Abstract
A passive thermal switch device, for regulating a temperature of a thermal component configured to generate heat, includes a first plate and a second plate. The first plate is provided on the thermal component. The first plate includes a thermal switch material that switches from an antiferromagnetic state to a ferromagnetic state upon exceeding a state transition temperature. The second plate includes a permanent magnet. The second plate is moveable between a thermal insulator position and a thermal conductor position based on a temperature of the thermal switch material. In the thermal insulator position, the second plate is spaced apart from the first plate. In the thermal conductor position, the second plate is in contact with the first plate.
