INDUCTION HEATING HEAD |
摘要 |
<p>An induction heating system includes a power source and an induction head. The converter output is at a voltage that is not greater than the voltage applied to the coil. The induction head includes a housing that houses a conductive coil disposed to induce heat in a workpiece and the coil is wound to be tuned to the output power. The coil is wound in a stacked spiral pattern with at least two turns in each layer. A flux concentrator is disposed about the coil with a potting compound around the concentrator and coil. Spacers maintain a desired separation between the head and the workpiece. The coil is a tube carrying a coolant. The head includes a wear surface that prevents contact of the coil and the workpiece, and a thermal insulator between the coil and wear surface. A non-contact temperature sensor is mounted to the housing.</p> |
