Patent ID: 7474529

Claim:
An assembly comprising: one or more heat-producing devices each having an exposed substantially planar surface; a folded heatsink formed from a continuous sheet of metal for cooling the heat-producing devices, the folded heatsink comprising: a base having a first end and a second end and lying substantially parallel to the exposed substantially planar surface of one or more of the heat-producing devices and affixed in thermal contact thereto; two shoulders each having a proximal end and a distal end, said proximal ends of said shoulders projecting substantially at right angles from said first and second ends of said base; and two arms each having a proximal end and a distal end, said proximal ends of said arms projecting substantially at right angles from said distal ends of said shoulders such that the base, shoulders and arms form a nearly closed rectangular tube; and a finned heatsink in contact with the planar surface of one or more of the heat-producing devices that are not in contact with the folded heatsink.
