Abstract:
1. A system for cooling an enclosed volume having a yoke portion and a sphere portion, the yoke portion and the sphere portion having yoke and sphere surface areas respectively exposed to exterior air, the system comprising: a first hole in a shell of the sphere portion that aligns with and adjoins a second hole in the yoke portion; a first channel formed in the yoke portion that is adapted to receive air from an interior of the sphere portion via the first and second holes; and a first fan in the yoke portion that draws air from the interior of the sphere portion into the first channel, wherein the enclosed volume is substantially airtight such that air is prevented from flowing either from the interior of the sphere portion to the exterior air or from the first channel to the exterior air, and wherein heat is transferred from a hot spot in the interior of the sphere portion to the yoke portion via a flow of the air through the first and second holes and the first channel, and wherein the heat is further allowed to transfer to the exterior air via combined portions of both the yoke and sphere surface areas by conduction therethrough so as to more effectively cool the hot spot.
