Abstract
A novel device for controlling the radiative transfer of heat is proposed. An Active Radiator tile (ART) is composed of two parallel plates separated by small thermally insulating posts. In the rest state, the ART presents a large thermal resistance. Application of a suitable potential across the plates causes one plate to deflect into direct contact with other plate, allowing a large conductive heat flow. Thus the ART device acts as a thermal valve. We report the modelling of the mechanical and thermal properties of the device, and progress towards the construction of a laboratory prototype.
