1. A portable device, comprising:a thermal module containing a vapor region and a liquid region for a working fluid, disposed within an outer casing of the portable device, wherein the thermal module comprises a titanium backplane, a vapor cavity and wicking structure formed on a metal substrate;
at least one structural element that gives the portable device strength and stiffness;
an integrated circuit chip in thermal communication with the thermal module such that heat generated by the chip is distributed throughout the portable device by the thermal module; and
wherein the thermal module is coupled mechanically to the at least one structural element by at least one of soldering, welding, swaging, bonding and gluing, adding stiffness to bending out of the primary plane of the portable device.
