Patent ID: 7332841

Claim:
A cooler mountable in a computer having a transparent case, comprising: a frame including a coil section having a plurality of windings spaced around an axis, a conductive first bearing disposed on an upper axial portion of the coil section, a conductive second bearing disposed on a lower axial portion of the coil section, and a rectification member attached to the frame, and being electrically interconnected to an AC power source and the coil section; a rotating assembly including a plurality of blades equally spaced around a hub coaxial with the coil section, a rotating conductive shaft attached to said hub and passed though the first and the second bearings with an insulative layer disposed on a portion of the shaft for insulating the shaft from at least one of said first bearing and said second bearing; and a magnet spaced around the coil section, the magnet reacting with the coil section to rotate the rotating assembly by applying DC current from the rectification member to the coil section; and a load placed on the rotating assembly and including a circuit board, and a plurality of light emitting elements; whereby applying AC to the rectification member will energize the coil section, rotate the rotating assembly, and activate the load causing the light emitting elements to emit light.
