Patent ID: 7824075

Claim:
An apparatus comprising a device that includes: a radiation generator that, when energized, produces electromagnetic radiation that is emitted from said device; a thermal spreader that is larger than said radiation generator and that is disposed near said radiation generator for receiving heat emitted by said radiation generator; heat conducting structure for carrying heat from said thermal spreader to an end opposite said thermal spreader and said radiation generator, said heat conducting structure having an elongate portion adjacent said end, said heat conducting structure including a heat pipe that has, at all points along the length thereof, a cross-sectional shape with first and second transverse dimensions in respective directions that are orthogonal, said first transverse dimension being substantially greater than said second transverse dimension at all points along the length of said heat pipe; and heat dissipating structure spaced apart from said thermal spreader for accepting heat from said heat conducting structure at said end and for discharging heat externally of said device, said heat dissipating structure extending substantially radial to a central axis of said apparatus; wherein said heat dissipating structure includes a first plurality of fins having a first cross-sectional width and a second plurality of fins having a second cross-sectional width, said first cross-sectional width being larger than said second cross-sectional width, wherein said first plurality of fins has at least one hole sized to receive said end of said heat pipe.
