Abstract:
1. A fluid heating device comprising a housing having an internal chamber and a fluid inlet and a fluid outlet in fluid communication with said internal chamber, said fluid inlet and said fluid outlet each opening exteriorily of said housing; a rotor disposed centrally in said main chamber and mounted for rotation within said chamber about an axis of rotation, said chamber being dimensioned relative to said axis such that the maximum transverse radial distance is greater than the maximum longitudinal distance; said rotor having a plurality of openings formed on at least a face thereof confronting fluid entering said chamber, wherein rotation of said rotor causes said plurality of openings to impart heat-generating cavitation to a fluid entering said chamber, and wherein said chamber is a generally hemi-spherical volume and said rotor is in the form of a hemi-spherical element, said rotor in spaced relation to said housing to provide a passage for fluid to travel from said inlet towards said outlet.
