ABSTRACT:
A vapor chamber cooking device is disclosed wherein a capillary wick is disposed along the bottom surface of a sealed vapor chamber, the top wall of which provides a cooking surface. A plurality of internal structural support members having vapor pressure equilization holes are disposed between the wick and the upper surface of the chamber and secured to the upper chamber surface. A quantity of volatile working fluid is disposed in the chamber sufficient to saturate the wick when in a liquid state. An arrangement is provided for heating the chamber to vaporize working fluid contained therein, and a feedback control arrangement responsive to the vapor pressure within the chamber controls the heating arrangement to maintain the chamber vapor pressure within a predetermined range. Additional arrangements may be provided to respond to predetermined conditions of overpressure within the chamber to relieve the overpressure conditions.
