ABSTRACT:
The present invention deals with a new and efficient heater for fluids in general, wherein the heat is generated by means of electromagnetic induction directly on the duct where the fluid circulates. The heater as described may be constructed according to two preferred embodiments which generally consist in disposing a magnetic core having a mono, a bi, a tri or a polyphase primary winding and on which is arranged a series of straight tubes disposed transversely or longitudinally in respect to the magnetic core. The tubes are soldered at their ends to compartments which act as reservoirs for the fluids to be heated, and, for the fact of being conductive as the tubes, they function as a secondary on which a short-circuit current is induced by the primary, thus causing the heating of the tubes.
