Abstract
A heating system of the present disclosure includes: a heating element configured to generate heat; a thermoelectric device disposed adjacent to the heating element; and a switching device electrically connected to the thermoelectric device and configured to maintain a temperature of the heating element within a set temperature range by switching current that is supplied to the thermoelectric device based on the temperature of the heating element.
Claims13
A heating system comprising:
- a heating element configured to generate heat;
- a thermoelectric device disposed adjacent to the heating element;
- and
- a switching device electrically connected to the thermoelectric device and configured to maintain a temperature of the heating element within a set temperature range by switching a current that is supplied to the thermoelectric device based on the temperature of the heating element;
- and
- a thermal buffer disposed between the heating element and the switching device,
- wherein the switching device has a metal-insulator transition (MIT),
- wherein the switching device has a phase transition temperature lower than the set temperature, and
- wherein the thermal buffer is configured to allow the phase transition to occur at a temperature that is lower than the set temperature by buffering heat during its transfer from the heating element to the switching device.
