction with the first funnel zones and first ramps, bores in the external rotor, and external rotor rotation.
