发明名称 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.

主权项 1. An apparatus comprising: an optical sensor comprising one or more thermally sensitive components, the optical sensor configured to be mounted to a space or air-borne vehicle via a gimbal, the optical sensor including a heat sink component thermally coupled to the one or more thermally sensitive components via at least one heat strap, the heat sink component configured to passively receive and store thermal energy from the one or more thermally sensitive components through the at least one heat strap without use of a motorized thermal energy transfer device; and a radiator configured to dissipate the thermal energy to an ambient environment, the radiator disposed on a first side of an optical path of the optical sensor opposite a second side of the optical path on which the heat sink component is disposed such that the heat sink component at least partially balances a center-of-gravity of the optical sensor with respect to the gimbal; wherein the heat sink component is thermally coupled between the radiator and the one or more thermally sensitive components, and wherein the radiator is configured to receive the thermal energy from the heat sink component.
