Induction heating is very high efficiency and safety electrical heating method. The effect of induction heating relies on the magnitude of heating frequency. In low-frequency induction heating, core part of pan's bottom generates heat because of skin effect. It is different from surface heating of high-frequency, and enables near-uniform heating. Induction heating is direct heating, so it mainly has effect of conduction. So part of pan except heating part is not heating very much. Therefore it is very important to design and plan for pan and induction heater to gain the maximum effects. In this study, by numerical analysis of thermal behavior of water in various structures and materials of pans, appropriate condition of low-frequency induction heating was led.
