Abstract
An electronic device includes a heat source, a heat-absorbing cold point, a thermally insulating material for insulating the heat source from the cold point with a conductivity at a use-temperature of electronic device, that is below a thermal-conductivity threshold, and a thermal bridge having first and second ends connected by pads to the heat source and the cold point, and a thermal switch. The thermal bridge extends between the two ends and switches reversibly between conductive and non-conductive states. It includes material of variable thermal conductivity capable of switching over, in response to an addition of energy, between a conductive phase and a resistive phase, and a control module for causing the thermal switch to switch between the conductive state and the resistive state.
