INDUCTION HEATING COIL, AND INDUCTION HEATING DEVICE USING SAME

摘要

An induction heating coil according to the present invention is formed by spirally winding an elongate laminated conductor around a coil axis, the elongate laminated conductor including a plurality of conducting layers extending in an elongate direction and a plurality of insulating layers formed between the conducting layers, each of the conducting layers being connected in parallel with one another at both ends of the elongate laminated conductor, and the conducting layers being laminated in a direction perpendicular to the coil axis around which the elongate laminated conductor is wound, wherein the elongate laminated conductor has a width (W) along the direction perpendicular to the coil axis is greater than a height (H) along the direction parallel to the coil axis. This achieves a light and inexpensive induction heating coil which is easy to be manufactured with high dimensional precision while substantially improving the cooling efficiency thereof.
