A net-shape molded composite heat exchanger is provided which includes a plurality of thermally conductive fins overmolded onto one end of a metallic heat pipe for use both as an antenna in a cellular telephone and a heat exchanger to dissipate the heat generated within the device. The heat exchanger is formed by net-shape molding the fins over one end of the heat pipe, from a thermally conductive composition, such as a polymer composition. The molded heat exchanger is freely convecting through the part, which makes it more efficient and has an optimal thermal configuration. In addition, the metallic heat pipe serves the additional function of conducting radio frequency waves to and from the cellular telephone device.
