Abstract
A method and apparatus for temperature control of an article is provided that utilizes both the resistive heat and inductive heat generation from a heater coil.
Claims13
A method for heating an article comprising the steps of:
- providing a coiled electrical conductor in thermal and magnetic communication with said article;
- closing a magnetic circuit around said coiled electrical conductor;
- supplying power to said coiled electrical conductor to produce inductive heat in said article and resistive heat in said coiled electrical conductor;
- and
- directly transferring substantially all the resistive heat generated in said coiled electrical conductor to said article.
