METHOD AND APPARATUS FOR HEATING LIQUIDS

摘要

A fluid heating apparatus using cavitation 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 heating zone. The inner surface of the housing is configured with a spiral shape and wave form to enhance the heating of the fluid.
