Heater configuration for a melting device with non-uniform thermal load
Abstract:
A variable resistive heater element enables current to flow through a first resistive heater element and a second resistive heater element based on the temperature of the variable resistive heater element. Current flows through the first resistive heater element, and is restricted through the second resistive heater element, when the variable resistive heater element is less than a predetermined temperature. Current flows through the first and second resistive heater elements when the variable resistive heater element is at or greater than a predetermined temperature.
