Induction heating apparatus for a fluid.

摘要

The invention relates to a device for heating by induction of an electrically conductive fluid (10). According to the invention, the said device comprises: - a closed magnetic circuit (100), - at least one inductor consisting of a winding (200), arranged around the magnetic circuit and supplied with an alternating electric voltage, in such a way that the said inductor generates a magnetic flux in the magnetic circuit, - at least one chamber (300), made of insulating material, containing the fluid to be heated and surrounding each inductor, - a medium-frequency converter supplying each inductor, and - means for causing the converter to resonate. Application to heating fluids of corrosive nature having a conductivity greater than 1 siemens/metre.
