ABSTRACT:
This invention pertains to an electromagnetic induction fluid heating apparatus equipped with a heating element constructed from a conductive material installed in a fluid flow passage, a coil installed around this heating element, and a high frequency electrical current generator for this coil. In particular, this heating element is a layered component that allows electrical conduction between metallic plates. This heating element is formed so that electrical current vortices occur throughout this layered component. By forming a fluid flow passage that allows mixing within this layered component, the electrical power efficiency becomes 100%. Moreover, this high frequency electrical current generator is an invertor that uses semiconductor power devices such as SIT, B-SIT, MOSFET, IGRT, and MCT, etc. When the preferred PWM system (Pulse Width Modulation) is used, the heating efficiency (affected by the efficiency of the invertor, etc. matched with this layered component) exceeds 90%.
