Thermally-Managed Electronic Device

A thermally-managed electronic device, such as a heat-generating lamp or microelectronic assembly, takes advantage of the latent heat of phase-change within a heat pipe and functions in cooperation with a plurality of heat-radiating elements to enhance heat removal capacity from a heat source. The device, which may be provided in a natural convection or forced air convection embodiment, improves the heat removal on the cold side of the heat pipe by providing a much larger heat-radiating surface area in the form of a plurality of heat-radiating elements that are each thermally connected by means of one or more thermal connecting elements.
