Patent ID: 7733649

Claim:
An active cooling device comprising: a housing that supports means for emitting a fluid stream, the fluid stream emitted in a direction dependent on an orientation of said housing; a spindle mounted to the housing, the housing able to rotate about the spindle to change said direction in which said fluid stream is emitted, the spindle being mounted to the housing on a mounting plane parallel to the fluid stream, the mounting plane being offset from a bisection plane of the fluid stream, the bisection plane also being parallel to the fluid stream; such that when the fluid stream is emitted, a force exerted by the emitted fluid stream on said housing creates a moment about the spindle, said moment enabling rotation of said housing; and, retention means to retain the housing from rotating, wherein the retention means is removed upon a partial failure of one or more other active cooling devices, wherein upon removing the retention means, the housing rotates causing the direction in which said fluid stream is emitted to change.
