Beschreibung
Zusammenfassung:An Active Radiat Tile [1] (ART) thermal valve has been fabricated usin StIicon micromachining. Intended for orbital satellite heat control applications, the operational principle f the ART is to control heat flow between two thermall isolated surfaces by bringing the surfaces into intimate mechanical contact using electrostatic actuation. Prototype devices have been tested in vacuum an demonstrate actuation voltages as low as 40 Volts, very good thermal insulation in the OFF state, and a la ease in radiative heat flow in the ON state.
