THERMAL MANAGEMENT SYSTEM AND METHOD FOR SPACE AND AIR-BORNE SENSORS

摘要

According to one embodiment, an apparatus includes an optical sensor having one or more thermally sensitive components. The sensor is gimbal mounted on a space or air-borne vehicle and includes a heat sink component thermally coupled to the one or more thermally sensitive components via at least one heat strap and configured to at least passively receive and store thermal energy from the one or more thermally sensitive components without use of a motorized thermal energy transfer device. The apparatus also includes a radiator configured to receive thermal energy from the heat sink component and to dissipate thermal energy to an ambient environment. The radiator is disposed on a first side of an optical path of the sensor opposite a second side of the optical path on which the heat sink component is disposed. The heat sink component is configured to at least partially balance a center-of-gravity of the sensor.
