ELECTROMAGNETIC INDUCTION-HEATING DEVICE

This electromagnetic induction-heating device for heating a fluid has a cylindrical insulation member (10) letting the fluid flow through the interior thereof, the cylindrical insulation member (10) being enclosed by an outer shell member (2, 3), except for an outlet-side opening (10e) serving as an outlet for the fluid. A flow inlet (3a) letting an inflow of the fluid to the interior of the outershell member (2, 3) is provided on the outer shell member (2, 3), and is closer to the outlet-side opening (10e) than to an inlet-side opening (10i) serving as a fluid inlet for the cylindrical insulation member (10). An electromagnetic induction coil (25) is wound around the outer periphery of the cylindrical insulation member (10). A heat-generating magnetic body (20) is disposed so as to forma flow path inside the cylindrical insulation member (10). In this manner, a compact electromagnetic induction-heating device is provided having improved fluid-heating efficiency, and capable of heating a high-pressure fluid.
