Abstract

A cooling system is provided for enclosed volumes having payloads of electronic or other equipment that are susceptible to failures when overheated. One particularly useful application of the present invention is in a cooling system for a turreted gimbaled system (i.e. a gimbal) that includes electronic and optical equipment typically used for surveillance, but many other applications will become apparent to those skilled in the art after being taught by the present disclosure. According to one aspect of the invention, a cooling system includes a pair of reciprocal openings between a gimbal sphere and yoke allowing for passage of air therethrough and a pair of fans for circulating the air between the sphere and yoke, thereby expanding the surface area available for heated air from the interior to conduct into the exterior air. In another example, a heat exchanger is provided in the yoke to allow further cooling of the circulated air. In another example, a heat pipe is provided in the yoke to allow heat to be transferred to the heat exchanger.
