Zusammenfassung:	An inkjet printhead includes multiple inkjets arranged in a jetstack of the printhead. Each inkjet includes an inkjet nozzle and an actuator that controllably dispenses drops of a heat activated phase change ink according to a predetermined pattern. One or more heaters are arranged along the jetstack to heat the phase change ink to a temperature above the melting point of the ink. The printhead includes at least one pulsating heat pipe thermally coupled to the jetstack.
